Cold air relaxes in the East as the Drought worsens in the South

A major early spring warm up is underway from the Central Plains east to the Eastern seaboard. As areas that saw there heaviest snows of the year will be in the 70s by tomorrow and the upcoming weekend. So let the melting begin as an strong southern flow takes over. Here is this weekend's big snow storm snowfall across the South and East Coast.

These area will be seeing above normal temperatures as the drought plaqued area of the Southern Plains will be baking in near record heat. Here is the GFS models predicted high temperatures for Thursday and on Sunday. As you can see lower 90s are forecasted for me here in SW Oklahoma. As 60s and some 70s are widespread across the Ohio Valley and Mid Atlantic on Sunday.


With this warmer air will also come with more moisture as some severe weather will be possible. Right now the models differ on some parameters needed for severe weather. So exact timing, strength and locations of the storms are unknown. The threat is increasing both Saturday and Sunday but again Monday and Tuesday with storm system #2. Storm system number one will push a dryline/cold front across the Central and Southern Plains over the weekend. This could spark some severe t'storms across Kansas and Oklahoma Saturday evening. Then over eastern Oklahoma and Northeast Texas on Sunday. Right now Storm Prediction Center (SPC) only mentions the threat of severe weather on Sunday. Here is that latest outlook for then.

This warm up will be short-lived as more cold air poised for the Eastern U.S. and for the Plains as well. More on this later.....
