AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
218 PM CDT FRI JUL 21 2006

.DISCUSSION...

MAIN CONCERNS ARE CONVECTIVE POTENTIAL OVER THE FIRST 24 HOURS.

THE COLD FRONT IS CURRENTLY POSITIONED JUST NORTHWEST OF THE
CWA...WHILE MAIN MID-LEVEL TROUGH WAS LOCATED FURTHER NORTHWEST OVER
SOUTHEAST IOWA AND NORTHWEST MISSOURI.  ONGOING CONVECTION WILL RUN
ITS COURSE THIS AFTERNOON...WITH PRIMARY WIND DAMAGE THREAT ACROSS
THE EVANSVILLE TRI STATE AREA THIS AFTERNOON...WITH HEAVY RAIN MORE
OF A PROBLEM IN TRAILING BAND OF CONVECTION ACROSS THE SOUTHERN TIP
OF ILLINOIS.  LARGE OUTFLOW BOUNDARY FROM THIS CONVECTION WILL
LIKELY SCOUR OUT THE AIRMASS OVER ALL BUT FAR WESTERN COUNTIES IN
SOUTHEAST MISSOURI.

MODELS ARE OF LITTLE USE TODAY...SO WILL HAVE TO GO IT ALONE FOR
TONIGHT.  IN THE WAKE OF THIS AFTERNOONS CONVECTION THERE WILL BE A
WEDGE OF UNSTABLE SURFACE AIR LEFT OVER SOUTHEAST MISSOURI...AHEAD
OF THE COLD FRONT THAT IS EXPECTED TO CONTINUE SLOWLY SOUTHEAST.
SEEING NO SIGN OF NEW CONVECTION TO THE NORTHWEST OVER NORTHERN
MISSOURI...DO NOT THINK MUCH OF THE POTENTIAL FOR ANOTHER ROUND OF
CONVECTION DEVELOPING ON THE HEELS OF THE ONGOING STUFF.

WILL TRY TO FOCUS CONVECTIVE POTENTIAL OVER WESTERN ZONES
TONIGHT...WITH A MORE GENERAL PRECIPITATION THREAT OVER THE
REMAINDER OF THE AREA...SIMILAR TO WHAT IS GOING ON OVER NORTHERN
ILLINOIS RIGHT NOW.  MAY TWEAK POPS DOWN TO LIKELY FOR TONIGHT...BUT
WILL NOT MAKE ANY RADICAL CHANGES AT THIS TIME.  THERE WILL LIKELY
BE SEVERAL UPDATES THROUGH THE EVENING TO DEAL WITH THE WATCH AND
LATEST CONVECTIVE TRENDS.

THE PRIMARY AREA OF PRECIPITATION SHOULD BE OUT OF THE AREA BY 12Z
SATURDAY...BUT THERE WILL BE SOME POTENTIAL FOR AN ISOLATED SHOWER
OR THUNDERSTORM IN THE EASTERN HALF OF THE AREA...MAINLY EARLY
SATURDAY.  WILL LEAVE THE 20-30 POPS GOING FOR SATURDAY.

NO SIGNIFICANT CHANGES BEYOND SATURDAY.
