INTO THE CANADIAN MARITIMES. OUTSIDE OF A FEW CIRRUS CLOUDS
DRIFTING SOUTHWEST TO NORTHEAST ACROSS THE CWA...CONDITIONS WILL
BE MAINLY CLEAR AND DRY...AND SLIGHTLY WARMER THAN LAST NIGHT AS
SOUTHERLY FLOW INCREASES BETWEEN THE DEPARTING HIGH AND AN

NICELY FROM BELOW 0C IN THE MORNING TO +3-5C BY THE AFTERNOON
SUPPORTING HIGHS NEAR NORMAL IN THE 50S VALLEYS...TO MID/UPPER
40S ELSEWHERE. FRONT APPROACHES THE ST. LAWRENCE VALLEY LATE IN
THE DAY WITH A FEW RAIN SHOWERS MOVING IN BY SUNSET. DUE TO THE
DRY ANTECEDENT SURFACE CONDITIONS...ALONG WITH WEAK LIFT AND A
VERY THIN RIBBON OF 1000-700MB MOISTURE ASSOCIATED WITH THE
FRONT...NOT EXPECTED MORE THAN A TENTH OF QPF AREA-WIDE WITH THE
FRONTAL PASSAGE. AS IT DOES SHIFT ACROSS THE AREA FRIDAY NIGHT
THOUGH...MEAN BL TEMPS DO SUPPORT A TRANSITION TO SOME SNOW
SHOWERS ACROSS THE HIGHER TERRAIN OF THE DACKS AND NE VT...BUT
SHOULD ONLY AMOUNT TO A DUSTING TO AROUND AN INCH.

FRONT CLEARS THE AREA TO THE EAST SATURDAY MORNING WITH LINGERING
PRECIP ACROSS NE VT ENDING BY MID-DAY. 850-925MB TEMPS CRASH BACK
