SEEN TODAY. HOWEVER, HIGHS WILL ONLY BE IN THE SINGLE DIGITS ACROSS
THE NORTH, AND IN THE LOWER TO MID TEENS SOUTH.

ENGLAND COAST TUESDAY WHILE OCCLUDING AND BEING CAPTURED BENEATH
THE UPPER LOW. DEFORMATION ZONE SNOWS...HEAVY AT TIMES...WILL LIFT
ACROSS THE REGION TUESDAY. STRONG WINDS WILL ALSO OCCUR TUESDAY
PRODUCING AREAS OF BLOWING SNOW. BASED ON EXPECTED WIND GUSTS OF
40 TO 50 MPH DOWNEAST...WITH HIGHER GUSTS POSSIBLE ALONG THE

A WEAK RIDGE OF HIGH PRESSURE WILL BRING MOSTLY CLEAR SKIES AND

THROUGH FRIDAY. THE ECMWF IS SHOWING THE HIGHEST AMOUNTS WITH UP TO
A FOOT POSSIBLE IN CENTRAL AND SOUTHERN AREAS WITH THE GFS SHOWING
MORE MODEST AMOUNTS OF 6-8 INCHES IN MOST PLACES. RIGHT NOW IT LOOKS
LIKE IT WILL BE COLD ENOUGH FOR ALL SNOW ACROSS THE AREA WITH THE
EXCEPTION OF THE COAST WHICH MAY GET SOME RAIN OR SLEET MIXING IN
DURING THE HEIGHT OF THE STORM MIDDAY FRIDAY. THE STORM IS EXPECTED
TO INTENSIFY AS IT TRACKS NORTHEAST THROUGH THE BAY OF FUNDY. THIS
MEANS THE WINDIEST CONDITIONS FROM THIS SYSTEM COULD BE FROM NORTH
AND NORTHWEST WINDS ON THE WESTERN SIDE OF THE LOW FRIDAY INTO
FRIDAY NIGHT WHEN BLOWING AND DRIFTING WILL BE LIKELY. SNOW WILL
TAPER OFF FRIDAY NIGHT AND DRY AND COLD WEATHER WILL RETURN FOR THE
WEEKEND.

THE UPCOMING SYSTEM; THIS IS WHAT WE WANT PEOPLE TO FOCUS ON.
