Anthony Rice:

Lows this morning ran 68-72 with patchy dense fog, followed by highs this afternoon of 86-92.  Heat indices peaked at 92-105.  The highest dew point at any of the observation site was 77 at Fowler, Covington & Kokomo Municipal Airport.

Risk of a couple isolated funnels to even a landspout will continue up to about 8 pm this evening, then occur again tomorrow with a few spotty t'showers.

After 66-71 tonight with patchy fog & an isolated shower possible, highs tomorrow will run 87-93 with heat indices of 93-106.

After patchy fog, a couple isolated t'showers are possible Friday afternoon-evening with highs 88-93 & heat indices reaching 94-107.  Isolated funnel is possible.

By later Friday evening, line of severe storms will be approaching the the Mississippi River in Iowa & northeastern Missouri.

Wildfire smoke may impact storm coverage/strength there.  However, it may also enhance tornado risk if smoke is concentrated in the lower levels.

We do not see much wind Thursday-Friday, so it will feel quite stifling outside.

As of right now, I am keeping storm risk to late Friday night-Saturday morning as what is left of the severe weather Minnesota to Missouri arrives.

Right now, parameters suggest MARGINAL to SLIGHT RISK for severe in our area.

The best wind fields & shear for severe weather will be displaced northwest of our area, but we will still be unstable & in a region of rising air motion caused by diffluence aloft, despite core of surface & upper low tracking through Manitoba & western Ontario.

If the storms slow down, there is potential that they would pass a bit later than late Friday night-Saturday morning & heating could even intensify the storms further.  We will monitor.

Again, wildfire smoke is a bit of a wild card regarding storm coverage & strength to even the main threat.  Thickness of the smoke & placement of thickest wildfire smoke are the biggest factors.

Slightly less humid air will follow storms with wind turning to northwest for a time.  Highs of 85-90 are expected Saturday with heat indices more like 88-94 by later afternoon.

After 60s Saturday night, 85-90 is expected Sunday.  The weak surface cold front that passes Saturday will move back north as a warm front later Sunday.  That could pop an isolated storm or two & high humidity will make it back in by later Sunday.

As for Monday, it looks hot & oppressive with highs 90-94 with heat indices 95-108.  Winds will be south to southwest 8-13 mph.

Storms are possible late afternoon-evening Monday.

Parameters suggest up to SLIGHT RISK.

Storms are possible again Tuesday afternoon-evening.  Highs of 91-95 are expected with heat indices of 96-111 with south to southwest wind at 10-15 mph.

Parameters suggest up to SLIGHT RISK. 

Heat may be cut (brief stint at highs 77-83 with lows in the 50s) with round of storms with surface cold front before it returns.

The first half of September continues to appear warmer & drier than normal with brief near/record warmth day &/or night.

Distinct change occurs mid-September with a nice burst of cooler, fall-like weather after a round of storms (from 90s one day to lows in the mid 40s in a couple of days).  At the end of September, above normal temperatures return.

October looks warmer & drier than normal.

Again, majority of the tropical risk will see a shift from the Pacific & western Gulf to more Florida to East Coast & the Atlantic with time.
