The latest data shows a wetter scenario ahead of an approaching cold front on Friday. The NAM is a little slower with the arrival time of showers and storms. It shows showers possible in the morning hours and early PM and then showers and storms arriving after 7pm from NW to SE. A strong storm or two can't be ruled out across Marion, Lamar, Winston and Cullman county if this model run pans out of the NAM. The RPM data shows an earlier arrival time of showers and storms. It's also a wetter scenario than compared to the NAM. See below the RPM images to get an idea of what might be in store for us on Friday into Saturday morning.
FRIDAY AT NOON: Pre-cold front showers and storms will be possible, greatest chance NW.
FRIDAY AFTERNOON: Data suggests scattered showers and storms developing and impacting areas along and west of the I-59/I-20 corridor.
FRIDAY EVENING: A band of showers and storms passes by. Main threats this early out include locally heavy rainfall and lightning. If this timing pans out then some football games will likely be impacted, especially towards the middle to end of games. Keep checking back for forecast updates as we track this developing storm system.
SATURDAY MORNING: Before the front passes through, rain will still be possible across east Alabama.
We will continue to monitor model trends and hopefully see more timing and coverage consensus by tomorrow.
Start planning ahead now for Friday evening outdoor activities to potentially be impacted by rain and storms.
Thanks and have a great day,
