Yesterday's official high of 72 was the third coolest August 1 high on record since 1879 for Greater Lafayette. It was the coolest high for August 1 since 1979 when the high was 71. The coolest August 1 high occurred in 1965 with 68.
The cool weather on August 1, 1979 just followed the flooding rainfall from the remnants of Tropical Storm Claudette. The flooding was the worst in the southern part of the state with damage in the millions of dollars.
On August 1, 1965 the morning low was 54 & it was a cloudy day with a trace of rainfall following cold front passage. However, by August 5, the high reached 93 with a morning low of 66!
Rainfall totals from Friday night to Sunday morning vary from 0.30-2" over the viewing area. Heaviest totals were in our far western & southwestern areas. Lightest amounts were in the eastern areas.

Hotter & muggy weather returns at the end of next week to next weekend.
Multiple rounds of storms are possible next weekend to early next week as clusters & complexes of storms occur on the periphery of the heat.
It looks like some MARGINAL to SLIGHT RISK at times late Saturday through Tuesday of next week.

There are still signs of mid-August cool-down, then a couple rounds of pretty intense heat in late August & early September.
Spurt of cool weather should arrive in mid-September with overnight lows in the 40s.
Late August to mid-September currently shows a tendency for normal to slightly-below normal rainfall.
