NWS Columbia, SC wrote its last area forecast discussion before the first event at Oct 14, 7:10 AM EST, 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE COLUMBIA SC 810 AM EDT TUE OCT 14 2014 .SYNOPSIS... HIGH PRESSURE CENTERED OFF THE MIDDLE ATLANTIC COAST WILL DIRECT A MOIST ONSHORE FLOW INTO THE FORECAST AREA AHEAD OF AN APPROACHING COLD FRONT. THE FRONT WILL MOVE INTO THE AREA TONIGHT. NUMEROUS SHOWERS AND THUNDERSTORMS WILL OCCUR AHEAD OF THE FRONT. THE FRONT MAY LINGER IN THE FORECAST AREA WEDNESDAY BUT DEEPER MOISTURE AHEAD OF THE FRONT WILL SHIFT EASTWARD EARLY AND THE SHOWER CHANCE WILL DIMINISH. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... TORNADO WATCH HAS BEEN ISSUED FOR THE ENTIRE FORECAST AREA THROUGH 2PM. THIS MORNING...DYNAMIC STORM SYSTEM TO THE WEST CONTINUES TO PRODUCE STRONG STORMS AND VERY HEAVY RAINFALL ACROSS EASTERN AL/TN/CENTRAL GA EARLY THIS MORNING. THIS SYSTEM IS MOVING FASTER THAN MODELS HAVE SHOWN. THE THREAT OF STRONG TO SEVERE STORMS WILL INCREASE BY MIDDAY AS A LINE OF CONVECTION RE-INTENSIFIES AHEAD OF THE APPROACHING COLD FRONT. HAVE SPED UP POP TIMING BASED ON LATEST RADAR TRENDS. HRRR AND RAP SIMULATED REFLECTIVITY HAVE BEEN A COUPLE OF HOURS BEHIND WITH TIMING ON THE LAST SEVERAL RUNS. TIMING IS DIURNALLY FAVORABLE WITH THE MAIN AREA OF CONVECTION EXPECTED TO REACH THE CSRA WITHIN THE 18Z TO 20Z TIME FRAME. CONVECTIVE ANALYSIS REVEALS MODERATE INSTABILITY BY THIS AFTERNOON WITH CAPE AROUND 1000 TO 1500 J/KG. MODEL SOUNDINGS SHOW STRONG UNIDIRECTIONAL SHEAR PROFILES WITH 0 TO 6 KM SHEAR AROUND 30 TO 35 KNOTS. THE MAIN THREAT WILL LIKELY BE STRONG WINDS. TORNADO THREAT IN DISCRETE CELLS AHEAD OF THE MAIN LINE IS ALSO POSSIBLE IN ADDITION TO SMALL HAIL. THE NAM AND GFS SHOW PRECIPITABLE WATER INCREASING TO NEAR 2 INCHES TOWARD THE END OF THE DAY WHICH INDICATES POTENTIAL FOR HEAVY RAINFALL. THE PRESSURE GRADIENT WILL TIGHTEN PROMOTING SOUTHEASTERLY WINDS AROUND 10 TO 15 KNOTS TODAY WITH GUSTS NEAR 20 TO 25 KNOTS. EXPECT A GRADIENT IN TEMPERATURES FROM WEST TO EAST TODAY WITH HIGHS IN THE UPPER 70S WEST TO MIDDLE 80S EAST. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... MODELS HAVE BEEN A LITTLE SLOW WITH THE MOVEMENT OF THE CURRENT ACTIVITY...BUT FOR THE MOST PART THE MAIN AREA OF SHOWERS AND THUNDERSTORMS SHOULD BE MOVING THROUGH THE FORECAST AREA EARLY THIS EVENING...PROBABLY ALONG A PREFRONTAL TROUGH. INSTABILITY SHOULD REMAIN MARGINAL THROUGH THE EVENING...BUT THE SHEAR ACROSS THE REGION WILL BE STRONG. STRONG LOW-LEVEL JET OF 35 TO 40 KNOTS WILL BE MOVING OVER THE FORECAST AREA...AND THIS WILL BE COUPLED WITH AN EVEN STRONGER MID AND UPPER LEVEL JET. MUCH OF THE ENERGY WILL BE PARALLEL TO THE MAIN UPPER FLOW...AND WHEN YOU ADD IN PW VALUES AROUND 2 INCHES THIS EVENING...WE CAN EXPECT PERIODS OF HEAVY RAINFALL. BULK OF THE ACTIVITY THIS EVENING WILL BE MOVING THROUGH BETWEEN 00Z-05Z...THEN EXPECT LIGHTER SHOWERS AND STORMS AS THE STRONGEST ACTIVITY MOVES EAST OF THE CWA. SHOWERS SHOULD LINGER OVERNIGHT...BUT CHANCES FOR RAINFALL WILL BEGIN TO DIMINISH TOWARDS WEDNESDAY MORNING AS THE MAIN FRONT MOVES INTO AND THROUGH THE REGION. TEMPERATURES NOT EXPECTED TO FALL MUCH THROUGH THE EVENING AND EVEN THROUGH MIDNIGHT. EXPECT BEST TEMPERATURE DROP TO BE AFTER MIDNIGHT ONCE THE MAIN FRONTAL BOUNDARY BEGINS PUSHING THROUGH THE AREA. FOR WEDNESDAY AND WEDNESDAY NIGHT...THE MAIN FRONT WILL BE PUSHING EAST OF THE CWA EARLY IN THE DAY...ALONG WITH THE DEEPER MOISTURE. HOWEVER DUE TO THE MAIN UPPER LOW STILL WEST OF THE CWA...WOULD NOT BE SURPRISED TO SEE SOME SHOWER ACTIVITY ACROSS THE UPSTATE AND POSSIBLY EXTREME WESTERN CWA. EVEN SO...HAVE DRIED THE FORECAST OUT ACROSS THE AREA BY WEDNESDAY AFTERNOON. HIGHS DURING THE DAY WILL BE COOLER BEHIND THE FRONT...WITH READINGS IN THE MIDDLE 70S. WEDNESDAY NIGHT WILL SEE A DRIER AND COOLER AIRMASS ACROSS THE REGION. WINDS ARE FORECAST TO REMAIN UP OVERNIGHT. OVERNIGHT LOWS ON WEDNESDAY NIGHT WILL BE IN THE LOWER TO MIDDLE 50S...WITH ISOLATED SPOTS POSSIBLY REACHING THE UPPER 40S. && .LONG TERM /THURSDAY THROUGH MONDAY/... LONGER TERM MODELS STILL INDICATING A DRY FORECAST PATTERN THROUGH THE MAJORITY OF THE LONGER TERM PERIOD. LOW PRESSURE IN THE GREAT LAKES REGION WITH RIDGING ALONG THE GULF COAST SHOULD DIRECT A DRY WESTERLY FLOW INTO THE FORECAST AREA EARLY. THE MODELS SHOW A WEAK FRONT WILL LITTLE CONVERGENCE AND MOISTURE SATURDAY WITH RIDGING DOMINATING SUNDAY AND MONDAY. THE GUIDANCE SUPPORTS NEAR OR SLIGHTLY ABOVE NORMAL TEMPERATURES. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... RESTRICTIONS LIKELY WITH SHOWERS AND THUNDERSTORMS THIS MORNING INTO THIS AFTERNOON AND EVENING. A LINE OF HEAVIER SHOWERS AND THUNDERSTORMS WILL MOVE INTO THE CENTRAL SAVANNAH RIVER AREA AFTER 12Z. MVFR AND BRIEF IFR VISIBILITIES POSSIBLE AS THE LINE SHIFTS EASTWARD INTO THE CENTRAL MIDLANDS BY LATE MORNING. STRONG WIND GUSTS OF 25 KNOTS OR HIGHER ARE LIKELY WITH THE HEAVIER STORMS AND ALSO AHEAD OF A COLD FRONT CURRENTLY PUSHING EAST ACROSS ALABAMA. FRONTAL PASSAGE ACROSS SC WILL OCCUR LATER THIS EVENING AND OVERNIGHT WITH PRECIPITATION TAPERING OFF. EXTENDED AVIATION OUTLOOK...RESTRICTIONS POSSIBLE IN SHOWERS AND THUNDERSTORMS WEDNESDAY MORNING AS THE COLD FRONT SHIFTS EAST. OTHERWISE...NO SIGNIFICANT IMPACTS TO AVIATION EXPECTED WITH A DRIER AIRMASS MOVING INTO THE AREA. && .CAE WATCHES/WARNINGS/ADVISORIES... SC...NONE. GA...NONE. && 99
