Area forecast discussion, Jul 4, 11:00 AM EDT, 1 hour 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 1100 AM EDT MON JUL 4 2011 .SYNOPSIS... HUMID WITH FRONT AND ASSOCIATED CLUSTERS OF THUNDERSTORMS...REMAIN IN VICINITY INTO TONIGHT...THEN MAINLY SOUTH TUESDAY. HIGH PRESSURE TUESDAY NIGHT THROUGH WEDNESDAY. NEXT FRONT PASSES THURSDAY. && .NEAR TERM /THROUGH TONIGHT/... FRONT STILL FROM NEAR PIT-CMH-DAY-IND...IN NO HURRY MOVING SOUTH. TALE OF 2 REGIMES...FIGURING NORTHERN COUNTIES CLOSER TO THE FRONT...AND HAVE THE 500 MB SUPPORT WITH VORT MAX MOVG EAST THRU 21Z TO 00Z TUESDAY. ALSO...A BIT MORE SHEAR IN WINDS ALOFT. HOWEVER...FIGURING ON LESS SUNSHINE AND LESS SURFACE DRIVEN CAPE. MEANWHILE...FURTHER SOUTH...INSTABILITY DRIVEN BY SURFACE BASED CAPE. NEW CELLS COULD EVEN DEVELOP AHEAD...EAST...OF THE COMPLEX MOVING INTO SOUTHEASTERN KY AT 15Z. EQUILIBRIUM LEVEL 35 TO 40 THSD FT...AND PRECIPITABLE WATER NEARING 2 INCHES. SO ANY CELL CAN HAVE HIGH DBZ RETURNS ON 88D AND THUS A DOWNPOUR. OUR SOUTHERN COUNTIES ARE THE DRIEST...MOST CAN HANDLE 2.5 INCHES OF RAIN. STILL WILL HAVE TO MONITOR ANY TRAINING. RADAR RAIN ESTIMATES WERE OVERESTIMATING LAST NIGHT. OVERALL...LKLY POPS EXPANDED A BIT NORTH THIS AFTERNOON...TO COVER THE NORTHERN SUPPORT. BUT STILL THINKING THE TALLER STORMS WILL BE SOUTH. MAXIMUM TEMPERATURES ARE TOUGH WITH THE AFTERNOON CONVECTION AND CLOUDS. TRIED TO BRING MAX DOWN A DEG OR 2 IN HTS-CRW VCNTY. THINKING A LOT OF HAZE AND MUGGY AIR AROUND OUTSIDE OF ANY LINGERING CONVECTION THIS EVENING. && .SHORT TERM /TUESDAY THROUGH THURSDAY NIGHT/... SOUTHERN EDGE OF THE WESTERLIES WITH WEST TO NORTHWEST FLOW ALOFT CONTINUES ACROSS OUR AREA THIS PERIOD. MODELS CONTINUE TO NOT ONLY HAVE PROBLEMS WITH MCS ACTIVITY ALONG THE EAST TO WEST FRONTAL BOUNDARY SOMEWHERE ACROSS OUR REGION THIS PERIOD...BUT ALSO IN IDENTIFYING WEAK SHORT WAVES EMBEDDED IN THE WEST TO NORTHWEST FLOW ALOFT. AT THIS TIME FRAME...ONE MUST PLAY THE SYNOPTIC FEATURES...WHICH ARE WEAK. ON TUESDAY...MODELS IDENTIFY A SHORT WAVE DROPPING SOUTHEAST ACROSS THE OHIO VALLEY...THOUGH THERE ARE DIFFERENCES IN JUST WHERE THE SURFACE FRONT WILL BE TO FOCUS CONVECTION. LOOKS LIKE MODEL CONSENSUS HAS AT LEAST THE DEEPER MOISTURE SUPPRESSED INTO OUR SOUTHERN ZONES...AND WILL USE THIS TO PLACE THE SUPPORT FOR SIGNIFICANT CONVECTION...RATHER THAN THE SURFACE FRONT ITSELF WHICH WILL LIKELY BE ACROSS NORTHERN SECTIONS. THUS...MOST OF THE POPS WILL BE SOUTH OF THE I64 CORRIDOR TUESDAY. TEMPS WILL BE NEAR NORMAL...MAINLY DUE DUE TO CLOUDS. SHORT WAVE MOVES PAST US WEDNESDAY WHILE THE FRONT WILL LIKELY DISSIPATE IN PLACE. GOING MOSTLY DRY WEDNESDAY WITH ONLY VERY LOW POPS FAR SOUTHEAST DUE TO LINGERING MOISTURE. MODELS HAVE ORGANIZED COLD FRONT CROSSING THE AREA THURSDAY... PRECEDED BY SCATTERED SHOWERS AND THUNDERSTORMS WEDNESDAY NIGHT AND THURSDAY. AGAIN...TEMPS NEAR NORMAL WITH ALL THE CLOUDS AND INCREASING SHOWERS. && .LONG TERM /FRIDAY THROUGH SUNDAY/... DECREASED POPS TO SLIGHT CHANCE BEHIND THE FRONT THURSDAY NIGHT AND EARLY FRIDAY. HAVE NO POPS/WX FOR THE REST OF NEXT WEEKEND. WENT WITH HPC TEMPERATURES GUIDANCE THROUGH THE PERIOD. && .AVIATION /15Z MONDAY THROUGH FRIDAY/... VERY MOIST ATMOSPHERE...WITH HOLES IN THE CLOUDS...ALLOWED FOR VALLEY FOG TO DEVELOP IN THE NORTHERN PART OF THE AREA. THIS WILL QUICKLY IMPROVE 12Z-14Z. HOWEVER...COMPLICATED FORECAST BECAUSE OF CLUSTERS OF INTERACTING THUNDERSTORMS EXPECTED FOR MOST OF THE AREA TODAY AS WAVES MOVE ALONG A SLOWLY SAGGING FRONT. BEST CHANCES SOUTH OF A KPKB-KCKB LINE. LEFTOVER CONVECTION MAY LINGER INTO THIS EVENING SOUTH OF KCRW-KHTS LINE. AS CLEARING OCCURS FROM THE NORTH TONIGHT...AND WITH TRAPPED LOW LEVEL MOISTURE FROM RAINFALL FROM TODAY...IT WILL BE A GOOD FOG NIGHT AREAWIDE WITH IFR TO LIFR FOR MOST VALLEYS 06Z-12Z TUESDAY. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z TUESDAY... FORECAST CONFIDENCE: MEDIUM. ALTERNATE SCENARIOS: UNCERTAINTY TO PLACEMENT OF THUNDERSTORMS. GENERALLY ONLY EXPECTING MVFR WITH STORMS...BUT DIRECTLY UNDER HEAVIER CELLS COULD HAVE IFR AND GUSTY WINDS. EXPERIMENTAL TABLE OF FLIGHT CATEGORY OBJECTIVELY SHOWS CONSISTENCY OF WFO FORECAST TO AVAILABLE MODEL INFORMATION: H = HIGH: TAF CONSISTENT WITH ALL MODELS OR ALL BUT ONE MODEL.
