High pressure extended from the Dakotas to the Sabine River Basin this morning as another nor’easter is cranking up off the Atlantic Coast.
The nor’easter will not be in any hurry to move away from New England, leaving the only direction for the Dakotas high-pressure to move is south or south-southeast towards Mississippi. The area of high-pressure will be centered over the Florida Panhandle on Thursday. This will gradually turn winds onshore, elevating the humidity and warming temps.
Clear skies, dry air, and a fairly light wind regime should be the story the next 3 days. We could see patchy frost in sheltered areas, mainly to the north of the coastal counties during the next 2 nights. Highs will be in the mid and upper 60s through Thursday. An area of low-pressure will move out of the Rockies, and across the middle Mississippi River Valley Thursday night through Saturday, before finally pushing a front across the area Saturday night. One push of precipitation will be Friday night, with a second on Sunday/Sunday night.
SEVERE THREAT will be across almost all of Arkansas, and parts of Mississippi north of Interstate 20. Temperatures will be near normal on Friday and well above normal for Saturday through Monday.
