LOW PRESSURE WILL CONTINUE TO TRACK EAST OF THE AREA WITH HIGH
PRESSURE SURGING EASTWARD OVER THE AREA. WINDS WILL CONTINUE TO BE
BLUSTERY AS THE HIGH MOVES IN OVERNIGHT...WITH A SLACKENING OF
WIND THROUGH THE DAY THURSDAY. POCKETS OF BLOWING SNOW WILL
CONTINUE TO BE AN ISSUE IN EXPOSED AREAS THIS EVENING AND INTO THE
EARLY OVERNIGHT HOURS. TEMPERATURES WILL REMAIN BELOW AVERAGE AS
THE COLD AND DRY AIR ASSOCIATED WITH THE RIDGING MOVES INTO MAINE
FROM THE NORTHWEST. CLEARING SKIES AND FRESH SNOWPACK WILL COMBINE
WITH THE COLD AND DRY AIRMASS FOR SOME OF THE COLDEST TEMPERATURE
READINGS OF THE SEASON SO FAR TONIGHT.

HIGH PRESSURE WILL REMAIN IN CONTROL THROUGH THE END OF THE

APPROACHING STORM SYSTEM. THIS STORM SYSTEM IS EXPECTED TO TRACK
WELL TO THE NORTHWEST OF THE AREA...HOWEVER...A FRONTAL SYSTEM
ASSOCIATED WITH THE LOW WILL CROSS NORTHERN AND EASTERN MAINE
SATURDAY INTO SUNDAY WITH SHOWERS POSSIBLE. DEPENDING ON THE EXACT
TRACK OF THE PARENT LOW OVER EASTERN CANADA THE PRECIPITATION MAY
BE A MIXED BAG OF SNOW/RAIN. IN EITHER CASE...IT APPEARS THAT THE
PRECIPITATION WILL BE ON THE LIGHTER SIDE SO AT THIS POINT THERE
ARE NO HAZARDS EXPECTED.
