NWS Indianapolis, IN wrote its last area forecast discussion before the first event at Aug 9, 12:40 PM EST, 2 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 140 PM EDT THU AUG 9 2007 DISCUSSION... TONIGHT...MAIN ISSUE TONIGHT WILL BE ONGOING TSRA AND THEN OVERNIGHT LOWS. SURFACE BOUNDARY WAS CLEAR ON VIS SAT AND IN SURFACE OBSERVATIONS. MOS POPS ARE VERY LOW FOR TONIGHT BUT WILL GO WITH SCATTERED TSRA ALONG AND SOUTH OF THE AFOREMENTIONED SURFACE BOUNDARY WHICH AT 18Z WAS ROUGHLY FROM FWA TO HUF. THE ACTUAL COLD FRONT WAS BACK OVER CENTRAL IOWA AND WAS EVIDENT IN AFTERNOON TEMPERATURES AND CU FIELD. 12Z MOS OVERNIGHT LOWS SEEM A BIT COOL. LOOKING UPSTREAM YOU HAVE TO GO UP INTO SOUTHERN MN TO SEE DEWPOINTS IN THE UPPER 60S. THIS MAY TAKE UNTIL NEAR OR JUST AFTER SUNRISE TO GET HERE SO WILL RAISE MOS LOWS A FEW DEGREES. && .EXTENDED DISCUSSION...FRIDAY AFTERNOON THROUGH THURSDAY FOR FRIDAY AFTERNOON THE MAIN POINT OF INTEREST WILL BE IF TEMPERATURES DROP BELOW 90 AT INDIANAPOLIS. HIGH PRESSURE WILL BUILD INTO INDIANA. LOOKING AT THE PREVIOUS RUNS THE GFS TAKES A JUMP IN THE TEMPERATURE TOMORROW AFTER BEING CONSISTANT THE PREVIOUS 2 RUNS. IT IS ALSO THE WARMEST. THE ETA AND NGM HAVE BEEN MORE CONSISTANT. ALL THE MODEL SOUNDINGS SHOW A WEDGE OF HIGH RH AROUND 800 MB. SO WILL GO TOWARD THE MIDDLE OF THE FCST WITH HIGH FROM UPPER 80S NORTH TO LOWER 90S SOUTH. DEW POINTS WILL DROP OFF INTO THE UPPER 60S SO IT WILL BE MORE COMFORTABLE. WITH THESE CONDITIONS A HEAT ADVISORY WILL NOT BE REQUIRED. ON SATURDAY AND MOST OF SUNDAY THE HIGH PRESSURE WILL BE THE DOMINATING FACTOR. MODELS DO SHOW A WARMING TREND AT 850 MB. THE GREATEST IS THE GFS WITH AN INCREASE OF 3C FROM FRIDAY. THE NAM DOES SHOW SOME WARMING BUT NOT AS GREAT. THERE WILL BE MUCH LOWER HIGH LEVEL MOISTURE WHICH WILL GIVE MORE SUNSHINE. THIS WILL HELP WITH INCREASING TEMPERATURES. WILL GO WITH TEMPS A FEW DEGREES WARMER THEN FRIDAY. THE HIGH PRESSURE WILL SLIP TO THE EAST ON SUNDAY. WITH THE FLOW SHIFTING TO THE SW TEMPERATURES WILL CONTINUE TO INCREASE SOME. HIGHS WILL TOP OUT IN THE LOWER TO MIDDLE 90S. THE NEXT WEATHER FACTOR WILL BE THE EFFECT A FRONT MOVING IN FROM THE N WILL HAVE ON INDIANAS WEATHER. THIS SYSTEM IS MUCH LIKE THE ONE THAT HAS BEEN OVER INDIANA THE PAST WEEK. THE FRONT WILL BECOME STATIONARY OVER NORTHERN INDIANA. WITH THE UPPER LEVEL MOISTURE BEING LIMITED THE FRONT WILL GIVE ENOUGH INSTABILITY TO CAUSE ISOLATED MAINLY AFTERNOON THUNDERSTORMS MONDAY THROUGH WEDNESDAY. ON THURSDAY THE FRONT WILL MOVE TO THE NORTH. WITH HIGH PRESSURE THEN MOVING IN THIS WILL GIVE A DRY END OF THE WEEK. HIGH TEMPERATURES WILL REMAIN IN THE 90S. && .IND WATCHES/WARNINGS/ADVISORIES...
