Rain and thunder returns, followed by much cooler air. Halloween weekend looks mostly okay though.
It's been a beautiful Wednesday across the Tennessee Valley with mostly sunny skies continuing, and temperatures warming nicely into the upper 60s and lower 70s. We have no rain near our immediate area as of the time of this blog post, but some big storms are ongoing down to our southwest across Louisiana. A fairly significant tornado event has been ongoing since this morning across southeast Texas and into Louisiana, but all of this severe weather threat will stay way off to the south of the Tennessee Valley area.
We stay dry through the rest of the afternoon and the early evening, but rain and a few rumbles of thunder move back into the area during the late evening and overnight. Some of the rain may be heavy at times, but we don't expect any severe weather in our area. That continues in waves through the morning hours of Thursday before backing off to lingering showers into Thursday afternoon and evening.
Despite there being no real concern of severe storms (thunderstorms producing damaging winds, hail, or tornadoes), there will likely be gusty winds during the overnight tonight through about midday on Thursday as the frontal boundary pushes through. Wind gusts at or over 30 mph are possible over much of the area. For this reason, all of north Alabama is under a Wind Advisory through 1:00 PM on Thursday for the potential for wind gusts of 30 to 35 mph, but wind gusts near this range are possible in southern middle Tennessee as well. It would be a really good idea to secure your Halloween decorations this afternoon or evening unless you're fine with them being donated to your neighbors down the street LOL.
The trough cuts off into an upper low as it moves across, causing the storm system to take its time moving through the area. Showers will linger at times through Thursday night, Friday, Friday night, and Saturday morning before moving out of the area. Much cooler air moves in behind the front with daytime highs on Friday and Saturday only in the mid to upper 50s! High pressure shifts back toward the area going into Sunday, with temperatures moderating back toward the mid and upper 60s from Sunday into the first part of next week.
The good news is that showers clearing out during the morning on Saturday means that trick-or-treating weather on both Saturday and Sunday evenings looks alright. The ground may still be a bit damp or muddy, and kids will need to carry along a jacket, but I don't expect anybody to get rained on Saturday evening, and definitely not on Sunday. Sunshine returns in earnest by Halloween itself, with temperatures during the afternoon back into the mid 60s, with evening temperatures in the 50s through trick-or-treat time.
