Area forecast discussion, Aug 25, 8:38 PM EST, 1 hour 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 938 PM EDT FRI AUG 25 2006 .SHORT TERM /THROUGH FRIDAY NIGHT/... SCATTERED STRONG TO POSSIBLY SEVERE TSRA FORMING IN THE SHALLOW COOL AIR TO THE NORTH OF A STATIONARY FRONT EXTENDING FROM THE NW PENN MTNS...SE TO BETWEEN KHGR AND KTHV. TRIGGERING MECHANISM WAS AN UPPER SPEED MAX (85 KTS AT 300 HPA) THE STRONGEST STORM BETWEEN KBFD AND KJHW HAS SHOWN A FAIRLY PERSISTENT INBOUND/OUTBOUND VELOCITY COUPLET AT LOWER ELEVATION SCANS FROM KBUF AND KCCX RADARS. 0-3 KM HELICITY VALUES IN THE PATH OF THIS STORM WERE IN THE 300-400 M2/S2 RANGE...SUPPORTING CONTINUED UPDRAFT ORGANIZATION AND ROTATION AS IT HEADS ACROSS OUR NRN ZONES DURING THE NEXT FEW HOURS. MAIN CHANGE TO THE PRIOR ZONES WAS TO RAISE POPS OVERNIGHT BY ABOUT 20 PERCENT ACROSS THE NRN AND EASTERN PARTS OF THE CWA. && .PREV DISCUSSION... /ISSUED 257 PM EDT FRI AUG 25 2006/ SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/... MOST OF THE AREA HAS CLEARED OR SCATTERED OUT AND IS WARMING NICELY. BUT SO FAR LITTLE IN THE WAY OF CONVECTION TO SHOW FOR THE SUNSHINE. WEAK FRONTAL BOUNDARY IS VERY HARD TO FIND BUT LOOKS TO BE THRU CENTRAL PA. MAIN FEATURE IT DELINEATES IS AN INCREASE IN DEWPOINTS SLIDING INTO THE SOUTHERN HALF OF THE STATE. MODELS HINT THAT THE ASSOCIATED FRONTAL TROF WILL HANG KIND OF TOUGH OVER THE NEXT 12-18 HOURS BEFORE FLATTENING INTO A BROAD SOUTHERLY FLOW LATER SATURDAY AND SUNDAY. THIS NORMALLY MEANS MODELS ARE HINTING AT A COOL AIR DAMMING SCENARIO BUT FCST LI FIELDS SEEM TO SUGGEST THAT THE FRONT WILL SLIDE UP TO AROUND THE NY-PA BORDER IN TIME. MODELS AGREE THAT WE WILL CONTINUE TO SEE AN INCREASE IN MOISTURE WITH PRECIP WATERS APPROACHING 2 INCHES BY LATER SAT. SREF SHOWS THIS TO BE 1-2 STD DEV ABOVE NORMAL. WITH STEADILY INCREASING SOUTHERLY FLOW...LOOKS LIKE THE THREAT OF SHOWERS WILL CONTINUE THROUGH AT LEAST THE FIRST HALF OF THE WEEKEND. WITH TOMORROW PROBABLY STAYING KIND OF CLOUDY...THINK SIG INSTABILITY MIGHT BE HARD TO COME BY. HOWEVER...SHEAR PROFILES SHOULD BE IMPRESSIVE WITH SOUTHERLY LOW LEVEL FLOW TRANSITIONING TO NW FLOW ALOFT. IF WE CAN MANAGE ANY SUNSHINE AND DEVELOP SOME CAPE...THE SEVERE THREAT COULD BE IMPRESSIVE. AS FOR NOW WE ARE SLIGHT RISKED IN THE SEVERE OUTLOOK. THIS LOOKS REASONABLE. LONG TERM /SUNDAY THROUGH FRIDAY/... LONGWAVE PATTERN GENERALLY AMPLIFYING THROUGH THE PERIOD WITH BROAD MOIST SOUTHWEST FLOW EARLY TRANSITIONING TO MORE RIDGING BY THE END OF NEXT WEEK AS LARGE POSITIVE HEIGHT ANOMALIES BUILD ACROSS THE CENTRAL UNITED STATES DURING THE MIDDLE TO LATTER PORTION OF NEXT WEEK. FOR THE DAILY DETAILS...THIS TRANSLATES INTO CONTINUED SHOWER AND THUNDERSTORM CHANCES EARLY TO MID WEEK BEFORE THE UPPER RIDGE AXIS BUILDS INTO THE OHIO VALLEY AND DRIES US OUT FOR THE LATTER PORTION OF THE WEEK. TEMPS REMAIN SEASONABLE THROUGH MID WEEK BEFORE NORTHWEST FLOW BRINGS A SLIGHTLY ANOMALOUSLY COOL AIR MASS BY THU AHEAD OF BUILDING UPPER RIDGE. MREFS INDICATE POTENTIAL FOR WARMING AND ABOVE NORMAL TEMPERATURES NEXT WEEKEND (LABOR DAY) AS 925 MB TEMP ANOMALIES INCREASE TO 1 TO 2 S.D. ABOVE NORMAL SAT. AVIATION... WEAK BOUNDARY CONTINUES TO FLOAT AROUND CENTRAL PA. MESO ANAL SHOWS THE FEATURE TO BE VERY HARD TO FIND...BUT PROBABLY EXTENDS FROM JUST SOUTH OF ERI...TO NEAR AOO TO THE LOWER SUSQ VALLEY. MAIN EFFECT WILL BE TO PROVIDE A FOCUS FOR CONVECTION AS MARGINALLY UNSTABLE AIRMASS SUCCUMBS TO THE WEAK LOW LEVEL CONVERGENCE ALLOWING SOME SHOWERS TO EVENTUALLY POP. OTHER THAN IN THE SHOWERS AND STORMS...THE BULK OF THE REST OF THE DAY AND EVENING WILL BE VFR. SIMILAR TO LAST COUPLE OF NIGHTS...WILL PROBABLY SEE VIS DETERIORATE OVERNIGHT WITH SOME FOG AND HAZE. AREAS NEAR THE RIVERS....THOSE THAT SEE RAIN WILL STAND THE BEST CHANCE OF DROPPING TO IFR LATER TONIGHT AND FOR A FEW HOURS SURROUNDING SUNRISE. MIGHT BE TOUGHER TO CLEAR OUT THE FOG AND HAZE TOMORROW AS GUIDANCE INCREASINGLY POINTS TO A RATHER CLOUDY SHOWERY DAY. THIS WOULD LEAVE MUCH OF THE REGION VULNERABLE TO STAYING IN THE 4-5 MI RANGE WITH LINGERING HAZE AND SCATTERED CONVECTION. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...LAMBERT
