Area forecast discussion, Aug 29, 3:46 PM EDT, 1 hour 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
346 PM EDT MON AUG 29 2011

.SYNOPSIS...
HIGH PRESSURE WILL BUILD IN FROM THE WEST AND DOMINATE OUR
WEATHER FOR MUCH OF THE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
HIGH PRESSURE WILL CONTROL THE WEATHER TONIGHT. A FEW THIN HIGH
CLOUDS MAY SKIRT THROUGH THE REGION...BUT CLEAR AND NEARLY CALM
CONDITIONS WILL RESULT IN TEMPERATURES FALLING RAPIDLY INTO THE
40S AND LOWER 50S.

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
A WEAK UPPER IMPULSE WILL BRUSH JUST NORTH OF THE REGION TOMORROW
AND WEDNESDAY...BUT SHOULD HAVE LITTLE TO NO EFFECT ON OUR REGION
EXCEPT FOR SOME PERIODS OF CLOUD COVER IN THE SOUTHERN
ADIRONDACKS. PROXIMITY OF SURFACE HIGH PRESSURE SHOULD KEEP THE
REGION DRY...AND WITH RELATIVELY SEASONABLE HIGH TEMPERATURES. LOW
TEMPERATURES WILL BE A LITTLE BELOW NORMAL. DRY WEATHER SHOULD
HELP THE REGION CLEAN UP AND DRY OFF AFTER THE STORM.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
WEAK HIGH PRESSURE WILL BE IN PLACE ACROSS THE REGION FOR THURSDAY
NIGHT THROUGH FRIDAY NIGHT...AS THE AREA IS SANDWICHED BETWEEN A
CUTOFF UPPER LEVEL LOW OVER THE WESTERN ATLANTIC AND AN APPROACHING
TROUGH MOVING THROUGH THE MIDWEST.  THIS SHOULD KEEP IT MAINLY RAIN
FREE ACROSS THE AREA...WITH TEMPS CLOSE TO SEASONAL AVERAGES.

BY SATURDAY...MID/HIGH CLOUDS WILL BEGIN TO INCREASE AS A FRONTAL
SYSTEM APPROACHES FROM THE WEST. IT SHOULD REMAIN DRY ACROSS MOST OF
THE AREA FOR DURING THE DAY. THE EXCEPTION MAY BE THE WESTERN
DACKS...WHERE SOME SHOWERS COULD APPROACH BY THE LATE AFTN HOURS.
WITH FORECASTED CAPE VALUES LOOKING RATHER LOW...WILL NOT MENTION
THUNDER AT THIS TIME. TEMPS LOOK TO BE IN THE 70S TO NEAR 80 IN MOST
VALLEY AREAS.

THE FRONT LOOKS TO CROSS THE AREA BETWEEN SATURDAY NIGHT AND SUNDAY
NIGHT.  THE 12 UTC GFS/ECMWF DON/T TOTALLY AGREE ON THE TIMING OF
THE FEATURE...SO WILL GO WITH CHC POPS FOR THIS ENTIRE TIME. HAVE
INCLUDED THUNDER FOR DURING THE DAY SUNDAY AS THERE MIGHT BE ENOUGH
INSTABILITY/FORCING TO ALLOW FOR THUNDERSTORMS DURING THE TIME OF
PEAK HEATING. MAX TEMPS ON SUNDAY LOOK TO BE IN THE 70S FOR MOST
AREAS.

THE ECMWF TRIES TO KEEP SHOWERS INTO MONDAY /LABOR DAY/ DUE TO THE
UPPER TROUGH OVERHEAD...WHILE THE GFS DOESN/T SEEM TO KEEP ENOUGH
MOISTURE AROUND FOR THIS TO HAPPEN. WILL GO WITH A BLEND OF THESE
TWO MODELS...AND KEEP JUST A LOW CHC OF SHOWERS FOR SOUTHEASTERN
PORTIONS OF THE AREA.  HOWEVER...WITH THE ECMWF LOOKING TO TREND
MORE TOWARDS THE GFS...IT COULD WIND UP BEING A DRY DAY ACROSS THE
ENTIRE AREA...WITH TEMPS GENERALLY RANGING FROM THE 60S TO MID 70S.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
MAINLY VFR CONDITIONS EXPECTED THROUGH THE TAF PERIOD ENDING AT 18Z
TUESDAY...THE EXCEPTION WILL LIKELY BE AT KGFL THIS EVENING AND
TONIGHT WHEN FOG WILL REDUCE VISIBILITIES TO MVFR...THEN TO
IFR/LIFR LATE AT NIGHT WITH KALB AND KPOU ALSO LIKELY TO HAVE MVFR
VSBYS IN FOG AFT 08Z. EXPECT THAT THE SKY CONDITIONS WILL BE
MAINLY FEW-SCT040-050 OR SKC DURING MUCH OF THE TAF PERIOD.
CONDITIONS WILL IMPROVE TO VFR AFTER ABOUT 11Z...AND CONTINUE
THROUGH TOMORROW MORNING.

WINDS WILL GENERALLY BE W-NW AT 8-12 KTS BEFORE BECOMING LIGHT
AND VARIABLE OR CALM EARLY THIS EVENING THROUGH ABOUT 12Z TUESDAY.
WINDS WILL BE SOUTHWEST TO NORTHWEST AT LESS THAN 10 KT TOMORROW
MORNING.

OUTLOOK...
TUE-WED...VFR. NO SIG WX.

WEDNESDAY. WINDS WILL BE LIGHT AND VARIABLE AT LESS THAN 15 MPH.
WINDS WILL BE SOUTHWEST TO NORTHWEST AT 15 MPH OR LESS TOMORROW
AND WEDNESDAY.

&&

.HYDROLOGY...
FLASH FLOOD WATCH WILL CONTINUE FOR EASTERN SCHENECTADY...EASTERN
ALBANY AND SOUTHERN SARATOGA COUNTIES DUE TO TYPE B SITUATION AT
VISCHER FERRY DAM. GILBOA DAM AND BLENHEIM GILBOA POWER PROJECT
DAMS NOW UNDER NORMAL CONDITIONS.

ONGOING FLOODS...PLEASE REFER TO FLOOD WARNINGS AND STATEMENTS FOR
THE LATEST INFORMATION. MAINLY DRY WEATHER IS EXPECTED FOR THE
WORK WEEK WHICH WILL ALLOW AREAS RIVERS AND STREAMS TO RECEDE.
LARGER RIVERS SUCH AS THE MOHAWK...HUDSON AND HOUSATONIC WERE NEAR
CREST OR SLOWLY RISING. MODERATE TO MAJOR FLOODING IS STILL
OCCURRING ON SOME RIVERS AND STREAMS EVEN THOUGH THEY MAY BE
