AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTHERN INDIANA 738 AM EDT TUE JUL 24 2012 .AVIATION... 12Z TAF ISSUANCE...SCATTERED TSRA WILL IMPACT TERMINALS THIS MORNING. STRONGER CONVECTIVE COMPLEX INVOF KORD WILL TRACK SE THIS AM. CONDS SHOULD DETERIORATE TO MVFR WITH THIS MCS...WITH ISOLD BRIEF IFR CONDS POSSIBLE...HOWEVER CONFIDENCE TOO LOW TO INCLUDE IN TAF...SO HELD WITH MVFR. GUST AOA 50 KTS REPORTED WITH UPSTREAMS MCS...HOWEVER REMAINED MORE CONSERVATIVE AS STRONGEST WINDS LOCATED ON SOUTHERN END OF COMPLEX...AND TAF SITES WILL BE IMPACTED BY THE NORTHERN PERIPHERY. SCT SHRA POSSIBLE INVOF TAF SITES LATE AM THRU EARLY AFTN...WITH CONTINUED PRECIP CHANCES INTO EVENING. HOWEVER...UNCERTAINTY WITH EVOLUTION OF PRECIP LEADS TO DRY TAF FCST AFTER 18Z. && .PREV DISCUSSION... /ISSUED 344 AM EDT TUE JUL 24 2012/ SHORT TERM... TUESDAY THROUGH WEDNESDAY NIGHT... SERIES OF CONVECTIVE COMPLEXES DEVELOPING TONIGHT ALONG NORTHERN PERIPHERY OF 500MB RIDGE. LEAD MCS OVER SOUTHERN MN PRIMARY CONCERN FOR POTENTIAL IMPACT IN OUR AREA LATER THIS MORNING. 40KT LLJ COMING UP THROUGH NEBRASKA AND INTO SE SD WILL LEND SUPPORT TO REGENERATIVE NATURE OF CONVECTION...BUT MODELS STILL SUPPORT A FORWARD PROPAGATION OF ONGOING CONVECTION WITH NW/SE ORIENTED THICKNESS PATTERN TAKING IT DOWN TOWARD OUR CWA. MEANWHILE...NEW CONVECTION FIRING OVER SW CWA...INITIAL DEVELOPMENT EXPECTED TO BE OUT OF THE AREA NEAR ISSUANCE BUT WILL NEED TO MONITOR FOR ADDL DEVELOPMENT. OTHERWISE PLAN TO CONTINUE WITH CHANCE POPS TODAY AND SEE HOW MCS HOLDS TOGETHER AS IT TRACKS DOWN TOWARD THE AREA. MODELS THEN SHOWING GOOD AGREEMENT IN LIFTING FRONTAL WAVE TO THE NE OUT OF THE PLAINS...PLACING OUR AREA IN A WELL CAPPED WARM SECTOR FOR MUCH OF WED/WED NIGHT. HAVE TRENDED WX/POP GRIDS ACCORDINGLY AND INTRODUCED PERIOD OF DRY WX FOR SOUTHERN PORTION OF CWA WED AFTN/EVE. EXPECT SIMILAR RESPONSE AS TEMPS DID ON MONDAY WITH SURGING LOW LEVEL THERMAL RIDGE IN WARM SECTOR WILL SEND TEMPS BACK INTO THE MID TO UPPER 90S OVER MUCH OF THE AREA. WITH DEWPOINTS IN THE UPPER 60S TO NEAR 70 WOULD EXPECT HEAT INDICES EXCEEDING 100 FOR SW PORTIONS OF THE CWA AND WILL NEED TO MONITOR FOR POSSIBLE ADV WED AFTN. LONG TERM... THURSDAY THROUGH MONDAY...A SIGNIFICANT SHORTWAVE WILL MOVE SOUTHEAST INTO THE GREAT LAKES REGION LATE THIS WEEK. INITIAL CONCERN FOR THE POTENTIAL FOR SEVERE STORMS GIVEN 345K 850 MB THETA E AND BETTER BULK SHEAR VALUES WITH THIS SYSTEM. ALSO DIURNAL TIMING APPEARS FAVORABLE FOR STORMS CONSIDERING A LATE THURSDAY AFTERNOON FRONTAL PASSAGE. THEREFORE...KEPT THE CHANCE FOR STORMS THURSDAY INTO FRIDAY FOLLOWED BY DRY CONDITIONS THROUGH SUNDAY. STILL SOME POTENTIAL FOR HEAT ADVISORY CONDITIONS THURSDAY OVER SOUTHERN AREAS GIVEN HOT TEMPERATURES AND DEW POINTS IN THE LOWER 70S. CURRENT THINKING IS THE HEAT INDEX OVER AREAS FROM MARION TO PORTLAND SHOULD REACH CLOSE TO 100 DEGREES BY LATE THURSDAY AFTERNOON. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE.
