.SHORT TERM (TONIGHT THROUGH THURSDAY)...WARM AND HUMID AIR MASS
CONTINUES ACROSS THE NORTHEAST.  SURFACE OBSERVATIONS SHOWING MANY
LOCATION IN THE MIDDLE 70S FOR DEW POINTS ACROSS THE CWA.  FURTHER
SOUTH...DEWPOINTS AROUND 77.  LATEST RADAR PICTURE SHOWING CELLS
POPPING UP ACROSS THE FORECAST AREA.   VIL OF DAY AROUND 66 FOR
TODAY.  WITH THIS TYPE OF AIRMASS WE ARE IN...FLASH FLOODING WILL BE
FAVORED...ESPECIALLY WITH ANY TRAINING ECHOS THAT DO DEVELOP.  KENX
RADAR AND ADJACENT RADARS HAVE SHOWN ISOLATED AMOUNTS OVER 2 INCHES
ACROSS THE CATSKILL AREA AND EASTERN ALBANY COUNTY.  PRECIP WATER ON
MODEL SOUNDINGS ARE VERY HIGH WITH VALUES OVER 2 INCHES TODAY. A LOW
PRESSURE SYSTEM OVER CENTRAL CANADA WITH A TRAILERING COLD FRONT
WILL CONTINUE TO MOVE EASTWARD AND START TO APPROACH THE REGION
OVERNIGHT.  WILL CONTINUE WITH HIGH CHANCE OF SHOWERS AND
THUNDERSTORMS FOR TONIGHT...AND THEN TAPER OFF TO SLIGHT CHANCE OF
SHOWERS OVERNIGHT.

TUESDAY...BIG FEATURE OF THE DAY WILL BE A COLD FRONT THAT WILL PUT
AN END TO THE HUMIDITY...BUT NOT THE HEAT.  PRECIP WATER AMOUNTS
VERY HIGH AGAIN FOR TUESDAY WITH AMOUNTS NEAR 2 INCHES.  THE COLD
FRONT OVER THE GREAT LAKES REGION...WILL MOVE EASTWARD INTO THE CWA
ON TUESDAY. LATEST MODEL TRENDS TAKE THE FRONT THROUGH THE CWA
DURING THE AFTERNOON AND OUT OF THE CWA BY 0000Z.  OVERALL TUESDAY
LOOKS TO BE OUR BEST DAY OF CONVECTION WITH THE LIFT FROM THE
FRONT.  THERE WILL BE A GOOD AMOUNT OF CONVECTIVE AVAILABLE
POTENTIAL ENERGY DURING THE AFTERNOON WITH HIGH DEWPOINTS.

WEDNESDAY AND THURSDAY...THE FRONT WILL BE THROUGH THE AREA AND HIGH
PRESSURE WILL BUILD INTO THE REGION.  THE HUMIDITY WILL BE OUT OF
THE REGION...HOWEVER THE HEAT WILL REMAIN WITH 850 TEMPERATURES
CLOSE TO +16 ON WEDNESDAY AND THURSDAY.
&&

.LONG TERM (FRIDAY THROUGH MONDAY)...ANOTHER WEAK FRONT WILL MOVE
THROUGH THE REGION ON FRIDAY.  THIS FRONT SHOULD BE THROUGH THE
REGION EARLY FRIDAY.  TIMING OF THE FRONT NOT FAVORABLE FOR MAJOR
CONVECTION PROBLEMS.  BY SATURDAY AND SUNDAY...HIGH PRESSURE WILL
BUILD INTO THE REGION.  TEMPERATURES WILL RETURN TO THEIR NORMAL
LEVELS FOR THE WEEKEND. BY MONDAY...THERE WAS A DIFFERENCE BETWEEN
THE 06Z AND 12Z RUN OF THE GFS.  THE 06Z RUN TRIES TO GENERATE A LOW
PRESSURE SYSTEM AT 500MB.
&&

.AVIATION...MAINLY VFR CONDITIONS AT KGFL/KALB/KPOU THIS AFTERNOON
AND EVENING WITH OCCASIONAL REDUCTIONS TO MVFR/IFR CIGS/VSBYS DUE TO
SHWRS/TSTMS. ALSO SOME VSBY REDUCTIONS TO MVFR DUE TO HAZE. DURING
THE NIGHT MVFR AND POSSIBLE IFR CIGS WILL BECOME MORE WIDESPREAD AS
A STRATUS DECK FORMS ONCE AGAIN ACROSS THE REGION AND LINGERS INTO
LATE MORNING ON TUESDAY. DURING THIS PERIOD VSBY REDUCTIONS TO MVFR
AND POSSIBLY IFR WILL OCCUR DUE TO HZ/BR AND POSSIBLE SHWRS.
&&

.HYDROLOGY...MAIN STEM RIVERS CONTINUE TO BE WELL BELOW FLOOD STAGE.
SCT SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH TONIGHT...AND
BECOME MORE NUMEROUS TUESDAY UNTIL PASSAGE OF A COLD FRONT DURING
THE AFTERNOON AND EVENING.  RAINFALL IS LIKELY TO BE QUITE HEAVY IN
SOME THUNDERSTORMS AND COULD TRIGGER FLOODING ON PAVED AREAS...AND
IN OTHER POORLY DRAINED LOCATIONS...AND SMALL CREEKS AND STREAMS
WOULD BE VULNERABLE IF TRAINING OCCURS. HOWEVER....NO FLOODING IS
EXPECTED ON THE MAJOR RIVERS FOR MUCH...IF NOT ALL OF THE COMING
WEEK AS HEAVY RAINFALL IS NOT EXPECTED TO COVER A LARGE ENOUGH AREA
TO PUSH THE RIVERS ABOVE FLOOD STAGE. WEDNESDAY AND THURSDAY LOOK TO
BE DRY AT THIS POINT.
