Cold and raw
A very tricky weather situation lies ahead today, particularly early. An upper level disturbance will quickly pass over the region today. This system is expected to conjure up enough moisture to produce some scattered pockets of precipitation today. Meanwhile, cloud cover and north-northeast winds are reinforcing cold air on an already freezing morning. However, we also have very dry air aloft. That means any precipitation falling initially will evaporate and help to slowly saturate the air. In any event, should we saturate quickly enough and with temperatures hovering around freezing for a few hours this morning, there is a small window open for an ice pellet or snowflake to mix in with rain-likely limited to the Florida Parishes and Southern Mississippi. Surface temperatures have been warm enough in the last few days that no impacts are expected if any wintry precipitation falls. In all likelihood, today will just be overcast with some chilly rain showers.
Thursday's storm is a quick mover and will be beyond the region by tonight. In fact, you can expect a partial break up in cloud cover. Holes in the clouds will allow more "warmth" at the earth's surface to escape into the atmosphere allowing a very cold night; most of us will end up in the upper 20s by Friday Morning.
