NWS Lincoln, IL wrote its last area forecast discussion before the first event at May 25, 1:50 PM CST, 3 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 250 PM CDT FRI MAY 25 2007 .DISCUSSION... ISSUED 249 PM CDT FRI MAY 25 2007 LATEST SURFACE ANALYSIS HAD A NEARLY STATIONARY FRONTAL BOUNDARY ACROSS SOUTHERN ILLINOIS FROM JUST SOUTH OF ST LOUIS MO TO THE VICINITY OF DANVILLE. FRONT IS REALLY NOT TO HARD TO FIND AT THE MOMENT WITH THE CONVECTION FIRING ALONG IT. THIS FRONT WILL BE THE PRIMARY FOCUS FOR SHOWERS/STORMS THROUGH SATURDAY...WITH ANOTHER FRONT THAT WILL BE DROPPING OUT OF THE PLAINS A FOCUS FOR STORMS SATURDAY NIGHT INTO MONDAY. PRIMARY FORECAST CONCERN IS TRYING TO PINPOINT LOCATION/TIMING OF SHOWERS/STORMS OVER NEXT FEW DAYS IN A VERY UNSETTLED PATTERN. 12Z MODELS IN GOOD OVERALL AGREEMENT...AND I HAVE NO MAJOR FAVORITE. GUIDANCE TEMPERATURES CLOSE AND REASONABLE AS WELL...THOUGH THE ULTIMATE FRONTAL POSITIONS OVER THE NEXT FEW DAYS AS WELL AS CLOUD COVER WILL MAKE THE TEMPERATURE FORECAST TRICKY. SHORT TERM...TONIGHT THROUGH MONDAY...SCATTERED CONVECTION WILL CONTINUE TO FIRE ALONG THE FRONT INTO THE EVENING...THOUGH COVERAGE SHOULD DIMINISH WITH THE LOSS OF DIURNAL HEATING. WEAK WAVE LIFTING OUT OF THE SOUTHERN PLAINS AS WELL AS MORE VIGOROUS WAVE PUSHING INTO THE NORTHERN PLAINS WILL BEGIN TO LIFT THE SOUTHERN ILLINOIS FRONT BACK NORTH AS A WARM FRONT TONIGHT INTO SATURDAY. NOT TOO MUCH IN TERMS OF UPPER FORCING EXPECTED OVER FORECAST AREA THROUGH SATURDAY WHICH SHOULD TEND TO KEEP SHOWER/STORM COVERAGE PRETTY SCATTERED. ALSO...THE MODELS ALSO CONTINUE TO BE TOO MOIST IN THE LOW LEVELS AND PRODUCE UNREALISTICALLY HIGH INSTABILITY VALUES. BETTER SHEAR IS FORECAST OVER WISCONSIN AND NORTHERN ILLINOIS ASSOCIATED WITH THE NORTHERN PLAINS WAVE AND WILL COINCIDE WITH THE BEST SEVERE WEATHER THREAT THROUGH SATURDAY. AS THE NORTHERN PLAINS WAVE LIFTS INTO THE GREAT LAKES AND EASTERN CANADA SATURDAY NIGHT INTO SUNDAY...THE TRAILING COLD FRONT WITH THE ASSOCIATED SURFACE LOW WILL PUSH THROUGH THE REGION. THIS FRONTAL APPROACH/PASSAGE WILL ENHANCE THE THREAT OF SHOWER/STORMS ONCE AGAIN ACROSS FORECAST AREA...ESPECIALLY ON SUNDAY. AS HAS BEEN THE CASE LATELY...THIS SECOND FRONT WILL STALL IN THE VICINITY OF THE FORECAST AREA SUNDAY NIGHT AND MONDAY. THIS WILL CONTINUE AT LEAST A LOW CHANCE OF SHOWERS/STORMS THROUGH MEMORIAL DAY. LONG TERM...MONDAY NIGHT THROUGH FRIDAY...MODELS/ENSEMBLES CONTINUE TO SHOW SOME SPREAD...THOUGH THE FLAVOR REMAINS SIMILAR TO YESTERDAY. AFTER A BREAK IN THE PRECIPITATION RISK TUESDAY...THE NEXT WAVE/FRONT IS EXPECTED TO PUSH INTO THE REGION BY MIDWEEK. HAVE CONTINUED WITH THE MAIN CHANCE OF SHOWERS/STORMS ON WEDNESDAY...THOUGH THE MODELS ARE STARTING TO TREND A BIT SLOWER. ONCE THIS SYSTEM PASSES BY TO OUR EAST...COOLER TEMPERATURES ARE EXPECTED TO BUILD IN AS DEEPER TROFFING STARTS TO BECOME ESTABLISHED OVER EASTERN NORTH AMERICA. BAK && .AVIATION... ISSUED 1256 PM CDT FRI MAY 25 2007 CEILING HEIGHTS ARE THE MAIN ISSUE AVIATION-WISE... ESPECIALLY IN THE LONGER TERM. MVFR TO IFR CIGS ARE GENERALLY CONFINED TO A THIN BAND JUST ON THE COOL SIDE OF THE STALLED OUT FRONT... MOST PROBLEMATIC AT KBMI DOWN TO KSPI AT THE MOMENT. KCMI AND KDEC HAVE BEEN...AND LIKELY WILL CONTINUE TO BE TOUCH AND GO WITH THE LOWER CEILINGS THROUGH THE AFTERNOON AS CONVECTION DEVELOPS IN THE WARM SECTOR. VFR CONDITIONS SHOULD PREVAIL AT KPIA THROUGH THE REMAINDER OF THE AFTERNOON. THUNDERSTORMS HOWEVER... WILL REMAIN ON THE WARM SIDE OF THE FRONT... AND DO NOT APPEAR LIKELY TO AFFECT ANY OF OUR TERMINALS. FRONTAL BOUNDARY WILL SLOWLY LIFT NORTHWARD TONIGHT... AND LOW LEVEL JET WILL INCREASE AS WELL... RESULTING IN BROAD AREA OF ISENTROPIC LIFT SUGGESTING SCATTERED SHOWERS CONTINUING ACROSS THE AREA. CEILINGS WILL BE HIGHLY VARIABLE... GENERALLY VFR TO MVFR... BUT LOCALIZED AREAS OF IFR LIKELY... ESPECIALLY NEAR THE BOUNDARY ITSELF. HARDIMAN && .ILX WATCHES/WARNINGS/ADVISORIES... NONE. &&
