Lows this morning ran 33-44 with patchy dense fog & even some patchy frost as temperatures tanked in areas with clear skies & a calm wind. The official low at Greater Lafayette was 37.
Patchy frost will occur tonight with lows 33-39.
On-going forecast below seems good. I just tweaked tonight's lows a hair from 34-38 to 33-39. I will have another post later today with as another round of new data arrives.

The latest US Drought Monitor is out & it shows Moderate Drought over northeastern counties & now in our southern counties. It is Abnormally Dry elsewhere.
Since latter August 2012 turned so wet, now June-September 2020 is the driest such period since 1999 for the viewing area as a whole with 3-8" deficits since May.
13 Indiana counties are under Burn Bans, the closest to our viewing area being Vermillion, Parke & Tipton counties.

Lows this morning ran 36-46, coldest readings that stayed clear all night with the lightest winds.
Highs today reached 59-67.
A scattering of showers & t'showers today (some gusty with a few of some graupal to small hail) will continue to taper tonight. After a windy day, winds will continue to diminish tonight with some fog & lows 37-44 (with variable clouds).
Friday looks partly cloudy with northwest wind at 9-20 mph & highs 56-62.
A few clouds may linger tomorrow night, mainly in the north & northeast, with fog patches & lows of 34-39 (coolest south & southeast & around 37 at Greater Lafayette.
Some patchy frost is possible.
Partly cloudy skies should become mostly cloudy with time Saturday with very light east-southeast wind quickly turning to the south to south-southwest & increasing to 10-20 mph late. Highs of 61-67 are expected.
A wave of scattered showers is still expected Saturday night to early Sunday morning with lows of 48-54.
After early showers, it appears that cold pocket aloft will pivot through with a scattered of showers & even a few isolated storms with small hail risk will pop up.
With mostly cloudy skies overall, highs will run 58-66 with breezy to windy conditions.
Rainfall totals look to run 0.15-0.40". A couple/few isolated amounts of +0.40" are possible.
After a nice Monday with mostly sunny skies & highs of 64-69, an Alberta Clipper will move through quickly Tuesday with strong southwest to west winds, even warmer weather & just a few isolated showers.
Very warm, dry pattern takes over mid to next week through the next weekend with temperatures climbing to the 80s with strong southwest winds.
Record heat is possible from South Dakota & Iowa to Nebraska with 90s & some places nearing 100.
High field & brush fire danger will occur in these areas, as well.
Still looks like a shot of cooler air coming in around October 17 with colder than normal temperatures skimming by us. A night of 29-35 is possible.
Meanwhile, record heat with brush, grassland & forest fire danger, shifts back to the west, but more for the Intermountain West & Northern Rockies to southern High Plains.
Warm surge works back eastward with temperatures shooting up well above normal around October 20-21.
