Warm Temps, Rain and Strong Storms Ahead… Thursday Update 3:15 PM
January 5, 2012 Leave a comment
A good Thursday afternoon to you! After a chilly start to the day, temperatures warmed very nicely this afternoon. Many spots have made it well into the upper 50s or lower 60s. Tuscaloosa is reporting 63 as of 3pm. Temperatures will start to fall again tonight, with an average low of 34 degrees. Some spots to the northeast of Birmingham will likely get another light freeze, but upper 30s are expected to the southwest of Tuscaloosa. As moisture levels rise, temperatures at night will continue to rise over the next few days.
The eastern US trough has moved out of the area, and a modifying airmass is developing over much of the central and southern US. This is in response to some ridging across the south. Plus, an area of high pressure southeast of Alabama is allowing a warm and moist airmass to advect in from the Gulf of Mexico. Temperatures may reach 70 in spots on Friday and Saturday, as the ridge continues to pump up across the south. Clouds will increase as moisture increases, but many areas will stay dry on Friday. A weak cold front will move into north Alabama on Saturday and Sunday. This front will serve as a focal mechanism for showers and light rain. At this point, I don’t expect anything heavy over the weekend, but some spots may pick up 1/4th of an inch both Saturday and Sunday. The front will stall across central Alabama, as the upper air support pushes northeast of the area.
An upper level low will dig deep across the southern Rockies and Plains on Sunday. This system will push east on Monday and Tuesday. A surface low will develop over the northern Gulf of Mexico and lift northeast into Alabama on Tuesday and Tuesday night. They dynamics and shear are impressive with this system, so we’ll have to keep an eye out on the threat for severe storms. That threat all depends on the track and strength of the surface low. Some data puts the low in a favorable spot for active weather locally, but this is still several days out and will likely change. Keep it here for updates on our blog and on WVUA-TV. Either way, instability will be limited with this system, so that should prevent any major problems. If instability levels rise, that statement may change. This system will likely produce lots of rain late Sunday, Monday and on Tuesday. Highs will remain in the 60s to around 70 through Tuesday, but cooler air will follow behind the front on Wednesday and Thursday.
