Area forecast discussion, Aug 22, 8:15 PM EST, 1 hour 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 915 PM EDT FRI AUG 22 2003 THE FOLLOWING ARE THE FORECAST DISCUSSIONS FROM THE PAST 24 HOURS... WITH THE MOST RECENT FIRST. THIS PROVIDES A HISTORY OF THE DEVELOPMENT OF THE CURRENT FORECAST. ********************************************************************* EVENING FORECAST DISCUSSION 915 PM EDT FRI AUG 22 2003 STRONG TO SEVERE THUNDERSTORMS STILL OCCURRING ACROSS WEST CENTRAL PORTIONS OF THE FORECAST AREA. MSAS INDICATING DEWPOINTS STILL IN THE LOWER 70S AND LIS OF -5 TO -7 IN THIS AREA. HEAVY RAINFALL HAS OCCURRED OVER PARTS OF THE NORTHERN CUMBERLAND PLATEAU COUNTIES AND IS POSSIBLE ACROSS PARTS OF THE TENNESSEE VALLEY AND SOUTHERN CUMBERLAND PLATEAU OF SOUTHEAST TENNESSEE. NUMEROUS OUTFLOW BOUNDARIES WILL BE THE FOCUS FOR POSSIBLE LATER DEVELOPMENT TONIGHT AS THEY INTERACT WITH COLD FRONT NOW NEAR THE LOWER OHIO RIVER INTO CENTRAL OHIO AS IT MOVES SOUTHEAST. AIRMASS ACROSS NORTHEAST TENNESSEE AND SOUTHWEST VIRGINIA AREA HAS STABILIZED SOMEWHAT AFTER EARLIER ACTIVITY. WILL PROBABLY LOWER RAIN CHANCES THERE AND KEEP HIGHEST CHANCES IN THE SOUTH. UPDATE OUT AFTER 10 PM WHEN SOME OR ALL COUNTIES WILL BE DROPPED FROM WATCH. .MRX... NC...NONE. TN...NONE. VA...NONE. TD ********************************************************************* EARLY EVENING FORECAST DISCUSSION 655 PM EDT FRI AUG 22 2003 UPDATED ZONES FOR SEVERE THUNDERSTORM WATCH FOR NORTHERN CUMBERLAND PLATEAU AND TENNESSEE VALLEY COUNTIES. WATCH IN EFFECT UNTIL MIDNIGHT EDT. THUNDERSTORMS INCREASING ACROSS NORTHERN PART OF EAST TENNESSEE AHEAD OF COLD FRONT AND MCS MOVING ACROSS SOUTHERN KENTUCKY INTO NORTHERN TENNESSEE. TD ********************************************************************* AFTERNOON FORECAST DISCUSSION 300 PM EDT FRI AUG 22 2003 SHORT TERM...SHOWERS/THUNDERSTORMS HAVE DEVELOP OVER OUR VIRGINIA COUNTIES THIS AFTERNOON. MAIN CONCERN WITH THESE STORMS WILL BE RAIN AMOUNTS DUE TO SLOW MOVEMENT. EXPECT THE CONVECTION TO SPREAD OVER THE REMAINDER OF OUR AREA THROUGH THIS EVENING WITH MOST ACTIVITY CENTERED OVER EASTERN ZONES. THIS ALL IN RESPONSE TO THE MOIST...UNSTABLE AIR MASS THAT HAS SET UP IN ADVANCE OF THE COOL FRONT PROGGED TO TRACK ACROSS THE REGION LATE TONIGHT/EARLY SATURDAY. THE FRONT IS MOVING SLOWLY AND WE COULD SEE SOME LINGERING CONVECTION MAINLY OVER SOUTHERN AND EASTERN ZONES SATURDAY AFTERNOON. AS THE FRONT EXITS THE AREA A DRIER...STABLE AND SLIGHTLY COOLER AIR MASS WILL FILTER IN WITH AN UPPER LEVEL HIGH THE DOMINATE WEATHER FEATURE FOR THE REST OF THE SHORT TERM. CHA 71 90 67 90 / 30 30 20 0 TYS 70 88 67 87 / 40 40 10 0 TRI 67 84 65 84 / 70 40 10 0 OQT 70 88 67 87 / 40 30 10 0 MJB. ********************************************************************* MORNING FORECAST DISCUSSION (UPDATE) 922 AM EDT FRI AUG 22 2003 AREA RADARS FREE OF ANY SHOWERS/STORMS THIS MORNING...ALTHO CONVECTION IS NOTED OVER SRN OHIO VALLEY JUST SE OF THE COLD FRONT. MODIFIED BNA AND RNK 12Z SOUNDINGS SHOW ATMOSPHERE WILL BE HIGHLY UNSTABLE THIS AFTERNOON WITH CAPES OF 2500-3000 J/KG (LIFTED INDICES NEAR -7 DEGS C)...WITH A VERY HIGH FREEZING LEVEL AND WET BULB ZERO HEIGHT. SO...THREAT OF SEVERE IS VERY LOW AND MAIN CONCERN WILL BE LOCALLY HEAVY RAINS DUE TO WEAK WINDS ALOFT. STORM MOTION SHOULD BE A VERY SLOW DRIFT TO THE S OR SE. FOR UPDATE THIS MORNING...WILL REMOVE MENTION OF PATCHY MORNING FOG. ALSO...BASED ON YESTERDAYS COVERAGE AND LATEST SHORT RANGE MODELS THINK THAT POPS FOR NE PLATEAU AND SW VA SHOULD BE NUDGED UPWARD BY 10-15 PERCENT...CLOSER TO SE KY POPS IN THE CURRENT GRIDDED DATABASE. PROBABLY NO OTHER CHANGES NEEDED FOR NOW. TG ********************************************************************* EARLY MORNING FORECAST DISCUSSION 300 AM EDT FRI AUG 22 2003 TODAY AND TONIGHT...CURRENT SURFACE ANALYSIS SHOWS A COLD FRONT STRETCHING FROM NEAR DETROIT SOUTHWEST TO NEAR SAINT LOUIS. SATELLITE IMAGES REVEAL A BROKEN LINE OF TSTORMS OCCURRING ALONG THIS FRONT ACROSS OHIO AND INDIANA. MODELS ARE IN GENERAL AGREEMENT WITH MOVING THIS FRONT TOWARDS SOUTHWEST VA AND THE NORTHERN PLATEAU BY 00Z THIS EVENING...AND SLOWLY INTO THE FORECAST AREA THEREAFTER TONIGHT. A STRENGTHENING NORTHWEST UPPER-LEVEL FLOW WILL HELP TO CREATE A MODERATELY UNSTABLE AIRMASS AHEAD OF THE FRONT...WHICH SHOULD HELP GENERATE A BROKEN LINE OF TSTORMS ALONG THE FRONT AS IT MOVES INTO THE FORECAST AREA. WITH THE MODERATELY UNSTABLE AND VERY MOIST AIRMASS...THINK A FEW TSTORMS WILL BECOME SEVERE WITH DAMAGING WINDS AND LOCALLY HEAVY RAINFALL. IT APPEARS THAT UPPER-LEVEL DYNAMICS WILL NOT BE PARTICULARLY STRONG WITH THE FRONT...SO WILL NOT RAISE POPS INTO THE LIKELY CATEGORY ACROSS SOUTHWEST VA AND NORTHEAST TN FOR TONIGHT. LATER PERIODS...MAIN FORECAST CHALLENGE IS HOW MUCH PRECIP WILL LINGER INTO THE THIRD PERIOD. SURFACE COLD FRONT PASSES THROUGH THE FORECAST AREA SATURDAY MORNING WITH GFS BEING SLIGHTLY FASTER WITH THIS PROCESS THAN MESOETA. ANTICIPATE ANY LINGERING PRECIP TO EXIT THE SOUTHERN TIER BY OOZ SUNDAY. THIS IS SUPPORTED BY THE 21Z SHORT RANGE ENSEMBLES. BENIGN WEATHER ANTICIPATED THROUGH THE REMAINDER OF THE FORECAST CYCLE AS HEIGHTS RISE IN RESPONSE TO UPPER RIDGE BUILDING BACK INTO THE REGION AND HIGH PRESSURE DOMINATES AT THE SURFACE. PRELIMINARY NUMBERS FOLLOW: CHA 92 71 90 68 / 30 40 30 20 TYS 90 70 87 64 / 30 50 30 10 TRI 87 67 84 60 / 30 50 30 10 OQT 90 70 88 64 / 30 50 30 10 DMG/LCM *********************************************************************
