Mean temperature for June-July-August was the warmest since 1995 (even beating 2012) due to consistent warmth since late May & a lack of many days at or below normal.
The daily highs averaged out to the highest since 2012, while the overnight lows were the warmest since 2011.
At the Purdue Airport, the rainfall of 7.75" for the summer was 4.08" below normal.
At our WLFI ob site, the Summer 2020 rainfall total was just 6.69".
The hottest summer on record was in 1936. The average temperature in a summer occurred in 1934, while the driest summer on record was in 1933.
Records go back to 1879 at Purdue (Purdue University 1879-1954.....Purdue University Airport 1954-present).
I will have more on this in the coming week or two as new data comes out & maps are made to show how the rest of the viewing area faired.
Other than a couple of isolated showers in the southeast Wednesday, it looks like a dry day with clouds/sun, a southwest wind at 7-15 mph & highs 82-87 with pretty high humidity (dew points 60s to 70). This, after any lingering showers tonight depart & we see some patchy fog (with lows 65-70).
Most of the showers & storms will stay south of our area Wednesday.
Thursday looks like a partly cloudy, windy day with southwest to west-southwest winds at 15-32 mph as cold front approaches after some early morning patchy fog & lows 62-66.
Highs of 84-89 are likely with dew points of 66-71 leading to heat indices of 86-93.
I put 30% pops for storms in the evening with potential of a narrow, broken line developing. Models don't do much with this front, however, other than pops a few brief showers.
Most of the storms & severe weather risk will be in the mid-Ohio Valley & Mid-Atlantic region on Thursday to Thursday night.
Here, we look quite capped about about 7000' preventing much development, but I like 30% POPs to account for any cap breakage.
The environment will be quite speed-sheared with 500 J/kg ML CAPE for low-topped storms.
If we can get rid of the cap, MARGINAL RISK for low-topped, gusty line of storms along cold front may occur.
We will monitor.
50s should follow Thursday night to early Friday morning with a nice northwest wind at 10-15 mph.
We heat up for the weekend & Sunday gets very warm to hot & humid with 85-90.
Storms are possible in the afternoon-evening. Parameters suggest SLIGHT RISK for severe as a potential line of storms passes.
Storms are possible Monday with the actual cold front with MARGINAL RISK parameters for severe.
Some scattered showers/thunder are possible Tuesday with brisk northwest winds & highs only in the 70s.
Wednesday turns partly to mostly cloudy & it will be breezy to windy with highs of 68-76.
Multiple nights following may drop well down into the 40s.
