Area forecast discussion, May 28, 6:45 PM CDT, 4 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 645 PM CDT TUE MAY 28 2013 .DISCUSSION... ISSUED 300 PM CDT TUE MAY 28 2013 COMPLICATED WEATHER PATTERN IN GENERAL MADE MORE COMPLICATED IN THE MODELS WITH A STRUGGLE WITH THE PATTERN SHIFT OVERALL. HOWEVER...FOR ALL THE NUANCES WITH THE WAVES MOVING THROUGH THE FORECAST AREA...THE ONE AGREED UPON PORTION IN ALL THE OPERATIONAL MODELS IS THAT CENTRAL ILLINOIS WILL BE RATHER WET THROUGH THE END OF THE WEEK. WARM FRONT WELL TO THE NORTH OF THE CWA...LEAVING ILX IN THE WARM SECTOR WITH WARM TEMPS AND DEWPOINTS IN A RATHER MUGGY AIRMASS. THIS WARMTH AND MOISTURE WILL HELP TO FUEL ANY MCS REMNANTS/BOUNDARIES THAT MOVE INTO THE FA...IN ADDITION TO THE OVERALL FRONT SCHEDULED TO MOVE INTO THE MIDWEST AT MIDWEEK. WITH SWRLY FLOW ALOFT...THE FRONT IS GOING TO LOSE ITS FORWARD MOMENTUM...SLOW MOVING...AND SLOW TO EXIT. AS A RESULT...ANY WAVES THAT EJECT OUT OF THE SW AND ALONG THE BOUNDARY WILL RESULT IN ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. HEAVY RAIN IS LIKELY INVOF WHEREVER THE FRONT LANDS...WHICH WILL NOT ONLY BE DIFFICULT TO PIN...FRONT WILL ALSO END UP GETTING INFLUENCED GREATLY BY MESOSCALE INFLUENCES/COLD POOLS/OUTFLOWS AS WELL. WITH GROUND ALREADY VERY SATURATED FROM PREVIOUS RAINS...THE FLASH FLOODING THREAT MAY GET A BREAK TOMORROW FOR PORTIONS OF CENTRAL ILLINOIS...BUT IT WILL BE BACK BY THURSDAY. SHORT TERM...TONIGHT THROUGH TOMORROW... SCATTERED THUNDERSTORMS STILL POSSIBLE THROUGH THE EVENING WITH CONVECTIVE INITIATION LIKELY TO THE WEST IN NRN MO JUST ACROSS THE MISS RIVER VALLEY. BOTH RUC AND NMM/WRF KEEPING SOME ACTIVITY...THOUGH THE RUC/RAP IS ACTUALLY CONFINING MUCH OF THE ACTIVITY TO THE NORTH. THE 4KM WRF/NMM DEVELOPS MORE OF A LINEAR COMPLEX THAT EVENTUALLY MOVES THROUGH THE FA TO THE SE AND WEAKENS AS IT TRAVERSES THE CWA. SHOWER THREAT FINALLY DIMINISHES BRIEFLY FOR WEDNESDAY...THOUGH THE THREAT OF ANY INTERACTION WITH THE WARM FRONT TO THE NORTH RESULTS IN POPS ACROSS THE NRN TIER OF THE STATE. WARM TEMPS...SOUTHERLY WINDS...AND ABUNDANT MOISTURE IN THE BOUNDARY LAYER WILL PUSH HEAT INDEX VALUES INTO THE UPPER 80S/NEAR 90. WINDS WILL BE RATHER BREEZY AND HELP TO COUNTER SOME OF THE EFFECTS...THOUGH CAUTION SHOULD BE USED BY ANYONE OUTDOORS TOMORROW. LONG TERM...THURSDAY THROUGH MONDAY... THE WESTERN TROF DIGS IN...AMPLIFYING THE WAVE PATTERN OVER THE CONUS AND LEAVING THE UPPER MIDWEST IN SWRLY FLOW...THROUGH THURSDAY...WITH WARM TEMPS YET AGAIN ON THURSDAY. TEMPS IN THE NW SHOULD BE SOMEWHAT DAMPENED HOWEVER...BY CLOUD COVER FROM APPROACHING BOUNDARY. IN ADDITION...DIURNAL CURVE WILL LIKELY BE SHATTERED BY THE CONVECTIVE ACTIVITY RUINING THE STEADY CLIMB OF TEMPERATURES IN ANY ONE SPOT AHEAD OF THAT BOUNDARY. FORECAST CONFIDENCE ABOUT DETAILS COMPLICATED WITH THE ELONGATED TROF IN THE ECMWF/NAM IS PROVIDING A SLIGHTLY DIFFERENT SOLUTION WITH THE SFC SYSTEM THAN THE NAM. THAT BEING SAID...THE ECMWF IS LOOKING A BIT MORE LIKE THE GFS IN THE 12Z RUN. THOUGH EVERYONE IS IN AGREEMENT ABOUT ENTERING A PROLONGED PERIOD OF PRECIP THROUGH DAY 5...THE DIFFERENCES IN THE MODELS WILL IMPACT THE DYNAMICS AND ASSOCIATED SEVERE WEATHER THREAT. FORECASTING ONSET OF THE HEAVIEST PRECIP ALONG THE APPROACHING FRONT. IN SUMMARY...THE RAIN IS NOT OVER AS LONG AS THAT FRONT WITH THE NEXT SYSTEM GETS SLOWED BY PARALLEL FLOW ALOFT. HJS && .AVIATION... ISSUED 645 PM CDT TUE MAY 28 2013 PREDOMINANTLY VFR CONDITIONS EXPECTED ACROSS THE CENTRAL ILLINOIS TERMINALS THROUGH THE 00Z TAF VALID TIME. CAN NOT RULE OUT A FEW SHOWERS/STORMS FOR THE EVENING AND EARLY OVERNIGHT HOURS TONIGHT...ALTHOUGH THE GREATEST CONCENTRATION OF PRECIPITATION SHOULD FALL NORTH OF THE TERMINALS CLOSER TO A FRONTAL BOUNDARY TO THE NORTHWEST OF THE AREA. SOUTHERLY WINDS SHOULD PERSIST TO THE SOUTH OF THE BOUNDARY...OUTSIDE OF ANY LOCAL STORM IMPACTS... BECOMING GUSTY DURING PEAK DIURNAL MIXING. BAK && .ILX WATCHES/WARNINGS/ADVISORIES...
