...LOCALLY HEAVY RAINS AND STRONG WINDS ARE EXPECTED FOR PORTIONS
OF THE NORTHERN MID-ATLANTIC AND SOUTHERN NEW ENGLAND THROUGH
TONIGHT...
...HEAVY WET SNOW AND STRONG WINDS ARE EXPECTED ACROSS PORTIONS OF
THE NORTHERN APPALACHIANS TONIGHT THROUGH SUNDAY FOLLOWED BY
LAKE-EFFECT SNOWS ACROSS THE LOWER GREAT LAKES INTO MONDAY
MORNING...
...UNSETTLED WEATHER IS EXPECTED ACROSS THE PACIFIC NORTHWEST AND
INTO THE NORTHERN ROCKIES AS MULTIPLE ROUNDS OF LOWER-ELEVATION
RAIN AND HIGHER ELEVATION SNOW ARRIVES...
MULTIPLE CONSOLIDATING AREAS OF LOW PRESSURE ALONG WITH THE
ARRIVAL OF A COUPLE OF COLD FRONTS ALONG THE EASTERN SEABOARD WILL
YIELD AREAS OF HEAVY PRECIPITATION OVERNIGHT, AND PARTICULARLY
FROM PARTS OF THE NORTHERN MID-ATLANTIC AND INTO THE NORTHEAST.
THIS WILL INCLUDE LOCALLY HEAVY RAIN FOR PORTIONS OF EASTERN
PENNSYLVANIA AND NEW JERSEY UP ACROSS SOUTHEAST NEW YORK AND INTO
SOUTHERN NEW ENGLAND. AS A CONSOLIDATED AREA OF DEEPENING LOW
PRESSURE APPROACHES AND CROSSES THROUGH SOUTHERN AND EASTERN NEW
ENGLAND, LOCALLY STRONG WINDS, ESPECIALLY FOR NEW ENGLAND CAN BE
EXPECTED AS WELL.
SUFFICIENT COLD AIR IS EXPECTED TO FILTER SOUTH INTO THE NORTHERN
APPALACHIANS TO ALLOW FOR THE RAIN OVERSPREADING AREAS OF NORTHERN
NEW YORK AND NORTHERN NEW ENGLAND TO CHANGE OVER TO SNOW LATER
TONIGHT INTO SUNDAY, AND AS MUCH AS 6 TO 12 INCHES OF HEAVY WET
SNOW CAN BE EXPECTED ALONG WITH STRONG GUSTY WINDS AS LOW PRESSURE
LIFTS NORTHEAST ACROSS THE REGION. LOCALLY HEAVIER SNOWFALL TOTALS
CAN BE EXPECTED OVER THE HIGHER PEAKS OF ESPECIALLY VERMONT, NEW
HAMPSHIRE AND MAINE. ON THE BACK SIDE OF THE DEPARTING AREA OF LOW
PRESSURE, COLDER AIR WILL BE SURGING SOUTHEAST ACROSS THE GREAT
LAKES AND INTO MUCH OF THE MID-ATLANTIC AND NORTHEAST, AND THIS
WILL GRADUALLY FAVOR AREAS OF HEAVY LAKE-ENHANCED SNOW SHOWERS AND
SQUALLS. PORTIONS OF THE LOWER GREAT LAKES AND EVEN THE CENTRAL
APPALACHIANS ARE EXPECTED TO SEE LOCALLY OVER 6 INCHES OF SNOW
FROM THE LAKE EFFECT POTENTIAL.
ELSEWHERE, UNSETTLED WEATHER WILL IMPACT THE PACIFIC NORTHWEST AND
THE NORTHERN ROCKIES AS MULTIPLE FRONTS AND SURGES OF PACIFIC
MOISTURE ARRIVE ACROSS THE TERRAIN GOING INTO EARLY NEXT WEEK.
MODERATE TO LOCALLY HEAVY RAIN IS EXPECTED FOR THE COASTAL RANGES
WITH HEAVY SNOW OVER THE HIGHER ELEVATIONS OF THE CASCADES,
NORTHERN SIERRA NEVADA, AND THE SAWTOOTH AND BITTERROOT RANGE OF
THE NORTHERN ROCKIES. THE HEAVIEST SNOWS SHOULD BE OVER THE
WASHINGTON CASCADES GOING THROUGH MONDAY WHERE 1 TO 2 FEET OF NEW
SNOW CAN BE EXPECTED.
TEMPERATURES WILL GENERALLY BE COOLER THAN NORMAL ACROSS THE
MID-ATLANTIC AND NORTHEAST FOR THE END OF THE WEEKEND AND EARLY
NEXT WEEK, BUT WILL BE MUCH WARMER THAN NORMAL ACROSS MUCH OF THE
CENTRAL AND NORTHERN U.S. OTHERWISE. NEAR NORMAL TEMPERATURES ARE
EXPECTED OVER MUCH OF THE WEST.
