817 PM CDT TUE JUN 15 2010

.MESOSCALE UPDATE...
MODELS/LAPS SHOWS A FEW STRONG-SVR STORMS POSSIBLE NW MID TN THIS
EVENING W/LKLY POPS. WW#321 SET TO EXPIRE AT 02Z. NO WATCHES
PLANNED AS FAR SOUTH AS N MID TN THIS EVENING.

.PREV DISCUSSION... /ISSUED 229 PM CDT TUE JUN 15 2010/

DISCUSSION...
ANALYSIS SHOWING SFC LOW IN THE UPPER MID-WEST...WITH ASSOCIATED
NEARLY STATIONARY CDFNT DOWN INTO THE PLAINS AND WMFNT UP ACROSS
THE OH VALLEY. THE MID-SOUTH REMAINS IN VERY WARM/HUMID SECTOR
WITH UL RIDGE AND SFC HIGH IN CONTROL. SCT CONVECTION BREAKING OUT
ALL OVER THE REGION BUT IS STILL MINIMAL IN THE CWA.

WEAK UL TROUGH ALONG WITH SFC LOW SET TO CROSS THE MID-WEST/GREAT LAKES
THROUGH WED...PUSHING CDFNT TO JUST NORTHWEST OF THE CWA BY 12Z WED
THEN SEEMINGLY STALLING IT CLOSE TO THERE THROUGH 00Z THU. SOME QUESTION
REMAINS ON HOW FAR SOUTH IT WILL SINK AFTER THAT POINT BUT GFS REMAINS
MORE AGGRESSIVE DROPPING DEW INTO THE UPR 50S ON THU AFTERNOON. REALLY
HARD TO TELL HOW FAR SOUTH IT WILL GO BUT ML/UL TROUGH DOES BECOME MORE
PRONOUNCED ALONG THE EAST COAST LATE THU. ULTIMATELY FRONTAL BOUNDARY
EXPECTED TO INCREASE CONVECTION TONIGHT...POSSIBLY WITH MCS MOVING JUST
NORTH LATE...AND ON INTO WED AS WELL...AS MOISTURE/INSTABILITY
REMAIN PLENTIFUL. AS FOR WED NIGHT/THU...HARD TO BELIEVE THAT MUCH
DRYING WILL OCCUR SUCH THAT AT LEAST ISO STORMS WONT FORM...ESPECIALLY
SOUTH WHERE DECAYING BOUNDARY MAY BE PRESENT.

REMNANTS OF FRONTAL BOUNDARY MAY HANG AROUND THE VICINITY INTO THE
WEEKEND BUT OVERALL...THE MID-SOUTH DROPS INTO MORE OF A TYPICAL
SUMMERTIME DIURNAL CONVECTION PATTERN AS UPR RIDGE AND BERMUDA HIGH
LOOKING TO BE MAIN FACTORS. TEMPS LIKELY TO STAY ABOVE SEASON NORMALS
THROUGH THE PERIOD.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
