A CLIPPER SYSTEM MOVING THROUGH THE GREAT LAKES AND
APPALACHIANS/NORTHEAST WILL BRING UNSETTLED WEATHER ACROSS THE
REGION TODAY (THURSDAY). SCATTERED LIGHT TO MODERATE RAIN SHOWERS
CAN BE EXPECTED ACROSS PORTIONS OF THE MID-ATLANTIC AND CAROLINAS
WHILE A MESSY MIX OF RAIN AND SNOW IS EXPECTED FOR HIGHER
ELEVATIONS OF THE APPALACHIANS AS WELL AS FURTHER NORTH INTO THE
INTERIOR NORTHEAST/NEW ENGLAND. SOME LIGHT TO MODERATE SNOW TOTALS
CAN BE EXPECTED FOR HIGHER ELEVATIONS OF UPSTATE NEW YORK/NEW
ENGLAND AS WELL AS LOCATIONS CLOSER TO THE CANADIAN BORDER THAT
WILL SEE MOSTLY SNOW. SOME LAKE-ENHANCED LIGHT TO MODERATE SNOW
TOTALS ARE ALSO LIKELY DOWNWIND OF LAKES ERIE AND ONTARIO.
PRECIPITATION FOR MOST LOCATIONS SHOULD COME TO AN END BY FRIDAY
EVENING, LINGERING LONGEST FOR THE APPALACHIANS AND INTERIOR
NORTHEAST. THEN, ON FRIDAY, ANOTHER CLIPPER SYSTEM WILL DROP
SOUTHWARD FROM CANADA AND INTO THE UPPER GREAT LAKES BRINGING A
SWATH OF MODERATE TO LOCALLY HEAVY SNOWFALL. THE SYSTEM WILL SWING
EASTWARD ACROSS THE LOWER GREAT LAKES/INTERIOR NORTHEAST BY FRIDAY
EVENING BRINGING ADDITIONAL LIGHT TO MODERATE SNOWS. THE HIGHEST
TOTALS ARE MOST LIKELY ACROSS HIGHER ELEVATIONS OF UPSTATE NEW
YORK AND DOWNWIND OF LAKE ONTARIO. ELSEWHERE, THE COUNTRY WILL BE
MOSTLY DRY. A LOW PRESSURE SYSTEM MOVING THROUGH SOUTHERN
CALIFORNIA MAY BRING SOME SHOWERS AND THUNDERSTORMS BY LATE
FRIDAY/EARLY SATURDAY.
MOST OF THE COUNTRY WILL CONTINUE TO SEE ABOVE TO WELL ABOVE
AVERAGE TEMPERATURES AND MILD CONDITIONS TO END THE WORK WEEK. IN
THE EAST, FORECAST HIGHS THURSDAY GENERALLY RANGE FROM THE 30S AND
40S IN NEW ENGLAND, THE 40S AND 50S IN THE NORTHERN MID-ATLANTIC,
AND THE 60S AND 70S IN THE SOUTHERN MID-ATLANTIC INTO THE
SOUTHEAST. A COLD FRONT PASSAGE WILL BRING HIGHS DOWN BY ABOUT 10
DEGREES ON FRIDAY, BUT THIS WILL STILL BE AT OR A BIT ABOVE
AVERAGE FOR MOST LOCATIONS. FOR THE CENTRAL U.S., FORECAST HIGHS
THE NEXT COUPLE OF DAYS RANGE FROM THE 40S AND 50S ACROSS THE
NORTHERN PLAINS AND GREAT LAKES; THE 50S AND 60S FOR THE CENTRAL
PLAINS, MIDDLE MISSISSIPPI VALLEY, AND OHIO VALLEY; AND THE 60S
AND 70S FOR THE SOUTHERN PLAINS. INTO THE WEST, HIGHS ARE EXPECTED
TO BE IN THE 50S AND 60S FOR THE PACIFIC NORTHWEST AND GREAT
