Heat wave summary.....................
Actual air temperatures peaked at 91-97.
At the station in West Lafayette, peak temperature was 94 with peak heat index of 110.
Heat indices peaked at 104-116.
Skies should continue to clear from northwest to southeast over the area.
After a breezy evening, winds will decrease overnight.
Lows will drop to 54-58.
As for tomorrow, after a mostly sunny to sunny start, cumulus clouds should build pretty quickly in the late morning to midday hours as shortwave approaches from the northwest (cold pocket aloft).
Humidity will be low tomorrow with dew points in the 50s with highs 79-84, but a couple/few isolated showers/t'showers are possible in the afternoon-evening.
Clouds should then burn off, & after a breezy day (northwest winds 15-25 mph) lows of 55-60 should follow tomorrow night.
After a mostly sunny to sunny start, cumulus clouds will bubble back up again on Wednesday with a weaker shortwave pivoting through & highs of 81-86 (with still low humidity of dew points 55-61).
Cumulus depth does not look sufficient enough for any isolated showers or t'showers at the moment, however.
After brief cooling, burst of upper ridging means potentially 5 consecutive days of 90 or greater temperatures with warming aloft leading to mostly sunny skies. Thinking actual air temperatures over the area will peak at 91-95.
Heat indices should peak at 99-105 by early weekend & early next week.
Two surface cold fronts with a pretty deep upper trough will swing in & bring a cooler, wetter pattern in early August.
These will bring some rounds of showers & storms Tuesday-Thursday of next week. Isolated severe weather is possible Tuesday.
After a respite from the heat & drier weather, hot upper ridge may center over the are for a while in late August.
This may bring a streak of 90s with heat indices near 100 to 105.
Currently thought is that temperatures will peak at 92-97.
This still looks like this hot pattern could last to near Labor Day before breaking down with cooler & wetter than normal weather into early September.
