AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 300 PM CDT FRI JUN 4 2010 .DISCUSSION... ISSUED 300 PM CDT FRI JUN 4 2010 SHORT TERM...TONIGHT THROUGH MONDAY... MAIN FORECAST ITEM IN THE SHORT TERM WILL BE THE POTENTIAL FOR SEVERE WEATHER AND EXCESSIVE RAINFALL TONIGHT AND SATURDAY. LEAD IMPULSE IS MOVING ACROSS ILLINOIS AT THIS TIME...HOWEVER 18Z SOUNDING DATA FROM LINCOLN INDICATES THE BASE OF A WARM CAPPING LAYER AT ABOUT 5KFT. ON JUST SURFACE HEATING ALONE...THIS CAP WOULD HOLD PRETTY STRONG. HOWEVER...SURFACE ANALYSIS SHOWS A CONFLUENT ZONE FROM NORTHEASTERN MISSOURI INTO NORTH-CENTRAL ILLINOIS. MECHANICAL LIFT ALONG THIS BOUNDARY MAY BE SUFFICIENT FOR BOUNDARY LAYER PARCELS TO REACH THE LEVEL OF FREE CONVECTION. THUNDERSTORM DEVELOPMENT WOULD THEN PRETTY RAPID GIVEN MLCAPES 2000-2500 J/KG AND EFFECTIVE BULK SHEAR OF 35-40 KT. WITH THESE FACTORS IN MIND...WILL GO WITH LIKELY POPS OVER THE NORTHWEST THIS EVENING. THE EXPECTED STORMS WILL THEN CONSOLIDATE INTO AN MCS WHICH WILL TRACK ACROSS THE NORTHERN THIRD OF THE STATE OVERNIGHT. MEANWHILE...ANOTHER CONVECTIVE COMPLEX IS FORECAST TO DEVELOP LATER TONIGHT FURTHER WEST OVER EASTERN NEBRASKA/KANSAS AND COME EASTWARD OVERNIGHT. THIS ACTIVITY WILL PROBABLY HOLD TOGETHER AS IT ENTERS NORTH-CENTRAL ILLINOIS BY 12Z SAT. SEVERE WEATHER WILL ALSO BE LIKELY WITH THIS FEATURE...ALONG WITH AN INCREASING THREAT FOR HEAVY RAINFALL. FLASH FLOOD GUIDANCE VALUES OVER SOME COUNTIES OF NORTH-CENTRAL ILLINOIS ARE AROUND 2 INCHES WITHIN 6 HOURS...WHICH WILL BE WITHIN REACH CONSIDERING THE UPPER FLOW PARALLEL TO THE LOW LEVEL FORCING ALONG WITH THE MULTIPLE HITS FROM AT LEAST 2 CONVECTIVE SYSTEMS. WILL ISSUE A FLASH FLOOD WATCH FOR FULTON- TAZEWELL-MCLEAN COUNTIES AND NORTHWARD FOR 12Z SAT TIL 00Z SUN. TIMES MAY NEED TO BE ADJUSTED DEPENDING ON HOW FAR WEST THE STORMS DEVELOP OVERNIGHT...OR IF THEY LINGER LONGER THAN EXPECTED SATURDAY EVENING. A BRIEF BREAK FROM THE ACTIVE WEATHER WILL ARRIVE FOR SUNDAY THROUGH MONDAY AS THE EFFECTIVE SURFACE BOUNDARY DRIFTS TO THE SOUTH OF CENTRAL ILLINOIS. LONG TERM...TUESDAY THROUGH FRIDAY... ON TUESDAY...A SURFACE LOW IS FORECAST TO DEVELOP OVER THE CENTRAL PLAINS ALONG THE TAIL END OF THE STALLED OUT FRONT TO OUR SOUTH. THIS LOW WILL THEN MIGRATE EASTWARD PROVIDING ANOTHER SHOT AT PRECIPITATION BEGINNING PERHAPS MONDAY NIGHT BUT MORE LIKELY TUESDAY THROUGH WEDNESDAY. THIS WILL PROVIDE ANOTHER OPPORTUNITY FOR HEAVY RAINFALL DEPENDING ON THE ORIENTATION OF THE SURFACE FRONT AND HOW FAR NORTH IT GETS. AFTER THAT...THE 12Z ECMWF AND GFS ARE NOW IN AGREEMENT THAT UPPER TROUGHING WILL INCREASE OVER THE NORTHEAST... WHICH SUGGESTS A DECENT HIGH PRESSURE SYSTEM WITH DRIER AIR FOR THURSDAY AND FRIDAY. 04 && .AVIATION... ISSUED 1245 PM CDT FRI JUN 4 2010 ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS POSSIBLE FROM MID AFTERNOON UNTIL SUNSET ACROSS THE CENTRAL IL AIRPORT TERMINALS WITH CEILINGS AND VISIBILITIES LOWERING TO MVFR CATEGORY IF THEY OCCUR.
