Well, we had some morning fog to contend with but once it burned off we were rewarded with plenty of warmth & sunshine for the afternoon. As of 5PM, the high temperature was 88° with heat indices in the 90s. Dew Points still pretty high in the low 70s so it did make it feel pretty sticky today. Its not that your body sweats more but its the fact that humdity in the atmosphere isn't all that conducive to evaporation. Evaporation is your bodys way of cooling you off. We'll probably stay humid for the next few days but there is a cold front headed our way. This will usher in a cooler brand of air. We could go 3-4 consecutive days below 80. For some away from the city weekend temps could fail to reach 70s Saturday, particularly North. As I've stated in previous blogs in each September over the past 10 years Indianapolis has recorded a high temperature in the 60s. Also, in 8 of those, we've recorded a 40° low temperature. There were no 40s in 2008 and 2009.

With the much needed weekend rainfall, we continue to see even more of a dent in the deficit. Not only are our numbers getting closer to where they should be for the year but also reservoir levels are on the rise. This is bringing up stir for debate on whether watering restrictions/bans should be lifted and it will be lifted tomorrow afternoon.
"I am pleased to lift the water ban with the strong word of caution that residents continue to be judicious in their water use," said Mayor Ballard. "Despite recent heavy rains, it falls upon everyone to work together and follow Citizens' voluntary conservation recommendations to keep demand low."We do pretty much have daily chances for rain over the next 5 days but not all are complete washouts & some may not see a drop but for others, their could be quite a big gusher. Saturday looks to be the wettest day.

If you do the math (well...I've done it for you) than you can see we've picked up 12.05" since May 1st, 9.35" since June 1st, 8.52" since July 1st, 8.43" since August 1st, and 1.92" since September 1st. Now 24 out of the past 127 days have been recorded with measurable rainfall. Measurable Rainfall is anything 0.01" or higher (Trace Amounts aren't measurable).
We should stay dry tonight and all day tomorrow but tomorrow evening there is the threat for severe weather. SPC has put Indiana in a slight risk for severe thunderstorms Wednesday. This really goes for NW Indiana & Upper Great Lakes Region which includes Chicago along with most of Illinois. This could possibly hangout into the Thursday Morning. We should dry out & see more sunshine (Thursday Afternoon) before more weekend chances for rain arrives along with cooler temperatures.
10 Day Total Precipitation Numbers are over 3 inches!! I think this are coming off pretty heavy. I expect this number to come down but I think we should only squeeze out maybe an inch. Most of these rain chances are weak. I think Saturday is our best shot at rain along with some on Wednesday Night.
METEOROLOGICAL SUMMER (JUNE-JULY-AUGUST)
Meteorological summer has ended and it went down as the 5th warmest summer on record. It started off hot & dry. We had a avg temp of 74.6° for the month of June and only 0.09" of rain. The avg temp of July was 84° with 0.83" of rain. The warmest high temperature in June was 104° on June 28th and the coolest low was 48° on June 2nd (the last day the city saw 40s).
The warmest high temperature in July was 105° on both July 6th and 7th (1° away from the tying the record for all time highest temperature in Indy, 106°). The coolest low temperature was 61° on July 21st.
Then August rolled around and the tables turned. We recorded 13 consecutive days with an avg daily temp at or below normal (84°), which started August 9th and ended on the 13th. August finished with a avg temp of 74.9°. The warmest high temperature for August was 98° on August 8th. The coolest low temperature was 54° on Aug. 18th.
The August cool off had dropped Summer 2012 from being the #1 warmest on record to the 5th warmest on record.
Out of the seasons 92 days; 69 days were above normal (75%), 4 days were normal(4.3%), and the remaining 19 days were below normal(20.7%). The average high for this season is 89.4° with an avg low of 66.2°. This put the avg summer temperature at 77.8° which is about 5° above normal. 19 out of the past 21 months have been above normal (since Dec 2010). Top Five Warmest Summers:
2) 1936---78.5°
3) 1934---78.2°
4) 2010---78.1°
5) 2012---77.8°
Currently, we sit at 51 days with temps 90+ for the year. We need 7 more to tie the record of 58 set in 1983 and 8 more days to break it. At this point it doesn't look like we will reach this historic record.
I've taken a look back 5 years and in September we've had no more than 5 days with temps 90+. We had 5 in 2007 and 2010. 4 last year and 3 in 2008. There was none in 2009.
SEPTEMBER
2011: 99° on 1st & 2nd. 100° on 3rd. 92° on 13th.
2010: 91° on 1st & 13th, 90° on 6th, 96° on 21st, 94° on 23rd.
2008: 91° on 1st 7 3rd. 93° on 2nd.
2007: 91° on 3rd, 94° on 2nd, 96° on 3rd, 90° on 23rd, & 92° on 24th.
This pretty much averages out to 2-3 days. Also, while I'm talking about record heat, the record for most 100° days in a year is 12 set back in 1936. We stand at 9 this year. That will likely stand tall. This is Record Position #3.
