...HEAVY SNOW EXPECTED FOR PORTIONS OF THE NORTHEAST WITH BLIZZARD
CONDITIONS POSSIBLE FOR SOME AREAS...

...SNOW AND STRONG WINDS EXPECTED TODAY ACROSS PORTIONS OF THE
UPPER MIDWEST...

...HEAVY SNOW POSSIBLE ACROSS PORTIONS OF THE SOUTHERN AND CENTRAL
APPALACHIANS...

A STRONG AND IMPRESSIVE LOW PRESSURE SYSTEM WILL MOVE
NORTHEASTWARD OFF THE MID-ATLANTIC/NORTHEAST U.S. COASTLINE TODAY.
THE SYSTEM WILL SPREAD SNOW INTO PORTIONS OF SOUTHERN AND EASTERN
NEW ENGLAND TODAY, WITH THE POTENTIAL FOR HEAVY SNOW AT TIMES AS
FAR SOUTH AS LONG ISLAND. SNOWFALL AMOUNTS OF 5 TO 10 INCHES ARE
EXPECTED FROM THE EASTERN HALF OF LONG ISLAND NORTHWARD ACROSS
SOUTHEASTERN NEW ENGLAND. THE HEAVIEST SNOW IS EXPECTED ACROSS
EASTERN MASSACHUSETTS INCLUDING CAPE COD, WHERE 8 TO 12 INCHES OF
SNOW ARE POSSIBLE, WITH LOCALIZED AMOUNTS EXCEEDING 15 INCHES.
ADDITIONALLY, THE INTENSITY OF THE LOW PRESSURE SYSTEM OFFSHORE
WILL RESULT IN WINDS OF 30 TO 40 MPH WITH GUSTS AS HIGH AS 65 MPH
PORTIONS OF SOUTHEAST MASSACHUSETTS INCLUDING CAPE COD AND THE
ISLANDS. STRONG WINDS AND HEAVY SNOW WILL CREATE BLIZZARD
CONDITIONS AT TIMES. HEAVY WET SNOW AND STRONG WINDS MAY RESULT IN
DOWNED TREE LIMBS AND POSSIBLE POWER OUTAGES. THIS LOW PRESSURE
SYSTEM WILL MOVE AWAY FROM NEW ENGLAND MONDAY NIGHT INTO EARLY
TUESDAY MORNING -- AND THE SNOW AND WIND WILL LESSEN IN INTENSITY
OR TAPER OFF.

A COMPLEX LOW PRESSURE SYSTEM WILL MOVE ACROSS THE GREAT LAKES
TODAY. THE SYSTEM WILL PRODUCE GENERALLY LIGHT SNOW ACROSS
PORTIONS OF THE UPPER MIDWEST TODAY, WHICH WILL COMBINE WITH
STRONG WINDS GUSTING IN EXCESS OF 50 MPH IN SOME AREAS TO PRODUCE
BLIZZARD CONDITIONS. SNOW AND WIND SHOULD TAPER OFF ACROSS THE
UPPER MIDWEST BY THIS EVENING AS THE SYSTEM MOVES EAST. THE SYSTEM
WILL ALSO PRODUCE SCATTERED AREAS OF SNOW ACROSS THE GREAT LAKES
AND OHIO VALLEY TODAY INTO TUESDAY. ACCUMULATIONS WILL GENERALLY
BE LIGHT, WITH THE EXCEPTION OF AREAS RECEIVING LAKE EFFECT
ENHANCEMENT. BY THIS EVENING, THE SYSTEM WILL TRANSFER ENERGY TO A
NEW LOW PRESSURE SYSTEM DEVELOPING ACROSS THE SOUTHERN
MID-ATLANTIC STATES. THIS SYSTEM WILL SPREAD PRECIPITATION ACROSS
THE APPALACHIANS AND MID-ATLANTIC, WHICH WILL START AS A MIX OF
RAIN AND SNOW FOR MANY AREAS, BUT WILL CHANGE TO SNOW AS COLDER
AIR WRAPS INTO THE NEWLY DEVELOPING SYSTEM. AS THIS LOW PRESSURE
SYSTEM MOVES OFFSHORE TUESDAY MORNING, UPPER-LEVEL ENERGY WILL
LINGER OVER THE GREAT LAKES, APPALACHIANS, AND MID-ATLANTIC, WHICH
WILL KEEP AREAS OF SNOW POSSIBLE THROUGH TUESDAY NIGHT FOR MANY
AREAS. HEAVY SNOW WILL BE POSSIBLE FOR PORTIONS OF THE CENTRAL AND
SOUTHERN APPALACHIANS, AS WELL AS PORTIONS OF THE MID-ATLANTIC
REGION IN ASSOCIATION WITH THIS SYSTEM. THE SYSTEM WILL ALSO BRING
ANOTHER ROUND OF SNOWFALL TO SOUTHERN NEW ENGLAND, ALBEIT
RELATIVELY LIGHT COMPARED TO THE SYSTEM AFFECTING THE REGION TODAY.

IN THE WAKE OF THIS SECOND LOW PRESSURE SYSTEM, MUCH OF THE
EASTERN HALF OF THE NATION WILL BECOME COLDER AS AN ARCTIC AIR
MASS MOVES IN. HIGH TEMPERATURES ON TUESDAY AND WEDNESDAY ARE
FORECAST TO BE 10 TO 25 DEGREES BELOW AVERAGE ACROSS MUCH OF THE
MIDWEST, OHIO VALLEY, AND SOUTHEAST. MEANWHILE, THE WEST WILL
EXPERIENCE DRY CONDITIONS WITH GENERALLY ABOVE AVERAGE
TEMPERATURES THROUGH WEDNESDAY AS HIGH PRESSURE REMAINS IN PLACE.
