More Typical Summer Pattern Going On, Rain Chances a Little Higher Over Weekend

Thursday (High 90, Low 70): Partly cloudy. Isolated showers and thunderstorms are possible.

Friday (High 89, Low 71): Partly cloudy. Widely scattered showers and thunderstorms are possible.

Saturday (High 88, Low 72): Partly to mostly cloudy. Scattered showers and thunderstorms are possible.

Sunday (High 87, Low 71): Mostly cloudy with a 50% chance of showers/thunderstorms.

Monday (High 87, Low 69): Partly to mostly cloudy with a 40% chance of showers/thunderstorms. 

Tuesday (High 88, Low 68): Partly cloudy with a 30% chance of showers/thunderstorms. 

Wednesday (High 89, Low 66): Partly to mostly sunny with a 20% chance of showers/thunderstorms. 

At 4:15 PM skies have cleared behind a thunderstorm in Cullman. The temperature is 79 degrees. The dewpoint is 73, making the relative humidity 84%. Winds are from the South/Southwest at 5 miles per hour. The pressure is 1015.72 millbars, or 30.04 inches, and steady. It is partly sunny and 91 in Jasper, mostly sunny and 88 in Haleyville. 

We had a High of 86 and Low of 72 in Cullman today. Looks like 91 will be the High for Jasper after a Low of 73 this morning. Haleyville saw a High of 90 and a Low of 73. 

 Showers and thunderstorms across the Southeast region have been widely scattered today, like you'd expect on a summer's day. 

A lot of the storms have producing a lot of lightning, also typical for the summer months, and we're into July now, time flies. Those storms back in Missouri and Illinois might be worth watching for our region later tonight, although most of the time, such storms weaken or fizzle down to light rain by the time they get down this way. 

We are mainly under the influence of high pressure in the region, but our winds are westerlies, bringing us the scattered rain. 

We'll see more widely scattered showers and thunderstorms on the map tomorrow, High near 90, Low near 70. 

As we get toward the weekend, the broad ridging will give way to broad troughing at the upper levels of the atmosphere. A 30% chance of rain looks reasonable for Friday. I think tomorrow might deserve only 20%. So that's just isolated rain or storms. For Friday, High about 88-89, Low near 70. 

For Saturday will go with a 40% chance of rain and similar temperatures, upper 80's for the High, near 70 for the Low. 

And I'll hold that for Sunday, might drop temperature for daytime by a degree or two. 

By Monday our upper-level flow will be Northwesterly, and any thunderstorms we get, might have to look out for a mesoscale convective system, which can produce strong winds and/or some hail. Think will keep rain chance at 40%. Might go 50% for Sunday now looking at overall pattern. Monday should feature a High in mid/upper 80's, Low in upper 60's.

Then some drier air will drop in here for Tuesday and Wednesday of next week. Tuesday we can drop the rain chance back to 30%, High in upper 80's, Low in mid/upper-60's. 

Then for Wednesday, can drop the chance back to 20%, High in upper 80's, Low more toward mid-60's, might actually see more sun than clouds by then. 

Tropics are quiet. 

The summer weather around here is more typical now, if anything maybe a little mild temperature-wise and a little wetter than a lot of July's.
