Sunshine and Mild Temperatures Through the Weekend

Thursday (High 85, Low 67): Mostly sunny.

Friday (High 83, Low 60): Sunny.

Saturday (High 82, Low 61): Sunny.

Sunday (High 83, Low 61): Sunny.

Monday (High 86, Low 63): Mostly sunny.

Tuesday (High 84, Low 64): Partly to mostly sunny with a 20% chance of a shower or thunderstorm.

Wednesday (High 82, Low 63): Partly cloudy with a 30% chance of showers/thunderstorms. 

Right now we've got strong thunderstorms moving through Cullman with visibility down to 9 miles, temperature of 77 degrees, dewpoint 75, relative humidity of 94%. Winds are from the West at 5 miles per hour. Have generally been West/Southwest today. Pressure is 29.98 inches and rising slowly at the moment. Skies have been mostly sunny today, but these isolated thunderstorms have moved in later in the day and now the night hours, different parts of the state. Things have actually gotten more organized back in Mississippi, where a Severe Thunderstorm Watch is in effect. Today's High for Cullman was 88, and the Low this morning was 70. 

So we have a cold front around about Memphis that is getting into our region. That's bringing the thunderstorms, and it's a little ahead of schedule. Back on Saturday, it looked more like this thing would get here Friday of this week. But it sped up. 

And it actually looks like we'll get a frontal passage tonight. I've been out of the weather loop since Saturday, had some other stuff going on, so am catching up here. But it looks like a mostly sunny day tomorrow behind this front with  High of about 85, not a huge cooldown, but not as warm as today was. Then Friday through Sunday, looks like our upper-level winds will be from the North/Northwest, and we'll see plenty of sunshine, Highs in the lower 80's and Lows hovering around the 60-degree mark. 

Looks like we'll warm up a little bit on Monday, mid-80's anyway, as the flow becomes more zonal. 

Then the flow is more from the Southwest on Tuesday, with a little moisture coming back into the region, still probably more sun than clouds. 

But Tuesday and Wednesday, looks like bringing back a 20% chance of showers, Highs in lower 80's, Low in lower to mid-60's. 

In the tropics, we have Hurricane Lee, expected to become a major hurricane by Saturday. 

Everyone from the Leeward Islands down to Puerto Rico needs to monitor the progress of this storm, as the impacts from a really major hurricane can extend far beyond the center, even if that's as minor for some areas as swells and dangerous rip currents. And frankly, as we go into next week, people on the East Coast of the mainland United States need to monitor this, to be on the safe side. Because not even the best long-range global models know exactly where this is going yet before any landfall it might make after whatever it does with some islands this weekend. And at least through early next week, it is expected to reach and maintain major hurricane status. This could even be a rare Category 5 hurricane. It looks really powerful. So everyone potentially in the path of this thing needs to keep an eye on it and make sure their hurricane safety plan is ready to go. 

The National Weather Service in Birmingham is holding SKYWARN classes soon. Before we get into November, which some years, turns out to be our secondary severe weather season in North Alabama, also up into Tennessee. 

After the storms tonight though, our weather looks quiet for a while. And temperatures look pretty mild overall. Though not quite as cool as some people expect for early September. It varies from year to year, how quick Fall comes in.
