We're in a weather pattern with one round of active weather after another. Severe storms are again possible across our area this afternoon and evening. Instability values could reach over 2,000 j/kg based on some model data. Temperatures this afternoon will reach the upper 70s to lower 80s. This would allow for some intense updrafts supporting the development of large hail. It appears the best chance for severe storms will come after 1pm and continue through 10pm. Models are suggesting conditions are not as favorable for tornado development. However, some storms could produce some gusty winds over 60mph.
Where: Greatest risk for strong to severe storms West of I-65 - especially in Marion, Winston, Lamar, Fayette, and Walker Counties.
Impacts: Winds over 30mph with some storms possibly producing winds over 60mph. Large hail is possible up to 1.5" in diameter.
Timing: 1PM through 10pm.
Call to Action: Be weather aware this afternoon and evening. If you have a garage or shelter, park you car inside because of the hail threat. Make sure you have several ways to receive weather alerts including the WBRC First Alert Weather app.
What's Next? Forecast models are also indicating more thunderstorms coming up late Thursday. The primary threat will be gusty straight-line winds. Greatest potential for stronger storms appears late afternoon and evening. The best day this week for outdoor plans will be Wednesday.

We'll see a few spotty showers and thunderstorms today - especially during the afternoon as temperatures climb into the upper 70s. While we're not expecting severe weather today, we could see a few storms producing some intense lightning and an occasional heavy downpour. The high this afternoon will near 80 degrees in places. Overnight lows will fall into the lower 60s.
FIRST ALERT MONDAY: Another round of showers and storms will develop on Monday during the late afternoon and evening. These storms could produce some hail and gusty winds. The greatest potential for strong storms is west of I-65 and especially Northwest Alabama. Expect the thunderstorm potential around 60-percent. Remain weather alert during the late afternoon and evening hours. Counties where we could see the strongest storms include Marion, Winston, and Lamar.
We are between systems on Tuesday and Wednesday with much drier weather expected. Temperatures will reach the mid to upper 70s with morning lows in the upper 50s.
FIRST ALERT THURSDAY: Another round of possibly strong to severe storms will impact the area. Again, the likely time to watch will be afternoon/evening. The primary threat will be damaging winds.
Calmer weather is expected on Friday and through the weekend. In fact, we should see the return of sunshine on Saturday with mild temperatures. Highs will reach the mid to upper 70s.
FIRST ALERT UPDATE: There is a slight chance for showers after 7AM across west Alabama, otherwise it looks dry on Saturday morning. The main round of showers and storms are set to move in during the early afternoon hours to the west of I-65. The stormy corridor looks to impact the I-65 corridor during the early evening hours and after dark to the east of I-65.
SHOWING YOU POSSIBLE STORM ARRIVAL TIMES:
There will be a narrow zone of greatest instability and wind shear that will set up across west Alabama during the afternoon hours. Areas west of I-65 could see a strong or severe thunderstorm between 1pm-6pm. Greatest storm risk is the potential for damaging straight line winds. There will be a limited tornado threat too and lastly hail is possible but below severe criteria which is 1” in diameter.
Most storms will just be heavy rainfall and lightning producers and create wet roads and low visibility for drivers.
Keep up with this forecast through the WBRC First Alert Weather App. Subtle timing changes in the arrival times of storms are still possible and we will be the first to let you know.
