Still looks like potential of intense heat wave ahead, but really, it is sort of a continuation of what we will already have this weekend & this upcoming week, it will only worsen.

Only the remnants of Barry skimming by & a weak front washing out over the area will disrupt it in any way.

_________________________________________________________________________________

So..........

Highs today ran 86-92.  We reached 91 at the Purdue Airport. Most of the area hit 90-91.  The hot spot was Morocco at 92.  Only Crawfordsville, Rensselaer Fowler & Logansport all just fell short of 90.  All other observation site hit or just exceeded it.

__________________________________________________________________________________

As of 10:30 p.m. a few showers & storms are moving into our far northern fringe.

A few spotty storms are possible tonight on the periphery of the intensifying heat wave over the area with around 30% coverage.  An isolated severe storm is possible (wind, hail).

They will collapse tomorrow morning, then may re-fire tomorrow afternoon (30% coverage) to evening before collapsing again.  A couple of isolated severe storms are possible tomorrow afternoon-evening (wind, hail).

Tomorrow night looks completely dry.

Skies look partly cloudy overall tonight through tomorrow before going mostly clear tomorrow night.

After lows tonight of 68-73, highs tomorrow will tend to run near 90-95 with high humidity making it feel more like 99-105.

After 90-95 Monday (heat indices 97-102, as we may dry some with some dry, sinking air on the periphery of the Barry remnants), the remnants of Barry skimming by will bring some periodic showers & storms Monday night, Tuesday & into Tuesday night.  Coverage will average 45-50%.  Rainfall will be quite variable, but it still looks like a few random locations under the heaviest storms will see +2".

Highs Tuesday should be held down a bit more by more clouds & showers/storms bubbling up around the area with 87-91.  Heat indices should peak at 95-101.

A few storms are possible Wednesday as a very weak cold front tries to sneak it, but it will tend to wash out over the area as strong, hot upper ridge expands over the area.

Highs will run 90-93 over the area with heat indices of 99-105.

By Thursday, it will be settling in with a long-lived complex of severe storms tracking along its periphery from western South Dakota to Ontario in the "Ring of Fire".

We should be strongly capped & mostly sunny with highs 91-95 with heat indices 104-111 Thursday.


The upper ridge should strengthen & result in a widespread, substantial heat wave from the Plains to the East Coast.

Multiple cities may see their first 100-degree day since 2012, including Chicago & New York City with heat indices +107.

Even with all of the wet soils & lush vegetation around D.C. they could still hit 100 with very high heat indices of +110 given dew points in the 70s.

Our viewing area:

Day:  Projected highs....Projected Peak Heat Indices

Friday:  92-97....104-110

Saturday:  94-99....106-112

Sunday:  93-98....101-109

Monday:  88-92....97-101

A round of organized storms (MCS with some severe weather) may gut some of the heat Monday as it passes potentially Monday morning or midday.

There will be a strong cold front & upper trough that pivots through & eventually changes the pattern toward cooler & wetter weather.  That will most likely pass after July 26 with round of storms (some severe).

After July 26 & through early August still looks to be a cooler-than-normal, wetter period overall.

We may not see another round of intense heat until late August (highs in the 90s).
