Sunny Sunday but Wet Monday

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

A surface high settles in over the Southeast US today, so even with a chilly start as temperatures dip near the freezing mark, plenty of sunshine should see afternoon highs climb into the middle and upper 50s, not quite as warm as yesterday, but still a bit above the 30-year average highs for this date. Vic Bell up in Black Creek reported a low of 27 this morning with a good frost. But the overall weather pattern remains very fast, so there is something new on the horizon just about everyday this week. These fast systems are sometimes referred to as clipper systems as the move by at a fast clip!

Clouds increase tonight and early Monday with some showers possible Monday morning but widespread rain and showers by afternoon and evening. There are some slight timing differences in the models but confidence is high that we’ll see rain in the afternoon and evening. Fortunately we remain somewhat mild with highs Monday again in the middle and upper 50s. The upper trough moves off the East Coast on Tuesday as another trough dives into the Central US. This diving short wave will bring another round of cold weather to the eastern US as we see the 540 height contour reach all the way to the Gulf Coast once again.

Wednesday morning we may see some snow showers or snow flurries as strong cold air advection occurs. Wednesday will be a raw kind of day with highs struggling to get out of the 30s. We should see some sunshine by afternoon as the clouds depart with the upper trough. Morning lows on Thursday morning will again drop back into the 20s. That trough moves into northern New England but yet another strong impulse digs into the Upper Midwest on Thursday and into the Southeast by Friday – did I mention that these systems are clipping right along!! Because of the rapid succession of these systems, it seems highly unlikely that we’ll see more than clouds since moisture will have a very hard time to recover. But the strong amplitude of the short wave moving through the long wave trough position Friday means another shot of cold air with lows Saturday morning falling back into the 20s. Saturday will be another relatively raw day with highs in the 40s.

Sunday the pattern dampens just a tad allowing Central Alabama to return to seasonal temperatures with lows around 32 and highs in the lower 50s.

The GFS continues to hammer away at a continuous parade of strong impulses moving through the overall long wave trough position. The pattern makes it difficult for moisture to make a significant return, but the strong impulse around the 24th could provide some winter weather mischief for the Southeast US. And it is followed quickly by another strong short wave with potential for winter mischief depending on moisture recovery. No rest for the folks in the weather department.
