WHAT HAS CHANGED
THE HEAT ADVISORY FOR TOMORROW (TUESDAY) HAS BEEN EXPANDED TO
NOW INCLUDE SCHOHARIE, WESTERN ALBANY, EASTERN RENSSELAER,
WESTERN GREENE, WESTERN ULSTER, AND WESTERN WINDHAM COUNTIES
WHERE HEAT INDEX VALUES WILL REACH UP TO 101 DEGREES
FAHRENHEIT. ALL ELSE REMAINS ALIGNED WITH THE PREVIOUS FORECAST.
KEY MESSAGES
1) THE COMBINATION OF HIGH HEAT AND HUMIDITY WILL MAKE FOR
DANGEROUS HEAT INDICES ACROSS PORTIONS OF EASTERN NEW YORK AND
WESTERN NEW ENGLAND ON TUESDAY AND WEDNESDAY.
2) THERE IS POTENTIAL FOR ISOLATED SHOWERS AND NON-SEVERE
THUNDERSTORMS SEVERAL DAYS THIS WEEK, BUT NO APPRECIABLE RAIN IS
ANTICIPATED UNTIL AT LEAST THIS WEEKEND.
DISCUSSION
KEY MESSAGE 1
VERY HOT CONDITIONS RETURN TO EASTERN NEW YORK AND WESTERN NEW
ENGLAND TOMORROW AS A NEARLY 600 DM RIDGE, CURRENTLY BUILDING
OVER THE NORTH-CENTRAL CONUS, SHIFTS EASTWARD. THE SUBSTANTIAL
INCREASE IN GEOPOTENTIAL HEIGHT WILL TRANSLATE TO AN EVEN
GREATER RISE IN 850 MB TEMPERATURES WHICH LOOK TO RANGE FROM
ABOUT +20C TO +23C (2.5 TO NEARLY 3.5 STDEVS ABOVE NORMAL).
GIVEN DEEP, LOW-LEVEL MIXING AND UNOBSTRUCTED RADIATION FROM
CLEAR SKIES, HIGH TEMPERATURES AT THE SURFACE WILL SUBSEQUENTLY
RISE WIDELY TO THE MID/UPPER 80S TO UPPER 90S. AND WHILE
DEWPOINTS IN THE LOW TO UPPER 60S WILL CERTAINLY ADD TO THE
OPPRESSIVE FEELING OF THE HEAT, WESTERLY FLOW COULD ENHANCE
LOCALIZED WARMING AND DRYING SUCH THAT THE REAL EFFECTS OF THE
HEAT ARE FELT PRIMARILY FROM THE TEMPERATURES THEMSELVES. THAT
BEING SAID, THIS COMBINATION OF TEMPERATURES AND DEWPOINTS WILL
MAKE FOR FEELS LIKE TEMPERATURES, OR HEAT INDICES, IN THE UPPER
90S TO LOW 100S ACROSS LARGE VALLEY AREAS. THEREFORE, THE
PREVIOUS HEAT ADVISORY FOR TOMORROW STANDS WITH ADDITIONAL ZONES
HAVING BEEN ADDED GIVEN INCREASED CONFIDENCE IN 95 DEGREE
FAHRENHEIT HEAT INDICES.
A LARGE UPPER-LEVEL LOW WILL TOP THE RIDGE IN NORTHEAST CANADA
ON WEDNESDAY, SHUNTING THE HIGHEST HEIGHTS TO OUR SOUTH. A COLD
FRONT WILL LIKEWISE TRACK THROUGH OUR REGION THROUGHOUT THE DAY,
LIMITING THE POTENTIAL RISE OF TEMPERATURES AND DEWPOINTS.
STILL, DEEP MIXING INTO AN 850MB LAYER THAT WILL STILL MAINTAIN
TEMPERATURES OF +13C TO +16C, HIGH TEMPERATURES WILL LARGELY
REACH THE 80S TO 90S. IN THE MID-HUDSON VALLEY AND SOUTHERN
LITCHFIELD COUNTY, WHERE TEMPERATURES AND DEWPOINTS WILL HAVE
THE GREATEST TIME TO RISE AHEAD OF THE FRONT, HEAT INDICES WILL
REACH THE MID TO UPPER 90S. THEREFORE, HEAT ADVISORIES REMAIN IN
EFFECT FOR THESE AREAS ON WEDNESDAY. CAUTION IS ADVISED BOTH
TOMORROW AND WEDNESDAY PARTICULARLY TO INDIVIDUALS WHO MAY BE
MORE SUSCEPTIBLE TO HEAT-RELATED ILLNESS. THESE TEMPERATURES AND
HEAT INDICES WILL BE DANGEROUS IF PROPER BEHAVIORS FOR
MITIGATING HEAT-RELATED ILLNESSES ARE NOT ADHERED TO.
KEY MESSAGE 2
AS A WEAK, UPPER-LEVEL SHORTWAVE PASSES OVERHEAD THIS AFTERNOON
INTO THIS EVENING, ISOLATED SHOWERS OF EARLIER THIS MORNING AND
THIS AFTERNOON WILL CONTINUE PARTICULARLY FOR PORTIONS OF THE
MID-HUDSON VALLEY AND SOUTHWEST NEW ENGLAND. TOMORROW, WHILE WE
WILL BE WELL UNDER THE INFLUENCE OF THE UPPER RIDGE WHICH SHOULD
INHIBIT ANY SHOWERS OR THUNDERSTORMS, THE INCOMING COLD FRONT
BENEATH ANOTHER STRONGER UPPER-LEVEL SHORTWAVE SHOULD PROMOTE
ENOUGH FORCING TO ALLOW ISOLATED SHOWERS AND POTENTIALLY A NON-
SEVERE THUNDERSTORM TO DEVELOP LATE IN THE EVENING IN THE
SOUTHERN ADIRONDACKS. THE REST OF THE WEEK SHOULD, TOO, REMAIN
MOSTLY DRY AS THE RIDGE BEGINS TO BREAKDOWN, BUT BY THIS
WEEKEND, MORE WIDESPREAD CHANCES FOR RAIN SHOWERS RETURN AS A
LOW PRESSURE SYSTEM APPROACHES FROM THE GREAT LAKES. THIS SYSTEM
COULD POTENTIALLY BRING MORE APPRECIABLE RAIN WHICH WILL BE
GREATLY NEEDED BY THAT POINT.
AVIATION /18Z MONDAY THROUGH SATURDAY/
THROUGH 18Z/TUESDAY...VFR CONDITIONS ARE EXPECTED TO PREVAIL ACROSS
ALL SITES THROUGH MOST OF THE TAF PERIOD OUTSIDE OF SOME ISOLATED
SHOWERS/THUNDERSTORMS. CURRENT KENX RADAR SHOWS SOME SPOTS OF BRIEF
DOWNPOURS MOVING THROUGH FROM THE NORTHWEST THAT COULD BRIEFLY LOWER
VSBYS AT KALB, KPOU, AND KPSF OVER THE NEXT FEW HOURS, IF ONE PASSES
OVER A TERMINAL. A RUMBLE OF THUNDER ALSO CAN'T BE RULED OUT,
ESPECIALLY AT KPOU AND KPSF. OTHERWISE MAINLY FEW AND SCATTERED LOW
AND HIGH LEVEL CLOUDS PASS THROUGH AS A HIGH PRESSURE SYSTEM BUILDS
OVER THE REGION. WINDS WILL BE OUT OF THE SOUTHWEST THIS AFTERNOON
AND EVENING WITH SPEEDS AROUND 10 KT AND GUSTS 15-18 KT. WINDS THEN
BECOME LIGHT AND VARIABLE OVERNIGHT BEFORE QUICKLY PICKING BACK UP
WITH DAYBREAK. THERE MAY BE ENOUGH WIND TO PREVENT FOG FROM
DEVELOPING TONIGHT. WINDS TOMORROW REMAIN OUT OF THE SOUTHWEST WITH
SUSTAINED SPEEDS 10-15 KT AND GUSTS UP TO 25 KT.
