Spring 2012(MAR-APR-MAY)
Its been a long warm spring! Going back to March we began the first 10 days on topsy turvey. Strong thunderstorms moved across the state that spawned deadly tornadoes killing dozens of residents as it moved along the Ohio Valley on March 2nd. Then, chilly air settled for the weekend which managed to pop out some snow showers from the sky adding to 0.7" for March 4th & 5th combined, which was the last snowfall recorded. Afterwards, a shift to a strong southerly wind flow on the 6th caused a chilly morning low of 29° to skyrocket to a afternoon high of 69°. The mild air was only briefly interrupted March 9th but from there a string of above normal days begin, reaching our first 70° day on the 12th and 1st 80° on the 14th. This stretch of mild air remained locked in dominating the remainder of the month stirring numerous record events and challenging others.
The streak ended once April came to the front door. Although, there was a warm 84° record high temperature reading for April 3rd, half the months days were below normal. In fact, the thermometer dipped below freezing to 29° the morning of April 11th. This was our last freeze date for the season and year thus far. Prior to this date, you will have to go back about 32 days to March 10th since our last freeze. April ended with a rare occurence in Indiana Weather History since 1872. April 2012 became the 2nd April to finish -3° cooler than March. The previous occurence was 1907.
This brings us to the month of May. After a cool April, temperatures rebounded. As of May 30th, only 2 days below 70° for the month, those occured back-to-back the 9th and 10th. Otherwise all kinds of 70s and 80s on the calendar, including the first three (consecutive) 90s (for May 26th-28th). This puts the avg high temperature at 80° for the month with an avg temp of 70°, running 7° above normal. This will go down as the warmest spring on record.
Past Weekend
A summer heat wave in Spring wih temps running 15° above the normal high of 76°. We recorded 87° for Friday, 90° for Saturday, 91° Sunday, and a high of 90° Monday. These temps are more typical for Tampa Bay, Florida at the end of May. No daily record highs were set over the weekend. High humidity resulted in low pollen count as well so that was one plus side to go along with plentiful sunshine to make the weekend semi-decent.
Tues-Fri
Most returned for Back to Work Tuesday and relief from the heat now taking center stage.
Thundershowers swept through Indianapolis Tuesday Morning dropping some much needed rainfall not just for the city but for the state. Even though we did pick up 0.36" here, most of the state is in a rain deficit. Here in Indianapolis, we are 2.49" below normal for May, 2.36" below normal for the season, and 2.57" below normal for the year. Bloomington has it the worst in the state. They average 5.87" for May, 13.86" for Spring, and 19.8" for the 1st five months of the year. So far they have picked up 2.11" for May, 8.02" for Spring, and 13.86" so far this year. This puts them at 3.76" below normal for the month, 5.84" below normal for the season, and 8.17" below normal for the year. Terre Haute also fits into this category as well. These numbers will get smaller over the next few days but not too impressive. We have A LOT of rain to catch up on around the state.
We're tapping into some cooler air where temps will fall below normal over the next few days. To go with it, we are expecting some rain Thursday Afternoon into Friday Morning. During this time, Thursday Afternoon Highs will struggle to top 70s as we lose the chance for daytime heating. The rain looks to arrive around the noon hour into Western Indiana and by 2pm in the Circle City, this will keep us cool. We are expecting mostly heavy rain in Central Indiana but cannot rule out a few rumbles of thunder and a few flashes of lightning. Not expecting any severe weather out of this here. Looking at totals of up to an inch around the state with localized heavier amounts by Friday Afternoon. Temps fall to low to mid 50s tonight with highs in the upper 60s Thursday. Also expecting 60s for Friday and Saturday as well.

As the cooler weather pattern continues we can expect temps to fall into the upper 40s for Saturday Morning Lows with Highs reaching the upper 60s to possibly low 70s. Our next rain chance slides in late Saturday Afternoon into Saturday Night. This system looks weak. It actually appears we may dry out again but stick with more seasonal temps for next week ranging from mid 70s to low 80s. Is this just a brief interruption from the heat or is this a short sample as to what could come this summer? Long Range Forecasts were showing slightly below normal to near normal temperatures with equal chances for below, above, or near normal precipitation a few months ago. Will monitor the latest in summer outlooks and update on a consistent basis but looking ahead the next 2 weeks and temps looks to read near normal with below normal precipitation.
