DISCUSSION...
COLD AND DRY AIR MASS WILL BRING A FREEZE TO MOST AREAS TONIGHT...
BUT INCREASING HIGH CLOUDS COULD LIMIT THE OVERNIGHT COOLING OVER
SOUTHERN COUNTIES. THE HIGH CLOUDS SHOULD ALSO HOLD BACK HIGH TEMPS
A FEW DEGREES THURSDAY. A LAYER OF MID LEVEL CLOUDS ARE EXPECTED
THURSDAY NIGHT WITH LIGHT RAIN DEVELOPING FROM THE SOUTH EARLY
FRIDAY MORNING. FLAT ZONAL PATTERN ALOFT MEANS THE WEAK
DISTURBANCE COULD LEAVE A WEAK AND BRIEF SUBSIDENT FEATURE TO
BRING SOME FAIR SKIES FOR SATURDAY INTO EARLY SUNDAY. HIGH CLOUDS
AND MOISTURE SHOULD INCREASE QUICKLY WITH LIGHT RAINS PROBABLE TO
DEVELOP AGAIN LATE SUNDAY INTO MONDAY NIGHT. THE SHORTWAVE TROUGH
TO ENHANCE PRECIPITATION MONDAY IS SHOWN IN CONSISTENT MODEL RUNS
TO BE STRONGER WITH SIGNIFICANT DRYING AND MORE COLD AND DRY AIR
FOR TUESDAY INTO WEDNESDAY. TEMPS THROUGH MOST OF THE 7-DAY
FORECAST WERE ADJUSTED DOWNWARD FROM GFS BASED GUIDANCES SINCE AS
THE ICE ACCUMULATION OVER THE CENTRAL AND NORTHERN US SHOULD BE
INFLUENTIAL.
