Area forecast discussion, Jul 15, 1:45 PM EDT, 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY NY 145 PM EDT SUN JUL 15 2007 .SYNOPSIS... A COLD FRONT WILL MOVE ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND TODAY. SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR WITH THE FRONT. A FEW OF THE THUNDERSTORMS MAY PRODUCE DAMAGING WINDS. A WEAK RIDGE OF HIGH PRESSURE WILL BUILD IN FROM THE LOWER GREAT LAKES REGION SUNDAY NIGHT. THE HIGH WILL CREST OVER NEW YORK AND NEW ENGLAND ON MONDAY WITH SEASONABLE TEMPERATURES AND DRY WEATHER. ANOTHER DISTURBANCE WILL BRING SOME SCATTERED SHOWERS AND THUNDERSTORMS TO THE REGION ON TUESDAY. && .NEAR TERM /UNTIL 8 PM THIS EVENING/... ...SEVERE THUNDERSTORM WATCH 519 IN EFFECT UNTIL 800 PM... THUNDERSTORMS HAVE BRIEFLY ERUPTED ALONG WHAT APPEARS TO BE LINES OF CONVERGENCE...ONE RIGHT OVER THE CAPITAL DISTRICT...WITH A COUPLE CELLS WE HAVE WARNED FOR. WE EVEN GOT VERIFICATION ON THAT. (PLEASE REFER TO OUR LOCAL STORM REPORT (LSR) FOR ALL DETAILS. ANOTHER LINE...ALBEIT WEAKER LIES TO OUR WEST...WITH THE REAL COLD FRONT. SPC HAS PLACED OUR ENTIRE AREA INTO A WATCH BOX. WHILE LAPSE RATES ARE NOT THAT IMPRESSIVE...SBCAPES OF 1500-2000 J/KG COMBINED WITH PRETTY HEFT UNIDIRECTIONAL SHEAR...HAVE RESULTED IN SKINNY BUT POTENT UPDRAFTS. WE HAVE EVEN NOTED SOME BROAD ROTATION WITH THESE CELLS. THE WATCH IS GOOD THROUGH 8PM...WHEN WE EXPECT THE COLD FRONT TO FINALLY PRETTY MUCH CLEAR OUR REGION. THE POTENTIAL IS THERE FOR ANY THUNDERSTORM TO PRODUCE DESTRUCTIVE WIND GUSTS TO 60 MPH AND PENNY SIZE HAIL AS WELL AS FREQUENT CLOUD TO GROUND LIGHTNING. THINGS SHOULD QUIET DOWN TONIGHT AS DRIER AIR MOVES IN. && .SHORT TERM /8 PM THIS EVENING THROUGH MONDAY NIGHT/... MONDAY LOOKS LIKE ANOTHER WINNER WITH HIGH PRESSURE SETTLING OVER UPSTATE NY AND NEW ENGLAND. 850 MB TEMPS OF 12-14C WITH FULL SUNSHINE SHOULD YIELD HIGHS IN THE U70S TO L80S IN THE VALLEYS AND U60S TO MID 70S IN THE HILLS AND MTNS. HUMIDITY LEVELS WILL CONTINUE TO BE QUITE COMFORTABLE. AN ISOLATED INSTABILITY SHOWER MAY POP OVER THE SRN DACKS LATE IN THE DAY. WE PLACED A SLIGHT CHANCE VALUE THERE. MONDAY NIGHT...A SERIOUS DETERMINISTIC MODEL DIVERGENCE OCCURRED BETWEEN THE NAM AND THE GFS/CAN GGEM/UKMET IN THIS PERIOD. THE NAM BRINGS A WAVE FROM SW TO NE ACROSS W-CNTRL 03Z-09Z WITH A SHARPER H500 TROUGH. THE GFS/UKMET/CAN GGEM ARE FLATTER WITH THE WEAK SFC HIGH HANGING ON. THE POTENT SHORT WAVE REMAINS UPSTREAM OVER CNTRL GREAT LAKES REGION. WE DISCARDED THE 00Z WRF SOLUTION /SO DID HPC/ BASED ON THE POOR TIMING AND THE PLETHORA OF QPF IT WAS DUMPING. WE PLACED SOME SLIGHT CHANCE VALUES FOR SHRAS/TSRAS IN FROM WEST TO EAST OVER THE FCST AREA DUE TO WEAK WARM AIR ADVECTION WITH A WARM FRONT TRYING TO NUDGE IN FROM THE SOUTH. TUESDAY...A SHORT WAVE AND ITS ASSOCIATED SFC REFLECTION MOVE NEAR THE NY/PA BORDER PRODUCING SOME SHRAS/TSRAS. THE WAVE MOVES ALONG THE OLD FRONTAL BOUNDARY THAT PASSES THROUGH THE REGION THIS AFTERNOON. THE BAROCLINIC ZONE IS FAIRLY NOTABLE. THE SRN HLF OF THE FCST AREA MAY GET INTO THE RIGHT REAR QUADRANT OF AN H300 JET STREAK HELPING ENHANCE THE LIFT. WE WENT WITH FAIRLY HIGH CHANCE VALUES FROM THE CAPITAL REGION/MOHAWK VALLEY SOUTHWARD ON TUE. && .LONG TERM /TUESDAY THROUGH SATURDAY/... A STATIONARY FRONT REMAINS DRAPED ALONG/NEAR THE MASON DIXON LINE WITH WEAK DISTURBANCES MOVING ALONG IT TUESDAY NIGHT INTO WED. THIS WILL KEEP A THREAT OF SHOWERS IN TUE NIGHT INTO WED NIGHT...ESPECIALLY FOR THE SRN HLF OF THE FCST AREA. HIGH PRESSURE BUILDS SOUTH/SOUTHEAST FROM QUEBEC FOR THU. ANOTHER FRONT IN THE NW FLOW ALOFT DROPS SOUTHEAST OF HUDSON BAY WITH A SLIGHT CHANCE OF SHOWERS FOR FRI. A COOL AND DRY AIR MASS BUILDS SE FROM THE UPPER GREAT LAKES REGION FOR SAT. && .AVIATION /18Z SUNDAY THROUGH THURSDAY/... ALREADY HAD THUNDER AT KALB. ADDITIONAL SCATTERED THUNDERSTORMS MIGHT IMPACT ALL TERMINALS LATER THIS AFTERNOON...AND THERE IS A REMOTE CHANCE ANY OF THEM COULD BE SEVERE ALONG WITH FREQUENT LIGHTNING AND BLINDING RAINFALL. MIGHT EVEN DEAL WITH THE LINE AS THE THE COLD FRONT SLICES THROUGH LATER THIS AFTERNOON. FOR TONIGHT...LOOK FOR A CLEAR TO PARTLY SKY. TEMPS WILL DROP BACK INTO THE 50S. THE CROSSOVER TEMP AT KGFL LOOKS TO BE IN THE LOWER 50S...AND WE ARE FORECASTING TEMPS AROUND 50. WITH THE WIND DIMINISHING...WE DO EXPECT IFR FOG THERE AFTER 08Z BUT LITTLE OR NOT FOG AT OTHER TERMINALS. MON...VFR...NO SIGNIFICANT WEATHER. TUE...VFR-MVFR WITH A CHANCE OF CONVECTION. WED AND THU...VFR...CHC OF SHOWERS. && .HYDROLOGY... PRECIPITABLE WATER VALUES ARE EXPECTED TO INCREASE TO 1.25 TO 1.50 INCHES...ESPECIALLY SOUTH OF THE CAPITAL REGION...AHEAD OF A COLD FRONT AS IT MOVES SOUTHEAST ACROSS THE AREA. K-INDEX VALUES SHOULD REMAIN BELOW 35...AN INDICATOR FOR VERY HEAVY DOWNPOURS. BASIN AVERAGE RAINFALL OF UP TO A QUARTER OF AN INCH ARE EXPECTED. NO HYDROLOGICAL PROBLEMS ARE NOT ANTICIPATED. && .ALY WATCHES/WARNINGS/ADVISORIES... SEVERE THUNDERSTORM WATCH 519 FOR ALL EVERY COUNTY IN OUR WARNING AREA UNTIL 8PM SUNDAY. && NEAR TERM...HWJIV AVIATION...HWJIV
