AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1047 AM CDT MON JUN 26 2006

.UPDATE...
UPPER LOW WITH -17C COLD CORE HAS BEEN SITTING NEARLY STATIONARY
OVER THE QUAD CITIES AREA THROUGH THE MORNING HOURS.  WATER VAPOR
IMAGERY SHOWS A COUPLE VORT LOBES ROTATING THROUGH MISSOURI.

AT THE SURFACE... WEAK TROUGH AND ATTENDANT CONVERGENCE LINE
STRETCHED FROM NEAR KPNT TO JUST EAST OF KDEC AND KSHE.  VISIBLE
SATELLITE IMAGERY SHOWS LINE OF ENHANCED CU/TCU IN THE VICINITY OF
THE CONVERGENCE LINE.  RADAR HAS INDICATED A FEW SHOWERS ASSOCIATED
WITH THIS FEATURE ACROSS SHELBY COUNTY LATE THIS MORNING.

MEANWHILE... LOCATIONS ALONG AND WEST OF THE I-55 CORRIDOR REMAIN
SOCKED IN WITH FAIRLY LOW CEILINGS... UNDER THE INFLUENCE OF UPPER
LOW.  SKIES ARE MOSTLY SUNNY FARTHER EAST... ESPECIALLY ALONG AND
EAST OF THE AFOREMENTIONED CONVERGENCE ZONE.

MADE MINOR ADJUSTMENTS TO THE GOING FORECAST.  LOWERED TEMPS AND
INCREASED CLOUD COVER GRIDS WEST OF I-55 WHERE SKIES WILL LIKELY
REMAIN MOSTLY CLOUDY TO JUST PLAIN OVERCAST THROUGH MUCH OF THE
DAY.  ANY CLEARING/SFC HEATING WILL LIKELY JUST LEAD TO MORE CU
FORMATION GIVEN COOL TEMPS ALOFT.

INCREASED POPS EAST OF I-55 WHERE TEMPS WILL WARM UP INTO THE UPPER
70S/LOWER 80S BY AFTERNOON.  SFC ANALYSIS ALSO SHOWS MORE LOW LEVEL
MOISTURE POOLED UP IN THIS AREA.  OVERALL... LOOKS LIKE SCATTERED
SHOWERS AND THUNDERSTORMS WILL BE A GOOD BET ACROSS MOST OF THE
CWA... WITH BEST COVERAGE IN THE EAST WHERE ATMOSPHERE WILL BECOME
MORE UNSTABLE.  SERIES OF UPPER VORT LOBES WILL ACT AS FOCUSING
MECHANISMS... INCREASING POP COVERAGE LATER THIS AFTERNOON
CONCURRENT WITH THE TIME OF PEAK HEATING.  WITH COOL TEMPS ALOFT...
MARGINAL HAIL STILL APPEARS TO BE THE PRIMARY THREAT FOR ANY SEVERE
WX.

UPDATED ZFP WILL BE OUT IN JUST A BIT.
