AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MORRISTOWN TN 239 PM EDT WED JUN 16 2010 .SHORT TERM (TONIGHT AND THURSDAY)... CONVECTION IS BEGINNING TO DEVELOP ALONG THE CUMBERLAND PLATEAU...AND WILL BE TRACKING INTO THE VALLEY THROUGH THE AFTERNOON. CONVERGE SHOULD INCREASE QUICKLY AS OUTFLOW BOUNDARIES HELP BREAK THE CAP AND INITIATE NEW CONVECTION. FORECAST CAPE VALUES ACROSS THE AREA WILL BE AROUND 2500 J/KG...ENOUGH FOR SOME PULSE STORMS TO PRODUCE STRONG WIND GUSTS AND SOME HAIL. SEVERE THREAT SHOULD BE MORE ISOLATED THAN YESTERDAY THOUGH. THE LACK OF LARGE SCALE LIFT SHOULD RESULT IN ANY STORMS DISSIPATING WITH SUNSET...SO WILL REMOVE ALL POPS FROM THE FORECAST AFTER MIDNIGHT. A FRONT ACROSS THE OHIO VALLEY TODAY WILL PUSH SOUTHWARD OVERNIGHT. THIS WILL BRING A DRIER AND MORE STABLE AIR MASS TO THE AREA. DEWPOINTS TOMORROW AFTERNOON ARE FORECAST TO BE 10 DEGREES LOWER THAN TODAY. IN THE MID AND UPPER LEVELS...A RIDGE WILL BE BUILDING OVER THE REGION...AND THE FLOW ALOFT WILL BE NORTHWESTERLY.
