Area forecast discussion, Jun 26, 2:44 PM CDT, 2 hours 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
244 PM CDT TUE JUN 26 2001

CURRENTLY...SCATTERED THUNDERSTORM ACTIVITY CONTINUED ACROSS MIDDLE
TENNESSEE. COLD POOL ALOFT AND HEATING OF THE DAY HAS RESULTED IN
LI'S OF -4 TO (-7)...AND CAPE VALUES BETWEEN 1300-1700 J/KG. HAVE
HAD HAIL AND WIND EVENTS SNEAKING INTO THE SEVERE CATEGORY. THE
STORMS WERE LINING UP WITH A MESOSCALE WIND CONVERGENCE BOUNDARY
FROM NRN MISSISSIPPI THROUGH SOUTHERN MIDDLE TENNESSEE. THE H5 LOW
IS SITTING OVER THE TENNESSEE RIVER IN OUR WESTERN CWA.

FORECAST CONCERNS...THUNDERSTORM CHANCES THROUGH THE WEEKEND.
DEALING WITH TEMPS UNDER THE UPPER LEVEL COOL POOL.

CURRENT ACTIVITY WILL BECOME ISOLATED THIS EVENING SHORTLY AFTER
DIURNAL HEATING ENDS. BROKEN SKY WILL LIKELY BECOME PARTLY CLOUDY
THROUGH THE NIGHT. DEW POINTS IN THE LOW 60S WILL RESULT IN 60 TO 65
TEMPERATURES BY MORNING...COOLER IN THE PLATEAU. WILL BREAK UP WEST
INTO 2 ZONES FOR TONIGHT...SINCE MOST OF THE ACTIVITY IS LOCATED
IN SOUTHERN MIDDLE TENNESSEE. WILL HAVE A HIGHER POP THERE.

MODELS ARE IN DECENT AGREEMENT WITH TAKING THE UPPER LEVEL LOW WEST-
NORTHWEST OF THE MIDSTATE OVER THE NEXT COUPLE OF DAYS. ACTIVITY HAS
BEEN PREVALENT ALONG THE EAST SIDE OF THE LOW. MODEL RESOLUTION IS
NOT GOOD ENOUGH TO PINPOINT THE BEST DEFORMATION OR LOW LEVEL
BOUNDARIES WITH THIS SYSTEM...HOWEVER...BEST LAPSE RATES TOMORROW DUE
TO COLD AIR ALOFT WILL ALIGN IN THE WESTERN HALF OF THE CWA...ALONG
WITH THE BEST LOW LEVEL JUICY AIR. THE CONVERGENCE WILL BE THE
QUESTION...AS THE SFC-H8 WIND FIELD WILL BECOME MORE UNIDIRECTIONAL
OUT OF THE SOUTH...AND THE ENTIRE WIND PROFILE WILL INCREASE SLIGHTLY
IN SPEED. THE ETA DOES HINT AT AN H8 BOUNDARY ACROSS THE NORTHWEST
HALF OF THE MIDSTATE. OVERALL...THE BEST INGREDIENTS WILL SHIFT
WESTWARD. WE SHOULD SEE AT LEAST SCATTERED ACTIVITY (30-40%) ACROSS
THE WEST...WILL PUT PLATEAU GROUP IN 20% OR 30% CHANCE.

ISOLATED ACTIVITY SHOULD REMAIN TOMORROW EVENING...THEN AS WE MOVE
THROUGH THURSDAY AND THE WEEKEND...THE COOL POOL STAYS WEST OF THE
MIDSTATE AND GRADUALLY MODERATES CREATING NOT AS STEEP LAPSE RATES.
WIND FIELDS STAY UNIDIRECTIONAL...IN THE SOUTHERLY FLOW. AFTER
ANOTHER 30 PERCENT COVERAGE DAY IN THE WEST ON THURSDAY...ALL AREAS
WILL LIKELY SEE JUST ISOLATED ACTION INTO THE WEEKEND.
