BIRMINGHAM, AL (WBRC) - THE LATEST ON THE SEVERE THREAT FOR TOMORROW NIGHT: Confidence is increasing in the possibility of severe weather across parts of the region tomorrow night. While this will be one of the more significant threats the region has seen in quite some time, the main threats for our area will be in locations to the northwest. Late tomorrow night as the low level flow intensifies and jet stream energy pivots across the region, severe storms capable of producing damaging winds, hail, and tornadoes are expected to materialize over north central Mississippi, Northwest Alabama, and middle Tennessee. These will be the types of discrete-supercell storms that could produce longer track tornadoes. This threat will include our far northwest counties like Marion, Lamar, and Winston counties. This will be the greatest risk zone for severe weather in our area. As far as timing, we will need to monitor this area closely after 10 PM, although the peak threat timing will be between midnight and 5 a.m. on Tuesday. As the system moves east, the rain and storms should develop into more of a line and gradually push east across our area. The potential for a strong to severe storm will continue in areas northwest of the I-59 corridor, however the storm intensity should gradually lessen throughout the morning, as the line moves further east, with a more marginal and lower severe risk for locations south and east of the I-59 corridor. So basically we continue to be most concerned about a threat in areas north of a line from Tuscaloosa to Birmingham and Gadsden. We will need to monitor closely just in case this setup becomes a bit more amplified. I would certainly be weather ready by having multiple ways of receiving severe weather alerts overnight. We have a FREE Weather app you can download by searching WBRC in your App Store and make sure you have fresh batteries in your All Hazards NOAA Weather Radio.
FIRST ALERT FOR RAIN TONIGHT: Changes will begin to take place this evening as an axis of rain impacts the area. A band of light to moderate rain is entering our western counties and this will impact the area throughout the night. Lows tonight will be in the 50s. Tomorrow will be a warm and breezy day. I can’t rule out a few scattered showers or a stray storm but the main rain and storm impacts will hold off until late tomorrow night.
ELECTION DAY: While storms will be a concern early Tuesday morning, the line will rapidly weaken as it marches east, with big improvements during the day on Tuesday. So we should have some clearing as we head out to cast our votes on Election Day.
MORE RAIN BY LATE WEDNESDAY: I’m expecting a good supply of sunshine on Wednesday but the front associated with Tuesday mornings storm system will end up stalling and returning north Wednesday night. This will bring a good chance of rain beginning late Wednesday night and continuing throughout the day on Thursday. The greatest coverage of rain will be across our southern counties. A much stronger cold front will arrive early Friday morning and this system could spark some storm development before drier air returns. Some of the storms to our far south may have some instability to tap into early Friday morning so we will need to monitor this region for a possible severe threat. We should rapidly clear out by the weekend, with a colder air mass settling in. Highs next weekend will only reach the upper 50s, with lows at night nearing the freezing mark. I will have much more on tomorrow’s nights storm threat in any forecast beginning at 9 p.m. on WBRC FOX6.
