255 AM CDT FRI JUN 8 2007

.DISCUSSION...

MAIN FORECAST CONCERNS ARE THUNDERSTORM CHANCES TODAY.

BASED ON LATEST RADAR...MAIN AREA OF CONVECTION EXTENDING FROM
SOUTHWEST MISSOURI INTO CENTRAL ILLINOIS WILL REACH WEST PORTIONS OF
THE PAH FORECAST AREA TOWARD 10Z.  WESTERN PORTIONS OF THE
FA ARE IN TORNADO WATCH 365 UNTIL 12Z.  FORECAST SOUNDINGS SHOW CAP
ERODING ACROSS THE PAH FA BY 12Z...WHICH IS SUPPORTED BY SOME
ISOLATED SHOWERS CURRENTLY TRYING TO DEVELOP IN SOUTHEAST MISSOURI
INTO EXTREME SOUTHERN ILLINOIS.  ANY THUNDERSTORMS THAT DEVELOP OUT
AHEAD OF THE MAIN ACTIVITY SHOULD REMAIN BELOW SEVERE LIMITS.  SPC
CONTINUES TO HAVE THE ENTIRE FA IN A SLIGHT RISK FOR TODAY. THIS
MAIN AREA OF THUNDERSTORMS MAY WEAKEN A LITTLE AS IT MOVES EAST
THROUGH 12Z...BUT THUNDERSTORMS SHOULD REINTENSIFY THIS MORNING WITH
FORECAST LIS ACROSS THE PAH FA OF -3 TO -5.  NAM CONTINUES TO BE A
LITTLE SLOWER WITH THE PASSAGE OF THE COLD FRONT THAN GFS...WITH THE
FRONT STILL ACROSS SOUTHEAST PORTIONS OF THE FA BY 00Z SATURDAY.

BASED ON SLOWER NAM SOLUTION...LINGERED SOME SLIGHT CHANCE POPS
ACROSS SOUTHERN AND SOUTHEAST PORTIONS OF THE FA INTO THIS
EVENING...THEN HIGH PRESSURE BUILDS IN FOR THE WEEKEND.  BOTH NAM
AND GFS SHOW PRECIP JUST TO OUR WEST SUNDAY AFTERNOON.  CONTINUED
WITH DRY FORECAST UNTIL SUNDAY...THEN BACKED OFF SLIGHT CHANCE POPS
FOR JUST THE WESTERN HALF OF THE FA SUNDAY NIGHT AND MONDAY.

FOR TEMPS TODAY...LEANED TOWARD COOLER MET VALUES FOR NORTHWEST HALF
OF FA...AND TOWARD WARMER MAV FOR SOUTHEAST HALF.  FOR THE REST OF
THE NEAR USED MORE OF COMPROMISE OF MAV/MET.  IN THE EXTENDED...MADE
SOME MINOR TWEAKS BASED ON LATEST MEX AND FOR BLENDING PURPOSES.

&&

.AVIATION...
LEADING EDGE OF CONVECTION SHOULD AFFECT KCGI BY 12Z AND KPAH AND
KEVV BY 18Z.  MOST CEILINGS SHOULD BE MVFR...WITH IFR CONDITIONS
WITH CONVECTIVE ACTIVITY ASSOCIATED WITH FRONT.  VFR CONDITIONS WILL
RETURN TONIGHT.
