AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE UPTON NY 330 PM EDT WED JUL 14 2004 .SHORT TERM (THROUGH THURSDAY)... VIGOROUS UPPER TROUGH OVER THE EASTERN GREAT LAKES WILL PUSH INTO CENTRAL NEW YORK AND PENNSYLVANIA THIS AFTERNOON...THEN DEEPEN WITH CUTOFF LOW PRESSURE AND SHORTWAVES ROTATING AROUND THE BASE...PERSISTING OVER THE NORTHEAST THROUGH THE END OF THE WEEK. AT THE SURFACE...MAIN CUTOFF LOW PRESSURE OVER THE EASTERN GREAT LAKES WILL REMAIN STACKED UNDER THE UPPER LOW. WARM FRONT IS CURRENTLY MOVING THROUGH WESTERN NEW YORK AND CENTRAL PENNSYLVANIA AND COLD FRONT JUST BEHIND IT....WITH NICE BAND OF CONVECTION FIRING WITH THETA-E RIDGE...LEADING EDGE OF SHORTWAVE ENERGY...AND IN AN AREA OF MID-LEVEL DRYING. WARM FRONT AND ASSOCIATED ACTIVITY SHOULD WEAKEN AS IT MOVES FARTHER EAST INTO A MORE STABLE AIRMASS AND AS SHORTWAVE SLOWS EASTWARD PROGRESS THIS AFTERNOON. SHORTWAVE WILL ROTATE AROUND UPPER LOW TONIGHT WITH SURFACE COLD FRONT SWINGING THROUGH THE REGION AROUND 06Z TONIGHT. BEST CHANCE FOR WIDESPREAD TSRA/SHRA ACTIVITY WILL BE FROM WEST TO EAST FROM 00Z TO 06Z AHEAD OF THE COLD FRONT...WITH INCREASING VORTICITY ADVECTION...MARGINAL SURFACE INSTABILITY...A 30 KT LOW-LEVEL JET...AND THETA-E RIDGE MOVING THROUGH THE AREA. SEVERE THREAT SHOULD BE ISOLATED AND FOR THE MOST PART UNTIL AROUND 00Z OVER WESTERN ZONES...WITH MORE STABILITY OVER THE REGION THEN OVER CWAS TO THE WEST...AND WITH TIMING OF FRONT AFTER DARK. IN THE NEAR TERM WILL HAVE TO WATCH SEVERE THUNDERSTORM OVER HUNTERDON COUNTY IN CENTRAL NEW JERSEY...MOVING NE TOWARD UNION AND ESSEX COUNTIES. THIS STORM SHOULD WEAKEN AS IT CONTINUES EAST INTO OUR REGION...BUT STILL CAPABLE OF SMALL HAIL AND GUSTY WINDS. HEAVY RAINFALL SEEMS TO BEING THE BIGGEST CONCERN THEREAFTER WITH PWATS OF 1.5-1.75 INCHES. SINCE GENERAL RAINFALL WILL BE BELOW FFG AND FFH GUIDANCE AND AREA RIVERS HAVE HAD OPPORTUNITY TO RECEDE A BIT OVER THE LAST 24 HRS...NOT EXPECTING ANY WIDESPREAD FLOODING PROBLEMS. ISOLATED URBAN AND SMALL STREAM FLOODING LOOKS TO BE A GREATER POSSIBILITY...ESPECIALLY OVER WESTERN ZONES...WHERE DAYTIME INSTABILITY AIDED TSRA WILL HAVE THE BEST CHANCE OF IMPACT. SO WILL NOT ISSUE ANY FLASH FLOOD WATCH OR SPS FOR FLOODING. SHORTWAVE PIVOTS NORTH OF THE AREA AND COLD FRONT EAST BY DAYBREAK WITH DRIER WSW LOW-LEVEL FLOW ON THURSDAY. THIS SHOULD ALLOW FOR DRY AND SEASONABLY WARM CONDITIONS FOR A GOOD PART OF THE DAY...BEFORE NEXT SHORTWAVE AND SURFACE TROUGH APPROACH WITH LOW CHANCE SHOWERS LATE IN THE DAY...ESPECIALLY WEST OF NYC. && .LONG TERM (FRIDAY THRU WEDNESDAY)... NORTH ATLANTIC RIDGE REMAINS STRONG WHILE UPPER TROUGH REMAINS OVER INTERIOR NORTHEAST WITH PERIODIC SHORTWAVES ROTATING AROUND IT. ONE UPPER LOW MOVES SHEARS OUT INTO QUEBEC ON FRIDAY...WITH THE NEXT CUTOFF UPPER LOW OVER THE OHIO VALLEY/EASTERN GREAT LAKES TAKING ITS PLACE SUNDAY THROUGH TUESDAY. THIS SCENARIO WILL KEEP COLD POOL ALOFT IN PLACE JUST TO THE WEST...VORTICITY LOBES PASSING THROUGH THE REGION...A SUFFICIENTLY MOIST LOW-LEVEL SW FLOW ...AND DAYTIME HEATING AND INSTABILITY...CREATING THE CHANCE FOR AFTERNOON/EVENING SHRA/TSRA ACTIVITY THROUGH THE PERIOD. BEST CHANCE FOR WIDESPREAD RAIN SEEMS TO BE LATE MONDAY THROUGH TUESDAY WITH UPPER LOW LIFTING NORTH THROUGH THE AREA AND SURFACE LOW PRESSURE MOVING UP THE COAST. TEMPS THROUGH THE PERIOD WILL BE AT OR SLIGHTLY BELOW SEASONABLE LEVELS WITH INCREASED CLOUD COVER DURING PEAK HEATING HOURS. .MARINE... SEAS HAVE COME DOWN TO 4 FEET ACROSS THE OCEAN WATERS THIS AFTERNOON SO WILL LOWER THE SMALL CRAFT ADVISORY ON THIS ISSUANCE. SEAS AND WINDS EXPECTED TO REMAIN BELOW ADVISORY CRITERIA THROUGH THE NEXT FIVE DAYS. BOTH HOWEVER WILL BE LOCALLY HIGHER IN THE VICINITY OF ANY SHOWERS OR THUNDERSTORMS. && .AVIATION...MVFR CIGS PERSIST AT KISP AND KGON...OTHERWISE EARLY AFTERNOON CLEARING HAS TEMPORARILY BROUGHT VFR TO AREA TERMINALS. EXPECT CONDITIONS TO COME BACK DOWN TO MVFR/OCCASIONAL IFR IN SHOWERS AND THUNDERSTORMS...WITH ONE LEADING CELL MAKING A BEELINE FOR KEWR BY 2030Z...AND THEN KJFK/KLGA AFTER 21Z. LOOK FOR WIDESPREAD MVFR CONDITIONS TONIGHT IN SHOWERS AND THUNDERSTORMS THIS EVENING...ENDING FROM WEST TO EAST FROM 04Z-08Z...THEN RESIDUAL MVFR IN MIST WITH LIGHT SW AND ABUNDANT LOW LEVEL MOISTURE UNTIL AFTER DAYBREAK. CONDITIONS WILL IMPROVE TO VFR AFTER 12Z WITH DAYTIME HEATING. && .HYDROLOGY...POTENTIAL FOR ISOLATED HEAVY RAINFALL THIS EVENING AND FIRST PART OF TONIGHT WITH ACTIVITY AHEAD OF COLD FRONT. GENERAL QPF SHOULD ONLY BE ONLY 1/4 TO 1/2 INCH...BUT LOCAL 1+ AMOUNTS NOT OUT OF THE QUESTION WITH SCATTERED TSRA ACTIVITY. SEE SHORT TERM DISCUSSION FOR MORE. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...NONE. NJ...NONE. NY...NONE. MARINE...NONE. &&
