AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 342 PM EDT SUN JUL 27 2014 .SYNOPSIS... DEVELOPING SURFACE LOW PRESSURE ACROSS NEW YORK WILL TRACK INTO VERMONT ON MONDAY...RESULTING IN A WIDESPREAD MODERATE RAINFALL. A FEW EMBEDDED THUNDERSTORMS WITH LOCALIZED GUSTY WINDS WILL BE POSSIBLE OVER EASTERN VERMONT ON MONDAY AFTERNOON. TEMPERATURES WILL BE SEVERAL DEGREES BELOW NORMAL TO START THE WORK WEEK...WITH SOME SHOWERS LINGERING INTO TUESDAY AND WEDNESDAY. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... AS OF 340 PM EDT SUNDAY...WEAK SHORT WAVE ENERGY IN THE WESTERN FLW ALOFT WL QUICKLY EXIT OUR NORTHERN/CENTRAL CWA BY 03Z...AND ANY LEFTOVER SHOWERS/STORMS WL BE DISSIPATING. EXPECTING PULSE LIKE STORMS WITH LIMITED ORGANIZATION TO CONT THRU EARLY THIS EVENING. LAPS SHOWS SFC BASED CAPE VALUES BTWN 1500 AND 1800 J/KG. THIS WL PRODUCE SCATTERED ACTIVITY WITH BRIEF HEAVY RAINFALL...ISOLATED SMALL HAIL...AND VERY LOCALIZED GUSTY WINDS. WL MENTION CHC POPS FOR NORTHERN VT THRU 02Z THIS EVENING...THEN TAPER TO SCHC INTO THE OVERNIGHT HRS. STILL CANNOT COMPLETELY RULE OUT A SHOWER OR TWO...PER POSITION OF SFC BOUNDARY ACRS OUR CENTRAL ZNS...AND WEAK EMBEDDED VORTS. MEANWHILE...TWD 12Z MONDAY MOISTURE AND ENERGY FROM NORTHERN PLAINS SYSTEM WL BE APPROACHING OUR SOUTHERN CWA. WL INCREASE POPS TO LIKELY AFT 09Z MONDAY...TO SUPPORT A SLIGHTLY FASTER ARRIVAL OF THIS PRECIP. DIFFICULT TO DETERMINE OVERNIGHT LOWS WITH CLOUDS AND HIGHER SFC DWPTS...THINKING MAINLY 50S MTNS TO 60S WARMER VALLEYS. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/... AS OF 340 PM EDT SUNDAY...POTENT SYSTEM WL IMPACT OUR CWA ON MONDAY/MONDAY NIGHT...WITH A WIDESPREAD MODERATE TO LOCALIZED HEAVY RAINFALL EVENT. IN ADDITION...STILL WATCHING FOR THE POTENTIAL OF STRONG STORMS ACRS OUR EASTERN/SOUTHERN CWA ON MONDAY AFTN...AS PART OF THIS AREA GETS INTO THE WARM SECTOR. TOTAL RAINFALL AMOUNTS WL GENERAL BE BTWN 1 AND 2 INCHES BY TUESDAY WITH THE HEAVIEST AMOUNTS FROM THE DACKS TO CPV TO NORTHERN/CENTRAL VT MTNS. NOT ANTICIPATING ANY MAJOR HYDRO ISSUES...BUT COULD SEE SOME MINOR POOR DRAINAGE URBAN FLOODING IN THE HIGHER RAINFALL RATES ON MONDAY. WATER VAPOR SHOWS POTENT 5H VORT ACRS THE WESTERN GREAT LAKES...QUICKLY MOVING SE TWD THE OHIO VALLEY ATTM...WITH SOME LIGHTNING ACTIVITY ALREADY NOTED UNDER THE 5H CIRCULATION. THIS CONVECTIVE ACTIVITY AND UPSTREAM ACTION TODAY...MAKES FOR A TRICKY SFC LOW TRACK HEADING INTO MONDAY...ALONG WITH THE EXACT PLACEMENT OF A STRONG NW TO SE THERMAL BOUNDARY. AS VIGOROUS 5H VORT ROUNDS MID/UPPER LVL TROF...SYSTEM WL BECOME NEGATIVELY TILTED BY 18Z WEDS...WITH SFC LOW PRES TRACKING FROM NEAR KBGM AT 12Z MONDAY TO NORTHERN VT BY 00Z TUES. THIS TRACK PLACES OUR WESTERN CWA ON THE COOL SIDE...WHILE PARTS OF THE CENTRAL/EASTERN CWA WL BE IN THE WARM SECTOR WITH THE POTENTIAL FOR CONVECTION ON MONDAY AFTN. THINKING INITIAL SURGE OF MID WAA LIFT/MOISTURE WL DEVELOP ACRS RUTLAND/WINDSOR COUNTIES AROUND 12Z MONDAY AND LIFT INTO CENTRAL/NORTHERN VT 14Z...BEFORE BEING NORTH OF OUR CWA BY 16Z MONDAY. THIS LIFT/MOISTURE WL RESULT IN A 2 TO 4 HOUR WINDOW OF MODERATE RAINFALL WITH EMBEDDED STORMS. HOWEVER...AS SOME BREAKS DEVELOP IN THE WARM SECTOR ON MONDAY AFTN...SFC INSTABILITY IS EXPECTED TO INCREASE BTWN 800 AND 1200 J/KG...WITH 0 TO 6 KM SHEAR AROUND 30 KNOTS. THINKING SCATTERED STORMS WL DEVELOP ACRS OUR EXTREME EASTERN CWA...WITH A FEW STRONGER STORMS CAPABLE OF GUSTY WINDS AND SMALL HAIL POSSIBLE....ESPECIALLY GIVEN THE VERY STRONG DYNAMICS ALOFT. THE SYSTEM AND ASSOCIATED CONVECTION ON MONDAY WL BE DRIVEN BY THE STRONG DYNAMICS AND NOT SO MUCH THE INSTABILITY. BOTH THE GFS/NAM 850 TO 500MB RH PROGS SHOW A NICE WELL DEFINED DRY SLOT DEVELOPING ACRS OUR EASTERN CWA AT 18Z MONDAY...WHILE A BAND OF DEEP RH ASSOCIATED WITH BACKSIDE DEFORMATION EXTENDS FROM NORTHERN/CENTRAL NY INTO NORTHERN VT. THIS MOISTURE COMBINED WITH FAVORABLE NORTHWEST LVLL UPSLOPE FLW AND ASSOCIATED LIFT FROM THERMAL DRIVEN MID LVL TROWAL FEATURE WL HELP TO PRODUCE ADDITIONAL MODERATE RAINFALL ACRS THE DACKS INTO THE CPV AND MOST OF CENTRAL/NORTHERN VT ON MONDAY AFTN/EVENING. GIVEN THE TRACK OF THE CLOSED 85H AND 7H CIRCULATIONS...AND SFC LOW...EXPECT BACKSIDE DEFORMATION PRECIP TO LINGER OVERNIGHT MONDAY...BEFORE TAPERING OFF ON TUES MORNING. THINKING TOTAL QPF WL RANGE BTWN 0.25 AN 0.75" SLV/WESTERN DACKS TO 0.75 TO 1.75" EASTERN DACKS/CPV AND NORTHERN VT....WITH AMOUNTS BTWN 0.50 AND 1.0" ACRS SOUTHERN/CENTRAL VT...WITH SOME LOCALIZED HIGHER AMOUNTS AROUND 2.0" POSSIBLE DUE TO CONVECTION AND TRRN. EXPECTING SOME SHARP RISES ON SMALLER STREAMS/RIVERS...BUT GIVEN RECENT DRY SPELL NO MAJOR HYDRO ISSUES ANTICIPATED ATTM. VERY INTERESTING TEMP PROFILE ON MONDAY WITH NORTHERLY WINDS DOWN THE CPV/SLV AND LVLL CAA/CLOUDS...TEMPS WL STRUGGLE IN THE UPPER 50S DACKS TO L/M60S CPV/SLV AND MID 70S LWR CT RIVER VALLEY NEAR VSF. THE MTNS OF VT WL HOLD IN THE U50S TO LOWER 60S ON MONDAY WITH LOWER 70S POSSIBLE IN THE NEK VALLEYS. TUESDAY-TUESDAY NIGHT...MID/UPPER LVL CLOSED CIRCULATION LIFTS INTO EASTERN CANADA WITH CYCLONIC NW FLW ACRS OUR CWA. BEST 850 TO 500MB MOISTURE LIFTS NORTH OF OUR CWA BY 12Z TUES...BUT GIVEN AMOUNT OF ENERGY IN THE FLW ALOFT AND SOME SFC HEATING ON TUES AFTN...CANNOT RULE OUT THE POTENTIAL FOR SOME SCATTERED SHOWERS TO DEVELOP IN THE AFTN...ESPECIALLY WITH PLENTY OF LEFTOVER BL MOISTURE. THIS ACTIVITY WL DECREASE BY TUES EVENING...WITH CHILLY NORTHWEST WINDS. TUES/TUES NIGHT WL FEEL A BIT LIKE FALL WITH TEMPS ONLY WARMING INTO THE U50S/L60S MTNS TO NEAR 70F WARMER VALLEYS...ASSOCIATED WITH PROGGED 85H TEMPS ONLY BTWN 6-8C. WINDS/CLOUDS AND PLENTY OF LEFTOVER BL RH WL KEEP TEMPS FROM COMPLETELY BOTTOMING OUT ON TUES NIGHT...THINKING MAINLY 40S MTNS TO 50S VALLEYS. && .LONG TERM /WEDNESDAY THROUGH SUNDAY/...

DESPITE THE PRESENCE OF LARGE UPPER TROUGH OVER THE REGION...EXPECT MUCH OF THE TIME TO BE DRY. SHORTWAVES MOVING THROUGH THE MEAN TROUGH DIFFICULT TO TIME THIS FAR OUT...BUT LATEST GUIDANCE SUGGESTS STRONGEST DISTURBANCE WILL MOVE ACROSS THE AREA THURSDAY. OTHERWISE...CHANCES FOR PRECIPITATION LARGELY DIURNALLY DRIVEN...WITH BEST CHANCES DURING THE AFTERNOON HOURS AND MAINLY DRY CONDITIONS ANTICIPATED EACH NIGHT AND EARLY MORNING. BELOW NORMAL TEMPS EXPECTED THROUGH MIDWEEK. 850 MB TEMPS PROGGED TO TO BE AROUND 10-11C WED/THU THEN MODERATE TO 12-13C BY THE WEEKEND.
