STILL DEALING WITH LIGHT SNOW AND AREAS OF BLOWING SNOW ACROSS THE

LAKES. RADARS ACROSS THE AREA ARE SHOWING DECREASING ECHOES WITH
BREAKS IN THE SNOW AS WELL. EXPECTING A GRADUAL END TO THE SNOW
FROM WEST TO EAST THROUGH THE EVENING HOURS. WILL KEEP WINTER
STORM WARNINGS IN PLACE FOR RIGHT NOW AS GUSTY WINDS AND LOW VSBYS
ARE STILL BEING OBSERVED. HAVE ISSUED A WIND CHILL ADVISORY FOR
LATER TONIGHT ACROSS THE WESTERN HALF OF THE CWA AS THE ARCTIC AIR
MASS BEGINS TO MOVE IN. NORTHWEST WINDS WILL REMAIN BREEZY AND
WILL BE DEALING WITH 20 BELOW AND COLDER WIND CHILLS AFTER
MIDNIGHT. DECIDED TO LEAVE THE EASTERN COUNTIES OUT OF IT FOR
RIGHT NOW BECAUSE IT APPEARS MORE MARGINAL AS LOW TEMPS ARE
EXPECTED TO BE WARMER. WILL HAVE TO MONITOR THOUGH. IT DID NOT
SEEM AS IF THE EASTERN COUNTIES WOULD GET SOLIDLY INTO CRITERIA
UNTIL THURSDAY EVENING. RAN ALL WIND CHILL HEADLINES THROUGH 00Z
SATURDAY. WIND CHILL VALUES WILL COME OUT OF CRITERIA DURING THE
DAY THURSDAY...BUT FOR WHAT ITS WORTH...WILL STILL BE RATHER
BREEZY WITH VERY COLD WIND CHILLS SO WILL LEAVE IN PLACE TO AVOID
CONFUSION AND ALSO KEEPING IMPACTS IN MIND.

SATURDAY/SUNDAY/MONDAY BRINGING THE CHANCE FOR SOME ADDITIONAL LIGHT
SNOW...ESPECIALLY ON SUNDAY. PRECIP WILL HAVE TO FIRST OVERCOME
THE DRIER AIR NEAR THE SFC UNDER HIGH PRESSURE. THE CLOUD COVER
FROM THE TROF WILL HELP TO MODIFY TEMPS ONLY SLIGHTLY. NORTHWEST
FLOW ALOFT ON MONDAY AND TUESDAY WILL SEND WIND CHILL VALUES BACK
