Area forecast discussion, Jun 9, 1:47 PM EDT, 1 hour 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 147 PM EDT TUE JUN 9 2009 .SYNOPSIS...COLD FRONT STATIONARY NEAR OR OVER THE AREA TONIGHT... THEN PUSHES NORTH ON WEDNESDAY. NEXT COLD FRONT MOVES THROUGH LATE THURSDAY/THURSDAY NIGHT. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP ACROSS THE REGION. THE GREATEST CONCENTRATION OF STORMS WAS ACROSS SOUTHEAST OHIO AND PORTIONS OF NORTHERN WEST VIRGINIA...WHERE A FEW OF THE STORMS HAVE ALREADY BECOME SEVERE. EXPECT THE CONVECTION SHOULD CONTINUE INTO THE LATE EVENING HOURS...BEFORE DISSIPATING. CONTINUED PREVIOUS THINKING OF PATCHY DENSE FOG ACROSS THE FAVORED VALLEY LOCATIONS. FOG AND ANY ASSOCIATED LOW CLOUDS SHOULD BURN OFF EARLY WEDNESDAY. WITH DAYTIME HEATING...EXPECT SHOWERS AND STORMS SHOULD ONCE AGAIN DEVELOP. GFS/NAM SUGGEST GREATEST CONCENTRATION OF STORMS WILL BE ACROSS SOUTHEAST OHIO DURING THE AFTERNOON. THESE MODELS ARE ALSO SUGGESTING A CONVECTIVE COMPLEX WILL MOVE ACROSS THE AREA WEDNESDAY NIGHT. SEE NO REAL REASON TO DOUBT IT AND HAVE GONE WITH LIKELY POPS. USED A BLEND OF MAX/MET NUMBERS AS WELL AS PREVIOUS FORECAST FOR TEMPS. && .SHORT TERM /THURSDAY THROUGH FRIDAY/... AFTER THE DIFFUSE FRONT LIFTS BACK NORTH THROUGH THE CWA...THE SHORT TERM FORECAST WILL BE DOMINATED BY NUMEROUS RIPPLES IN THE UPPER LEVEL FLOW THAT WILL SERVE TO SPARK CONVECTION ACROSS THE AREA AS THE WARM SECTOR REIGNS. CHALLENGE COMES FROM TRYING TO PUT HIGHER POPS IN AREAS WHERE MODELS AGREE ON STRONGER UPPER LEVEL FORCING ELEMENTS...BUT EVEN THIS FAR OUT...IT REMAINS A DAUNTING TASK. THE ATMOSPHERE WILL REMAIN UNSTABLE WITH SURFACE DEWPOINTS WELL INTO THE 60S. FORECAST SOUNDINGS SHOW A SATURATED COLUMN FOR WEDNESDAY AND THURSDAY...WITH PRECIPITABLE WATER VALUES RISING TO AROUND 2 INCHES. WITH THE PATTERN OF RECURRING CONVECTION...WATER ISSUES WILL BECOME A CONCERN FOR LOCATIONS THAT RECEIVE MULTIPLE BOUTS OF THUNDERSTORMS. ON THE OTHER HAND...WATER LOADING SHOULD DIMINISH THE SEVERE THREAT. AS THE SURFACE LOW PASSES TO THE NORTHEAST...THE STRONG COLD FRONT WILL PASS THROUGH THE CWA WITH A SIGNIFICANT CHANGE OF AIRMASS. THE MID LEVEL RIDGE THAT HAD BEEN STRONG ENOUGH TO KEEP THE PREVIOUS FRONT FROM MOVING THROUGH WITH WEAK NORTHWEST FLOW WILL GIVE WAY THIS TIME. A BRIEF CLEARING TREND WILL ALSO ENSUE BEHIND THE COLD FRONT. WHILE FIRMLY ENTRENCHED IN THE WARM SECTOR...THE WARM AND HUMID AIRMASS IN PLACE WEDNESDAY AND THURSDAY SHOULD BE HELD IN CHECK WITH POOR INSOLATION. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... MODELS CONTINUE TO SHOW TIMING ISSUES WITH THE MOVEMENT OF THE FRONT THROUGH THE EXTENDED PERIOD...HOWEVER...THE 12Z GFS LOOKS TO BE TRENDING TOWARD THE ECMWF SO PERHAPS THE MODELS ARE GETTING MORE IN SYNC. FOR NOW...IT APPEARS THAT THE INITIAL COLD FRONTAL PASSAGE WILL BE COMPLETE BY 12Z FRIDAY...WITH NORTHWEST FLOW IN PLACE AT THAT TIME. THE DEEPER MOISTURE WILL BE PULLING OUT...SO A SMALL CHANCE OF SHOWERS EARLY SHOULD GIVE WAY TO DRY WEATHER IN THE AFTERNOON AS HIGH PRESSURE BUILDS INTO THE REGION. THE SKY MAKE TAKE LONGER TO CLEAR HOWEVER AS THE NW FLOW AND LINGERING LOW LEVEL MOISTURE MAY HOLD ONTO THE CLOUDS LONGER. FOR FRIDAY NIGHT INTO SATURDAY...SFC HIGH PRESSURE SHOULD PROVIDE DRY WEATHER AS THE MOISTURE IS LIMITED AT BEST ACROSS THE AREA. THE QUESTION THEN BECOMES HOW QUICKLY WILL THE FRONT RETURN NORTHWARD. THE CANADIAN AND EARLIER GFS RUNS QUICKLY BROUGHT THE FRONT BACK NORTH AND SUGGESTED IT COULD RAIN AS EARLY AS SATURDAY NIGHT. FOR NOW HAVE JUST BEGUN TO EDGE THE CHANCES FOR RAIN BACK INTO THE REGION LATE SAT NIGHT AND THEN INCREASE THEM SOME SUNDAY THROUGH MONDAY AS ENERGY EJECTS OUT OF THE SWRN US TROUGH AND RIDES ACROSS THE RIDGE OVER THE SERN US. MOISTURE WILL DEFINITELY BE ON THE INCREASE AND WITH THE UNCERTAINTY ON THE TIMING OF THE WAVES...A CHANCE FOR A SHOWER IS POSSIBLE ANY TIME SUNDAY INTO MONDAY. FOR TEMPERATURES...GENERALLY FOLLOWED ALONG WITH THE HPC GUIDANCE AS THEY COMPARED WELL WITH THE 850 MB TEMP FCST AND ALSO WITH THE CLOUDS AROUND...WHICH SHOULD HOLD THE HIGHS DOWN JUST A TOUCH DAY 6 AND 7 ALONG WITH ALLOWING FOR A SLOW MODERATION OVERNIGHT FOR LOWS. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... SATELLITE AND RADAR IMAGES SHOW SHOWERS AND ISOLATED THUNDERSTORMS ARE BEGINNING TO DEVELOP ACROSS PORTIONS OF SOUTHEAST OHIO AND NORTHERN WEST VIRGINIA. THESE STORMS ARE DEVELOPING IN RESPONSE TO A COLD FRONT WHICH WAS PUSHING SOUTHEAST TOWARD THE REGION. SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE JUST ABOUT EVERYWHERE THIS AFTERNOON. OUTSIDE OF THE STORMS...VFR CONDITIONS ARE ANTICIPATED. SOME OF THE STRONGER STORMS WILL BE CAPABLE OF PRODUCING SMALL HAIL AND GUSTY WINDS. THE STORMS SHOULD DIMINSH AFTER SUNSET...WITH MOST OF THE REGION DRY BEFORE MIDNIGHT. DEPENDING ON WHAT AREAS RECEIVE RAIN TODAY...PATCHY DENSE FOG IS POSSIBLE AFTER MIDNIGHT WITH FAVORED VALLEY LOCATIONS SEEING IFR/LIFE CONDITIONS. THE FOG SHOULD BURN OFF EARLY WEDNESDAY WITH VFR CONDITIONS EXPECTED EVERYWHERE BY 15Z. DUE TO EQUIPMENT PROBLEMS AT PKB...MENTIONED AMD NOT SKED IN TAFPKB. AVIATION OUTLOOK /BEYOND 06Z WEDNESDAY/... AREAS OF IFR CONDITIONS POSSIBLE WEDNESDAY NIGHT INTO THURSDAY. && .EQUIPMENT... PKB IS OTS ON ACCOUNT OF A POWER OUTAGE DUE TO A THUNDERSTORM. && .RLX WATCHES/WARNINGS/ADVISORIES... WV...NONE.
