After 79-85 for highs yesterday, today reached 86-92.

Highs yesterday:

Highs today:

Heat indices today were impressive for September, reaching as high as 101 as dew points reached as high as 76:

Our peak heat indices for 2019 occurred in the late July heat wave:

A few spotty storms are possible any point in the viewing area Thursday morning to evening with sun/clouds.  Coverage will run 30-35%.

With 87-92 tomorrow (after around 71 in the morning for a low temperature), heat indices will peak at 93-102.

Given the decent wind fields aloft & heating, an isolated severe storm is possible.

After 7 p.m., any storms should be out of the area.

It does not look too capped, so it appears that any storm that pops won't have to struggle much.

A few isolated storms are possible Thursday with sun/clouds with coverage around 25%.

Highs will run 87-92 (low around 71 in the morning) with heat indices 93-102.

Outflow boundary from storm north of our area Wednesday night may bring a few storms to the north in the morning, the a few isolated storms elsewhere during the day.

Some capping may prevent more widespread coverage other than 25% Thursday.

Leftovers of severe weather west of us should pass late Thursday night-Friday morning as a weakening line of showers & storms.

A few new storms may fire on the actual cold front just barely southeast of the viewing area around midday-early afternoon.

It will turn a bit less humid by Friday afternoon with highs 83-87.  The relief from the mugginess may be a bit slow coming in.

Saturday looks good with partly cloudy skies, lower humidity & highs 79-83 after 55-60 in the morning with patchy fog.

Front will move back north as a warm front Sunday with a few isolated storms & highs 86-91 with heat indices 90-97.

A landfalling tropical system may bring widespread rainfall as far north as southern Indiana, Kentucky early to mid next week.

Here, looks very warm to hot & humid with a few spotty storms developing, especially Tuesday-Wednesday as cold front settles over area. 

This may keep the tropical remnants southeast of our area, but we will still get some storms.

The circulation of the tropical system interacting with the cold front will help convergence along the front to bring peak coverage of storms Thursday at 45%.

You have to watch those humid, very warm, juicy situations, too, for a couple rotating/funnel/briefly tornadic storms as the circulation of the remnants tropical system interracts with the wind shift of the cold front.

It still looks like a big change in late September as a couple of deep upper troughs bring much cooler weather in, forcing what could be a major hurricane in the Atlantic away from the U.S.

Below normal temperatures look to dominate late September to early October.

In the transition between the summer & fall weather, widespread rainfall & storms, with some severe risk, is possible.
