Area forecast discussion, Jun 4, 7:45 PM EDT, 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 745 PM EDT FRI JUN 4 2010 .AVIATION... DIFFICULT AVIATION FORECAST WITH RESPECT TO CONVECTIVE CHANCES AT TAF SITES THIS PERIOD. SHORT WAVE PASSING THROUGH THE GREAT LAKES GENERATING SCATTERED CONVECTION ALL AROUND THE AREA BUT NO IMMEDIATE IMPACTS AT TAF LOCATIONS. KFWA LOOKS TO HAVE BEST CHANCE AT TSRA LATER THIS EVENING BUT EVEN THAT MAY BE A GLANCING BLOW AS RADAR SHOWS CONVECTION IN NORTHWEST INDIANA SLIDING SOUTHEAST AT CURRENT TIME. INCLUDED A TEMPO GROUP FOR THIS PASSAGE. MODELS RATHER AGGRESSIVE WITH DEVELOPING A STRONG MESOSCALE CONVECTIVE COMPLEX UPSTREAM TONIGHT AND RIDING IT EAST INTO OUR AREA SATURDAY. PROBLEM LIES WITH RATHER POOR HANDLING OF CURRENT CONVECTION TO OUR SOUTHWEST WHICH APPEARS FURTHER SOUTH THAN MODEL FORECASTS. WILL KEEP A CB MENTION AT KSBN TOMMORROW AND A VCTS AT KFWA BUT CONFIDENCE LOW UNTIL WE SEE HOW THINGS DEVELOP UPSTREAM OVERNIGHT. COULD CERTAINLY BE A PROLONGED WINDOW OF MODERATE TO HEAVY RAIN WITH TSRA AND MVFR TO IFR CIGS WITH THIS CONVECTIVE COMPLEX BUT LOCATION REMAINS TOO UNCERTAIN FOR GREATER WX IN TAFS AT THIS TIME. && .SHORT TERM... TONIGHT THROUGH SATURDAY NIGHT... SFC FRONTAL BOUNDARY WITH MULTIPLE WAVES TO IMPACT THE AREA IN THE SHORT TERM. FIRST ROUND ALREADY INITIATING IN EXTREME SE CWA AS BOUNDARY LAYER QUICKLY DESTABILIZING. VIS SAT DEPICTING CONVERGENT BOUNDARY WITH ENHANCED CU FIELD FROM FDY TO AOH TO MIE. MID LEVEL SUPPORT MAKING ITS WAY ACROSS CENTRAL GREAT LAKES AS WELL WITH KGRR VWP INDICATING MODEST 50KT SPEED MAX AT 500MB. NORTHWARD PUSH OF SFC FRONTAL BOUNDARY EXPECTED TO CARRY THIS FEATURE JUST NORTH OF THE CWA RESULTING IN INC LOW LEVEL MOISTURE AND CONTINUED DESTABILIZATION...BUT ALSO LEAVING LIMITED FORCING AND FOCUS FOR CONVECTION THIS EVENING. AS A RESULT...PLAN TO LEAVE POPS IN CHANCE RANGE FOR TONIGHT AS FOCUS THEN SHIFTS TOWARD ARRIVAL OF NEXT WAVE RIDING ALONG THE BOUNDARY SATURDAY MORNING. LOW LEVEL FORCING TO ORGANIZE BACK IN CENTRAL PLAINS OVERNIGHT IN SUPPORT OF NOCTURNAL MCS DEVELOPMENT AS STRONG MOISTURE TRANSPORT AIDED BY 50+KT LLJ NOSES INTO SOUTHERN IA OVERNIGHT. EVOLUTION OF THIS FEATURE TO GO A LONG WAY IN DETERMINING OUTCOME OF SENSIBLE WEATHER FOR OUR AREA ON SATURDAY. MODEL INDICATIONS ATTM POINT TOWARD AN EASTWARD PROPAGATING MCS AS IT RIDES ALONG 850-300MB THICKNESS RIDGE INTO OUR WESTERN CWA. WILL REWORK MORNING WX GRIDS ACCORDINGLY TO ACCOUNT FOR THIS...BUMPING UP TO LIKELY IN WESTERN HALF. LOW LEVEL FORCING TO MAINTAIN INTO SATURDAY AS LLJ PUSHES INTO NORTHERN ILLINOIS BY 18Z. THIS WILL BE ACCOMPANIED BY SFC FRONTAL WAVE AND LENDS SUPPORT TO A REGENERATIVE MCS TYPE PATTERN. COMBINE THIS WITH PW PROGGED TO BE IN THE 1.5-2.0 INCH RANGE AND POTENTIAL FOR HEAVY RAIN CERTAINLY IN PLAY SATURDAY AFTN/EVENING. TEMPS THROUGH THE PERIOD APPEAR ON TRACK AND ONLY MINOR ADJUSTMENTS MADE. && .LONG TERM.../SUNDAY THROUGH THURSDAY/... ON SUNDAY SFC LOW WILL BE MOVING AWAY TO THE EAST YET STILL PULLING COLD FRONT/INVERTED TROUGH BEHIND INTO THE AREA EARLY. 12Z NAM/9Z SREF FASTEST CLEARING THE CWA WITH 12Z GFS/ECMWF SLOWER AND MAINTAINING SHRA IN THE EAST EARLY. WITH MIXED GUIDANCE WILL RETAIN EARLY SUNDAY CHC POP FOR EASTERN AREAS AFTER WHICH COOLER DRIER AIR OVERSPREADS THE REGION AS ZONAL FLOW ALOFT BUCKLES SOMEWHAT INTO MILD TROUGHING OVER THE GREAT LAKES. NAM12/GFS ALSO TRY TO FIRE SOME LIGHT SHRA AS WEAK MID LEVEL SHRTWV DROPS THROUGH NW FLOW BUT GIVEN DRY AIR PERMEATING LOWER LEVELS WILL CONTINUE TO RIDE DRY GRID AT THIS TIME. QUIETER PERIOD THEN APPEARS IN STORE THOUGH SIGNIFICANT MODEL DIFFERENCES ARE BEGINNING TO APPEAR. OP GFS HOLDS ON TO STRONGER RIDGING OVER THE PLAINS KEEPING A STEEPER AND COOLER NW FLOW ALOFT OVER THE REGION...WHILE THE ECMWF REMAINS MORE ZONAL FLOW. BOTH DEVELOP MCS ACTIVITY UPSTREAM TUESDAY AND BRING IT EASTWARD...BUT THE MORE AMPLIFIED GFS ROLLS THIS ACTIVITY SOUTH OF THE CWA. AGAIN CHC POPS ARE REASONABLE THOUGH IF CURRENT GFS/GFS ENSEMBLE MEAN TIMING REMAINS CONSISTENT A FORWARD ADJUSTMENT IN TIME COULD BE NEEDED.. LATE PERIOD GFS THEN PROGRESSES ITS EARLIER AMPLIFICATION DOWNSTREAM WHILE THE ECMWF INTENSIFIES RIDGE CENTERED ALONG GULF COAST. IN BOTH CASES THIS FORESHADOWS A WARMING TREND THOUGH WITH THE MED RANGE MODELS DIFFERING IN THE MECHANISM WILL REMAIN CONSERVATIVE WITH LATE PD TEMPS INCREASING INTO THE LOW 80S&& .AVIATION... AREA OF SHOWERS AND THUNDERSTORMS OVER IA/WI MOVG EAST INTO DRIER AIR AND WKNG. SOME POSSIBILITY THAT TSTMS WILL DVLP ALONG OUTFLOW BOUNDARY WELL AHEAD OF MN/IA CDFNT AND AFFECT NRN INDIANA THIS AFTN AS FCST BY 00Z 4KM NMM-WRF, BUT GIVEN LACK OF EVIDENCE OF THIS FEATURE ATTM AND QUESTION IF MOISTURE/INSTABILITY WILL RETURN TO OUR AREA QUICKLY ENOUGH FOR CONVECTION TO DEVELOP THIS AFTN EVEN IF OUTFLOW BOUNDARY DOES MATERIALIZE, BELIEVE BETTER CHC LIES CLOSER TO FRONT MOVG INTO THE AREA TONIGHT... THUS PUSHED BACK TEMPO TSRA GROUP WITH MVFR CONDITIONS 4HRS AT BOTH TERMINALS. OTRWS, VFR CONDITIONS SHOULD PREVAIL THROUGH THE PERIOD. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE.
