Partly to Mostly Cloudy At Midday, Some Tricky Weather Ahead Tonight

At the 11 o’clock hour for Central Alabama, skies are partly to mostly cloudy across the southern half of the area, with partly to mostly clear skies for the northern half. The cold front that moved through on Tuesday stalled out during the overnight hours in South Alabama, and has begun a journey to the north as a warm front. A trough with an associated cold front is making its way toward the state, and is causing advection out ahead of it. Our dewpoints will be on the increase today, and we may have enough ingredients tonight for a few strong to severe storms.

This evening could be very interesting with a chance of severe storms moving in after 10:00 PM and going through the early morning hours on Thursday. The Storm Prediction Center currently has nearly all of northern half of the state defined in a “Marginal Risk” for severe storms on their Day 1 Severe Weather Outlook. The cold front that pushed slowly through our area on Tuesday stalled out over the extreme southern parts of the state. This front will start to move back northward as a warm front later this afternoon and evening. Another cold front will be moving into the area tonight and is expected to strengthen as it arrives.

Throughout the day today, skies will be partly to mostly cloudy, and a stray shower or two is possible for the western half of the area. Afternoon highs will be in the mid 60s to mid 70s across the area from north to south. The main window for thunderstorms and the possibility for strong to severe storms will start in the northwestern corner of the area between 9PM-11PM, progressing to the Birmingham Metropolitan Area by 12AM-2AM, and reaching the Gadsden/Anniston area by 1AM-3AM.

The main threats for tonight’s event will be from strong straight-line winds and small hail, but a few tornadoes cannot be ruled out at this time. Instability (CAPE) values will be on the low end, around 300-700 J/kg, with dewpoints increasing into the low to mid 60s ahead of the cold front. If enough instability is allowed to develop, there will be enough shear to support supercellular storms, and enough to support updrafts.

Before going to bed, just make sure you have your weather radio and another reliable source of receiving severe weather information close by. We’ll have updates on the blog throughout the day on this developing situation.
