Area forecast discussion, Sep 9, 2:29 PM CDT, 4 hours 23 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 229 PM CDT SAT SEP 9 2006 .DISCUSSION... SHORT TERM...TONIGHT THROUGH WEDNESDAY... COLD FRONT MAKING SLOW PROGRESS THROUGH NORTHERN ILLINOIS THIS AFTERNOON AND NOW LIES FROM NEAR GALESBURG TO SOUTH OF KANKAKEE. EXPECT THIS SLOW MOTION TO CONTINUE THIS EVENING AS THE MAIN UPPER ENERGY APPROACHES FROM THE CENTRAL PLAINS. AREA OF SHOWERS NOW APPROACHING MISSISSIPPI RIVER...BUT WITH UPPER FLOW BACKING AHEAD OF THE KANSAS SHORTWAVE...EXPECT MOST OF THIS ACTIVITY TO BE OVER THE NORTHERN ZONES OVERNIGHT. COVERAGE IS PRETTY GOOD OVER MISSOURI THIS AFTERNOON...BUT THIS MAY DECREASE AS IT EXTENDS INTO INITIALLY DRIER AIR FURTHER EAST. SO WILL GO WITH HEALTHY CHANCE POPS OVER THE NORTH...WITH MORE SCATTERED/ISOLATED ACTIVITY FURTHER SOUTH. OVER THE CENTRAL AREAS SOUTH OF THE FRONT...HEATING INTO THE MIDDLE 80S HAS ONCE AGAIN ALLOWED SOME ISOLATED SHOWERS TO DEVELOP LIKE THE PAST COUPLE OF DAYS. THIS SHOULD DISSIPATE EARLY...THEN POSSIBLY INCREASE ONCE AGAIN OVERNIGHT. PRECIPITATION SHOULD BE INCREASING SUNDAY WITH THE FRONT IN THE AREA AND INCREASING DYNAMICS FROM THE SHORTWAVE THAT WILL BE IN IOWA AND MISSOURI BY THE END OF THE DAY. STILL PREFER THE NAM WITH ITS MASS FIELDS AS THE GFS CONTINUES TO PRODUCE TOO MUCH LOW PRESSURE TOO FAR NORTH. THE BEST BAROCLINIC ZONE AND LIFT SUNDAY AND SUNDAY NIGHT WILL BE ACROSS THE NORTHERN HALF OF THE AREA...WHERE WE WILL INSERT SOME LIKELY POPS. ISOLATED CONVECTION CANNOT BE RULED OUT...BUT MOST OF THE ACTIVITY WILL BE ELEVATED. MONDAY LOOKS LIKE THE BEST CHANCES FOR RAIN...AS THE LEAD SHORTWAVE WILL BE MOVING THROUGH AT THAT TIME. AGAIN...THE NAM LOOKS BETTER IN MOVING A WEAK SURFACE LOW ACROSS SOUTHERN ILLINOIS DURING THE AFTERNOON AND EVENING HOURS. THE NAM CONTINUES TO HAVE SUPPORT FROM THE ENSEMBLE MEANS AS WELL AS THE CANADIAN MODEL. THE GFS WITH ITS STRONG LOW OVER CHICAGO BY 00Z TUESDAY HAS BEEN DISCOUNTED. THE PRECIPITATION WILL BEGIN TO MOVE EAST OF THE AREA TUESDAY...WITH ONLY A SLIGHT CHANCE OF SOME LINGERING SHOWERS OVER THE EAST TUESDAY NIGHT. LONG TERM...THURSDAY THROUGH SATURDAY... THE LONGER TERM WILL SEE A WARMING TREND BEGINNING LATE THURSDAY INTO SATURDAY AS UPPER TROUGHING DEVELOPS OVER THE PACIFIC NORTHWEST AND THE NEXT COLD FRONT MOVES INTO THE WESTERN PLAINS. WARM ADVECTION AHEAD OF THE FRONT WILL BRING HIGHS ONCE AGAIN INTO THE LOWER 80S FRIDAY AND SATURDAY. THE FRONT WILL BE SLOW TO MOVE THROUGH THE PLAINS AND EXPECT THE NEXT CHANCE FOR PRECIPITATION TO BE BEYOND THIS 7 DAY PERIOD. && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. && 04
