PATCHY FROST LOOKS POSSIBLE FOR THE RIDGE VALLEYS AND WILL TAKE A CLOSER LOOK FOR NEXT UPDATE.
A WEAK COLD FRONT IS MOVING ACROSS THE REGION THIS MORNING WITH WINDS BECOMING MORE NORTHERLY ALL THE WAY TO THE COASTAL WATERS. BEHIND THE SECOND SHORT WAVE THE FLOW ALOFT WILL BECOME MORE NORTHERLY AS A RIDGE BUILDS OVER THE PLAINS. THIS WILL SERVE TO PUSH IN A DRIER, COOLER, AND MORE SEASONABLE AIR MASS OVER THE AREA TODAY THAT WILL LINGER THROUGH SUNDAY.

850 TEMPS 00Z SATURDAY TOPPED OUT AT 6C AND SHOULD BE NEARLY 10C WARMER BY 00Z SUNDAY. A SFC WARM FRONT HAS ALREADY FORMED TO OUR WEST OVER THE DAKOTAS AND WILL MOVE RAPIDLY EAST TODAY. WHERE SLIGHTLY COOLER AIR WILL STILL RESIDE HIGHS WILL REACH THE LOWER 70S AND IN THE WEST TEMPERATURES SHOULD BE CLOSING IN ON THE UPPER 70S. WESTERLY FLOW ALOFT IN PLACE TONIGHT WITH SOUTHWESTERLY LOW LEVEL FLOW AND WAA IN ADVANCE OF A DEVELOPING AREA OF LOW PRESSURE CENTERED OVER THE PRAIRIE PROVINCES OF CANADA. THIS LOW IS ASSOCIATED WITH AN UPPER LEVEL WAVE MOVING THROUGH THE ROCKIES.
Temperatures along and south of the front are in the lower 70s, while well behind the boundary, temperatures are in the upper 40s in southeastern Alabama. Once the fog burns off after sunrise, weak high pressure over the region will keeps winds minimal and allow temperatures to warm into the lower to mid 70s this afternoon.
