AREA FORECAST DISCUSSION...UPDATED... NATIONAL WEATHER SERVICE UPTON NY 200 PM EDT MON JUN 6 2005 .18Z UPDATE...UPDATES FORTHCOMING FOR SVR TSTM WATCH 416 (EXPIRES 07/02Z) FOR NJ/NY PORTIONS OF CWA (EXCEPT SUFFOLK CO NY AND CT COUNTIES). 18Z RAOB SHOULD BE AVBL SHORTLY... && .14Z UPDATE... AFD UPDATE FOR NEAR TERM (INCLUDING HYDROLOGY/MARINE/AVIATION) CONCERNS ONLY. NO CHANGES TO SHORT/LONG TERM DISCUSSIONS AS YET. WILL ADDRESS THOSE TIME PERIODS IN THIS AFD THIS AFTERNOON. && .NEAR TERM (THROUGH TONIGHT)... BACKDOOR FRONT CREEPING TOWARD NE CWA...WINDS HAVE GONE 040 AT KIJD AS OF 13Z AND ARE NE AT SEVERAL MESONET SITES IN NEW LONDON CO. BIG QUESTON IS JUST HOW MUCH FARTHER S WIL FRONT GET...MAXTS AND CLOUD COVER WOULD BE MOST IN QUESTION. BIGGER PROBLEM DU JOUR IS SEVERE WX THREAT. MSAS SFC-BASED LIUS ALREADY AOB 0C WESTERN 1/2 CWA (WHICH NOT SO COINCIDENTALLY IS WHERE SPCS SLIGHT RISK IS)...WITH TDS INTO M-U60S AND TEMPS ROCKETING UPWARD. LEE SIDE TROF IN PLACE AND ALSO LOOKS LIKE ANOTHER WEAK SFC TROF ACROSS CATSKILLS AND HUDSON VALLEY...BOTH COULD BE PRIME LIFTING MECHANISMS FOR LATER IN THE DAY AS ATMOS CONTINUES TO COOK. THINK THAT LEE SIDE TROF WOULD BE PRIMARY FOCUS...BUT WITH THIS JUICY ATMOS...ALL WILL BE MONITORED. WBZ HEIGHTS ON 12Z OKX SOUNDING JUST OVER 11K FT...BUT MODEL SOUNDINGS DROP THEM DURING THE AFTERNOON A BIT AS ONE MIGHT EXPECT WITH APPROACH OF MID LEVEL S/WV AND TROF. SO...HAIL MAY BE A THREAT AS WELL AS WINDS (PBZ LSR FROM 13Z HAD A SVR HAIL REPORT). PWS NEAR 1.50 SO WILL ALSO HAVE TO WATCH OUT FOR SOME HEAVY RAINERS. SVR TSTM WATCH 413 ISSUED WITHIN PAST HOUR TO OUR N AND W...A FURTHER HARBINGER OF THINGS TO COME. ENHANCED WORDING ALREADY IN TEXT PRODUCTS AND ONLY MINOR ADJUSTMENTS TO GRID/TEXT PRODUCTS ANTICIPATED AT THIS TIME. WILL ADJUST TEMP FIELDS AS NEEDED BASED ON LATEST OBS TRENDS. UPDATED SPSOKX REGARDING SEVERE WX POTENTIAL ISSUED BY 1500Z. && .SHORT TERM (TUESDAY THROUGH WEDNESDAY)... WITH THE SHORTWAVE PASSING THROUGH THE AREA WILL CONTINUE WITH A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS INTO THE MORNING TUESDAY. THEN WILL LEAVE DRY AS THE WEAKENING COLD FRONT APPROACHES AND PASSES THROUGH THE AREA 04Z TO 08Z WEDNESDAY. BEST DYNAMICS WITH THE FRONT ARE TO THE NORTH. RIDING BUILDS INTO THE AREA FROM THE NORTHWEST WEDNESDAY. SURFACE WINDS SHIFT TO THE SOUTH TO SOUTHWEST AND WARM AIRMASS RETURNS. WILL BE SLIGHTLY LESS HUMID BUT DAYTIME HIGHS WILL ONCE AGAIN BE IN THE 80S TO NEAR 90 SO WILL RAISE TEMPERATURES CONSIDERABLY TOWARD THE MET NUMBERS. && .LONG TERM (WEDNESDAY NIGHT THROUGH SUNDAY)... SUMMER PATTERN CONTINUES THROUGH THE EXTENDED FORECAST PERIOD...WITH A MEAN RIDGE OVER THE NORTHEAST. ATMOSPHERIC FLOW REMAINS WEST OR SOUTHWEST...KEEPING US AT OR ON THE WARM SIDE OF NORMAL. WELL BE DRY WED AND THU...BUT COULD SEE SOME SHOWERS OR THUNDERSTORMS TOWARD THE END OF THE WEEK AS ANOTHER FRONT APPROACHES FROM THE WEST. && .AVIATION... SOUTHERLY FLOW CONTINUES TODAY AHEAD OF A TROUGH APPROACHING FROM THE WEST. VSBYS WILL LIKELY BE VFR FOR THE MOST PART BUT HAZY ATMOSPHERE WILL RESTRICT TO MVFR CONDITIONS AT TIMES...ESPECIALLY WHEN SUN ELEVATIONS ARE FAIRLY LOW. CIGS WILL BE VFR TODAY AND THIS EVENING OUTSIDE OF ANY CONVECTION...LOWERING TO IFR OR LOWER AS SOME STRATUS AND FOG MOVE IN FROM THE SOUTH LATE AT NIGHT. OTHERWISE... DEWPOINTS ALREADY IN THE MID-UPPER 60S WILL WORK IN CONCERT WITH TEMPERATURES RISING WELL INTO THE 80S THIS AFTERNOON TO CREATE AN INCREASINGLY UNSTABLE AIRMASS ACROSS THE LOCAL REGION...ESPECIALLY OVER THE WESTERN 1/3 WHERE CAPE VALUES ARE LIKELY TO REACH 2000 J/KG BY LATE IN THE DAY. THUNDERSTORMS WILL LIKELY FORM IN SHORT LINES AND SHOULD REACH TO JUST WEST OF THE LOCAL REGION BY MID TO LATE AFTERNOON. ALSO LOOKING AT SOME 30 TO 35 KT LOW LEVEL WINDS THIS AFTERNOON. ALL THIS SHOULD PRESENT A GOOD CHANCE OF STRONG TO LOCALLY SEVERE THUNDERSTORMS AROUND THE TERMINALS LATER TODAY INTO THIS EVENING...ESPECIALLY WESTERN TERMINALS. SPC HAS THIS AREA OF THE CWA UNDER A SLIGHT RISK OF SEVERE LATER TODAY. LOST OF HEATING WITH SUNSET SHOULD RAPIDLY DECREASE THIS THREAT. && .MARINE... OUTSIDE OF ANY CONVECTION TODAY...SEAS AND NORMAL GRADIENT WINDS SHOULD NOT PRESENT ANY PROBLEMS. STRONG TO LOCALLY SEVERE CONVECTION LATE TODAY WILL PRESENT A HAZARDOUS TO MARINERS AND WILL BE MONITORED CLOSELY. A TIGHTENING PRESSURE GRADIENT AND A SOUTHERLY FETCH WILL INCREASE SEAS TO JUST AROUND SMALL CRAFT ADVISORY LEVELS LATE TONIGHT AND TUESDAY BUT WILL HOLD OFF AT THIS TIME IN POSTING THE ADVISORY. WILL REEXAMINE THIS WITH NEW GUIDANCE AND DECIDE ON THIS WITH THE AFTERNOON PACKAGE. THINGS QUIET DOWN AGAIN FOR THE REMAINDER OF THE WEEK AS A WEAKER GRADIENT COMES INTO PLAY. && .HYDROLOGY... THUNDERSTORM RAINFALL AMOUNTS OF A QUARTER TO A HALF INCH WILL BE LIKELY...WITH LOCALLY 1-2 ESPECIALLY WITH STORMS ACROSS THE LOWER HUDSON VALLEY...NE NJ...NYC...SW CT INTO WESTERN LI.
