High pressure at the surface will dominate our weather today. We'll see an abundance of sunshine, but temperatures will be slightly cooler than yesterday. Highs should top out around 54 this afternoon. A tight pressure gradient will remain in place today and result in another windy day with some gusts up to 30 mph. The pressure gradient will relax substantially overnight as high pressure will be centered over the area. With very light winds, dry air, and clear skies in place, temperatures should easily be able to drop below freezing tonight. Lows tomorrow morning will be near 28.
Temperatures will temporarily warm up Wednesday and Thursday before our next storm system arrives on Friday. We'll have to watch this system closely for the threat for winter weather as the weather pattern favors a suppressed storm track. Combined with a surge of modified arctic air, the potential is in place for a significant winter storm across the South. I think our area will remain all rain except for a brief changeover to freezing rain at the end of the event. However, I think residents in North Alabama should prepare for some major headaches. Much colder air will filter into the state for the weekend, and highs will stay in the 30s Saturday and may struggle to break 40 on Sunday as strong northwest winds will blow over a snow and ice pack.
