NWS Albany, NY wrote its last area forecast discussion before the first event at Jul 18, 2:53 PM EST, 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ALBANY, NY 353 PM EDT SUN JUL 18 2004 .SHORT TERM (TONIGHT AND MONDAY)... OUR ATTENTION HERE IS FOCUSED SQUARELY ON FLOOD POTENTIAL. BY WAY OF REVIEW...MIDNIGHT SHIFT ISSUED FLOOD WATCH FOR NORTH HALF OF CWA BASED ON EXPECTED SLOW MOVING THUNDERSTORMS THIS AFTERNOON AND EARLY EVENING. THE DAY SHIFT EXPANDED WATCH TO INCLUDE THE ENTIRE CWA AND LENGTHENED UNTIL NOON MONDAY BASED ON 06Z RUN OF GFS CONTINUING TO SHOW FAIRLY HIGH QPF ACROSS THE REGION. HERE/S WE STAND NOW...SLOW MOVING THUNDERSTORMS HAVE INDEED DEVELOPED ACROSS THE NORTHERN TIER OF THE CWA...WITH SOME STORMS PRODUCING SOAKING RAINS...ALTHOUGH NOT REACHING FFW CRITERIA /ALTHOUGH BTV DID ISSUE A FLASH FLOOD WARNING FOR ESSEX COUNTY EARLIER THIS AFTERNOON/. 12Z RUNS OF THE GFS AND ETA WOULD NOT SUPPORT CONTINUATION OF THE WATCH WITH THE EXCEPTION OF LETTING AFTERNOON CONVECTION RUN ITS COURSE INTO THE EVENING. HOWEVER...WE WILL MAINTAIN THE WATCH CWA-WIDE THROUGH NOON MONDAY. HERE/S WHY... HEAVY RAIN HAS BEEN FALLING THIS AFTERNOON ACROSS EASTERN PA/WESTERN NJ IN AREA OF STRONG UPPER LEVEL DIVERGENCE ASSOCIATED WITH ANOMALOUSLY STRONG JET HUGGING THE COAST. ETA DEPICTS THIS STRONG UPPER LEVEL DIVERGENCE TO WORK INTO THE SOUTHERN CWA TONIGHT AS JET TRACKS UP THE COAST...THEN WEAKEN AS IT MOVES INTO NORTHERN. ETA CONTINUES TO FEATURE FAIRLY IMPRESSIVE TROWAL SIGNATURE SUGGESTIVE OF OCCLUSION DYNAMICS...AND POTENTIAL FOR EMBEDDED TSRAS. TROWAL TRACKS ACROSS THE CWA BETWEEN 06-12Z...ALTHOUGH BASED ON RADAR TRENDS...THIS LOOKS TO BE SLOW. ETA CONTINUES TO FORECAST EAST/SOUTHEAST 850MB WINDS ON THE ORDER OF 25-30 KNOTS. GFS IS SLIGHTLY LOWER ON THE SPEEDS...ALTHOUGH A CHECK OF OKX/DIX VWPS SUGGESTS ETA WINDS CURRENTLY RIGHT ON. WITH PWS CLIMBING TO AROUND 1.6 INCHES THIS EVENING...THINK ABOVE MENTIONED FORCING MECHANISMS WILL BE ABLE TO WRING OUT SOME LOCALLY HEAVY RAINFALL. BASED ON THESE FACTORS WE WILL CONTINUE THE WATCH ACROSS THE ENTIRE CWA UNTIL NOON MONDAY ALTHOUGH THREAT IS NOT EQUALLY DISTRIBUTED ACROSS THE CWA. IN THE NORTH...THREAT MAINLY THROUGH THIS EVENING WITH SLOW MOVING THUNDERSTORMS WHERE FFG VALUES ARE LOWEST. PRIMARY THREAT WILL SHIFT SOUTH DURING THE NIGHT AS EASTERLY FLOW COMMENCES AND IMPINGES ON EAST FACING SLOPES. THIS WOULD PUT THE THREAT IN AREAS SUCH AS THE CATSKILLS. PLAN ON CATEGORICAL POPS ENTIRE CWA TONIGHT...EXCEPT IN THE NORTH WHERE NUMEROUS/SCATTERED WORDING TO START THEN LIKELY POPS AS BEST FORCING TAKES MOST OF THE NIGHT TO WORK NORTH. SURFACE LOW WILL LOOSE ITS DEFINITION MONDAY...BUT TROUGH WILL LINGER ACROSS THE REGION. DEPENDING ON CLOUD COVER...WOULD EXPECT SOME TSRAS TO DEVELOP DURING THE AFTERNOON WITHIN THE TROUGH. DEW POINTS WILL BE QUITE HIGH TOMORROW...NEAR 70...SO ANY BREAKS IN THE CLOUDS WOULD ALLOW TEMPS TO CLIMB NEAR 80...YIELDING CAPES TO 2000 J/KG. ALLOWING FOR LIKELY POPS TO CLEAR THE NORTHERN CWA IN THE MORNING WILL CARRY CHANCE SHRA/TSRA IN THE AFTERNOON. && .LONG TERM (MONDAY NIGHT THROUGH SUNDAY)... WILL LINGER CHANCE TSRA/SHRA THROUGH TUESDAY NIGHT AS REGION REMAINS UNDER INFLUENCE OF TROUGHS...AT SURFACE AND ALOFT. WILL KEEP IT DRY FOR WEDNESDAY AND MOST OF THURSDAY BEFORE SHOWERS ONCE AGAIN ENTER THE PICTURE. RIGHT NOW...NEXT WEEKEND NOT LOOKING TOO GOOD AS SURFACE FRONT HANGS UP IN VICINITY OF CWA. && .AVIATION...VFR CONDITIONS FOR THE NRN HALF OF THE HUDSON RIVER VALLEY WILL LOWER TO MVFR/IFR CONDITIONS IN ISOLD/SCT SHRA/TSRA...ESPECIALLY FOR KGFL INTO THE EARLY EVENING. FOR KALB AND KPOU CONDITIONS AT THE VFR/MVFR LEVELS WILL DROP DOWN TO MVFR/IFR WITH SHRAS BR/HZ IN MUGGY AIR MASS AHEAD INITIAL SHORT WAVE/VORT MAX. COASTAL LOW OVERNIGHT WILL BRING ANOTHER SHOT OF RAINFALL AFTER MIDNIGHT WHICH MAY BRIEFLY LOWER CONDITIONS TO IFR/MVFR LEVELS IN THE 03Z TO 12Z TIME FRAME. && .HYDROLOGY... FLOOD WATCH FOR FLASH FLOODING IN EFFECT UNTIL NOON MONDAY. FFG VALUES ARE RATHER LOW FOR THIS TIME OF THE YEAR...WITH MANY AREAS HAVING 6 HOUR VALUES AT OR BELOW 2.5 INCHES AND 12 HOUR VALUES BELOW 3. CURRENT RADAR LOOP SHOWS CELLS ARE MOVING QUITE SLOWLY SO LOCALIZED FLOODING OVER SMALL AREAS COULD BE A PROBLEM THIS AFTERNOON AND EVENING. AS THE STEADY PRECIP MOVES IN FROM THE SOUTH THE SITUATION COULD TURN INTO MORE OF A WIDESPREAD RAIN EVENT ALTHOUGH AT THIS TIME WE ARE NOT EXPECTING RIVER FLOODING TO MATERIALIZE EXCEPT POSSIBLY ON THE MOHAWK RIVER AT UTICA...AND THAT WILL DEPEND A GREAT DEAL ON THE MOVEMENT OF THE STORMS CURRENTLY IN THAT AREA. MAIN THREAT WOULD BE FOR SMALL STREAMS AND CREEKS THAT ARE RUNNING HIGH FROM SCT CONVECTION/WET WEATHER OVER THE PAST WEEK. && .ALY WATCHES/WARNINGS/ADVISORIES...
