DISCUSSION
KEY MESSAGE 1...
SATELLITE IMAGERY SHOWING CLOUDS INCREASING, WITH WIDELY
SCATTERED SHOWERS DEVELOPING WITH A SURGE OF ISENTROPIC LIFT
AHEAD OF A NORTHWARD ADVANCING WARM FRONT. LATEST CAMS MAINLY
FOCUSING ON AREAS WEST OF THE HUDSON VALLEY, WHICH IS WHERE POPS
ARE HIGHEST(30-40%). AN ISOLATED/BRIEF SHOWER CANNOT BE RULED
OUT ELSEWHERE THOUGH. PATCHY FREEZING DRIZZLE MAY OCCUR IN THE
HIGHEST ELEVATIONS > 1500 FT IN THE S. GREENS TONIGHT WITH LOW
LEVEL MOISTURE TRAPPED BENEATH A SIGNIFICANT INVERSION WITH
SURFACE TEMPERATURES BELOW FREEZING. COVERAGE SHOULD BE TOO
LIMITED TO CAUSE WIDESPREAD IMPACTS. SOUTHERLY WINDS WILL
INCREASE TONIGHT AS LOW PRESSURE TRACKS IN SE CANADA WHILE HIGH
PRESSURE REMAINS IN PLACE OVER THE CANADIAN MARITIMES. GUSTS OF
25-35 MPH WILL OCCUR IN TYPICAL SOUTHERLY FACING SLOPES OF THE
HIGHER TERRAIN AND S-N ORIENTED VALLEYS. A ~3-5 PERIOD OF RAIN
WILL THEN OCCUR ALONG THE SYSTEM'S COLD FRONT LATE TONIGHT INTO
SUNDAY, SPREADING FROM NW TO SE ACROSS THE AREA. IT APPEARS OUR
REGION WILL NOT GET INTO A TRUE WARM SECTOR, SO THERE IS ONLY A
SLIGHT CHANCE OF A FEW T-STORMS WITH ONLY LIMITED ELEVATED
INSTABILITY (MUCAPE ~100 J/KG) WELL NORTH/WEST OF ALBANY TONIGHT
AND WELL SOUTH/EAST LATE SUN MORNING. THE RAIN WILL MOVE INTO
THE CAPITAL DISTRICT EARLY TO MID MORNING, THEN EXITING BY
AFTERNOON. AREAS SOUTH/EAST OF ALBANY WILL STILL SEE RAIN INTO
EARLY SUN AFTERNOON BEFORE ENDING. QPF IS IN THE 0.25-0.60"
RANGE, WHICH SHOULD NOT RESULT IN ANY ADDITIONAL HYDRO IMPACTS.
LEVELS ALONG THE WEST CANADA CREEK AT HINCKLEY MAY CONTINUE TO
FLUCTUATE NEAR MINOR FLOOD STAGE FOR THE NEXT FEW DAYS.
KEY MESSAGE 2...
COLD ADVECTION COMMENCES LATE SUN INTO SUN NIGHT, AS AN UPPER
LEVEL TROUGH SETTLES IN ACROSS THE GREAT LAKES AND NORTHEAST.
WHILE SOME UPSLOPE SNOW SHOWERS MAY OCCUR INTO THE W.
ADIRONDACKS SUN NIGHT INTO MON, MOST OF THE AREA SHOULD BE DRY.
A MORE VIGOROUS DISTURBANCE PASSING THROUGH THE MEAN TROUGH
LOOKS TO BRING SCATTERED TO NUMEROUS SNOW SHOWERS LATE MON INTO
TUE. DUE TO DIURNAL EFFECTS, SNOW SHOWERS EXPECTED TO MIX WITH
RAIN IN LOWER ELEVATIONS DURING DAYLIGHT HOURS ON TUE, ALTHOUGH
THERE COULD BE A DUSTING OF ACCUMULATION ON MAINLY GRASSY
SURFACES PRIOR TO SUNRISE. HIGHER ELEVATIONS MAY SEE A COATING
TO INCH OF SNOW, WHICH COULD RESULT IN SOME ISOLATED SLIPPERY
TRAVEL. TEMPERATURES WILL BE BELOW NORMAL THROUGH WED, WITH THE
COLDEST STRETCH MON-TUE NIGHT. 850 MB TEMPERATURE ANOMALIES ARE
FORECAST TO BE -1 TO -3 STDEV BENEATH THE PERSISTENT UPPER LEVEL
TROUGH. A GUSTY NW BREEZE WILL MAKE IT FEEL COLDER TOO. HIGHS
EXPECTED TO RANGE FROM THE MID 30S TO LOWER 50S MON AND LOWER
30S TO MID 40S TUE. LOWS SHOULD RANGE FROM THE MID 20S TO MID
30S MON NIGHT AND AROUND 20F TO LOWER 30S TUE NIGHT.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THROUGH 00Z MONDAY, CIGS WILL CONTINUE TO LOWER FROM VFR TO MVFR
LEVELS OVERNIGHT, LAST OCCURRING AT KGFL, WHILE VSBYS REMAIN
MAINLY VFR UNTIL AFTER 08Z/SUN ONCE SPOTTY SHOWERS DEVELOP. AS
THE MAIN COLD FRONT AND AREA OF LIGHT TO MODERATE RAIN SHOWERS
MOVES WEST TO EAST SUNDAY MORNING, EXPECT WIDESPREAD MVFR TO
OCCASIONAL IFR CONDITIONS (BOTH VSBYS AND CIGS). VSBYS SHOULD
IMPROVE TO VFR BY 17Z-20Z/SUN, HOWEVER OCCASIONAL MVFR CIGS MAY
LINGER WELL INTO SUNDAY AFTERNOON, ESPECIALLY AT KPSF.
SOUTHEAST WINDS WILL INCREASE TO 8-15 KT THIS EVENING WITH SOME
GUSTS OF 25-30 KT POSSIBLE, ESPECIALLY AT KALB AND KPSF.
SOUTHEAST TO SOUTH WINDS WILL GRADUALLY DECREASE IN MAGNITUDE
AFTER 08Z/SUN TO 5-10 KT, HOWEVER OCCASIONAL GUSTS UP TO 20-25
KT WILL LINGER THROUGH SUNDAY MORNING AT KALB AND KPSF. WINDS
WILL SHIFT INTO THE WEST/NORTHWEST WITH THE COLD FRONTAL PASSAGE
DURING THE EARLY AFTERNOON AND INCREASE TO 8-12 KT WITH SOME
GUSTS UP TO 25 KT BY LATE AFTERNOON/EARLY EVENING. LOW LEVEL
WIND SHEAR IS EXPECTED OVERNIGHT, ESPECIALLY AT KPOU AND KPSF AS
WINDS AROUND 2000 FT AGL INCREASE FROM THE SOUTH/SOUTHWEST TO
40-50 KT WHILE SURFACE WINDS DECREASE TO LESS THAN 12 KT.
