AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 734 PM EDT FRI JUN 18 2010 .SYNOPSIS... HIGH PRESSURE EAST OF THE REGION WILL CONTINUE TO PULL AWAY FROM THE REGION TONIGHT. A COLD FRONT WILL DROP ACROSS THE GREAT LAKES AND OHIO VALLEY SATURDAY INTO SATURDAY NIGHT...BRINGING A CHANCE OF THUNDERSTORMS. HIGH PRESSURE WILL SETTLE BACK OVER THE GREAT LAKES ON SUNDAY. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... UPDATED THE NORTH TO INCLUDE A WATCH. UPPED POPS TO LIKELY ACROSS THE EXTREME NORTH WITH A TIGHT GRADIENT DOWN TO I-70 THIS EVENING. REST OF FCST LEFT AS IS. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... SHORT RANGE MODELS ARE IN REASONABLE AGREEMENT IN BRINGING CDFNT ACROSS THE AREA SAT AFTN/EVNG. MODELS DIFFER ON AMOUNT OF CONVECTION THAT DEVELOPS ALONG THE FRONT. GFS/CANADIAN GLOBAL SEEM TO DEVELOP THE MOST. MODELS DO AGREE THAT THE ATMOSPHERE DESTABILIZE ON SATURDAY AHEAD OF FNT WITH CAPES OF SEVERAL THOUSAND J/KG. CONTINUED WITH PREVIOUS FCST OF SCATTERED TSTMS WITH THE GREATER COVERAGE IN THE NORTHERN ZONES. WENT A LITTLE ABOVE THE MOS DEWPOINTS...INTO THE LOWER 70S...FOR DEWPOINTS TOMORROW. WRN OH VLY HAS THESE VALUES TODAY. THIS PUSHES HI TO NEAR 100 FOR SATURDAY. WILL COVER THIS WITH AN SPS. TSTMS SHOULD LINGER INTO SAT NGT WAS FNT CONTINUES TO PUSH S THRU THE REGION. BY 12Z SUN FNT SHOULD BE S OF THE REGION...AS HIGH PUSH SETTLES OVER THE GREAT LAKES. SUN SHOULD BE MOSTLY SUNNY. FOR SUN NGT...MODELS ARE TRYING TO HINT AT DEVELOPMENT OF MCS OUT OVER THE MIDWEST...AN MAYBE BRING IT INTO WRN PART BY THE END OF SUN NGT. ATTM DECIDED TO LEAVE SUN NGT DRY. GFS MOS CONTINUES TO LOOK TOO WARM FOR HIGHS...SO RAN A GFS/NAM MOS SPLIT FOR HIGHS OVER THE WEEKEND. && .LONG TERM /MONDAY THROUGH FRIDAY/... H5 RIDGE PEAKS OVER THE UPPER MIDWEST AT DAYBREAK ON SUNDAY WITH EMBEDDED S/W AND VORT MAXES ROLLING OFF OF IT AND MOVING SOUTHEAST INTO THE OHIO VALLEY. AFTER THIS THE UPPER RIDGE GETS BEATEN DOWN WITH A MYRIAD OF UPSTREAM S/WS TO EVENTUALLY EVOLVE INTO A ZONAL WESTERLY FLOW BY MONDAY NIGHT. THIS ZONAL FLOW IS ALSO SUPPORTIVE OF THE HODGE PODGE OF DISTURBANCES SWINGING THROUGH THE NORTHERN OHIO VALLEY FOR MUCH OF THE FORECAST PERIOD. UPPER LEVEL DRYING IS NOTED BRIEFLY ON WEDNESDAY UNTIL THE PATTERN REPEATS ITSELF WITH RIDGING OVER THE GREAT PLAINS STRENGTHENING AND A CONTINUED SE FLOW THAT WOULD BE RECEPTIVE FOR MCS PROPAGATION THROUGH THE OHIO VALLEY. EUROPEAN H5 PATTERN IS SIMILAR BUT BEGINS SLIGHTLY LESS AMPLIFIED ON SUNDAY AND HAS A HIGHER FREQUENCY OF BUILDING A WEAK BUT NOTICEABLE RIDGE IN THE PLAINS AT 0Z MON AND 12Z WED BEFORE IT BREAKS DOWN AND SUBSEQUENT MCSS SLIDE THROUGH THE OHVLY. MODEL DIFFERENCES ASIDE...THE PATTERN OF NOCTURNAL CONVECTION HITTING THE OHIO VALLEY WILL CONTINUE. A COLD FRONT WILL INCREASE THE CHANCE OF RAIN ON TUESDAY NIGHT AND WEDNESDAY. SURFACE PATTERN DIVERGES BASED ON MODEL CHOICE AFTER THIS TIME...AND HPC WAS INDICATING A BOUNDARY PUSHING THROUGH THE REGION EVEN AS A RIDGE OF HIGH PRESSURE SETTLES OVER THE EASTERN U.S...WHICH APPEARS TO BE COUNTERINTUITIVE. TRIED TO DRY OUT THE FORECAST AT THE END OF THE PERIOD IN WHAT SHOULD BE A POST FRONTAL ENVIRONMENT. && .AVIATION /23Z FRIDAY THROUGH WEDNESDAY/... FOCUS WITH THE EARLY PART OF THE FORECAST IS UPSTREAM CONVECTION. THERE REMAINS A BIT OF UNCERTAINTY WITH THE TRACK OF THE MCS PROGRESSING ACROSS NORTHERN INDIANA. THE CURRENT FORECAST WILL ASSUME THIS WILL MOSTLY TRACK NORTH AND/OR WEAKEN BEFORE REACHING THE TAF SITES. CANNOT RULE THINGS OUT SO TRIED TO TIME OUT THE MOST LIKELY TIME AND INCLUDE A CB MENTION AT 02Z-04Z FOR DAYTON AND 03Z-05Z AT WILMINGTON AND COLUMBUS. TRENDS WILL BE CLOSELY MONITORED OVER THE NEXT COUPLE OF HOURS AND AMENDMENTS MAY BECOME NECESSARY. WILL GO FOR SOME MVFR FOG AT KILN/KCVG OVERNIGHT AND IFR AT KLUK. A COLD FRONT WILL THEN MOVE INTO AN UNSTABLE AIRMASS OVER THE REGION ON SATURDAY. EXPECTING A CHANCE OF SHOWERS AND THUNDERSTORMS TO DEVELOP. RIGHT NOW ACTIVITY LOOKS TO BE SCATTERED IN NATURE...AND IT WOULD BE HARD TO PIN DOWN EXACT PLACEMENT OF STORMS. SO WILL INCLUDE A CB MENTION FOR NOW. .OUTLOOK...THUNDERSTORMS POSSIBLE SATURDAY EVENING...THEN AGAIN MONDAY THROUGH TUESDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
