DISCUSSION
KEY MESSAGE 1...
MUCH COOLER AIR MASS WILL OVERSPREAD THE REGION TODAY INTO
TONIGHT IN THE WAKE OF COLD FRONTAL PASSAGE. THE COMBINATION OF
DECENT PRESSURE RISES AMID COLD AIR ADVECTION AND DEEP MIXING
SHOULD ALLOW FOR GUSTY NORTHWEST WINDS AT TIMES TODAY REACHING
25-30 MPH. MAX TEMPS WILL REACH THE UPPER 60S TO LOWER 70S IN
VALLEYS, AND ONLY 50S TO LOWER 60S ACROSS HIGHER HIGHER PEAKS OF
THE ADIRONDACKS AND SOUTHERN VT.
AS HIGH PRESSURE BUILDS OVERHEAD TONIGHT, WINDS WILL TREND TO
CALM AMID THE COOL AND VERY DRY AIRMASS WITH PWAT'S DROPPING TO
0.40"-0.50" (-1 TO -2 SD), ALLOWING FOR STRONG RADIATIONAL
COOLING TO COMMENCE AFTER SUNSET. LOW TEMPERATURES BY DAYBREAK
TUESDAY SHOULD FALL INTO THE 40S FOR MOST AREAS, EXCEPT MID TO
UPPER 30S ACROSS PORTIONS OF THE SOUTHERN ADIRONDACKS/SOUTHERN
VT AND EASTERN CATSKILLS. SOME PATCHY FROST IS EXPECTED IN THE
MORE SHELTERED AREAS WITHIN THE SW ADIRONDACKS AND POSSIBLY
EASTERN CATSKILLS. HOWEVER, COVERAGE POTENTIAL FOR FROST LOOKS
ISOLATED AT THIS TIME, THEREFORE NO FROST ADVISORY ISSUANCE.
NEVERTHELESS, THOSE WITH SENSITIVE PLANTS/VEGETATION MAY WANT TO
TAKE PRECAUTIONS IN THESE AREAS AS MIN TEMPS DROP INTO THE
MID/UPPER 30S.
KEY MESSAGE 2...
TEMPS SHOULD REBOUND QUICKLY BY MIDWEEK, AS STRONG MID LEVEL
RIDGING BUILDS INTO THE REGION. MAX TEMPS SHOULD REACH AT LEAST
INTO THE 70S, WITH SOME POSSIBILITY (30-70%) FOR VALLEY AREAS
NEAR AND SOUTH OF ALBANY TO REACH NEAR OR ABOVE 80 WED/THU.
A WEAK COLD FRONT APPROACHING FROM THE NORTH COULD TRIGGER
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WEDNESDAY INTO
THURSDAY, ALTHOUGH THERE REMAINS UNCERTAINTY REGARDING POTENTIAL
COVERAGE OF SHOWERS/STORMS, AND ALSO PLACEMENT OF HIGHEST
CHANCES, WHICH WILL BE TIED TO THE ACTUAL FRONTAL LOCATION WHICH
COULD STALL SOMEWHERE ACROSS THE REGION DURING THIS TIME.
AVIATION /06Z MONDAY THROUGH FRIDAY/
THROUGH 06Z/TUE, A COLD FRONT WILL CROSS THE TAF SITES FROM NW

THE ONLY EXCEPTIONS WILL BE BRIEF PERIODS OF MVFR/IFR CIGS
THROUGH 08Z/MON AT KPSF DUE TO UPSLOPE CLOUDS, AND ALSO BRIEF
LOW CLOUDS/FOG THAT DEVELOP PRIOR TO THE COLD FRONTAL PASSAGE AT
KPOU. OTHERWISE, VFR CONDITIONS SHOULD PREVAIL FOR THE NEXT 24
HOURS.
LIGHT/VARIABLE WINDS WILL SHIFT INTO THE WEST TO NORTHWEST AND
INCREASE TO 8-12 KT BETWEEN 08Z-10Z/MON WITH SOME GUSTS UP TO
20-25 KT POSSIBLE. THESE WINDS AND GUSTS SHOULD THEN PERSIST
