THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHERN CONNECTICUT...ALL OF
MASSACHUSETTS EXCEPT BERKSHIRE COUNTY...AND RHODE ISLAND.
.DAY ONE...TODAY AND TONIGHT.
HAZARDOUS WEATHER IS NOT EXPECTED AT THIS TIME.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
A COASTAL STORM WILL IMPACT THE REGION SATURDAY INTO SATURDAY
NIGHT...BUT THE RAIN/SNOW LINE AND NORTHWEST EXTENT OF HEAVY
PRECIPITATION REMAINS UNCERTAIN.
THE GREATEST THREAT FOR A NARROW BAND OF HEAVY WET SNOW APPEARS
TO BE NORTHWEST OF THE I-95 CORRIDOR INTO THE WORCESTER HILLS AND
EASTERN CONNECTICUT. TO THE SOUTHEAST OF I-95 IT WILL PROBABLY BE
TOO WARM FOR SIGNIFICANT SNOW AND PORTIONS OF WESTERN
MASSACHUSETTS MAY BE REMOVED FROM THE HEAVIEST PRECIPITATION.
TRACK NOT SET IN STONE...SO THE RISK FOR THIS NARROW BAND OF HEAVY
WET SNOW MAY SHIFT EAST OF WEST. "IF" HEAVY WET SNOW DOES COME TO
FRUITION FOR A PORTION OF THE REGION...THERE WOULD BE THE RISK FOR
SOME DOWNED TREE LIMBS/ISOLATED POWER OUTAGES.
A WIND ADVISORY MAY BE NEEDED FOR THE CAPE AND ISLANDS SATURDAY
NIGHT.
FINALLY...MINOR COASTAL FLOODING IS POSSIBLE DURING THE VERY
EARLY SUNDAY MORNING HIGH TIDE ALONG THE EASTERN MA COAST BUT
SIGNIFICANT COASTAL FLOODING IS NOT EXPECTED.
