Another round of showers and storms this weekend
A super-soaking weather system moved through the Valley Thursday, dropping as much as 0.75″ to nearly 1.25″ of rain throughout the region through 8pm.
The rain is gone for early commute. Roads are still wet, so allow yourself extra time!
At this time, very little — if any — lightning has been detected with this system. Nevertheless, track the heavy rain with WHNT.com’s Interactive Radar or swipe over to the radar feature on Live Alert 19!
Big-time soaking: The drought has been ongoing for almost a year now, and some communities have been hit harder than others. Northeast Alabama is missing a lot of rainfall; in fact, it would take almost a foot of rain to get out of the drought in Jackson, Marshall, DeKalb, Blount and Cullman Counties. Madison, Morgan, Limestone Counties and The Shoals area needs around 3 to 4 inches of rain.
While we don’t see totally even rainfall through the next seven days, the potential exists for as much as 1-2″ area-wide in all between now and next Monday.
Some communities will get a lot more than that: possibly exceeding 4 to 5 inches total!
That would go a long way in restoring ponds, lakes, and rivers, but we need more than one or two soakings to set us up in a better position going into the Spring growing season. We didn’t get into this drought overnight, and we won’t get out of it overnight either.
Saturday and Sunday: stormy in the region Got weekend plans here at home or somewhere else in the region? The weather may bring a substantial impact at times! A very warm (possibly record-setting) air mass over the South will serve to fuel some heavy thunderstorms both Saturday and Sunday.
On Saturday, the threat includes us in the Tennessee Valley, but the greatest chances are along the gulf coast; on Sunday, the threat is still mainly southeast of the Tennessee Valley region:
In North Alabama, Saturday looks to stormy with locally heavy rainfall during the afternoon.
The rain and storms move northward on Sunday, but the greater threat remains south of US 278 where the ‘best’ mix of fuel and dynamics will be placed.
So, you should expect a small chance of showers/isolated storms Saturday and a better chance of rain (at times locally-heavy) on Sunday.
When does it get cold? We’ve been saying for a while now that the cold weather is coming, but where is it? The first batch of ‘cooler’ air moves in Monday; it’s still not cold by January standards for most of the week, though.
Expect a gradual shift from the unusually warm to seasonably chilly weather late next week (Thursday and Friday) as the upper air pattern changes from ridge over the South to a deep trough coming in from the North.
There may even be a threat of some wintry mischief just beyond the end of next week. Things sure change fast this time of year!
