...SNOW AND WINTRY PRECIPITATION IS EXPECTED IN THE NORTHWEST FOR
THE NEXT FEW DAYS...
...A CLIPPER SYSTEM IS FORECAST TO PRODUCE SNOW TO THE GREAT LAKES
AND NORTHEAST THROUGH THE MIDDLE OF THE WEEK...
...A FRONTAL SYSTEM WILL BRING WINTRY PRECIPITATION TO THE
MIDWEST, GREAT LAKES, AND MID-ATLANTIC, WITH SHOWERS AND
THUNDERSTORMS EXPECTED IN THE SOUTHEAST TO END THE WEEK...
IN THE PACIFIC NORTHWEST AND NORTHERN INTERMOUNTAIN WEST, A
STATIONARY FRONTAL SYSTEM WILL CONTINUE TO BRING UNSETTLED WEATHER
OVER THE NEXT FEW DAYS. A STRONG INFLUX OF MOISTURE ORIGINATING
FROM THE PACIFIC ALONG WITH STRONG LOW-LEVEL ONSHORE FLOW WILL AID
IN GENERATING PRECIPITATION FROM NORTHERN CALIFORNIA TO WESTERN
WASHINGTON. PRECIPITATION IN THE COASTAL REGIONS IS EXPECTED TO
REMAIN IN THE FORM OF RAIN, WHILE UPSLOPE REGIONS/HIGHER ELEVATION
AREAS WILL EXPERIENCE SNOW AND WINTRY MIX. TOWARDS THE END OF THE
WEEK, AN AREA OF HIGH PRESSURE WILL MOVE INTO THE REGION,
WEAKENING THE FRONTAL SYSTEM AND PUSHING IT FURTHER SOUTH. AT THIS
POINT, PRECIPITATION WILL DIMINISH IN MOST AREAS, WITH REMNANT
PRECIPITATION BEING MUCH MORE ISOLATED AND CONFINED TO THE UPSLOPE
REGIONS.
AN ONGOING CLIPPER SYSTEM IS FORECAST TO PROGRESS EASTWARD THROUGH
THE GREAT LAKES REGION THROUGH THE MIDDLE OF THE WEEK. THIS WILL
BRING HEAVY SNOW FOR THE PARTS OF THE GREAT LAKES AND THE DOWNWIND
REGION OF THE GREAT LAKES BEGINNING EARLY WEDNESDAY MORNING,
BEFORE MOVING FURTHER INTO NEW ENGLAND. THE FRONTAL PASSAGE WILL
BRING STRONG NORTHWESTERLY WINDS ALONG WITH IT, CAUSING BLOWING
SNOW AND DIFFICULT TRAVEL.
BEGINNING ON WEDNESDAY, AN UPPER-LEVEL TROUGH IS EXPECTED TO BEGIN
AMPLIFYING OVER MUCH OF THE PLAINS. THIS WILL AID ANOTHER FRONTAL
SYSTEM IN THE NORTHERN PLAINS TO QUICKLY MOVE SOUTHEASTWARD
STARTING WEDNESDAY, REACHING THE MID-ATLANTIC AND SOUTHEAST ON
THURSDAY INTO FRIDAY. THIS SYSTEM IS EXPECTED TO BRING SNOW AND
MIXED PRECIPITATION TO THE NORTHERN/CENTRAL PLAINS AND THROUGH
PARTS OF THE MISSISSIPPI VALLEY ON WEDNESDAY NIGHT, BEFORE MOVING
INTO THE LOWER GREAT LAKES, MID-ATLANTIC, AND THE NORTHEAST ON
THURSDAY. MEANWHILE IN THE SOUTHEAST, THIS FRONTAL SYSTEM WILL
BRING SHOWERS AND THUNDERSTORMS BEGINNING ON THURSDAY THROUGH THE
END OF THE WEEK.
ABOVE-AVERAGE TEMPERATURES ARE SET TO CONTINUE FOR MUCH OF THE
WEST OVER THE NEXT SEVERAL DAYS, INCLUDING THE SOUTHWEST AND THE
SOUTHERN PLAINS, DUE TO THE INFLUENCE OF AN UPPER-LEVEL RIDGE.
TEMPERATURES IN THE SOUTHWEST WILL BE ESPECIALLY WARM, WITH HIGHS
IN PARTS OF ARIZONA AND SOUTHERN CALIFORNIA EXCEEDING 90 DEGREES.
IN THE MID-ATLANTIC, TEMPERATURES ARE EXPECTED TO MODERATE
BEGINNING ON WEDNESDAY, WHILE BELOW-AVERAGE TEMPERATURES ARE
EXPECTED FOR THE GREAT LAKES AND NORTHEAST AS THE AFOREMENTIONED
CLIPPER SYSTEM MOVES THROUGH.
