200 PM EDT SUN AUG 7 2005

.SHORT TERM (TONIGHT AND MONDAY)...

TONIGHT...

ZONAL UPPER AIR FLOW WILL CONTINUE ACROSS SOUTHERN CANADA. A BROAD
UPPER RIDGE WILL PERSIST ACROSS MUCH OF THE CONUS. AN UPPER LOW WILL
CONTINUE TO MOVE SLOWLY NORTHWARD THROUGH EASTERN ALABAMA. EXTENSIVE
MIDLEVEL CLOUDINESS TO THE NORTH OF UPPER LOW WILL MAKE SLOW
PROGRESS NORTHWESTWARD...POSSIBLY GIVING OUR SOUTHEASTERN COUNTIES A
MOSTLY CLOUDY NIGHT AND A FEW OVERNIGHT SHOWERS. FARTHER NORTHWEST
ACROSS SOUTHERN INDIANA...ISOLATED TO SCATTERED EVENING
THUNDERSTORMS WILL DIMINISH OVERNIGHT AND MOSTLY CLEAR SKIES WILL
DEVELOP DURING THE EARLY MORNING HOURS. EVENING STORMS WILL...LIKE
THE PAST SEVERAL DAYS...BE QUITE SLOW MOVING. ISOLATED AREAS MAY
RECEIVE GUSTY WINDS AND BRIEF HEAVY RAINFALL.

MONDAY...

OUR PERSISTENT STAGNANT HUMID AIRMASS WILL CONTINUE ACROSS THE LOWER
OHIO VALLEY MONDAY. ALTHOUGH A WEAK TROUGH WILL MOVE TOWARDS THE
WESTERN GREAT LAKES LATE...THIS FEATURE WILL STAY TOO FAR NORTH TO
AFFECT REGION. ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED TO
DEVELOP AGAIN IN THE AFTERNOON. HAVE NOT NOTED ANY FEATURES TO
DETERMINE MOS LIKELY LOCATION FOR DEVELOPMENT HOWEVER. STRONG
STORM(SHOULD ANY FORM AT ALL) ARE MORE LIKELY ACROSS SOUTHERN
INDIANA AWAY FROM THE POSSIBLE MID LEVEL CLOUDINESS AND MOIST
ADIABATIC LAPSE RATES ASSOCIATED WITH UPPER LOW TO OUR SOUTH.
FORECAST SOUNDING DO INDICATE DRIER AIR AT MID LEVELS ACROSS
INDIANA AND ILLINOIS TOMORROW.

.LONG TERM (MON NIGHT-SUNDAY)...

BROAD UPPER TROFINESS REMAINS OVER THE OHIO VALLEY TUE/WED...LEADING
TO DIURNAL CHANCES FOR TSRA DURING THE AFTN/EVE HOURS. LATEST NAM
DEPICTS A SFC TROF AXIS OVER THE CWA WHICH COULD HELP FOCUS
CONVECTIVE DEVELOPMENT. WET MICROBURST INDEX DOES INDICATE POTENTIAL
FOR SOME ISLTD PULSE-TYPE SVR STORMS ALONG/N OF THE OHIO RIVER TUE
AFTN AND A SIMILAR SITUATION FOR WED AFTN.

THU-SAT PERIOD BOTH GFS/ECMWF FCST FAIRLY STRONG UPPER RIDGING TO
OVERSPREAD MUCH OF THE ERN/SERN CONUS INCLUDING THE OHIO VALLEY.
RELIED HEAVILY ON CLIMATOLOGY FOR THE FCST DURING THIS PERIOD WHICH
YIELDS M/CLEAR NIGHTS AND M/SUNNY TO OCNL PARTLY SUNNY DAYS. ECMWF
850MB RH FIELDS SUPPORT THIS GENERAL THINKING. CHANCES FOR SEEING
THIS YEARS PERSEIDS EARLY FRIDAY MORNING LOOK GOOD AT THIS POINT.
KEPT POPS OUT OF THE FCST FOR THIS PERIOD...THOUGH THURSDAY MIGHT BE
THE DAY WE COULD STILL SEE SOME ISLTD AFTN/EVE CONVECTION AS THE
RIDGE WOULD HAVE YET TO ESTABLISH ITSELF.

SUNDAY A FRONTAL ZONE MAY DEVELOP FROM THE CNTRL PLAINS INTO THE
GREAT LAKES. SUSPECT STRONG RIDGING OVER SERN CONUS WOULD HELP KEEP
THIS FEATURE WELL NW OF THE FCST AREA AT THIS TIME...HWVR HAVE
INCREASED CLOUD COVER FOR SUNDAY AFTN.

TEMPERATURES WILL EXHIBIT A WARMING TREND DURING THE LONG TERM
PERIOD...ESP AS WE GET INTO THU-SAT TIMEFRAME. LOWER TO POSSIBLY MID
90S LOOK REASONABLE...THOUGH DEWPOINTS SHOULD REMAIN AROUND OR
SLIGHTLY BELOW 70F...WHICH WOULD HELP LIMIT PEAK HEAT INDEX READINGS
TO 100F OR BELOW.
