AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 1110 AM EDT FRI JUL 23 2004 .UPDATE (THIS AFTERNOON)... COLD FRONT IS CURRENTLY ALONG A LINE FROM JUST WEST OF SYR TO JUST WEST OF ELM MOVING STEADILY EAST. WITH BANDS OF HEAVY RAIN CONTINUING AHEAD OF THE FRONT WILL CONTINUE THE FLASH FLOOD WATCH THROUGH THIS AFTERNOON FOR THE CENTRAL COUNTIES... AND INTO THIS EVENING ACROSS THE SOUTHEAST. GETTING RADAR ESTIMATES OF 4 TO 4.5 INCHES OVER EASTERN SULLIVAN COUNTY LATE THIS MORNING. ELSEWHERE JUST SOME LOCALIZED 1 TO 2 INCH AMOUNTS. HOWEVER WITH SOME BREAKS DEVELOPING IN THE OVERCAST ACROSS NORTH CENTRAL PA WILL HAVE TO WATCH THE LINE OF SHOWERS AND THUNDERSTORMS ASSOCIATED WITH THE FRONT LATER THIS AFTERNOON FOR ADDITIONAL HEAVY RAINS. LACK OF SHEAR SHOULD PRECLUDE ANY ORGANIZED SEVERE RISK. BASED ON THIS... HAVE UPDATED THE ZONES TO REFINE THE TIMING OF THE RAIN A BIT. HAVE ALSO MENTIONED TURNING COOLER AND LESS HUMID TONIGHT ACROSS NY. .PREVIOUS SHORT TERM (TODAY THRU SATURDAY)... TODAY...A COLD FRONT CURRENTLY EXTENDS FROM SRN QUEBEC THROUGH NRN OHIO AND INTO CENTRAL ILLINOIS. THE FRONT IS NEARLY PARALLEL TO THE UPPER LEVEL FLOW...SO IT WILL BE SLOW TO MOVE THROUGH THE AREA... REACHING NW ZONES AROUND MIDDAY AND CENTRAL ZONES MID TO LATE AFTERNOON. AHEAD OF THE FRONT...SHOWERS AND TSTORMS WILL CONTINUE AS SHORTWAVE ENERGY MOVES THROUGH. THE COVERAGE/INTENSITY OF ANY STORMS WILL DEPEND ON THE AMOUNT OF HEATING. ETA BUFKIT SOUNDINGS ARE SHOWING CAPES NEAR 2000 AROUND MIDDAY SOUTH OF THE FRONT...BUT THAT IS WITH TEMPS IN THE LOWER 80S AND DEWPOINTS IN THE LOWER 70S. THERE IS A CHANCE WE COULD SEE A LITTLE SUN THIS MORNING...WHICH WOULD GET TEMPS INTO THE UPPER 70S...BUT THE ETA CAPES ARE PROBABLY A WORST CASE SCENARIO. IN ANY EVENT...SHOULD STORMS FORM...WET BULB ZERO LEVELS ARE LOW AND THERE IS A MID-LEVEL DRY LAYER...SO HAIL AND GUSTY WINDS ARE POSSIBLE...NOT TO MENTION HEAVY RAIN. WINDS ALOFT WILL CONTINUE TO BE WEAK WITH PWS OF 1.75 TO 2...SO WILL KEEP FLASH FLOOD WATCH GOING FOR SE HALF OF THE AREA TODAY. TONIGHT...HIGH PRESSURE BUILDS INTO SE CANADA WHICH SHOULD CLEAR OUT THE NW PORTION OF THE AREA. THE COLD FRONT MOVES THROUGH SE ZONES DURING THE EVENING...ONLY MOVING AS FAR AS THE COASTLINE BY SAT MORNING. WILL KEEP LIKELY POPS ACROSS FAR SE ZONES AND CHC POPS OVER CENTRAL ZONES. WITH COLD AIR MOVING IN OVER WET GROUND...FOG SHOULD BE FAIRLY WIDESPREAD...SO WILL MENTION IN ZONES. SATURDAY...A TROUGH DIGGING INTO THE CENTRAL U.S. KEEPS THE UPPER FLOW SOUTHWEST OVER THE NE U.S.. SHORTWAVE ENERGY MOVING THROUGH THE SW FLOW ALOFT COMBINED WITH CONVERGENT LOW LEVEL FLOW SHOULD KEEP A CHANCE OF SHOWERS GOING ACROSS SE ZONES...WITH NW ZONES REMAINING DRY. && .LONG TERM (SUNDAY-THURSDAY)... THE PATTERN DOESNT CHANGE MUCH THROUGH THE MIDDLE OF NEXT WEEK... WITH SOUTHWEST FLOW ALOFT...HIGH PRESSURE EXTENDING FROM THE MIDWEST INTO SE CANADA...AND A FRONTAL BOUNDARY OVER THE MID-ATLANTIC REGION. SHORTWAVES IN THE UPPER FLOW WILL BRING A CHC OF SHOWERS/TSTORMS EVERY DAY...ESPECIALLY OVER SE ZONES. .AVIATION... DUE TO WIDESPREAD HAZE AND MIST, MVFR CONDITIONS WILL PERSIST THROUGH THE EARLY MORNING PERIOD DUE TO VSBY RESTRICTIONS. A COLD FRONT MOVING THROUGH THE REGION WILL ALSO BRING NUMEROUS SHOWERS AND THUNDERSTORMS TO THE REGION. THIS WILL CONTINUE THE MVFR CONDITIONS THROUGH MIDDAY DUE TO BOTH VSBY/CIGS RESTRICTIONS. AFTER 18Z TODAY, THE ACTIVITY WILL DIMINISH AND CONDITIONS SHOULD IMPROVE TO VFR BUT CIGS WILL PROBABLY BE IN THE 040/060 RANGE. SOME LIGHT FOG CAN BE EXPECTED AGAIN AFTER MIDNIGHT TONIGHT BRINGING MVFR VSBY RESTRICTIONS AGAIN. && .BGM WATCHES/WARNINGS/ADVISORIES... NY...FLOOD WATCH THROUGH THIS AFTERNOON ACROSS THE SE HALF.
