RAW, COLD DAY: Clouds have been hanging tough over much of Alabama today, keeping temperatures in the 38-43 degree range at mid-afternoon. Quite a slap in the face after the mild weather we enjoyed last week. Even down at Gulf Shores our SKYCAM is showing a chilly 48 degrees at 2:30.
The big upper trough west of the state will pass through tonight and early tomorrow, and that should bring rain to parts of the Gulf Coast, including places like Pensacola and Panama City, and up into Southeast Alabama around Dothan. We stay dry up here, but the clouds will stick around tonight and early tomorrow.
The sky becomes partly sunny during the day tomorrow, and we warm up a bit with a high in the mid 50s.
THURSDAY/FRIDAY: These two days will be dry with a slow warm-up. We reach the upper 50s Thursday, and Friday’s high will be close to 60 with a good supply of sunshine both days.
THE ALABAMA WEEKEND: Moisture levels will rise in response to a storm system forming over the nation’s mid-section. The 12Z GFS is a little more aggressive with the development of showers during the day Saturday; looks like we will need to mention some risk of rain at times Saturday through Sunday morning; rain amounts still look light with less than 1/2 inch for most places. The high over the weekend will be in the low 60s both days.
NEXT WEEK: Both the GFS and the ECMWF are on board with a major cold core upper low swinging over Alabama Tuesday. We all know strange things can happen under a cold core; dynamic cooling can bring snow flakes when you don’t expect them. Low level thickness values here suggest just some cold rain at times for this part of Alabama Tuesday; any snow most likely would come over Tennessee. So, while things could change, for now it just doesn’t look like a snow look for Alabama on Tuesday.
VOODOO LAND FUN: Snow lovers tend to watch every model run this time of the year, going over the data with a fine toothed comb looking for the magical freezing line at 850 mb, and the 5400 meter 1000-500 mb thickness line (which can represent lines where it is “cold enough to snow”). The 12Z GFS shows a good snow look for North Alabama on December 22, followed by very cold air on through Christmas Day. Nothing but pure speculation for now… see the Weather Xtreme for the maps and details.
WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. Scroll down for the show notes on this week’s new episode we recorded last night. Great to have Kevin Laws of the Birmingham NWS on with us.
