AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 402 PM EDT SUN JUN 17 2007 .SYNOPSIS... A WEAK FRONT WILL MOVE INTO CENTRAL OHIO THIS EVENING RESULTING IN SCATTERED SHOWERS AND THUNDERSTORMS. MIDLEVEL RIDGE WILL THEN STRENGTHEN OVER THE OHIO VALLEY ON MONDAY...BEFORE A COLD FRONT MOVES THROUGH ON TUESDAY. && .NEAR TERM /UNTIL 10 PM THIS EVENING/... VERY WEAK FRONTAL BOUNDARY ACROSS THE NORTHERN CWA COMBINING WITH WEAK MIDLEVEL IMPULSE TO CREATE SCATTERED SHOWERS AND THUNDERSTORMS...MAINLY ACROSS THE NORTHERN HALF OF THE CWA. SHEAR IS VERY WEAK SO STORMS WILL BE PULSE IN NATURE. A FEW DOWNBURSTS MAY BRING ISOLATED GUSTY WINDS BUT WEAK INSTABILITY AND MARGINAL DELTA THETA-E VALUES DO NOT SUPPORT SEVERE WINDS. ACTIVITY SHOULD QUICKLY TAPER OFF FROM WEST TO EAST THROUGH 03Z AS INSTABILITY IS LOST...AND MIDLEVEL WAVE EXITS TO THE EAST. && .SHORT TERM /10 PM THIS EVENING THROUGH TUESDAY NIGHT/... WENT CLOSE TO WARMER MET NUMBERS ACROSS THE WEST OVERNIGHT...AND A BIT COOLER EAST WHERE WINDS WILL BE LIGHTER. MOS NUMBERS HAVE COME IN A BIT COOLER FOR HIGHS MONDAY. HOWEVER WITH H8 TEMPS WARMING TO NEAR 20 DEG C...MIDLEVEL RIDGING BECOMING STRONGER AND THE FACT THAT TEMPS CURRENTLY ARE ALREADY IN THE LOW TO MID 90S THIS AFTERNOON...HAVE GONE SEVERAL DEGREES ABOVE MOS FOR HIGHS ON MONDAY. THIS GIVES HIGHS IN THE MID 90S AREAWIDE. MAIN FOCUS FOR THE SHORT TERM PERIOD IS COLD FRONT COMING IN ON TUESDAY AS UPPER LEVEL TROUGH MOVES ACROSS THE GREAT LAKES. NAM AND GFS BOTH FORECAST PRECIP WELL AHEAD OF THE FRONT OVERNIGHT MONDAY AND EARLY TUES...WITH WEAK IMPULSES EMBEDDED IN SWRLY FLOW ALOFT MOVING INTO SOME ELEVATED INSTABILITY. SPED UP ONSET OF POPS SLIGHTLY TUESDAY MORNING...BUT ONLY MADE MINOR TWEAKS TO POPS FOR THE REMAINDER OF THE DAY. KEPT LIKELY POPS SINCE GOOD FRONTAL CONVERGENCE SHOULD BE SUFFICIENT FOR WIDESPREAD PRECIP...BUT STILL UNCERTAIN HOW MORNING PRECIP WILL IMPACT INSTABILITY LATER IN THE DAY. QUICK END TO PRECIP FROM WEST TO EAST TUESDAY NIGHT WITH FRONT MOVING THROUGH. HAWBLITZEL && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... HIGH PRESSURE WILL BUILD ACROSS THE REGION FROM WEDNESDAY THROUGH FRIDAY BRINGING A RETURN TO DRY WEATHER. INITIALLY TEMPERATURES WILL BE BACK CLOSER TO SEASONAL NORMS BUT THEN GRADUALLY WARM UP TOWARDS THE END OF THE WEEK. THERE IS SOME UNCERTAINTY OVER THE WEEKEND CONCERNING THE POTENTIAL FOR A FRONT TO SAG TOWARDS THE OHIO VALLEY WHICH COULD PRODUCE SOME THUNDERSTORMS. HAVE OPTED TO LIMIT LOW CHANCE POPS TO SUNDAY WHICH APPEARS TO HAVE A SOMEWHAT BETTER CHANCE AT THIS POINT IN TIME. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... A WEAK S/W AND BNDRY WERE SAGGING SLOWLY SE ACROSS THE REGION THIS AFTERNOON. LOOKING AT RADAR TRENDS...KDAY AND THEN KILN ARE THE MOST LIKELY TERMINALS TO HAVE STORMS THROUGH 23Z. MVFR VISIBILITIES ARE POSSIBLE WITH THE STORMS. SCT MID LEVEL CLOUDS EXPECTED AFTER 02Z MON WITH BKN HIGH/MID CLOUDS AFT 08Z.
