.DISCUSSION...

...HEAT ADVISORY FOR SOUTHWEST COUNTIES TUESDAY...

RADAR MOSAIC SHOWS AREAS OF THUNDERSTORMS STRETCHING FROM C WI INTO
W OH. VIS SAT LOOP SHOWS A LOT OF BLOWOFF AND CONVECTIVE DEBRIS OVR
CENTRAL INDIANA WITH SOME CU MANAGING TO FORM UNDERNEATH IT. TEMPS
ARE IN THE UPR 70S TO UPR 80S WITH DEWPTS IN THE MID 60S TO LOW 70S
AND LIGHT SLY WINDS.

FCST FOCUS IS ON POPS/TEMPS/DEWPTS NEXT DAY OR TWO. MODELS IN GOOD
AGREEMENT ON OVRALL PATRN SO WL USE A BLEND.

TONIGHT...MODELS SUGGESTING POSSIBLE MCS OVRNIGHT MVING FROM IA/IL
INTO INDIANA. WAA WILL BE SIGNIFICANT WITH STRONG LL JET. THIS SHUD
PROVIDE SOME GOOD ISENTROPIC FORCING AS WELL OVR IL. PLENTY OF
MOISTURE STARTING TO MV IN. GUIDANCE WAS UP IN THE
LIKELY/CATEGORICAL AREA AND GIVEN MODELS HANDLING OF MCS AM NOT
CONFIDENT ENUF OF PLACEMENT TO GO THAT HIGH. WL STICK WITH CHC NE TO
DRY SW. FOR LOWS WL BUMP WARMEST GUIDANCE UP A DEGREE OR TWO.

TUE...SHUD SEE HIGH TEMPS CLIMB INTO THE 90S FOR AT LEAST THE SW
HALF OF THE AREA WITH WAA AND STARTING FROM LOWS IN THE MID 70S. TO
THE NE COULD SEE DEBRIS CLOUDS KEEP THE TEMPS FROM CLIMBING AS MUCH.
DEWPTS REACHING INTO THE LOW TO MID 70S SIMILAR TO THOSE IN IL TODAY
WILL YIELD APPARENT TEMPS AROUND 100 IN SWRN COUNTIES SO WL ISSUE
HEAT ADVISORY FOR THAT AREA FOR THE AFTERNOON. STILL IN A SLT RISK
OF SVR WEATHER AS FNT MVS THRU TOMORROW WITH BIG INSTABILITY AND
DECENT SHEAR AS WELL AS PERHAPS SOME LEFTOVER CONVECTIVE BOUNDARIES.
WITH THIS IN MIND HAVE KEPT CHC THUNDER OVR THE ENTIRE AREA AS FNT
MVS THRU.

TUE NT...CONT WITH CHC POPS AS FNT SINKS TO THE S. WITH CLDS AROUND
AND H8 TEMPS JUST STARTING TO DROP WL KEEP LOWS IN UPR 60S TO LOW
70S CONSISTENT WITH A GUIDANCE BLEND.

WED...FNT SLOWS NR THE OH RVR AS A WAVE MVS ALONG IT SO HAVE KEPT A
CHC IN THE SRN COUNTIES. A BIT OF CAA STARTS UP BEHIND THE FNT BUT
HTS DON/T FALL MUCH SO WL STICK WITH HIGHS IN THE MIDDLE TO UPR 80S.

WED NT...HTS FALL MORE AS UPR TROF STARTS TO DIG INTO THE AREA. NO
FORCING LEFT SO HAVE KEPT POPS DRY. USED A GUIDANCE BLEND IN THE LOW
TO MIDDLE 60S.

EXTENDED...UPR TROF JUST TO THE E PUTS FA IN NW FLOW PATRN WITH
LOWER HTS...THICKNESSES...AND H8 TEMPS THAN NORMAL FOR THIS TIME OF
YR. EXTENDED MODELS AND ENSEMBLES ARE IN GOOD AGREEMENT ON THIS
OVERALL MERIDIONAL UPR PATRN SO HAVE GOOD CONFIDENCE IN HPC FCST
BLEND. HIGHS IN THE LOW TO MID 80S AND LOWS IN THE UPR 50S TO MID
60S. ONLY ISOLATED CHCS FOR PRECIP WITH IMPULSES TRAVELING THRU THE
UPR TROF PERIODICALLY AND A BIT OF INSTABILITY FROM COOLER MID LVL
TEMPS. GIVEN THE VERY ISOLATED NATURE OF THIS POSSIBILITY WL
CONTINUE WITH DRY FCST FOR FA DURING THIS TIME. EXPECT SKIES TO BE
PARTLY TO MOSTLY CLOUDY DURING THE DAY AND PARTLY CLOUDY AT NIGHT.
