SUNNY DAY. NOT AS COLD MONDAY NIGHT...BUT STILL FROSTY IN SOME
INTERIOR LOCALES. AS A LOW PUSHES EAST TOWARD THE REGION MONDAY

OF THE FRONTAL BOUNDARY. COOLER AND DRIER AIR WILL MOVE IN BEHIND
THE FRONT...BUT MIN TEMPS WILL REMAIN WELL ABOVE FREEZING.

THIS BOUNDARY IS EXPECTED TO STALL SOUTH OF THE REGION WED...AND
THEN LIFT BACK NORTH AS A WARM FRONT WED NIGHT INTO THU. GFS IS A
LITTLE FASTER WITH PUSHING THE ASSOCIATED LOW PRESSURE SYSTEM ACROSS
THIS RUN...WITH CURRENT TIMING STILL IN THE THU NIGHT TIME FRAME. AT
THIS POINT...IT LOOKS LIKE THE BEST CHANCE FOR SIGNIFICANT PRECIP IS
THU INTO THU NIGHT. HIGH PRESSURE THEN BUILDS INTO THE REGION FRI
AND SAT.
