NOTES:

The Memorial Day severe weather event did produce a couple of tornadoes, but they were down in Central Alabama. Nobody has put together a web page for the damaging wind reports across North Alabama early that morning, so I guess I was one of the few people that actually cared . . . 

This is sort of old news, but NOAA does predict that this hurricane season (which starts Saturday June 1st) will be an above average season. If you or someone you know will be staying along the coast this summer, it is a good time to go over your hurricane safety plan

I'm going to try 10-day outlooks again this summer and see how it goes. Sometimes I think the science still is not that good, but other times I wonder if it is the next logical step. Even if it is, there needs to be some way to let the public know when the forecast gets to a point of lower confidence in specifics. So I'm planning to tinker around with it. 

May 28 was the anniversary of Tropical Storm Alberto from 2018. 

I think "chubasco" is a better word to describe most of our summer showers than "lluvia", but I am not sure. 

DISCUSSION:

At 3 PM skies are sunny in Cullman with a temperature of 79 degrees. The dewpoint is 55 degrees, making the relative humidity 45%. And for those of you who haven't been outside much lately, let me tell ya', you can feel the difference with that lower humidity right now. It is a rare treat for us this time of year. Winds are calm. The pressure is 30.13 inches and fairly steady at the moment, but showing a slow falling trend over the last several hours, if you want to get technical. The Low this morning was 55 degrees. 

In Jasper it is sunny and 82 degrees. The dewpoint is 57, making the relative humidity 42%. Winds are calm. The pressure is 30.11 inches and let's go ahead and call it falling slowly. The Low this morning was 57. 

Haleyville is sunny and 78 degrees. The dewpoint is 58, making the relative humidity 50%. Winds are calm. The pressure is 30.16 inches/1020 millibars and falling slowly. The Low this morning was 56. 

It is mostly sunny and 83 degrees in Huntsville, with a dewpoint of 51, making the relative humidity 33%. Winds are from the West at 7 miles per hour. The pressure is 30.11 inches/1018.7 millibars and falling slowly. 

And skies are partly cloudy in Nashville with a temperature of 77, dewpoint of 49, which makes for a relative humidity of 37%. Winds are light and variable at about 3 mph. The pressure is 30.15 inches/1020.4 and I'm not going to say steady, but falling a little more slowly than at these other sites. 





Our severe weather season in the Southeast is over, and now we head into the summer months. The severe storms shift out to the Plains and Midwest this time of year, and we mostly just have heat and humidity, occasional random showers and thunderstorms to cool things off a little. Sometimes those summer storms do pulse up and produce some hail and/or strong winds, but even when they do, that doesn't last long. They rain themselves out quickly. Once in a while we get some coming out of a cluster (mesoscale convective system) in somewhere like Missouri, and they are in a weakening phase by the time they get here but can still produce enough wind to damage some trees or something. But overall summer is a quiet season for us. Those stronger storms are so hit-or-miss and are not worth worrying about that much. Just about the only time we get really organized severe thunderstorms in the summer is if a hurricane comes really far inland and brings us the threat of flash flooding, high winds, or an isolated tornado. Even then, we have to be in the right position relative to the remnants of the hurricane (mainly the Northeast quadrant). And it has to come really far inland, what's left of it. 

Which is a long-winded way of saying that a summer pattern is starting to establish around here and that it's usually quiet for the most part. Just hot and humid. Plenty of sunshine, to the point we get sick of it. But right now, I'll take a break from the severe storms. And it has been really comfortable out there lately, especially at night. It's almost like we're getting some credit for a really stormy May. 

We might get up to about 80 degrees today, skies staying sunny to mostly sunny, just a few fair weather clouds where we do see them. 



Tomorrow looks like another dry day, plenty of sunshine, more sun than clouds, rain chances so minimal, don't even worry about it, High near 85, Low near 57-58 tonight. 



The GFS wants to show a lot of rain coming in here on Saturday associated with a shortwave trough. 


And the NAM looks more realistic to me. The models do not always handle a summer pattern all that well around here. I think the GFS has the rain chances way too high and am only going to introduce a 30% chance of rain here, about a 1-in-3 chance of any one spot getting a shower or thunderstorm Saturday. Will mention partly cloudy skies. High in the lower-to-mid-80's and Low in the lower-to-mid-60's. 



Sunday looks like another mix of sun and clouds, rain chance of about 20-30%. And yes thunderstorms are possible. Or you may get just plain old rain. For any newcomers to summer around here, I explain these things. Or maybe I just like to pontificate. 

Again expecting a High in the lower-to-mid-80's and a Low in the lower-to-mid-60's. 

I know a lot of forecasts are calling for lower temperatures and higher rain chances, but I'm just having a hard time believing it. So I'm forecasting what I think it's really going to do. 



Monday the GFS shows another shortwave trough that might justify rain chances in the 30-40% bracket. So probably looking at a High in the lower 80's, Low in the mid-60's. 



Tuesday definitely going to cut the rain chance back to 20-30%. High should be in mid-80's, Low in mid-60's. I'm not showing the ECMWF here because that seems like a ridiculous level of detail for a going-into-the-beginnings-of-summer forecast. But I'm glancing at it as I go along. And it generally is showing a lot less convection than the GFS. So I'm probably going to trend the rain chances on the lower end before all is said and done here. 



Will maintain a 20% chance of rain Wednesday with a High in the mid-80's, Low in the mid-60's. 



Starting Thursday a ridge will start to build in our direction from out in the Plains. But we'll keep a 20% chance of rain in the forecast. Highs should climb into the upper 80's, Lows in mid/upper 60's. 



Then next Friday, the trend toward a high pressure ridge and drier air around here is more pronounced. Should probably keep a 20% chance of rain in there just for climatology. High would be in the mid-to-upper-80's and Low in mid-60's. 



Then Saturday the GFS is showing a low pressure system from the Appalachians bringing us some scattered rain, but PoP should top out at 30% here. High in mid-to-upper-80's, Low in mid-to-upper 60's.



Then on Sunday it shows rain chances lowering again as that system moves away. So would expect a High in upper 80's, Low in upper 60's, about a 20% chance of rain. 

Probably not going to be a day of taking the rain chances out completely in this forecast period, just taking into account climatology and common sense, past experience. 


We could see an average of up to two inches of rainfall during this forecast period, at least the next seven days. Isolated parts of the region might see closer to three inches or more. The showers and storms of summer are so hit-or-miss that sometimes I don't even post these maps. And I often don't post tiny severe thunderstorm probabilities from the SPC. Because I expect people to understand how things go in the summer. Those guys in Oklahoma can try to predict which of our summer thunderstorms will get to severe limits or come close, and where, but I'm not very interested in playing that game. Usually it's pretty random, or at least what causes them in certain places are fine mesoscale details that are not that well-understood yet. And the vast majority of them are general thunderstorms or just some rain. The general thrust of modern media, even a lot of these independent YouTubers, is where everything is constant drama and supposed to hit you in the face. And I'm going for the opposite with this weather blog. This is meant to be an oasis of common sense. A lot of people in the world of weather do cut through the hype, but even in meteorology, sometimes it gets ridiculous, the way things are advertised versus the way they really are when you dig into the details. Anybody who followed the Johnny Depp/Amber Heard drama knows what I'm talking about in the regular news. 

For anybody who follows the stories about my cats, Stormy has started to come out more and let me pet her, and even rub her head against me at times. Salem seems bothered by this, and walks up wanting to make sure he gets his equal share of attention. She still hisses and snarls at him most of the time, even though she's relaxing a little around me. He bites and claws me a lot more than she does, just playing rough. She only does that when she feels threatened, to tell somebody to leave her alone. And I've noticed she only does enough to get the message across. Since I always leave her alone after that, I've only gotten nibbles and mild swats. But right now, she is warming up to me, until she sees him walk up, then she becomes hostile again. 

If you're looking for some good reading to start the summer, I'd check out the new story collection by Stephen King. I pre-ordered it with some other books months ago and had forgotten about it until it came out recently. The first story ("Two Talented Bastids") is a good one with an outdoorsy-country and also sci-fi vibe. It's about 60 pages long, but once you get into it, it sort of flies by. 

And if you get too hot, drink Dr. Pepper. It is life. 

I know I'm supposed to tell you to drink water, which technically is better for rehydrating. But I'd throw some flavor in there too every now and then. It just wouldn't be summer without some carbonated beverages that are now contraband in public schools. I think the country was on the right track back when they let students have smoke breaks back in the 1970's. As one girl in my family tree put it, "And we can't even have candy!" I'm even less popular than most politically incorrect people these days. If it was up to me, adults would be able to choose whether or not they even wear seat belts in their cars. I think things were better when people had the freedom to cut them out. 

So if you're thirsty this summer, drink whatever ya' want. I am well aware that there are things that taste a whole lot better than Gatorade. 

I don't think even this anal-retentive modern world has a problem with lemonade. 

So there's our solution. If you've got a mom or grandma, ask for some lemonade when you go see 'em. it especially goes well with July . . . so you've got some time. Hasta luego.

Bare Bones Forecast

 Well another stormy night has ended, at least the severe weather threat for North Alabama and Southern Middle Tennessee. 

The rest of today any remaining showers and storms should remain widely scattered, and the bulk of the day will become mostly sunny with a High near 86. 

Tuesday looks sunny behind the front, drier air pushing in, we'll see a High in about the 83-85 range, a Low about 60-62. 

Maybe a few passing clouds Wednesday as we get a reinforcing dry front to bring even more cool dry air in here. High near 80, Low near 60. 

Then Thursday we feel the effects of that extra shot of cool dry air. Sunny skies and a High struggling to even make 80, probably just upper 70's. The morning Low should be down in the upper 50's or maybe even mid-50's. 

Sunny skies on Friday, High near 80 or so, Low in upper 50's. 

And then Saturday and Sunday, a few clouds coming back and chances for isolated rain, about a 20% chance, which translates to a 1-in-5 chance of any one spot getting a shower or thunderstorm. Highs should be in the lower 80's, Lows in the lower 60's. And these rain chances do not look any higher than on typical summer days. Which kinda' works since Saturday is the first day of June, meteorological summer. Also the first day of hurricane season technically but let's not jinx anything. 

We got off pretty good with this severe weather event. Sounds like we just had tree and power line damage around here, probably from straight-line winds, but they'll go out and survey it in case there was a tornado somewhere in the mix. We definitely got the leftovers with this one, and for some reason, even with supercells forming just ahead of the squall line and then merging with it, it didn't get anywhere near as bad as it could have. 



Nationwide it was a different story, numerous tornado reports, some did significant damage in the Plains and Mid-South on Saturday and then yesterday, the focus was more in Missouri, Kentucky, and Southern Illinois for tornadoes. Tons of damaging thunderstorm winds across the Ohio Valley and over into the Mid-Atlantic yesterday. A fair amount of large hail too, especially in Missouri where those supercells originally fired up that ended up producing so much tornado damage. The hail in those was pretty crazy too. 

Of course we don't have the final tally yet, and there are storm surveys to be done this week. 

But that's a quick look at things. I've heard of no injuries in North Alabama or from our neighbors up there in Tennessee. So with pleasant weather coming in, I feel like taking a cat nap, whether my cats want to nap with me or not. 

Hasta luego.

Severe T-Storm Warning


4:20 AM - Particularly for Cullman, Marshall, and Dekalb Counties, the National Weather Service in Huntsville is emphasizing that emergency management has reported numerous trees down and power outages in these areas. And that a tornado could quickly spin up in these areas. So folks in Cullman, Hanceville, down to Colony, and in Arab, Albertville, all the way up to Fort Payne, I'd go ahead and get to your safe place and stay there until these storms pass. Even if it's straight-line winds, the new warning was issued because of confirmed damage. 

Need to be in a small room or hallway on the lowest floor of a sturdy house, near the center of building, away from windows. 

4:33 - The line of these storms is about to Holly Pond now. Emergency management continues to report lots of downed trees and people without power from this group of severe thunderstorms. A tornado could quickly develop in this environment, but it doesn't take a tornado to do some damage. The winds can blow in a straight line and do this. Some small hail is also in these storms and of course lots of lightning. 

4:42 - These storms have weakened below severe limits as they push East/Southeast. So the warnings at least for Cullman, Marshall, and Dekalb Counties are being allowed to expire. 

4:44 - For anyone that follows my cat adventures, I was only able to get Salem into the center part of the house when one of those severe thunderstorm warnings looked a little too dicey for me to ignore. I have no idea where Stormy was. She might have been up behind a curtain in the window watching the storm. The two of them have fought a lot since we came out of cover. And I was just being extra cautious. Damage reported, low risk of a tornado spinning up, I ran the computer on battery power and got in the safer part of the house for a few minutes. Their antics are funny but exasperating sometimes . . . 



4:46 - A severe thunderstorm warning remains in effect until 5:15 AM CDT for Blount, Etowah, and Cherokee Counties. 

That big green polygon is a swath of counties affected by a Flash Flood Warning, includes Huntsville. 

And those tan boxes like in Lamar County in West Central Alabama are Special Weather Statements for strong thunderstorms that are staying below severe limits. 

4:55 - A severe thunderstorm watch has been extended down into Central Alabama. 

4:58 - Got a severe thunderstorm warning for Lamar and Fayette Counties. The threat is really shifting into Central Alabama more than North Alabama per se now. 



5:03 AM - The Tornado Watch has been cleared for all the counties served by the National Weather Service offices in Huntsville and Nashville. And no further severe weather is expected for North Alabama.

Tornado Warning



3:08 AM - And somebody might need it in Spanish . . . 


So here be another graphic. This includes places like Brownsboro and Gurley. Hard to confirm at night, but it does look pretty impressive on radar. 

Well just as soon as I said that, the next volume scan showed much weaker rotation. But you have to respect warnings tonight. Storms cycle up and down. And sometimes in this kind of a setup, a storm can produce several brief tornadoes in the same general area, where you see rotation on the radar. 


3:13 - And now we have a new Tornado Warning polygon that includes Hytop and Scottsboro. The polygon affects Madison, Jackson, and Marshall Counties. 



3:15 - Here's a really good look at who's in this new polygon. 



3:17 - And we also have a large Flash Flood Warning polygon from about Moulton and Hartselle through Huntsville up to Winchester. 

Also a Severe Thunderstorm Warning for Northeast Jackson County and clipping Northern Dekalb County, mainly the community of Ider there. 

3:21 - The rotation looks weak on radar at the moment, but in these polygons, still need to stay in a small central room or hallway on the lowest floor of a sturdy house, away from windows. 

New tornado warning . . . just going to post the new one below, the graphics and describe. Not going to make a new post for every single warning like this, every polygon. Because that would get pretty confusing after a while, too many posts. 



New Hope, Guntersville, Albertville, and Geraldine in Marshall and Dekalb Counties are included in this new warning polygon. 

Also the town of Grant in this new polygon for the new tornado warning. 



3:36 - Had technical problems and had to reboot, this new Tornado Warning is mainly for Arab. 

This does include Eva and far Northeast Cullman County like Baileyton and Holly Pond. Also Union Grove, Guntersville, Albertville, and Douglas and Boaz in Marshall County included in this new warning. 

And by the way, what I was trying to post when the connection went out briefly . . . Cullman, the city, is now included in a Severe Thunderstorm Warning. So wouldn't be a bad idea to stay in a safe place there even though it is more likely to be damaging straight line winds. It carries a note that tornadoes can develop very quickly in this environment. 

3:40 - And right here are our only severe thunderstorm left to deal with in North Alabama at the moment. Unfortunately more than one segment appears to be trying to produce brief tornadoes. And those are still dangerous. Even if only on the ground for a minute or two, or five or ten minutes, any tornado is dangerous. Need to get to shelter and stay there. 



3:43 - And now we have a Severe Thunderstorm Warning that extends all the way over to Fort Payne in Dekalb County. Wouldn't hurt to shelter to some extent from these warnings for damaging straight line winds too. Sometimes in a squall line overnight, it's tough to tell the difference really. 



3:46 - Sort of good news, our only remaining Tornado Warning is the storm affecting Eva, Baileyton, Arab, Guntersville, down to Boaz. The ones further to the Northeast have been let go. Some severe thunderstorm warnings are still in effect for damaging winds and hail in NE AL though. 



3:51 - Ok that new severe thunderstorm warning actually includes almost all of Dekalb County and Southern Jackson County, places like Hollywood and Scottsboro. 



3:52 - Zooming in on our one Tornado Warning at the moment, looks like the best chance of seeing a tornado right now is near Arab. But anywhere in this polygon, please respect the warning and stay sheltered. Because in a situation like this, sometimes more than one tornado can quickly spin up within the same general area. They can come and go really fast. And you want to be in a safe place in case of that and also from any damaging straight-line winds or hail such a severe thunderstorm may be producing apart from a tornado. 


3:55 - The Tornado Watch has been cleared early for Lauderdale, Colbert, Franklin, Limestone, and Lawrence Counties. And it has also been cleared for all of our Tennessee Counties just across the border there. The rest of North Alabama is still under it as this squall line moves through and some supercells merged with it. 

And it looks like they'll clear Madison County from the watch soon too. 

3:59 - The tornado warning is cancelled for Marshall County, radar update incoming . . . 




4:02 AM - We have a Severe Thunderstorm Warning still in effect for Northeast Cullman County, into Morgan County, Marshall County, Dekalb County, and Southern Jackson County. Damaging winds and some hail are possible in these storms. And in tonight's environment where some damage has been reported to trees and power lines at times, it is best to play it safe. 

Since the tornado warning has been let go, going to start a new post of the Flash Flood Warnings since really haven't caught up with that.
