First Alert Weather Day: An increasing tornado threat across our area, tornado watch will be likely

FIRST ALERT Weather: 6 am update 4/12/2020

BIRMINGHAM, Ala. (WBRC) - INCREASING TORNADO RISK THIS EVENING: A powerful storm system is approaching our state and pulling a very unstable air mass north into Alabama. This will bring an increasing risk for severe storms capable of producing large tornadoes. A tornado watch will be likely for this evening.

At the time of this update, our team was tracking severe storms producing tornado warnings near Kosciusko, MS. These storms have a history of producing significant damage further west in places like Monroe, LA. These storms are the first ones that need to be closely monitored as they approach West Alabama.

We continue to fine-tune the timing and initially the greatest severe risk will be north of I-20, starting to the west after 4PM, with storms possibly tracking as far east as Gadsden by 8PM.

The primary severe risk will reach places like Tuscaloosa and Birmingham after 7PM and then continue into East Alabama, between 8PM and 1AM. All modes of severe weather will be possible, including the threats of golfball size hail, damaging winds, and large long-track type tornadoes.

A WIND ADVISORY is also in effect through 3AM tomorrow morning. Winds will be out of the south at 15 to 25 mph, possibly gusting as high as 35 mph. I’d have a flashlight nearby just in-case there are power outages.

WHAT TO EXPECT THIS WEEK: The severe risk will end by 2AM tomorrow morning, with big improvements for the start of the week. Sunshine will be returning for Monday, with highs in the 70s. It’s going to feel cooler for Tuesday, with another good supply of sunshine. We may see a few isolated showers late Tuesday night and into Wednesday, however this system will quickly exit with more sunny weather for Wednesday and Thursday. Some of the coldest weather can be expected early Thursday morning, with lows near 42º. Also, I want to give you the First Alert for the possibility of patchy frost early Thursday morning.

STAY WEATHER ALERT: Be sure to check in for updates on the news at 5PM and also at the top and bottom of the hour on WBRC. If warnings are issued, we will break in to track the severe weather. Remember you can find our LIVE Stream on the WBRC First Alert Weather App and also hear us on iHeart Radio Stations in the area.
