.SYNOPSIS...
A RIDGE OF HIGH PRESSURE ASSOCIATED WITH VERY COLD AIR FROM
CANADA WILL BUILD ACROSS OUR REGION TONIGHT BRINGING THE
POSSIBILITY OF FROST LATE TONIGHT INTO MONDAY MORNING...BEFORE YET
ANOTHER DISTURBANCE TRACKS ACROSS THE REGION LATE MONDAY INTO
MONDAY NIGHT BRINGING A FEW MORE SHOWERS. WEAK HIGH PRESSURE
BUILDS BACK IN FOR TUESDAY...WITH SLIGHTLY WARMER TEMPERATURES.
&&
.NEAR TERM /THROUGH MONDAY NIGHT/...
FOR TONIGHT EXPECT A VERY COLD AIRMASS TO SET UP ACROSS FA IN THE
WAKE OF THE FRONT WHICH MOVED THROUGH THE REGION DURING THE LATE
MORNING AND AFTERNOON HOURS AND WITH SKIES CLEARING OVERNIGHT TEMPS
WILL DROP INTO THE UPPER 20S TO AROUND 40 WITH THE LOWEST READINGS
IN THE SOUTHERN ADIRONDACKS AND SOUTHERN GREEN MOUNTAINS. AT THIS
TIME IT APPEARS THAT THE ONLY AREAS WHERE FROST NOT A THREAT ARE
THE EASTERN MOHAWK VALLEY...HELDERBERGS...GREATER CAPITAL
DISTRICT...MID HUDSON VALLEY...SOUTHERN TACONICS AND LITCHFIELD
HILLS...ALTHOUGH TEMPS IN THESE AREAS WILL DROP INTO THE UPPER 30S.
PLEASE REFER TO FREEZE WARNINGS AND FROST ADVISORIES...ALBNPWALY
FOR FURTHER DETAILS. GFS HAS H8 TEMPS BOTTOMING OUT AT 06Z SUN AT
+3 TO -2 C WITH NAM HAVING H8 TEMPS BOTTOMING OUT AT 06Z BETWEEN
+4 AND -3 C. BOTH MODELS ALSO SHOW SIGNIFICANT WARMING OF 2-3 C IN
BOUNDARY LAYERS BTWN 06Z AND 12Z. SOME OTHER FACTORS WHICH ARE NOT
IDEAL FOR TEMPS GETTING EVEN COLDER ARE PRESSURE GRADIENT THAT
WILL BE IN PLACE THROUGH AT LEAST MIDNIGHT AND SATURATED GROUND
FROM RECENT RAINS WHICH MAY PRODUCE FOG. WILL INCLUDE AREAS OF FOG
IN ZONES WHERE FROST NOT EXPECTED.
ANOTHER FAST MOVING SYSTEM WILL IMPACT OUR REGION LATE MONDAY
INTO MON NIGHT. DISCREPANCIES EXIST IN TIMING AND PLACEMENT OF
PCPN AMONGST GFS...NAM AND ECMWF WITH GFS HAVING BEST CHANCE OF
PCPN ACRS MUCH OF AREA MON NGHT...WHILE NAM HAS MOISTURE DRYING UP
AS IT ADVANCES EAST AND ECMWF HAS A SOLUTION WHICH IS BASICALLY IN
THE MIDDLE. WILL GO WITH A SLIGHT CHANCE TO CHANCE OF SHOWERS
MONDAY AFTERNOON ACROSS NORTHERN HALF OF FA AND THEN A CHANCE OF
SHOWERS ACROSS ENTIRE FA MONDAY NIGHT. BEST CHANCE STILL APPEARS
TO BE ACRS NRN PORTION OF FA CLOSER TO BETTER DYNAMICS. FOR TEMPS
HAVE HIGHS ON MON IN THE UPPER 50S TO LOWER 70S AND LOWS ON MON
NGHT IN THE LOWER 40S TO LOWER 50S.
&&
.SHORT TERM /TUESDAY THROUGH TUESDAY NIGHT/...
HIGH PRESSURE BUILDS IN DURING THE DAY ON TUESDAY BEFORE YET
ANOTHER CLIPPER TYPE SYSTEM MOVES INTO OUR AREA LATE TUESDAY
NIGHT. WILL KEEP TUESDAY DRY WITH A SLIGHT MODERATING TREND IN
TEMPS AS TEMPS EXPECTED TO BE A FEW DEGREES WARMER THAN MONDAY
WITH HIGHS IN THE MID 60S TO MID 70S IN MOST AREAS. ON TUESDAY
NIGHT HAVE SLIGHT CHANCE TO CHANCE POPS AFTER MIDNIGHT WITH LOWS
IN THE UPPER 30S TO LOWER 50S.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
GUIDANCE STILL INDICATE BROAD TROUGH OVER EASTERN NORTH
AMERICA...GENERATING MULTIPLE WAVES WITH PERIODS OF CLOUDS AND
SHOWERS FOR THE MIDDLE OF NEXT WEEK THROUGH THE WEEKEND. THIS WILL
ALSO RESULT IN BELOW NORMAL TEMPERATURES.
WEDNESDAY STARTS WITH A SFC LOW OVER PENNSYLVANIA TRACKING EASTWARD
WITH CHC POPS THROUGH WEDNESDAY NIGHT. RAIN SHOWERS EXPECTED TO
AFFECT THE ENTIRE CWA...BUT SOUTHERN HALF OF FA WILL HAVE SLGT CHC
OF TS WITH BEST CAPE VALUES GREATER THAN 1500JOULES IN THE MID TO
LOWER HUDSON VALLEY.
BOTH GFS AND ECMWF SHOW HIGH PRESSURE WILL BUILD IN OVER THE AREA
FOR THURSDAY AND MOST OF FRIDAY. MORE UNSETTLED WEATHER ON FRIDAY
NIGHT INTO SATURDAY...ONE WAVE WILL APPROACH FROM CANADA WHILE
ANOTHER UPPER LEVEL WAVE TRACKS NORTHWARD FROM THE SOUTHEASTERN U.S.
HOWEVER...DIFFERENCE IN MODELS WITH REFERENCE TO THE TRACK AND
TIMING STILL APPARENT. HAVE KEPT POPS AROUND 25-40 THROUGH SATURDAY
NIGHT BEFORE ANOTHER IMPULSE APPROACHES FROM THE CENTRAL U.S. FOR
SUNDAY.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
EXPECT VFR CONDITIONS THROUGH 00Z/TUE AT ALL TAF SITES. THERE IS A
SLIGHT CHC FOR SOME PATCHY GROUND FOG TO DEVELOP BETWEEN 08Z-11Z/MON
AT KGFL...BUT CONFIDENCE AT THIS STAGE TOO LOW TO INCLUDE MENTION IN
TAF...ESP GIVEN THE POSSIBILITY FOR WINDS TO PERSIST...AS WELL AS
THE INITIALLY DRY AIR MASS IN PLACE.
HIGH/MID LEVEL CLOUDS WILL GRADUALLY INCREASE ACROSS NORTHERN TAF
SITES MON MORNING...AND WILL PERSIST INTO THE AFTERNOON. GIVEN THE
APPROACH OF ANOTHER WEAK COLD FRONT FROM THE NW...THERE IS THE
REMOTE POSSIBILITY OF ISOLATED SHOWERS/SPRINKLES TO DEVELOP
TOWARD...OR JUST AFTER 00Z/TUE...WITH BEST CHC TO THE N AND W.
AGAIN...OVERALL PROBABILITY TOO LOW TO INCLUDE ANY MENTION AT THIS
TIME...AND CONDITIONS SHOULD REMAIN VFR EVEN WITHIN ANY POTENTIAL
LIGHT SHOWERS/SPRINKLES.
WINDS WILL REMAIN GUSTY OVER THE NEXT 1-3 HOURS...WITH SUSTAINED
SPEEDS OF 12-17 KT FROM THE W TO NW...AND GUSTS OF 20-30 KT
POSSIBLE. THEREAFTER...WE EXPECT THE GUSTS TO SUBSIDE...WITH WEST TO
NW WINDS OF 8-12 KT. THE WINDS WILL THEN DECREASE FURTHER AFTER
06Z/MON...ESP AT KGFL AND KPOU...WHERE THEY MAY BECOME LIGHT AND
VARIABLE. WINDS WILL THEN BECOME W AND SW DURING MONDAY...GENERALLY
AT 10-15 KT BY MID AFTERNOON.
