AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MORRISTOWN TN 858 AM EDT SAT JUN 19 2010 .DISCUSSION... CONVECTOIN HAS DEVELOPED OVER MIDDLE TN EARLIER THAN EXPECTED DUE TO AN APPROACHING SHORTWAVE TROUGH. THE MODELS ARE DOING A VERY POOR JOB OF PICKING UP ON THIS CONVECTION. AN EARLY UPDATE WILL NEED TO BE ISSUED TO RAISE POPS IN ALL LOCATIONS...BUT ESPECIALLY IN THE PLATEAU. WILL BRING POPS UP TO LIKELY THERE. TEMPS WILL ALSO BE ADJUSTED DOWNWARD ACCORDINGLY. CONVECTIVE PARAMETERS FROM THE 12Z OHX SUGGEST A POTENTIAL FOR SEVERE WEATHER TODAY. THE OHX SOUNDING MODIFIED TO 92/70 YIELDS AN LI OF -6 AND CAPE VALUES AROUND 3000 J/KG. MODEL FORECAST SOUNDINGS IN OUR AREA THIS AFTERNOON INDICATE SIMILAR NUMBERS. A WBZ HEIGHT OF NEARLY 14KFT SHOULD MEAN A MINIMAL HAIL THREAT...BUT A SURFACE TO MIDLEVEL THETA-E DIFFERENCE OF 35 C SUGGESTS DAMAGING DOWNBURTS WILL BE THE MAIN CONCERN. && .MRX WATCHES/WARNINGS/ADVISORIES...
