DISCUSSION
AFTER A SUNNY AND DRY MORNING, LOOK FOR INCREASING CLOUD COVER AND
SCATTERED SNOW SHOWERS FROM 3-10PM. OCCASIONAL/BRIEF VISIBILITY
REDUCTIONS ARE POSSIBLE, AND ANY ACCUMULATION SHOULD BE A HALF
INCH OR LESS. WITH TEMPS RISING TO NEAR FREEZING THERE SHOULD BE A
LITTLE MELTING TODAY. MELTING WILL BE MINIMAL SATURDAY WITH TEMPS
IN THE 20S AND NORTHEAST WINDS. WHAT'S LEFT OF THE SNOW COVER
WILL MELT EARLY NEXT WEEK WITH TEMPS IN THE 50S BY MONDAY. NEXT
WEEK WILL ALSO SEE AN INCREASE IN WEST WINDS. WE DON'T EXPECT ANY
STRONG WIND EVENTS AT THIS TIME, BUT IT WILL BE GENERALLY BREEZY
FOR MOST OF NEXT WEEK (GUSTS IN 20S AND 30S). THIS WILL BE
SOMETHING TO MONITOR.
