DISCUSSION
KEY MESSAGE 1...A FAST-MOVING CLIPPER WILL BRING A PERIOD OF
ACCUMULATING LIGHT SNOW STARTING LATE THIS AFTERNOON THROUGH
LATE TONIGHT.
NOT MUCH CHANGE TO THE OVERALL FORECAST INTO TONIGHT. WAS REALLY
MORE LIKE FINE-TUNING BUT THE OVERALL MESSAGE IS UNCHANGED. A
FAST-MOVING CLIPPER BRINGS A MINOR SNOWFALL TO SOUTHERN NEW
ENGLAND. FOCUS OF THE HEAVIEST SNOWFALL IS EXPECTED ALONG THE
ROUTE 2 CORRIDOR. EXPANDED THE WINTER WEATHER ADVISORY.
WHILE MOST OF THE SNOWFALL SHOULD TRACK ACROSS NORTHERN NEW
ENGLAND, THERE IS A RISK OF SNOWFALL RATES OF 0.5-1.0" PER HOUR
BETWEEN 8 PM TO ABOUT 3 AM. THERE IS A POSSIBILITY SNOWFALL ENDS
A BRIEF PERIOD OF FREEZING RAIN AS THE DENDRITIC GROWTH ZONE
DRIES OUT. HOWEVER, DID NOT HAVE ENOUGH CONFIDENCE TO EXPAND
WINTER WEATHER ADVISORIES SOLELY FOR THE FREEZING RAIN RISK.
EXPECTING PRECIPITATION TO END FROM WEST TO EAST BETWEEN 2 AM TO
7 AM.
CLOSER TO THE SOUTH COAST, AN INTRUSION OF WARMER AIR SHOULD
INTRODUCE SOME PLAIN RAINFALL INTO THE FORECAST TONIGHT. NOT
EXPECTING MUCH SNOWFALL HERE AT ALL.
DRIER AND WARMER CONDITIONS EXPECTED WEDNESDAY INTO WEDNESDAY
NIGHT.
KEY MESSAGE 2...MOSTLY DRY THROUGH THE WEEKEND EXCEPT A FEW
CHANCES FOR LIGHT NUISANCE SNOW THURSDAY AND FRIDAY.
TEMPERATURES MAKE A RETURN TO NEAR NORMAL THROUGH THE WEEKEND.
ATTENTION TURNS TO THE LATE WEEKEND FOR A POTENTIAL COASTAL
STORM, BUT FORECAST CONFIDENCE REMAINS LOW DUE TO TRACK
UNCERTAINTY.
EXPECTING A FEW DAYS OF MOSTLY DRY WEATHER AFTER THE CLIPPER
SYSTEM MOVES THROUGH TONIGHT. WINDS RETURN TO PREDOMINATELY
NORTHWESTERLIES WEDNESDAY AND A SUBTLE INVERTED TROUGH SWINGS
THROUGH SOUTHERN NEW ENGLAND AS THE SURFACE LOW MOVES OFFSHORE.
THIS TROUGH COULD BRING ENOUGH FORCING TO PRODUCE A FEW LIGHT
SNOW SHOWERS ACROSS THE OUTER CAPE AND CAPE ANN WEDNESDAY NIGHT
INTO THURSDAY MORNING; HOWEVER, THE LATEST GUIDANCE HAS TRENDED
THOSE SNOW SHOWERS FURTHER EAST AND OFFSHORE. HREF PROBABILITES
ARE CURRENTLY SHOWING 10-15% CHANCE OF REACHING 0.1".
HIGH PRESSURE BEGINS TO BUILD IN OVER THE MIDWEST/MID-ATLANTIC
REGIONS THURSDAY. ONCE THE ARCTIC AIRMASS FINALLY GETS PUSHED
OFFSHORE, WE'LL SEE A RETURN TO MORE SEASONABLE TEMPERATURES. HIGH
TEMPERATURES MAKE IT INTO THE MID TO UPPER 30S OVER SOUTHERN NEW
ENGLAND STARTING WEDNESDAY, THOUGH OVERNIGHT LOWS WILL STILL FALL
INTO THE TEENS AND LOW 20S, WITH SOME SPOTS IN THE INTERIOR IN THE
SINGLE DIGITS.
ANOTHER UPPER-LEVEL LOW MOVES THROUGH FRIDAY NIGHT, BRINGING
CHANCES FOR ANOTHER QUICK SHOT OF SNOW SHOWERS TO SOUTHERN NEW
ENGLAND. NBM PROBABILITIES ONLY INDICATE 10-20% CHANCE OF 0.1"
ACROSS EASTERN MA AS PWATS REMAIN ONLY ABOUT 75% OF NORMAL.
HEADING INTO NEXT WEEK, GUIDANCE CONTINUES TO INDICATE POTENTIAL
IMPACTS FROM ANOTHER COASTAL STORM. CONFIDENCE REMAINS LOW AT THIS
POINT AS THE LATEST ENSEMBLE AND AI GUIDANCE HAVE A LARGE SPREAD IN
THE POTENTIAL TRACK OF THE LOW. ALTHOUGH, THE ENSEMBLES ARE SHOWING
THE LOWS THAT TRACK FURTHER WEST (CLOSER TO THE 40N/70W BENCHMARK)
STRENGTHENING MORE THAN THOSE THAT TRACK FURTHER EAST, SOMETHING WE
WILL CONTINUE TO BE MONITORING AS WE GET CLOSER TO THE WEEKEND.
