NWS Indianapolis, IN wrote its last area forecast discussion before the first event at May 3, 2:53 PM EST, 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 353 PM EDT MON MAY 3 2010 .SHORT TERM.../TONIGHT THROUGH TUESDAY/. WEAK SURFACE RIDGING ACROSS CENTRAL INDIANA THIS AFTERNOON...WITH PLENTY OF SUNSHINE. SCATTERED CUMULUS HAD DEVELOPED AS THE BOUNDARY LAYER BECAME WELL MIXED. TEMPERATURES HAD WARMED INTO THE 70S AS OF 19Z. FORECAST CHALLENGES FOCUS ON POTENTIAL CONVECTION THIS AFTERNOON AND EVENING AS A MID LEVEL SHORT WAVE AND ASSOCIATED FRONTAL BOUNDARY ARRIVE FROM THE WEST. HAVE TRENDED TOWARDS RUC/NAM/WRF WITH RESPECT TO TIMING OF CONVECTION OVER THE NEXT SEVERAL HOURS. VISIBLE SATELLITE AT 18Z SHOWING AN ENHANCED BAND OF CUMULUS EXTENDING FROM CENTRAL ILLINOIS SOUTHWEST INTO NORTHEAST MISSOURI. CONVECTION HAS QUICKLY DEVELOPED ALONG IT BETWEEN KCMI AND KDEC WITHIN THE LAST HOUR AS CONVECTIVE TEMPERATURES HAVE BEEN REACHED. WILL SEE CONVECTION CONTINUE TO DEVELOP AND EXPAND OVER THE NEXT FEW HOURS INTO WESTERN COUNTIES WITH POTENTIAL FOR STRONG/SEVERE THUNDERSTORMS. CURRENT LAPS SOUNDINGS OVER WESTERN FORECAST AREA ALREADY INDICATING ABOUT 1000 J/KG SBCAPES WITH AN AXIS OF STEEPENING LAPSE RATES AHEAD OF THE MID LEVEL COLD POOL. LOW LEVEL JET WILL STRENGTHEN INTO THE EARLY EVENING AND BRING A THIN AXIS OF DEWPOINTS NEAR 60F INTO THE FORECAST AREA AHEAD OF THE FRONT. GOOD DYNAMICS IN PLAY AS MODEL CONSENSUS FAVORING AN AXIS OF LOW LEVEL CONVERGENCE THROUGH THE EVENING WITH CENTRAL INDIANA LOCATED AT REAR OF UPPER LEVEL JET. COMBINATION OF ALL THESE FACTORS SUGGESTS FURTHER INCREASE IN COVERAGE AND INTENSITY TO DEVELOPING CONVECTION AS IT MOVES INTO THE REGION FROM THE WEST BY LATE AFTERNOON. LARGE HAIL WILL BE THE MAIN CONCERN AS MODEL SOUNDINGS INDICATING PLENTY OF CAPE IN THE HAIL GROWTH ZONE AND WBZEROS OF 8KFT AT A FAVORABLE LEVEL. PRESENCE OF DRY AIR ALOFT WOULD ALSO SUPPORT POTENTIAL FOR LOCALIZED DAMAGING WIND GUSTS. WILL MAINTAIN LIKELY POPS INTO THE EVENING. THUNDERSTORMS SHOULD SHIFT EAST WITH THE BOUNDARY...WITH PRECIPITATION ENDING FROM NW TO SE BETWEEN 01-06Z. SKIES WILL THEN CLEAR PRIOR TO DAYBREAK. HIGH PRESSURE WILL EXPAND INTO THE OHIO VALLEY ON TUESDAY WITH RIDGING ALOFT REESTABLISHING. WITH EXCEPTION OF A FEW LINGERING CUMULUS IN VICINITY OF LOW LEVEL THERMAL TROUGH ACROSS EASTERN COUNTIES DURING THE MORNING...EXPECT ABUNDANT SUNSHINE ON TUESDAY. TEMPS...WENT CLOSE TO MOS GUIDANCE FOR LOWS TONIGHT AS IT SHOULD COOL OFF NICELY BEHIND THE FRONT. WITH SOUTHWEST FLOW ON TUESDAY... WENT A FEW DEGREES WARMER THAN MOS GUIDANCE. && .LONG TERM.../WEDNESDAY THROUGH MONDAY/. TWO SEPARATE SYSTEMS WILL AFFECT CENTRAL INDIANA DURING THE EXTENDED PERIOD. THE CENTER OF THE FIRST LOW WILL PASS OVER THE GREAT LAKES REGION ON WEDNESDAY. THERE WILL BE SOME INSTABILITY DURING THE AFTERNOON HOURS...SO THUNDERSTORMS COULD DEVELOP AS COLD FRONT MOVES THROUGH. WEAK RIDGING WILL DEVELOP OVER THE AREA ON WEDNESDAY NIGHT...BRINGING A BRIEF BREAK IN THE ACTION BEFORE THE NEXT SYSTEM MOVES CLOSER ON THURSDAY MORNING. PREVIOUS MODEL RUNS GFS/GEM/EURO WERE SHOWING SOME DISCREPANCY IN THE TRACK OF THE SECOND LOW...BUT THEY HAVE SINCE COME INTO BETTER AGREEMENT...ALL SHOWING THE BEST DYNAMICS OVER INDIANA. WIND SHEAR SHOULD BE SUBSTANTIAL FOR SOME STRONG THUNDERSTORMS WITH A 100KT UPPER LEVEL JET AND 50KT LOW LEVEL JET. HOWEVER...THE BEST INSTABILITY WILL BE IN THE LATE AFTERNOON ON FRIDAY...AND THE JETS WILL NOT COME THROUGH UNTIL FRIDAY NIGHT. AS FAR AS TEMPS...TRENDED ON THE WARMER SIDE FOR HIGHS THROUGH FRIDAY WITH SOUTHWEST FLOW. HOWEVER...THEY WILL PLUMMET ON SATURDAY IN WAKE OF THE ASSOCIATED COLD FRONT WITH THE SECOND SYSTEM...WENT WITH A BLEND OF MODELS FROM THAT POINT ON. AS FAR AS LOWS THROUGH THE PERIOD...GENERALLY WENT WITH A BLEND OR SLIGHTLY ABOVE ON THE NIGHTS OF INCREASED CLOUD COVER FROM THE LOW PRESSURE SYSTEMS. && .AVIATION...DISCUSSION FOR 03/18Z TAF ISSUANCE. SCATTERED CUMULUS HAS DEVELOPED THIS AFTERNOON AS BOUNDARY LAYER BECOMES WELL MIXED AND UNSTABLE. WELL DEFINED SHORT WAVE WITH ASSOCIATED FRONTAL BOUNDARY MOVING INTO THE MID MISSISSIPPI VALLEY AT THIS TIME. AS THIS SYSTEM PROGRESSES EAST THROUGH THE AFTERNOON...EXPECT SCATTERED THUNDERSTORMS TO DEVELOP WITH AN UNSTABLE ATMOSPHERE ACROSS CENTRAL INDIANA. EXPECT THUNDERSTORMS WILL IMPACT KHUF AND KLAF BY 21Z...AND KIND AND KBMG BY 22Z. STILL SOMEWHAT UNCERTAIN AS TO HOW EXTENSIVE THE THUNDERSTORM COVERAGE WILL BE...SO HAVE MAINTAINED THE VCTS MENTION AT ALL TERMINALS. EXPECT PERIODIC MVFR RESTRICTIONS WITH ANY THUNDERSTORM THAT MOVES ACROSS THE TERMINALS. AS CONVECTION DEVELOPS OVER THE NEXT FEW HOURS...WILL INTRODUCE MORE DETAIL INTO THE FORECAST. WINDS WILL LIKELY BACK TO SW DIRECTION AHEAD OF THE FRONT...SHIFTING TO W/NW IN ITS WAKE. FRONT WILL MOVE ACROSS THE TERMINALS THIS EVENING...WITH SKIES CLEARING QUICKLY BEHIND THE CONVECTION AS DRIER AIR ADVECTS IN. HIGH PRESSURE WILL THEN REESTABLISH FOR THE REMAINDER OF THE FORECAST. MAY SEE SOME BRIEF VISIBILITY RESTRICTIONS PRIOR TO DAYBREAK...AND A FEW LINGERING CUMULUS DURING THE MORNING. OTHERWISE...GENERALLY EXPECTING MOSTLY CLEAR SKIES THROUGH TUESDAY AFTERNOON. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...RYAN LONG TERM....TDUD AVIATION...RYAN
