AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
310 PM CDT THU JUN 10 2004

.DISCUSSION...
SHORT TERM...TONIGHT THROUGH SUNDAY
ALTHOUGH MAIN WARM FRONT IS STILL WELL TO OUR NORTH...A PSEUDO WARM
FRONT HAS SET UP OVER CENTRAL ILLINOIS ON THE DIFFERENTIAL HEATING
BOUNDARY FROM THIS MORNINGS RAIN. THIS HAS BECOME A PLAYER IN
EVENING CONVECTION AS STORMS ARE DEVELOPING IN THE INCREASING
UNSTABLE AIRMASS ALONG AND SOUTH OF I-72. IN ADDITION...WATER VAPOR
LOOPS INDICATE THE NEXT IN A SERIES OF SHORTWAVES IS ENTERING
SOUTHWEST MISSOURI...AND THIS FEATURE WILL LIKELY SUPPORT MORE
PRECIPITATION LATER TONIGHT. WILL HAVE LIKELY POPS OVER MOST OF THE
CWA...TRENDING TO 30 POPS IN THE SOUTHEAST.

THE ETA AND GFS ARE COMING MORE INTO AGREEMENT WITH THE PLACEMENT OF
THE SYNOPTIC FRONT...AND IS STILL EXPECTED TO BE TO OUR NORTH ON
FRIDAY. CONDITIONS TOMORROW MAY BE SIMILAR TO TODAY...WITH LINGERING
MORNING PRECIPITATION FROM OVERNIGHT ACTIVITY AND REGENERATION ALONG
ANY MESOSCALE BOUNDARIES. AIRMASS IS STILL EXPECTED TO BE RELATIVELY
UNSTABLE AND ONLY WEAKLY CAPPED. ALTHOUGH THE HIGH PRECIPITABLE
WATER VALUES WILL ACT TO INHIBIT ORGANIZED SEVERE WEATHER...VERY
HEAVY RAINFALL WILL BE POSSIBLE FROM ANY AFTERNOON CONVECTION THAT
CAN DEVELOP. WILL CARRY 30S POPS EVERYWHERE FRIDAY AND FRIDAY NIGHT
DESPITE THE WARM FRONT BEING TO OUR NORTH.

SATURDAY AND SATURDAY NIGHT EXPECTED TO BE A LULL PERIOD AS THE
STRONG PLAINS SYSTEM BACKS THE UPPER FLOW AND MAIN ZONE OF LIFT
SHIFTS WESTWARD. THIS WAVE IS FORECAST TO MOVE INTO THE MIDWEST
BEGINNING SUNDAY...WITH THE ATTENDING COLD FRONT MOVING THROUGH
SUNDAY NIGHT. WITH THIS IN MIND...WILL KEEP HEALTHY CHANCE POPS
GOING ACROSS THE AREA. SUNDAY NIGHT MAY NEED TO BE BUMPED UP TO
LIKELY IF THE CURRENT TIMING HOLDS UP.

LONG TERM...MONDAY THROUGH THURSDAY
BY 12Z MONDAY...THE FRONT IS EXPECTED TO LIE ACROSS EASTERN
ILLINOIS...WITH DRIER AIR INVADING FROM THE WEST. CURRENT FORECASTS
HAVE MORNING POPS IN THE EAST ON MONDAY...AND SEE LITTLE REASON TO
MAKE ANY BIG CHANGES.

YESTERDAYS GFS RUN HAD A DECENT SHORTWAVE MOVING ACROSS THE AREA ON
WEDNESDAY...AND THIS MORNINGS RUN HAS BACKED OFF FROM THIS SCENERIO.
WILL HOLD OFF ON ANY MAJOR CHANGES IN THE EXTENDED PERIODS UNTIL THE
