...STRONG NOR'EASTER TO IMPACT PORTIONS OF THE NORTHERN
MID-ATLANTIC AND SOUTHERN NEW ENGLAND TODAY WITH AREAS OF HEAVY
SNOW, STRONG WINDS, AND COASTAL FLOODING...
...NEW STORM SYSTEM TO ARRIVE ACROSS THE NORTHWEST OVER THE NEXT
COUPLE OF DAYS WHICH WILL BRING LOCALLY HEAVY RAIN AND MOUNTAIN
SNOWFALL...
A STRONG NOR'EASTER WILL BE RAPIDLY PUSHING EAST AND AWAY FROM THE
MID-ATLANTIC COAST THIS MORNING AND WELL OUT TO SEA BY LATER
TODAY. THE STORM WILL CONTINUE TO RAPIDLY DEEPEN AND WILL PROMOTE
AREAS OF SNOW, OR RAIN CHANGING TO SNOW EARLY THIS MORNING ACROSS
SOUTH-CENTRAL TO EASTERN PENNSYLVANIA, CENTRAL AND NORTHERN NEW
JERSEY, AND SOUTHERN NEW ENGLAND. THE AXIS OF HEAVIEST SNOWFALL IS
EXPECTED FROM EASTERN PENNSYLVANIA, INCLUDING THE LEHIGH VALLEY,
THROUGH NORTHERN NEW JERSEY, FAR SOUTHEAST NEW YORK, AND SOUTHERN
NEW ENGLAND. THIS WILL INCLUDE THE GREATER NEW YORK CITY
METROPOLITAN AREA. SOME AREAS ESPECIALLY OVER SOUTHERN NEW ENGLAND
ARE EXPECTED TO SEE AS MUCH AS 6 TO 12 INCHES OF SNOW, WITH LESSER
AMOUNTS OF 3 TO 6 INCHES ELSEWHERE, AND THIS HEAVY SNOW IS
EXPECTED TO PRODUCE LOCALLY SIGNIFICANT TRAVEL DISRUPTIONS. STRONG
WINDS ARE EXPECTED ON THE BACK SIDE OF THE DEPARTING LOW CENTER,
AND THIS COUPLED WITH THE HEAVY, WET SNOW MAY RESULT IN DOWNED
TREES AND POWER LINES WHICH WILL RESULT IN CONCERNS FOR POWER
OUTAGES. SOME COASTAL FLOODING WILL ALSO BE POSSIBLE TODAY DURING
HIGH TIDE ALONG THE NORTHERN MID-ATLANTIC AND SOUTHERN NEW ENGLAND
COASTS.
MEANWHILE, THERE WILL BE A WEAK STORM SYSTEM CROSSING THE CENTRAL
PLAINS, MIDWEST, AND GREAT LAKES REGION ON WEDNESDAY AND THURSDAY.
DESPITE THE RELATIVE LACK OF COLD AIR FOR THIS SYSTEM TO WORK
WITH, THERE WILL BE A SWATH OF LOCALLY A FEW INCHES OF SNOW, WITH
SOME RAIN CLOSER TO THE TRACK OF THE LOW PRESSURE CENTER.
A NEW STORM SYSTEM WILL ALSO BE ARRIVING IN FROM THE PACIFIC OCEAN
FOR WEDNESDAY AND THURSDAY WHICH WILL BRING IN A NEW SURGE OF
MOISTURE AND AREAS OF LOCALLY HEAVY PRECIPITATION. THIS WILL
INCLUDE HEAVY RAINFALL FOR THE COASTAL RANGES OF THE PACIFIC
NORTHWEST AND DOWN INTO NORTHERN CALIFORNIA. LOCALLY A COUPLE
INCHES OF RAIN CAN BE EXPECTED. FARTHER INLAND OVER THE HIGHER
TERRAIN OF THE CASCADES, SIERRA NEVADA, AND GRADUALLY THE NORTHERN
ROCKIES, THIS PRECIPITATION WILL FALL AS HEAVY SNOW. AS MUCH AS 1
TO 2 FEET OF NEW SNOW WITH ISOLATED HEAVIER AMOUNTS CAN BE
EXPECTED GOING THROUGH THURSDAY.
THE REMAINDER OF THE COUNTRY GOING THROUGH THE MIDDLE OF THE WEEK
WILL BE RATHER DRY AND TRANQUIL. TEMPERATURES FOR LARGE AREAS OF
THE MIDWEST WILL CONTINUE TO BE ABOVE NORMAL, WITH TEMPERATURES
SOMEWHAT BELOW NORMAL FOR THE NORTHEAST AND INTERMOUNTAIN WEST.
THERE WILL BE THE BEGINNING OF A SURGE OF AT LEAST MODIFIED ARCTIC
AIR FROM CANADA BY LATE WEDNESDAY AND THURSDAY INTO THE NORTHERN
HIGH PLAINS, AND THIS WILL SET THE STAGE FOR EVEN COLDER
TEMPERATURES ANOMALIES ARRIVING BY THE LATTER PART OF THE WEEK.
