NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 24, 3:06 PM EST, 2 hours 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 406 PM EDT TUE JUN 24 2014 .SYNOPSIS... SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE REGION TODAY AND TONIGHT...IN A MOIST AIR MASS AHEAD OF AN UPPER LEVEL DISTURBANCE. AFTER A FRONT CROSSES THE REGION WEDNESDAY MORNING...CONDITIONS WILL BE SLIGHTLY DRIER FOR WEDNESDAY AND THURSDAY. A MOIST AND UNSTABLE AIR MASS WILL RETURN FOR FRIDAY AND THE WEEKEND...BRINGING MORE CHANCES FOR SHOWERS AND STORMS. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... A VERY MOIST AIR MASS IS IN PLACE OVER THE REGION TODAY. PRECIPITABLE WATER VALUES ARE LIKELY ALREADY AROUND AN INCH AND THREE QUARTERS...AND WILL INCREASE TO NEAR TWO INCHES LATER TONIGHT. INSTABILITY HAS GROWN TO AROUND 2000 J/KG MLCAPE...DESPITE WEAK MID-LEVEL LAPSE RATES AND A MOIST-ADIABATIC SOUNDING. THIS IS THANKS TO TEMPERATURES AT THE SURFACE THAT HAVE RISEN INTO THE LOWER TO MID 80S FOR MOST OF THE ILN CWA. THE REGION IS CURRENTLY ON THE FAVORABLE SIDE OF AN APPROACHING SHORTWAVE...WITH AN AXIS THAT IS FORECAST TO BE MOVING INTO INDIANA TONIGHT. THERE IS ALSO EVIDENCE OF A SMALL MESOSCALE VORT MAX MOVING INTO INDIANA RIGHT NOW. AT THE SURFACE...FLOW REMAINS GENERALLY SOUTHERLY...WELL AHEAD OF A COLD FRONT AND WEAK DEVELOPING SURFACE LOW. THE MOISTURE AND INSTABILITY WILL CONTINUE TO LEAD TO A CONVECTIVELY VOLATILE ENVIRONMENT. WITH WIND SHEAR NOT ESPECIALLY STRONG (30 KNOTS AT BEST)...AND FORCING ONLY MARGINALLY FOCUSED...A WIDESPREAD SEVERE THREAT IS NOT EXPECTED TO DEVELOP. HOWEVER...THERE WILL BE A THREAT FOR WET DOWNBURSTS WHICH MAY CAUSE ISOLATED STRONG TO SEVERE WINDS. ANOTHER THREAT (AND JUST AS SIGNIFICANT) WILL BE THE POSSIBILITY OF HEAVY RAIN. EVERY STORM WILL BE CAPABLE OF PRODUCING DOWNPOURS TODAY...AND ANYTHING PROLONGED OR WITH A FAVORABLE SSW-TO-NNE ORIENTATION MAY PRODUCE LOCALIZED FLOODING. THOUGH THIS FORECAST PACKAGE STOPS JUST SHORT OF FLASH FLOOD WATCH ISSUANCE...THE OVERALL SETUP SUGGESTS THAT A THREAT FOR ISOLATED FLASH FLOODING WILL EXIST...BUT WITHOUT A WHOLE LOT OF CONFIDENCE IN ANY PARTICULAR SEGMENT OF THE ILN CWA. WHILE THE SITUATION NEAR INDIANAPOLIS WOULD INDICATE THAT A TORNADO THREAT CANNOT BE COMPLETELY DISCOUNTED...LOW-LEVEL WIND SHEAR IS MORE FAVORABLE FURTHER TO THE WEST...CLOSER TO THE AREA OF VORTICITY. CONVECTIVE COVERAGE IS EXPECTED TO MAXIMIZE OVER THE WESTERN HALF OF THE FORECAST AREA BETWEEN 21Z AND 03Z...WHERE CATEGORICAL POPS ARE IN THE FORECAST. THERE MAY BE SOME LEVEL OF DIURNAL DISSIPATION AS THINGS MOVE EAST...SO LIKELY POPS WILL BE MAINTAINED FOR THE EASTERN HALF OF THE CWA. WITH THE COLD FRONT STILL FORECAST TO BE OUTSIDE OF THE REGION BY MORNING...MIN TEMPS ARE QUITE WARM...HOLDING IN THE UPPER 60S TO NEAR 70 DEGREES. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... THE SHORTWAVE WILL BE EXITING THE REGION TO THE EAST ON WEDNESDAY...DRAWING THE ENHANCED AREA OF DEEP MOISTURE AWAY FROM THE ILN CWA. A COLD FRONT WILL ALSO BE MOVING THROUGH...SHIFTING SURFACE WINDS TO THE NORTHWEST. THOUGH SOME PRECIPITATION AHEAD OF THESE FEATURES MAY CONTINUE IN THE MORNING ACROSS THE FAR EASTERN ILN CWA (CENTRAL OHIO THROUGH THE SCIOTO VALLEY)...MUCH DRIER CONDITIONS ARE EXPECTED OVERALL. WEAK INSTABILITY WILL STILL BE ABLE TO DEVELOP IN THE AFTERNOON...LEADING TO A CHANCE FOR SOME CONVECTIVE SHOWERS AND THUNDERSTORMS BY AFTERNOON...BUT NOTHING WORTH MORE THAN A 20-30 PERCENT CHANCE OF PRECIPITATION. THESE CHANCES ARE EXPECTED TO BE DIURNALLY DRIVEN...AND WILL DIMINISH AFTER DARK. BEHIND THE FRONT...TEMPERATURES WILL BE A LITTLE COOLER FOR BOTH WEDNESDAY AND WEDNESDAY NIGHT. && .LONG TERM /THURSDAY THROUGH TUESDAY/... HIGH PRESSURE WILL ALLOW FOR DRY CONDITIONS ACROSS THE FA ON THURSDAY. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE ON FRIDAY ACROSS PRIMARILY WESTERN PORTIONS OF THE FA. THE BETTER CHANCE FOR STORMS ACROSS THIS AREA WILL BE DURING THE AFTERNOON DUE TO DAYTIME HEATING. A DISTURBANCE WORKS INTO THE REGION ON SATURDAY PROVIDING A BETTER CHANCE FOR SHOWER AND THUNDERSTORM ACTIVITY ACROSS THE REGION. THIS ACTIVITY WILL DECREASE DURING THE EVENING HOURS SATURDAY EVENING. ADDITIONAL THUNDERSTORMS WILL BE POSSIBLE ON SUNDAY PRIMARILY DURING PEAK HEATING. ANOTHER DISTURBANCE WILL MOVE THROUGH PRIMARILY NORTHERN PORTIONS OF THE FA ON MONDAY. SHOWER AND THUNDERSTORM CHANCES INCREASE ON TUESDAY AS A COLD FRONT APPROACHES THE REGION. HIGH TEMPERATURES WILL GENERALLY BE IN THE 80S THROUGH TUESDAY. SOME LOCATIONS ALONG AND SOUTH OF THE OHIO RIVER HAVE HIGH TEMPERATURES IN THE LOWER 90S EXPECTED MONDAY AND TUESDAY. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... MID LEVEL DISTURBANCE TO OUR WEST THIS AFTERNOON WILL SLOWLY PUSH EAST THROUGH OUR REGION TONIGHT INTO WEDNESDAY MORNING. THIS FEATURE WILL INTERACT WITH A VERY MOIST AIRMASS TO PRODUCE WIDESPREAD SHOWERS AND THUNDERSTORMS. A WEAK TO LOW END MODERATE UNSTABLE AIRMASS THIS AFTERNOON AND THIS EVENING WILL BRING THE GREATEST THREAT FOR THUNDERSTORMS...BUT AS THE ATMOSPHERE COOLS...THUNDERSTORMS WILL DWINDLE IN COVERAGE OVERNIGHT AS SHOWERS BECOME MORE PREVALENT. HEAVY RAIN WILL BE POSSIBLE IN THUNDERSTORMS WHICH WILL REDUCE CEILINGS INTO THE MVFR CATEGORY WITH VISIBILITIES DROPPING INTO THE IFR CATEGORY. AS THE AIRMASS MOISTENS OVERNIGHT...AND AS A SFC TROF SLOWLY PUSHES EAST...CEILINGS WILL EVENTUALLY BECOME PREDOMINANT IFR LATE TONIGHT INTO WEDNESDAY MORNING. ON WEDNESDAY...DISTURBANCE MOVES EAST AND REGION WILL BE IN A RELATIVE LULL IN TERMS OF PRECIPITATION CHANCES. LOW CEILINGS WILL EVENTUALLY LIFT TO VFR BY THE AFTERNOON HOURS. A WEAK COLD FRONT IS FORECAST TO DROP SOUTH ACROSS THE REGION WEDNESDAY NIGHT. A SMALL CHANCE OF A SHOWER OR STORM MAY OCCUR WITH THIS FRONT WITH WEAK HIGH PRESSURE BUILDING INTO THE AREA BY THURSDAY MORNING. OUTLOOK...THUNDERSTORMS POSSIBLE FRIDAY THROUGH SUNDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
