CONDITIONS ACROSS THE AREA HAVE BEEN SLOWLY IMPROVING IN THE WAKE
OF THE STRONG WINTRY SYSTEM THAT CROSSED THE AREA OVERNIGHT. WINDS
THAT REMAINED QUITE STRONG THIS MORNING ARE EXPECTED TO DROP OFF
FAIRLY QUICKLY OVER THE AFTERNOON AS THE PRESSURE GRADIENT LOOSENS
OVER THE AREA, WHICH WILL HELP REDUCE ANY LINGERING BLOWING AND
DRIFTING SNOW. ONCE THE WINDS DECREASE, WOULD EXPECT TO BE ABLE
TO DROP THE REMAINING WINTER HEADLINES LATER THIS AFTERNOON AND
EVENING.
QUIETER CONDITIONS THEN RETURN TO THE REGION FOR THE OVERNIGHT
PERIOD AS SOME CLEARING MOVES INTO THE AREA. WITH FRESH SNOW AND
CLEAR SKIES, A COLDER NIGHT ONCE AGAIN LIES AHEAD FOR THE REGION,
WITH LOW TEMPERATURES IN THE SINGLE DIGITS TO LOW TEENS. TUESDAY
MORNING WIND CHILL READINGS WILL LIKELY BE BETWEEN ZERO AND TEN
BELOW.
THE NEXT CLIPPER SYSTEM WILL BE IN THE WORKS FOR TUESDAY AFTERNOON
AND EVENING. WITH LIMITED MOISTURE AND A FAIRLY COLD AIRMASS IN
PLACE, ADDITIONAL SNOW WILL BE SOMEWHAT LIMITED WITH THIS NEXT
CLIPPER. MOST OF THE AREA WILL LIKELY SEE AN INCH OR LESS OF
SNOWFALL, WITH A FEW LOCALLY HIGHER TOTALS GETTING CLOSER TO 2
INCHES. COLDER AIR FOLLOWS IN THE WAKE OF THE NEXT CLIPPER, WHICH
WILL BRING BACK A PERIOD OF LAKE EFFECT SNOWFALL TO THE REGION FOR
THE MIDDLE OF THE WEEK. TEMPERATURES WEDNESDAY NIGHT WILL BE
PARTICULARLY COLD, WITH WIND CHILL READINGS IN THE MORNING RANGING
BETWEEN 15 TO 25 BELOW ZERO.
