AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
250 PM CDT MON JUL 3 2006

.DISCUSSION...
SHORT TERM...TONIGHT THROUGH WEDNESDAY...
AIRMASS OVER NORTHERN ZONES HAS BECOME QUITE UNSTABLE THIS AFTERNOON
WHERE LOW LEVEL MOISTURE IS POOLING ALONG AND SOUTH OF A
DIFFERENTIAL HEATING BOUNDARY FROM ONGOING CONVECTION. EXPECT
THUNDERSTORMS TO EXPAND AND BECOME SURFACE-BASED SHORTLY...WITH THE
POTENTIAL FOR WIND DAMAGE. ADDITIONAL DEVELOPMENT WILL ALSO BE
POSSIBLE OVER CENTRAL AREAS AS STORMS OVER NORTHEASTERN MISSOURI
INTENSIFY AND MOVE EAST. VISIBLE SATELLITE ALSO SHOWS STREAKS OF
CUMULUS STREAMING INTO SOUTHERN ILLINOIS WHERE SURFACE TEMPERATURES
ARE IN THE MIDDLE 90S. WILL GO WITH CATEGORICAL/LIKELY POPS IN THE
NORTH AND CENTRAL AREAS TONIGHT...WITH JUST SCATTERED OR ISOLATED
ACTIVITY IN THE SOUTHEAST AWAY FROM THE BEST UPPER SUPPORT AND WIND
FIELDS.

THE MAIN SYNOPTIC FRONT WILL SAG INTO THE AREA ON TUESDAY...WITH
PLENTY OF CONVECTIVE DEBRIS AROUND...MUCH LIKE WHAT IS HAPPENING
ACROSS IOWA AND NORTHERN ILLINOIS TODAY. THE MOST CONCENTRATED AREAS
FOR NEW DEVELOPMENT WILL BE ALONG AND AHEAD OF THE FRONT...WHICH
SHOULD BE ACROSS THE MIDDLE OF ILLINOIS AT MIDDAY. AGAIN...LIKELY
POPS SEEM REASONABLE AHEAD OF THE FRONT.  AFTER THAT...DRIER AIR
WILL SLOWLY FILTER INTO THE FORECAST AREA TUESDAY NIGHT AND
WEDNESDAY. WILL GO AHEAD AND LINGER A SLIGHT CHANCE POP IN THE
SOUTHEAST WEDNESDAY MORNING AS THE FRONT SHOULD MAKE SLOWER PROGRESS
AS IT PUSHES SOUTH OF THE BELT OF WESTERLIES ALOFT.

LONG TERM...THURSDAY THROUGH MONDAY...
SHORTWAVE ENERGY THAT ROTATES AROUND THE UPPER TROUGH OVER THE
NORTHEASTERN CONUS LATE WEDNESDAY AND THURSDAY SHOULD PRODUCE NO
PRECIPITATION OVER THE FORECAST AREA. MODELS INDICATE THE LIFT IS
WEAK/SHALLOW AND WILL PROBABLY BE INSUFFICIENT TO ACTIVATE ANY OF
THE LINGERING MEAGER MOISTURE THAT MAY BE AROUND...ESPECIALLY THIS
FAR TO THE SOUTHWEST.

REMAINDER OF THE LONGER TERM FORECAST SHOULD BE QUIET. THE MAIN
FORECAST ISSUE IS HOW LONG THE MEAN UPPER RIDGING WILL HOLD OVER THE
WESTERN/CENTRAL STATES. FOR THIS...ATTENTION IS TURNED TO THE
PACIFIC NORTHWEST WHERE THE GFS IS MUCH MORE AGRESSIVE IN LOWERING
THE HEIGHTS AND CAUSING THE DOWNSTREAM RIDGE TO PUSH EASTWARD. THE
ECMWF IS WEAKER WITH THE NORTHWESTERN TROUGH AND HOLDS ONTO RIDGING
OVER THE CENTRAL STATES LONGER. THE ECMWF IS MORE CONSISTENT AND
MORE CLIMATOLOGICALLY SOUND BASED ON TELECONNECTIONS...AND THE GFS
HAS BEGUN TO TREND SLOWER AND SLOWER. THIS MEANS THAT THE FRONT THAT
THE GFS BRINGS INTO THE MIDWEST ON MONDAY WILL LIKELY BE SLOWER.
WILL THEREFORE CONTINUE WITH THE DRY FORECAST THURSDAY THROUGH
MONDAY.
