High humidity from about 20,000 feet to 35,000 feet above the ground has kept high-altitude cirrostratus overcast over most of our area today, and those clouds were just thick enough to block any appreciable warming effects from the sun, holding temperatures in the lower and middle 40's all around the area today. The clouds will stick around tonight and act like a blanket to help keep our temperatures from chilling over too much. A cold wind flow will carry cold air into the region, and as cold as the air will be it would be colder without the clouds. A low pressure trough axis west of us will move east toward us and help push that humid layer of air away from us on Wednesday. That low pressure trough will also initiate a new low pressure area at the surface over the northern Gulf, and up until today it looked as though that low may mean some rain for areas along and south of Highway 84. Today's models suggest that rain will happen, but farther southeast and away from any parts of our area. The sun will help to warm temperatures into the 50's Wednesday afternoon, but the lack of clouds to trap that warmth Wednesday night will combined with a light wind beneath high pressure will set us up for what may be the coldest night so far this cold season. Temperatures along I-20 and Highway 80 (Meridian, Newton, Decatur, Livingston, Demopolis) will be around 24-25; south of I-20 (Waynesboro/Laurel/Bay Springs) expect 28-30; well north of I-20 (Philadelphia, DeKalb, Louisville, Macon, Geiger) could drop into the 21-23 degree range. As the mid-level low pressure wave kicks eastward, high pressure at the surface will build across our area and expand toward the northeast. A slow eastward progression will continue with the high pressure cell so that its center is to our east by Friday. West of the center a warmer wind will ease the icy feel in the air and temperatures will warm a bit going into the weekend. Another low pressure wave will drag a cold front through the area late Saturday, and that will mean another shot at rain for us. The cold front stalls to our south Sunday and Monday and the baroclinic zone will initiate new low pressure development Monday afternoon. That may push a few showers into our far southern areas late Monday, but any rain on Monday will be restricted mainly to areas along and south of Highway 84. That low, though, will push northeast and will mean some significant rain for our area on Tuesday. It will also draw cold air into our area from the south, and if that cold air flows in a little faster than currently forecast, and if the moisture lingers a little while longer than currently forecast a few snow flakes could mix in at the end of the rain on Tuesday. I do not expect this to happen. I am merely throwing this out as a possibility IF things come together a little differently.
