An area of clouds was moving across the northern half of Alabama this morning, but it looks like we will still see a good deal of sun with highs climbing into the 70s once again.

Moisture begins returning to the area as the surface high continues to slide eastward. Aloft the closed low that was off the southern California coast a few days ago comes out of the four corners area as an open trough. A surface low associated with the trough will move northeastward dragging a cold front into the Mississippi River region Sunday afternoon. This should increase the shower and rain threat for us come Sunday evening and into the early morning hours of Monday.

SPC has a large area of slight risk for severe weather stretching all the way from the central Rio Grande Valley to Iowa. The primary threat of severe weather appears to be severe thunderstorms with damaging wind. However, due to the marginal nature of the wind shear, isolated tornadoes may occur with the stronger storms.

That front will move across Alabama Monday with some marginal threat of severe weather in the form of isolated wind damage in the area from northern Mississippi and Northwest Alabama northeastward into the Ohio River Valley. The threat is likely to peak with the afternoon heating on Sunday.

The front moves through Monday so we should see improving weather by afternoon. Since the air will be coming out of the Pacific, we’ll see a cool down but nothing extreme.

Another trough along with a surface front is likely to develop Wednesday and bring us a shower threat on Thursday. At the moment, the moisture return seems somewhat limited so I expect to see scattered showers and thunderstorms, so it might not give everyone rain. This front moves through quickly paving the way for great weather on Friday and Saturday.

Tropics have become active with Patty dissipating to a remnant low while Rafael move in on Puerto Rick. Rafael is expected to move northward over the next several days, affecting Bermuda late Tuesday.

Looks like we’ll see dry weather through the first part of week two with another rain event possible around the end of October.

I’m enjoying some great storytelling at the Tale Tellin Festival in Selma, AL. Delores Hydock and Carmen Deedy are great tellers and the Dill Pickers add a lot to the show with their incredible music. Fun stuff. I even share a stor or two during the Swappin’ Grounds, a chance for amateur storytellers to do their thing. I expect to have the next Weather Xtreme Video posted first thing Sunday morning. Enjoy the day and Godspeed.
