Area forecast discussion, May 3, 1:39 PM CDT, 51 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 139 PM CDT MON MAY 3 2010 .DISCUSSION... ISSUED 139 PM CDT MON MAY 3 2010 SHORT TERM...TONIGHT THROUGH THURSDAY... MINI VORT-MAX HAS MOVED INTO CENTRAL ILLINOIS AND HELPED SPARK CONVECTION ALONG A SURFACE BOUNDARY FROM PITTSFIELD TO NORTH OF CHAMPAIGN. COLD POOL ALOFT AND SURFACE HEATING OF BOUNDARY LAYER HAS RESULTED IN FAVORABLE SURFACE-BASED CAPE IN EXCESS OF 1K J/KG. EXPECT HAIL TO BE THE MAIN HAZARD...WITH WIND DAMAGE ALSO POSSIBLE DUE TO THE DRY AIR EVIDENT IN THE 18Z LINCOLN SPECIAL SOUNDING. IN ADDITION...AN ISOLATED TORNADO CANNOT BE RULED OUT VICINITY OF VORT MAX AND NORTH OF THE SURFACE BOUNDARY. THIS ACTIVITY WILL BE MAINLY RESTRICTED TO THE EASTERN COUNTIES AFTER 00Z...AND INTO INDIANA BY 06Z. WILL THEREFORE ONLY HAVE SOME EVENING POPS IN THE EASTERN HALF. REMAINDER OF TONIGHT AND TUESDAY SHOULD BE DRY. NOT ALOT OF COLD AIR WITH THE FRONT NOW MOVING THROUGH...SO HIGH TEMPERATURES SHOULD REBOUND NICELY INTO THE UPPER 70S/LOWER 80S. NEXT COLD FRONT WILL MOVE INTO THE AREA ON WEDNESDAY...THEN TURN STATIONARY JUST TO OUR SOUTH WEDNESDAY NIGHT AND THURSDAY. THE FRONT SHOULD BE IN THE SOUTHEASTERN PART OF THE FORECAST AREA DURING PEAK HEATING WEDNESDAY AFTERNNOON. GFS/NAM MODELS BOTH INDICATE SUFFICIENT MOISTURE AND INSTABILITY ALONG THE FRONT FOR SOME CONVECTIVE INITIATION. UNCERTAINTIES REGARDING TIMING AND COVERAGE PRECLUDE ANYTHING MORE THAN CHANCE POPS FOR NOW. WILL ALSO HAVE SOME SLIGHT CHANCE POPS FOR ANYTHING LINGERING WEDNESDAY EVENING. SURFACE CYCLOGENESIS IS STILL EXPECTED ON THE WESTERN END OF THE FRONT OVER THE CENTRAL OR SOUTHERN PLAINS AS A VIGOROUS UPPER TROUGH EMERGES FROM THE ROCKIES. AS THE LOW MOVES NORTHEAST ALONG THE FRONT...MOISTURE ADVECTION AND ISENTROPIC UPGLIDE WILL INCREASE ALONG AND NORTH OF THE FRONT...SPREADING PRECIPITATION BACK INTO THE AREA. WILL BEGIN INCREASING POPS THURSDAY AND THURSDAY NIGHT WITH THIS SCENERIO IN MIND. LONG TERM...FRIDAY THROUGH MONDAY... SURFACE LOW TO THE WEST WILL MOVE QUICKLY NORTHEASTWARD ALONG THE STATIONARY FRONT THROUGH ILLINOIS ON FRIDAY. THERE SHOULD BE A DECENT CONTRAST IN TEMPERATURES...WITH THE EXTREME NORTHWEST STAYING IN THE 60S AS THE SOUTHEAST WARMS TO AROUND 80. BY FRIDAY AFTERNOON...INCREASING MOISTURE AND INSTABILITY WILL HELP DEVELOP SOME POTENTIALLY STRONG/SEVERE STORMS OVER THE EAST/SOUTHEAST. WILL INDICATE SOME HEALTHY CHANCE POPS FRIDAY...WHICH MAY NEED TO BE BOOSTED UP IF LONGER RANGE MODELS COME IN BETTER AGREEMENT. THE GFS IS A FASTER/WEAKER OUTLIER COMPARED TO THE MORE CONSISTENT DETERMINISTIC AND ENSEMBLE VERSIONS OF THE ECMWF...BUT IT IS BEGINNING TO TREND CLOSER TO THE ECMWF. SATURDAY AND SUNDAY LOOK QUITE COOL AS COLD AIR COMES SOUTHWARD FROM CANADA BEHIND THE DEPARTING LOW. HIGH TEMPERATURES WILL LIKELY BE IN THE 60S...WHILE LOWS IN THE UPPER 30S APPEAR POSSIBLE IN THE NORTH SATURDAY NIGHT. AS THE LARGE CANADIAN SURFACE HIGH MOVES ACROSS THE MIDWEST SUNDAY AND INTO THE EAST MONDAY...RETURN SOUTHEASTERLY LOW LEVEL FLOW BEGINS TO SET UP AS THE NEXT LOW PRESSURE EMERGES FROM THE SOUTHERN ROCKIES. MODELS ARE SUGGESTING ENOUGH MOISTURE AND ISENTROPIC LIFT TO PRODUCE SOME RAIN AS EARLY AS SUNDAY NIGHT AND MONDAY...BUT THE MOISTURE MAY NOT RETURN THAT QUICKLY. FOR NOW WILL PUT IN SOME SLIGHT CHANCE POPS FOR THE SOUTHWEST...BUT THIS IS LOW CONFIDENCE THIS FAR IN ADVANCE. 04 && .AVIATION... ISSUED 1155 AM CDT MON MAY 3 2010 SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS AFTERNOON ACROSS THE CENTRAL IL TERMINALS WITH A COLD FRONT NEAR THE IL RIVER PRESSING INTO SE IL EARLY THIS EVENING AND A SHORT WAVE OVER NE MO MOVING EAST ACROSS CENTRAL IL.
