NWS Chicago, IL wrote its last area forecast discussion before the first event at May 30, 6:45 PM EST, 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 645 PM CDT TUE MAY 30 2006 .DISCUSSION FOR AFTERNOON ZONES/GRIDS... 215 PM CDT THE MOIST...UNSTABLE AIRMASS REMAINS IN PLACE OVER THE REGION. EXPECTING MORE SHRA/TSRA TO DVLP OVER THE REGION THIS AFTERNOON AND EVENING. BUT INITIALLY...THE ACTIVE CONVECTION IS CONFINED TO SRN WISCONSIN...INVOF A WEAK COLD FRONT EXTENDING FROM SRN WISCONSIN SWWD INTO CENTRAL KANSAS. A LOW LEVEL CONVERGENCE BOUNDARY HAS SET UP ACROSS THE CWA...EXTENDING FROM THE CONVECTIVE CLUSTER IN SERN WISCONSIN...THROUGH THE CWA INTO ERN LIVINGSTON COUNTY. THIS BOUNDARY WILL BE MONITORED CLOSELY. WHILE MANY INDICATORS ARE POINTING TO AN ACTIVE EVENING ACROSS THE CWA...BUT THE ONE INGREDIENT THAT APPEARS TO BE LACKING A BIT IS THE UPPER FORCING. THE INITIAL OBSERVED SITUATION WOULD POINT TOWARD A MODEL GUIDANCE SOLUTION CLOSER TO THE GFS THAN THE NAM/ETA. THE GFS IS A BIT WEAKER AND FURTHER NORTH WITH THE INITIAL SHORT WAVE TROUGH...OVER SRN WISCONSIN. HOWEVER...DUE TO THE HEAT/HUMIDITY AND STEEP LOW LEVEL LAPSE RATES...DO NOT WANT TO MINIMIZE THE CHANCES OF SHRA/TSRA...IN FACT...PREFER THE IDEA OF INCRG POPS TO FROM LIKELY TO CATEGORICAL...EVEN IF STRENGTH OF CNVTV ACTIVITY IS NOT QUITE UP TO LEVEL OF YESTERDAY. THROUGH THE REMAINDER OF THE SHORT TERM FORECAST...THE DIFFERENCES BETWEEN THE THE GFS AND THE NAM/ETA REMAIN MAINLY IN THE AREA OF THE TIMING OF INDIVIDUAL SHORT WAVES THROUGH THE SYNOPTIC SCALE FLOW PATTERN. THE GUIDANCE IS LEANING TOWARD A BUILDING RIDGE OVER THE SRN APPALACHIANS AND THE NRN ROCKIES WITH A BROAD TROUGH FORMING OVER THE NRN PLAINS AND GREAT LAKES...FROM A DVLPG POLAR VORTEX OVER NERN CANADA. THE DVLPG UPPER TROUGH WILL FORCE THE WEAK COLD FRONT TO PUSH THROUGH THE UPPER MIDWEST...AND ALLOWING SOME MODERATION TO TEMPERATURES. TEMPERATURES SHOULD RETURN CLOSER TO CLIMATOLOGICAL NORMAL LEVELS...WITH HIGHS IN THE UPPER 70S TO AROUND 80 FOR THE REMAINDER OF THE WORKWEEK. THE ONLY CHANGE MADE TO THE LONGER RANGE FORECAST WAS TO INTRODUCE A CHANCE OF SHRA/TSRA ON SUNDAY...AS THE GFS BRINGS ANOTHER SHORTWAVE AROUND THE WESTERN PERIPHERY OF AN UPPER LOW EXPECTED TO DVLP OVER NEW ENGLAND. KREIN && .AVIATION... FOR 00Z TAFS...DIURNAL PUNCH HAS SHOWN TRUE TO FORM THIS AFTN. SHUD BE A NOISY EVENING...ALTHO SEVERITY IS LESS POTENT. APPEARS SFC LOW HAS MOVED INTO NRN IL TAKING COLD FRONT INTO NRN IL PAST ORD AND RFD. MODELS NOT PICKING UP ON THIS MOVEMENT THAT FAST. LOW SHUD MOVE NEWD ALONG THIS BOUNDARY...SWITCHING WINDS TO NORTH IN REMAINING TERMINALS PRE-DAWN OR EARLY WED MRNG. POST FRONTAL PUSH SHUD SUCK DOWN COOLER FLOW AND LOWER CONDENSATION LEVELS SO THAT CIGS SHUD BE DROPPING BLO 3K SEVERAL HOURS AFTER STRONG NORTH PUSH. TIMING IS SUSPECT ON THIS...BUT MODELS BRING IT DOWN ON WEDNESDAY. LIKELY TO BE SOME SHOWERS WITH THIS IN THE MRNG BUT HAVE LEFT TAFS DRY FOR NOW WITH MAIN CONCENTRATION ON THIS EVENINGS SCENARIO.
