AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 254 PM CDT TUE JUL 6 2010 .DISCUSSION... ISSUED 254 PM CDT TUE JUL 6 2010 FORECAST CHALLENGES CONTINUE TO FOCUS ON RAIN CHANCES OVER THE NEXT COUPLE OF DAYS...AS A FRONTAL BOUNDARY SLOWLY PUSHES EASTWARD INTO THE AREA. 19Z SURFACE ANALYSIS SHOWS HIGH PRESSURE CENTERED OVER THE SOUTHEAST CONUS...PROVIDING WARM/HUMID SOUTHERLY FLOW INTO CENTRAL ILLINOIS. TO THE WEST...A DIFFUSE FRONTAL BOUNDARY REMAINS STALLED WEST OF THE MISSISSIPPI RIVER...WHILE A STRONGER COLD FRONT IS BEGINNING TO PROGRESS EASTWARD INTO THE UPPER MIDWEST. ALOFT...595DM 500MB RIDGE REMAINS ANCHORED OVER THE MID-ATLANTIC STATES...WHILE A SIGNIFICANT TROUGH DROPS INTO THE NORTHERN ROCKIES. SHORT TERM...TONIGHT THROUGH FRIDAY WEAK SHORT-WAVE EVIDENT ON WATER VAPOR IMAGERY ACROSS EASTERN KANSAS/WESTERN MISSOURI HAS TRIGGERED SCATTERED SHOWERS AND THUNDERSTORMS FROM CENTRAL MISSOURI NORTHEASTWARD INTO WEST-CENTRAL ILLINOIS. THIS ACTIVITY IS DRIFTING N/NE AND WILL IMPACT THE ILLINOIS RIVER VALLEY THROUGH THE EVENING HOURS. AS HAS BEEN THE CASE OVER THE PAST FEW DAYS...CONVECTION WILL LARGELY BE DIURNAL IN NATURE AND WILL TEND TO DISSIPATE OVERNIGHT. 12Z MODELS SHOW THIS TREND QUITE NICELY...WITH QPF COVERAGE DIMINISHING AFTER MIDNIGHT. BASED ON LATEST RADAR MOSAIC...WILL INCLUDE CHANCE POPS FOR SCATTERED SHOWERS/STORMS ALONG AND WEST OF THE ILLINOIS RIVER...WITH ISOLATED MENTION FURTHER EAST TO THE I-55 CORRIDOR. SAME GENERAL SYNOPTIC PATTERN WILL BE IN PLACE ON WEDNESDAY...WITH MAIN FORCING ALONG WEAKENING FRONTAL BOUNDARY REMAINING TO THE WEST OF THE MISSISSIPPI RIVER. ADDITIONAL TROPICAL MOISTURE FROM AN UPPER LOW CURRENTLY SPINNING ACROSS LOUISIANA WILL BECOME ENTRAINED INTO THE MAIN PLUME OF MOISTURE AROUND THE SOUTHEAST CONUS RIDGE. THIS EXTRA PUSH OF MOISTURE SHOULD HELP ENHANCE THE COVERAGE OF AFTERNOON THUNDERSTORMS ON WEDNESDAY...ESPECIALLY ACROSS THE WESTERN KILX CWA. HAVE THEREFORE INCREASED POPS INTO THE CHANCE CATEGORY FOR AREAS ALONG AND WEST OF I-55...WHILE MAINTAINING A HOT AND DRY FORECAST FURTHER EAST ACROSS EAST-CENTRAL AND SOUTHEAST ILLINOIS. STRONG UPPER-WAVE OVER THE NORTHERN ROCKIES WILL TRACK INTO THE UPPER MIDWEST WEDNESDAY NIGHT...PUSHING A COLD FRONT SOUTHEASTWARD TOWARD CENTRAL ILLINOIS. GIVEN STRENGTH OF UPPER RIDGING TO THE E/SE...BOUNDARY WILL LIKELY REMAIN NORTHWEST OF THE AREA UNTIL THURSDAY. AS SUCH...WILL KEEP THE E/SE CWA DRY WEDNESDAY NIGHT. FURTHER WEST...WILL RAMP POPS UP TO LIKELY WEST OF THE ILLINOIS RIVER...DUE TO THE ENHANCED MOISTURE FROM THE LOUISIANA UPPER LOW AND THE CLOSER PROXIMITY TO THE BEST FORCING ALONG THE ADVANCING FRONT. BEST RAIN CHANCES WILL ARRIVE ON THURSDAY...AS BOUNDARY PUSHES INTO CENTRAL ILLINOIS. WITH PRECIPITABLE WATER VALUES HOVERING AROUND 2 INCHES AND GOOD CONVERGENCE ALONG THE FRONT...EXPECT WIDESPREAD SHOWERS AND THUNDERSTORMS. HAVE INCREASED POPS TO LIKELY ACCORDINGLY. GENERAL TIMING OF FROPA REMAINS VIRTUALLY UNCHANGED FROM PREVIOUS FORECASTS...WITH A SLIGHT INCREASE IN SPEED NOTED FOR FRIDAY. WILL MAINTAIN RAIN CHANCES ACROSS THE BOARD THURSDAY NIGHT...THEN WILL CUT BACK TO JUST THE EASTERN TWO-THIRDS OF THE AREA FOR FRIDAY. LONG TERM...SATURDAY THROUGH TUESDAY HIGH PRESSURE WILL BUILD INTO THE REGION OVER THE WEEKEND...PROVIDING SLIGHTLY COOLER AND LESS HUMID CONDITIONS. WITH 850MB TEMPS DROPPING INTO THE 15 TO 18C RANGE...AFTERNOON HIGHS WILL RETURN TO NEAR NORMAL FOR THIS TIME OF YEAR IN THE MIDDLE 80S. MEDIUM RANGE MODELS ARE INDICATING A ZONAL FLOW PATTERN SETTING UP ACROSS THE CONUS FOR MUCH OF NEXT WEEK...WHICH WOULD RESULT IN A CONTINUATION OF SEASONABLE TEMPERATURES. NEXT FRONTAL BOUNDARY APPEARS TO BE ARRIVING SOMETIME DURING THE MONDAY/TUESDAY TIME FRAME...WITH BOTH GFS AND ECMWF SUGGESTING A RATHER PROGRESSIVE NATURE TO THE FRONT. WITH AMPLE MOISTURE RETURN LATE IN THE WEEKEND AHEAD OF THE APPROACHING SYSTEM...HAVE ADDED RAIN CHANCES TO THE FORECAST FOR MONDAY. BARNES && .AVIATION... ISSUED 1255 PM CDT TUE JUL 6 2010 VFR CONDITIONS SHOULD PREVAIL FROM I-55 EAST THROUGH 18Z/1 PM WED. MVFR CONDITIONS ARE POSSIBLE WEST OF THE IL RIVER AT PIA WITH SHOWERS AND ISOLATED THUNDERSTORMS FROM 20Z-01Z (3-8 PM) WHICH ARE CURRENTLY MOVING NE ACROSS MO TOWARD QUINCY AND PITTSFIELD.

JUST SCATTERED CUMULUS CLOUDS 4-7K FT THIS AFTERNOON AND AGAIN BY MIDDAY WED. STRONG UPPER LEVEL RIDGE SHOULD KEEP FRONTAL BOUNDARY OVER CENTRAL WI/IA AND EASTERN KS WEST OF IL THROUGH WED.
