&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...

*** THUNDERSTORMS SLOWLY WEAKENING THIS EVENING ACROSS WESTERN MA
 AND CT ***

930 PM UPDATE...

CONVECTION ACROSS WESTERN MA AND NORTHWEST CT BEGINNING TO WEAKEN
AS BOUNDARY LAYER COOLS AND T-STORMS MOVE INTO A MORE STABLE
ENVIRONMENT ACROSS EASTERN MA/RI AND CENTRAL-EASTERN MA. THUS
TREND OVER THE NEXT FEW HOURS WILL BE FOR CONVECTION TO WEAKEN.
MAIN THREATS WITH STORMS WILL BE GUSTY WINDS/SMALL HAIL AND HEAVY
RAINFALL.

SHOWERS WITH EMBEDDED THUNDER MAY SURVIVE INTO EASTERN CT/RI AND
SOUTHEAST MA LATER THIS EVENING...AS APPROACHING SHORT WAVE RESULTS
IN HEIGHT FALLS/STEEPENING MID LEVEL LAPSE RATES AND MODEST
FORCING FOR ASCENT. 12Z ARW AND NMM CAPTURING THIS WELL AND
VERIFYING NICELY AT 00Z.

WITH SUNSET BLYR COOLING AS RESULTED IN STRATUS AND FOG
REDEVELOPING OVER RI AND SOUTHEAST MA. THIS WILL CONTINUE UNTIL
ABOUT 06Z OR SO...THEN COLD FRONT WILL SWEEP ACROSS THIS REGION
SCOURING OUT LOW LEVEL MOISTURE WITH GUSTY WNW WINDS BEHIND THE
FRONT.

PREVIOUS DISCUSSION...

MUCH DRIER AND COOLER AIR WORKS INTO THE REGION BEHIND THE COLD
FRONT AFTER MIDNIGHT.  LOW TEMPS BY DAYBREAK WILL BE DOWN INTO THE
UPPER 40S TO THE MIDDLE 50S.  LEFT OVER LOW CLOUDS/FOG PATCHES WILL
SCOUR OUT TOWARD DAYBREAK ACROSS THE FAR SOUTHEAST NEW ENGLAND
COAST.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
WEDNESDAY...

MUCH DRIER AIR CONTINUES WILL WORK INTO SOUTHERN NEW ENGLAND BEHIND
THE COLD FRONT.  PARTLY SUNNY SKIES ARE EXPECTED BUT THERE WILL BE
SOME SCATTERED DIURNAL CUMULUS CLOUDS ESPECIALLY ACROSS OUR NORTHERN
ZONES.  850 MB TEMPS DROP TO BETWEEN 0C AND +4C BY 18Z...BUT THERE
WILL BE DEEP MIXING.  THEREFORE...EXPECT HIGHS TO REACH WELL INTO
THE 60S...WITH PERHAPS A FEW LOCATIONS TOUCHING 70 ACROSS RHODE
ISLAND/SOUTHEAST MA.  IT WILL BE BLUSTERY AS GOOD MIXING WILL RESULT
IN A FEW HOURS OF NORTHWEST WIND GUSTS OF 25 TO 30 MPH DURING THE
AFTERNOON.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
*/ HIGHLIGHTS...

 - SEASONABLE AND DRY UNDER HIGH PRESSURE THURSDAY
 - SWEEPING COLD FRONT FRIDAY
 - RETURN OF DRY AND COOLER CONDITIONS FOR THE WEEKEND
 - PERHAPS A RETURN OF WET-WEATHER EARLY NEXT WEEK

OVERVIEW AND MODEL PREFERENCES...
WITH 19.12Z MODEL GUIDANCE CONTINUING TO SHOW REASONABLY GOOD
AGREEMENT THROUGH THE LONG TERM...A BLEND OF OPERATIONAL GUIDANCE
AND PERSISTENCE WILL BE USED AS A BASELINE. THERE ARE A FEW TWEAKS
TO MAKE. THE LONGWAVE TROF THAT SETTLES ACROSS ERN CANADA AND THE
NE CONUS WILL ALLOW FOR A FAIRLY COLD AIRMASS TO ADVECT ACROSS THE
REGION WITH A STRONG VORTEX MOVING THROUGH ON FRI...MANIFESTING AS
A COLD FRONT. MODEL DWPTS ARE LIKELY TOO HIGH HERE. WHICH MEANS
THAT SHOULD THE PRES GRADIENT SLACKEN ENOUGH BOTH FRI AND SAT
NIGHTS...MAY NEED TO MONITOR FOR A PERIOD WHERE FROST IS POSSIBLE.
ALSO...AS NOTED BY PREVIOUS FORECASTER...THIS DRY AIR WOULD ALSO
SUGGEST HIGHER FIRE WEATHER POTENTIAL DEPENDENT ON RAINFALL
TODAY/THIS EVENING.

DETAILS...

WED NIGHT INTO THU NIGHT...
MAINLY DRY WX EXPECTED AS HIGH PRES MOVES ACROSS THE REGION. WILL
LIKELY SEE SOME PERSISTENT CLOUD COVER AT TIMES THOUGH...GIVEN
UPPER LVL CYCLONIC CURVATURE AND MODEST MID LVL MOISTURE. +3C TO
+5C H85 TEMPS SHOULD STILL BE REACHED...IF NOT EVEN SLIGHTLY
HIGHER. THEREFORE...SUSPECT MAX/MIN VALUES NEAR SEASONAL NORMALS.

FRI...
FAIRLY ROBUST ARCTIC INFLUENCED VORTEX WILL BE MOVING THROUGH THE
BASE OF THE LONGWAVE TROF ACROSS THE NE CONUS AND ERN CANADA. THE
SFC REFLECTION IS ITSELF A STRONG COLD FRONT WITH DECENT
BAROCLINIC PACKING EVIDENT. THEREFORE...PLENTY OF POTENTIAL FOR
LIFT WITH THIS FEATURE AS IT MOVES ACROSS THE REGION FRI. THE
LIMITING FACTOR IS MOISTURE AS PREVIOUS LONG TERM FORECASTER
NOTED. PWATS REALLY ONLY TOP OUT AROUND 0.60 INCHES. BY THE
AFTERNOON. STILL FEEL THE SLIGHT CHANCE POPS ADVERTISED ARE
WARRANTED...ESPECIALLY JUST GIVEN HOW HIGH THE LIFT POTENTIAL IS
WITH THE FRONT ITSELF. THERE IS A LITTLE BIT OF LOW LVL
INSTABILITY INVOF THE BL TO WORK WITH AS WELL. THEREFORE...WILL
MAINTAIN PRECIP CHANCES AS THEY STAND FOR THE TIME BEING.

FRI NIGHT INTO SAT...
AS MENTIONED ABOVE THE KEY FOR THIS TIME PERIOD IS THE
POTENTIALLY DRY AND COOL AIRMASS WHICH IS PROGGED TO SETTLE ACROSS
THE REGION. IN FACT 1000-500 THICKNESS VALUES ARE SUB 540DAM FOR
MUCH OF THE REGION. WITH H85 TEMPS DIPPING BELOW 0C FOR SAT.
THEREFORE...WILL NEED TO MONITOR FOR LOW DWPTS AND RH VALUES BY
DAY...AND POTENTIALLY NEAR FREEZING TEMPERATURES FOR COLDER
VALLEYS AT NIGHT. CONFIDENCE IS NOT HIGH ENOUGH TO ALARM ON FROST
POTENTIAL AT THIS POINT GIVEN THERE IS SOME QUESTION IN THE PRES
GRADIENT AND WINDS REMAINING ELEVATED...BUT FEEL IT IS AT LEAST
WORTH MENTIONING/MONITORING.

EARLY NEXT WEEK...
SUBTROPICAL RIDGING WILL ONCE AGAIN BE GAINING STRENGTH THROUGH
THE PERIOD...ALLOWING FOR A WARMING OF THE COLUMN ACROSS THE NE
THROUGH THE PERIOD. ASIDE FROM THE WARMING...INDICATIONS OF A WARM
FRONTAL PASSAGE WITH POTENTIAL FOR PRECIP/CONVECTION INDICATED FOR
TUES. SOMETHING TO KEEP AN EYE ON.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

SHORT TERM /THROUGH WEDNESDAY/...

930 PM UPDATE...

ACTIVITY ENTERS EASTERN CT/RI AND SOUTHEAST MA. A FEW OF THE
STRONGER STORMS MAY PRODUCE GUSTY WINDS...SMALL HAIL AND HEAVY
RAIN THRU 1030 PM. OTHERWISE WEAKENING TREND CONTINUES WITH JUST
SHOWERS ENTERING RI AND SOUTHEAST MA. IFR CONDITIONS IN LOW CLOUDS

AREAS OF FOG ACROSS OUR SOUTHERN WATERS FOR THE FIRST PART OF THE
NIGHT...SOME OF WHICH MAY BE LOCALLY DENSE.  OTHERWISE...SOUTHWEST
WINDS AT 10 TO 15 KNOTS WILL SHIFT TO THE NORTHWEST AFTER MIDNIGHT
BEHIND A STRONG COLD FRONT.  SOME GUSTS INTO THE LOWER 20 KNOTS ARE
EXPECTED WITH PRESSURE RISES BEHIND THE FRONT.

25 KNOTS EXPECTED NEAR SHORE WITH DEEP MIXING OVER THE LAND.  HAVE
