There is increasing confidence in the possibility of a significant severe weather event in our area. This will be an event that will bring multiple rounds and multiple modes of severe weather. A few strong storms could develop as early as tomorrow afternoon but this activity will be very spotty in nature. We will also be keeping an eye on severe weather to our west tomorrow. There is a chance a cluster of storms in this region could hold together and reach Alabama early Monday morning. These storms should be weakening as hey reach our area but I can't rule out some being severe with the primary threat being damaging straight-line winds.
A second round of severe weather will be possible Monday night and early Tuesday. Low level instability values are forecasted to be much higher for this round and wind profiles are forecasted to grow more conducive to severe rotating storms. Any storms late Monday night and into Tuesday will have to be monitored closely. These environments can produce the supercell type storms capable of producing long track tornadoes.
The center of the primary storm system responsible for this setup will be moving very slowly across the northern plains. This will create one of those unique setups in which the severe threat will linger. A disturbance rounding the base of the main low over the northern plains will approach late Tuesday. This will bring yet another threat of strong to severe thunderstorms that will linger Tuesday night and early Wednesday. All modes of severe weather will be possible including damaging straight-line winds, severe hail, tornadoes, and flash flooding. The severe threat should finally end late Wednesday as cooler/stable air flows into the state.
Now is the time to make preparations and review your tornado safety plan. Make sure you have a way to receive weather alerts during the overnight hours. It would also be a great idea to check on your emergency supply kit. We will continue to provide frequent updates online and be sure to join us for updates beginning at 9 p.m. on Fox 6 WBRC.
