DISCUSSION
KEY MESSAGE 1...
A WARM FRONT CONTINUES TO APPROACH FROM PA AND THE MID ATLANTIC
REGION THIS MORNING, AS A PREFRONTAL SFC TROUGH CONTINUES TO
BRING SOME SHOWERS TO THE ADIRONDACKS AND SOUTHERN VT. THE MID
AND UPPER LEVEL FLOW CONTINUES TO BE NEARLY ZONAL. IN THE WARM
ADVECTION PATTERN, SOUTH TO SOUTHEAST WINDS HAVE INCREASED WITH
SOME GUSTS 25 TO 35 MPH IN THE CAPITAL REGION AND OVER THE
NORTHERN TACONICS. A SOUTHWESTERLY LOW-LEVEL JET AT 850 HPA OF
40-55 KT WILL IMPACT THE REGION TODAY FOCUSING ANOTHER ROUND OF
SHOWERS WITH THE WARM FRONT AND A PREFRONTAL SFC TROUGH. LITTLE
TO NO INSTABILITY IS PRESENT, SO THUNDER WAS LEFT OUT OF THE
FORECAST. THE SOUTH TO SOUTHWEST WINDS WILL INCREASE TO 15-25
MPH IN THE IMMEDIATE CAPITAL REGION, PORTIONS OF THE HUDSON
RIVER VALLEY, THE NORTH CENTRAL TACONICS, EASTERN CATSKILLS, AND
THE BERKSHIRES AND N-S ORIENTED VALLEYS WITH SOME GUSTS 30-40
MPH. WE LEANED CLOSER TO THE LATEST NBM 90% WIND/WIND GUSTS FOR
LATE THIS MORNING THROUGH THE AFTERNOON. THE PEAK GUSTS WILL
LIKELY BE IN THE EARLY TO MID PM WITH THE TROUGH PASSAGE. THE
HIGHEST POPS IN THE 50-90% RANGE WILL BE NORTH AND WEST OF THE
TRI CITIES. HIGHS TODAY WITH MOSTLY CLOUDY CONDITIONS WILL BE
MILD WITH MID 50S TO MID 60S OVER THE HIGHER TERRAIN, AND MID
60S TO MID 70S IN THE VALLEYS. SHOWERS DIMINISH TONIGHT WITH
SOME PATCHY FOG DEVELOPING IN THE SOUTHERN DACKS AND UPPER
HUDSON VALLEY. LOWS WILL BE VERY MILD IN THE 50S WITH SOME
MID/UPPER 40S OVER THE ADIRONDACK PARK AND SOUTHERN GREENS.
KEY MESSAGE 2...
ON TUESDAY, THE FLOW CONTINUES TO BE ZONAL ACROSS THE GREAT
LAKES REGION INTO THE NORTHEAST WITH STRONG RIDGING OVER THE
SOUTHEAST AND GULF REGION. H850 TEMPS WILL BE RUNNING 1 TO 2
STDEVS ABOVE NORMAL, AS MAX TEMPS ON TUE WILL GENERALLY BE 15-20
DEGREES ABOVE NORMAL WITH 60S AND 70S WITH A FEW LOWER 80S NEAR
I-84. THE MAIN FRONTAL BOUNDARY WILL BE NEAR NORTHERN NY AND
THE CANADIAN BORDER. A PREFRONTAL SFC TROUGH AND WEAK WAVE
MOVING ALONG THE BOUNDARY WILL BRING SOME LATE MORNING/AFTERNOON
SHOWERS AND THUNDERSTORMS. THE TIMING IS VARIABLE ON THE CAMS,
BUT SOME OF THE STORMS COULD BE TALL ENOUGH FOR STRONG/ISOLATED
DAMAGING WIND GUSTS. THE LATEST HREFS FORECASTS MEAN SBCAPES
500-1000 J/KG WITH 0-6 KM DEEP SHEAR 40-50 KT. MID LEVEL LAPSE
RATES WILL BE STEEP WITH SOME OF THE MODEL SOUNDING SHOWING
STEEP LOW-LEVEL LAPSE RATES. SFC DEWPOINTS WILL BE IN THE 50S TO
LOWER 60S. A CLUSTER OF THUNDERSTORMS MAY IMPACT THE REGION
WITH SOME ISOLATED DAMAGING WIND GUSTS. SPC HAS UPGRADED MOST OF
THE REGION INTO A LEVEL 1 MARGINAL RISK. THE 3-KM NAM HAS A BIT
MORE INSTABILITY WITH MLCAPES AROUND 1000 J/KG. SOME STRONG TO
POTENTIALLY SEVERE T-STORMS LOOK POSSIBLE TUE PM INTO THE EARLY
EVENING. ZONAL FLOW IS CHALLENGING TO TIME THESE DISTURBANCES.
WE KEPT OUR HIGHEST POPS FOR SHOWERS (60-90%) AND A CHANCE OF
T-STORMS FROM THE CAPITAL REGION NORTH AND WEST. THE
SHOWER/T-STORM ACTIVITY DIMINISHES PRIOR TO MIDNIGHT WITH
ANOTHER VERY MILD NIGHT WITH LOWS IN THE 50S TO LOWER 60S.
KEY MESSAGE 3...
THE SENSIBLE WEATHER PATTERN DOES NOT CHANGE MUCH FROM THE MID
TO LATTER PORTION OF THE WEEK. LOW TO MID LEVEL WEST TO
SOUTHWEST FLOW CONTINUES WITH A SERIES OF SHORT-WAVE IMPULSES
MOVING THROUGH THE NORTHERN PERIPHERY OF THE RIDGE OVER THE
SOUTHEAST AND FL IMPACTING THE REGION. THE MAIN FRONTAL BOUNDARY
REMAINS STATIONARY OVER NRN NY AND NORTHERN NEW ENGLAND.
ANOTHER PREFRONTAL DISTURBANCE AND A WAVE BRINGS ANOTHER BATCH
OF SHOWERS AND ISOLATED TO WIDELY SCATTERED T-STORMS. A FEW
COULD ONCE AGAIN BE ON THE STRONG SIDE NORTH AND WEST OF THE
CAPITAL REGION. MAX TEMPS IN THE 70S TO LOWER 80S WILL BE COMMON
EXCEPT OVER THE NORTHERN MTNS WHERE SOME 60S ARE POSSIBLE. THE
LATEST 01Z NBM YIELDS A 40-90% CHANCE FOR MAX TEMPS >80F FROM
THE CAPITAL DISTRICT SOUTH INTO THE MID HUDSON VALLEY, THE
SOUTHERN TACONICS AND NW CT. AS REFERENCED IN THE PREVIOUS
FORECAST DISCUSSION, THE RECORD AT KPOU ON WED COULD BE TIED OR
BROKEN, AND SEE THE CLIMATE SECTION BELOW FOR RECORDS.
SOME SIGNALS FROM THE MEDIUM GUIDANCE AND ENSEMBLES THAT THE
WARMEST DAY COULD BE THU WITH LOW AND MID LEVEL HEIGHTS
INCREASING. THE NBM HAS 30-50% PROBABILITIES ARE FAR NORTH AS
THE MOHAWK VALLEY AND PORTIONS OF SOUTHERN VT FOR MAX TEMPS >80F
POSSIBLE...60-90% PROBABILITIES ARE FORECASTED FROM THE
SOUTHERN CAPITAL REGION SOUTH AND EAST. WIDESPREAD UPPER 70S AND
LOWER 80S ARE LIKELY ON THU WITH THE BEST CHANCE FOR
SHOWERS/THUNDERSTORMS NORTH I-90 THU-THU NIGHT. A FEW STRONG
T-STORMS MAY BE POSSIBLE DEPENDING ON THE AMOUNT OF
INSTABILITY. THE COLD FRONT AND A MID AND UPPER LEVEL TROUGH
CONTINUES THE APRIL SHOWERY WEATHER ON FRI WITH SLIGHTLY COOLER
TEMPS IN THE 60S AND 70S. A BRIEF BREAK IN THE ACTIVE WEATHER
MAY OPEN THE WEEKEND WITH HIGH PRESSURE BUILDING IN, BUT
ANOTHER FRONT AND TROUGH BRINGS SHOWERS BACK IN TO CLOSE THE
WEEKEND. TEMPS STILL LOOK ABOVE NORMAL BY 10-15 DEGREES FOR
NEXT WEEKEND.
AVIATION /18Z MONDAY THROUGH SATURDAY/
FAST MOVING DISTURBANCE, AIDED BY A WEAK SURFACE TROUGH, HAS
BEEN ALLOWING FOR SOME LIGHT RAIN SHOWERS THIS AFTERNOON. BASED
ON RADAR TRENDS AND CAMS, BEST CHANCE FOR ADDITIONAL SHOWERS
WILL BE ACROSS NORTHERN AREAS NEAR KGFL. RECENT AND NEARBY
SURFACE OBSERVATIONS HAVE BEEN SHOWING LIMITED IMPACTS ON
VISIBILITY AND CEILINGS FROM THESE SHOWERS, DUE TO DRY AIR AT
LOW LEVELS AND FAIRLY LIMITED FORCING, SO WON'T EXPECT MUCH
IMPACT ON THE TAF SITES. WILL INCLUDE A BRIEF TEMPO FOR MVFR
CONDITIONS AT KGFL OVER NEXT FEW HOURS, OTHERWISE, IT SHOULD
STAY VFR THROUGH THE REST OF THE AFTERNOON HOURS. SOUTH TO
SOUTHWEST WINDS HAVE BEEN GUSTY, ALTHOUGH NOT NEARBY AS STRONG
AS WHAT WAS INDICATED IN THE PREVIOUS TAF. WILL CONTINUE TO
MENTION SUSTAINED WINDS OF 10 TO 15 KTS, WITH SOME GUSTS IN THE
20-26 KT RANGE, MAINLY FOR KALB AND KPSF THROUGH THE AFTERNOON
HOURS. THESE WINDS SHOULD DECREASE THIS EVENING WITH THE LOSS
OF DAYTIME MIXING.
FOR TONIGHT, FLYING CONDITIONS WILL GENERALLY BE VFR. THERE WILL
BE BKN-OVC CIGS AROUND 3500-5000 FT FOR A GOOD PORTION OF THE
OVERNIGHT, WITH SOME CLEARING LATE. A LINGERING BREEZE, DRY LOW
LEVELS AND ENOUGH CLOUDS SHOULD KEEP ANY FOG FROM DEVELOPING
TONIGHT. WESTERLY WINDS WILL GRADUALLY LOWER TO AROUND 5 KTS BY
THE LATE NIGHT HOURS.
FLYING CONDITIONS WILL START VFR FOR TUESDAY, BUT LOWERING
CEILINGS ARE EXPECTED BY AFTERNOON, AS A BAND OF SHOWERS AND
POSSIBLE THUNDERSTORMS APPROACH. WILL MENTION MVFR CIGS TOWARDS
MIDDAY WITH SOUTH TO SOUTHWEST WINDS AROUND 10 KTS. BEST CHANCE
FOR PRECIP WILL BE TOWARDS THE END OF THE TAF PERIOD (ENDING AS
18Z TUESDAY) AND INTO THE LATE AFTERNOON HOURS.
