ANOTHER COLD FRONT WILL MOVE SOUTHEAST ACROSS OUR REGION AROUND SATURDAY BRINGING ANOTHER ROUND OF THUNDERSTORMS AROUND THAT TIME. OTHERWISE...DRY WEATHER WILL BE THE RULE FRIDAY AND AGAIN EARLY NEXT WEEK. TEMPERATURES WILL ALSO REMAIN A LITTLE COOLER THAN NORMAL FOR THIS TIME OF YEAR. && .NEAR TERM /TODAY/... ISSUED AT 353 AM EDT TUE JUL 23 2013 RADAR INDICATES A LINE OF SHOWERS AHEAD OF THE COLD FRONT FROM SOUTH BEND TO NEAR LAFAYETTE TO EAST CENTRAL ILLINOIS. THIS LINE HAS BEEN WEAKENING AND RAPID REFRESH INDICATES THAT IT MAY BRIEFLY DISSIPATE BY MID MORNING. HOWEVER THE COMBINATION OF A COLD FRONT MOVING INTO OUR REGION AND A VERY WARM UNSTABLE AIRMASS WILL CAUSE THUNDERSTORMS TO REDEVELOP BY EARLY AFTERNOON. MODEL CAPES OF UP TO 5000 J/KG ARE INDICATED ACROSS OUR SOUTH THIS AFTERNOON. THIS IS BASED ON SURFACE DEWPOINTS IN THE UPPER 70S WHICH MAY BE A LITTLE BIT HIGH. NERVELESS A VERY UNSTABLE AIRMASS WILL BE ACROSS OUR REGION...ESPECIALLY SOUTH. SPC HAS OUR SOUTHWEST IN A SLIGHT RISK OF SEVERE THUNDERSTORMS. WILL RAISE A POPS A LITTLE MOST AREAS...ESPECIALLY SOUTH THIS AFTERNOON. HIGHS TEMPERATURES TODAY WILL RANGE FROM THE LOWER 80S NORTH TO NEAR 90 SOUTH. WENT SLIGHTLY ABOVE A MOS BLEND IN THE NORTH... OTHERWISE NO SIGNIFICANT CHANGES MADE. && .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... ISSUED AT 353 AM EDT TUE JUL 23 2013 A FEW THUNDERSTORMS MAY LINGER IN OUR FAR SOUTH THIS EVENING. OTHERWISE...DRY AND COOLER WEATHER WILL BE THE RULE THROUGH THURSDAY NIGHT AS HIGH PRESSURE OVER THE UPPER MIDWEST BUILDS SOUTHEAST ACROSS OUR REGION. THE NAM INDICATES 850 MB TEMPERATURES AS LOW AS +7 DEGREES WEDNESDAY WHILE THE GFS IS CLOSER TO +10. ON WEDNESDAY AFTERNOON THE NAM HAS TWO METER TEMPERATURES IN THE LOWER 70S WITH MID 70S SOUTH.

A MOS BLEND ON TEMPERATURES SEEM REASONABLE MOST AREAS...ALTHOUGH I TWEAKED THEM UP A DEGREE OR TWO IN SOME AREAS. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...

ISSUED AT 1158 AM EDT TUE JUL 23 2013 A COLD FRONT HAS NOT YET REACHED CENTRAL INDIANA AT THIS HOUR BUT SHOULD EVENTUALLY MOVE VERY QUICKLY THROUGH THE HOURS OF 19-00Z. THERE HAS BEEN VERY LITTLE DEVELOPMENT UPSTREAM...AND THE BULK OF THE GUIDANCE HAS NOT HANDLED THIS FEATURE VERY WELL...SAVE FOR THE HRRR WHICH IS BASICALLY KEEPING MOST OF CENTRAL INDIANA DRY FOR THE FRONTAL PASSAGE. IT DEPICTS A WEAK LINE FORMING AROUND 20Z...AND THEN QUICKLY DISSIPATING. SO THERE IS VERY LITTLE CONFIDENCE IN POPS AT THIS TIME AND WILL CONTINUE TO OMIT ANY MENTION OF SHOWERS OF TS FOR NOW. IF DEVELOPMENT OCCURS LATER IN THE AFTERNOON THEN THIS CAN BE TIMED IN THE TAFS. SUSTAINED WIND SPEEDS WILL RANGE BETWEEN 6 TO 12 KTS WITH SOME GUSTS UP TO 20 KTS THIS AFTERNOON AND EVENING. POST FRONT...WINDS WILL BECOME NORTHERLY THIS EVENING AT 5 TO 10 KTS. && .IND WATCHES/WARNINGS/ADVISORIES...
