AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
140 PM CDT THU JUN 22 2006

.DISCUSSION...
SEVERAL CONCERNS WITH THIS FORECAST PACKAGE.  FIRST IS POPS INTO THE
WEEKEND...AND EFFECT ON TEMPERATURES. THEN HOW MUCH IMPACT WILL
EVENTUAL FRONTAL PASSAGE HAVE ON TEMPERATURES AND DEWPOINTS.
LASTLY...THE CHC OF PRECIPITATION NEXT WEDNESDAY AND THURSDAY.

AS UPPER LEVEL ENERGY APPROACHES THE REGION FROM THE WEST AND
NORTHWEST THIS AFTERNOON...STRONG TO SEVERE THUNDERSTORMS HAVE BEGUN
TO DEVELOP RAPIDLY IN VERY MOIST AND UNSTABLE AIRMASS. EXPECT
ACTIVITY TO INCREASE THE REST OF THE AFTERNOON AND INTO THE EVENING
HOURS.

IN THE MEANTIME...A WEAK COLD FRONT POISED NORTH AND WEST OF OUR CWA
WILL BEGIN TO MAKE PROGRESS (ALBEIT SLOW) TO THE SOUTH AND EAST ON
FRIDAY AS THE FLOW ALOFT VEERS AROUND TO THE NORTHWEST. THE
COMBINATION OF THE FRONTAL PASSAGE AND THE MOIST AND UNSTABLE
AIRMASS REMAINING IN PLACE SHOULD PRODUCE ANOTHER ROUND OF SHOWERS
AND THUNDERSTORMS. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO TAPER
OFF FROM NORTHWEST TO SOUTHEAST FRIDAY EVENING...AND BE CLEAR OF THE
CWA AFTER MIDNIGHT.

HIGH PRESSURE SHOULD KEEP THE REGION SLIGHTLY COOLER..DRY...AND LESS
HUMID THROUGH TUESDAY NIGHT. MODELS DO SWING AN UPPER TROF ACROSS
THE REGION ON MONDAY BUT MOISTURE WILL BE LIMITED...SO WILL KEEP DRY
AT THIS TIME.

BY THE MIDDLE OF NEXT WEEK MODELS PUSH A COLD FRONT INTO THE REGION
WITH THE APPROACH OF AN UPPER LEVEL SHORT WAVE. WITH UPPER FLOW
EXPECTED TO BE NEARLY PARALLEL TO THE FRONT...ITS SOUTHWARD PROGRESS
WILL BE SLOW. THEREFORE...HAVE PUT IN SCHC POPS FOR WEDNESDAY...
WEDNESDAY NIGHT...AND THURSDAY.
