Actual highs today ran 81-90, exceeding forecasted highs of 80-86.

This had much to do with tongue of dry, sinking air that cleared the cumulus clouds out over Clinton, Tippecanoe & Fountain counties this late afternoon.  Dew points dropped from 65-70 to 55-58.

This, after a few showers & storms & the funnel reports from east side of Lafayette to near Russiaville.

In the MARGINAL RISK band from northern Illinois to central Ohio, much of the isolated severe weather was clustered from far southern Michigan, through LaGrange & Fort Wayne, Indiana to Lima, Ohio.  It is likely that some of the wind damage was caused by an EF0 tornado or two.

Upper 50s to lower 60s will occur tonight with areas of dense fog developing.

Fog will clear tomorrow morning with highs tomorrow at 80-85.  A few isolated showers/t'showers may bubble up tomorrow afternoon with risk of an isolated funnel.  It will still be a bit humid with dew points in the 60s.

Fog may develop initially Thursday night with temperatures tumbling from near 58 to 64. 

However, high & mid clouds will increase & thicken through the night with temperatures leveling off, then rising to 63-66 late.

A few showers are possible Friday morning after the fog disperses.

After a few of those showers, we may see a break, then a few storms in the PM & into Friday night.

Storms are possible at times Saturday to Sunday with dry time in-between.  Timing of the rounds of storms will determine whether they will be intensifying or producing any severe weather or weakening as they pass.

If they can pass at peak heating, risk of some severe weather will increase.

Some storms are possible at times next week, mainly early as late-season heat wave takes hold with high humidity driving heat indices to near 100 to the lower 100s.

Intense heat with high temperature anomalies will occur for many days in late August from the Pacific Northwest to Texas & then right over our area to Eastern Canada & the Northeast.

The near to below normal temperatures in southeastern Texas to Louisiana & Mississippi will be due to heavy rain & storms with potential tropical development.

That cooler air seen in Saskatchewan & the Dakotas still looks to plunge southward & bring cool, pleasant weather as we get to Labor Day.
