With increasing clouds this afternoon highs should run 62-70 northeast to southwest.
A few isolated showers are possible later today, followed by scattered showers & t'storms overnight to early Tuesday morning.
Isolated large hail is possible largely north of Indiana 18 where t'storm coverage will be the greatest.
SPC has MARGINAL RISK up for large hail (1-1.75" diameter in this case) from an Earl Park to Brookston to Kokomo line & northward.
Lows tonight should drop to 50-64 from northeast to southwest with warm front draped over the area & then a migration northward.
T'Storms should blow up in Michigan Tuesday mid-evening with hail, wind & isolated tornado risk.
Here, any shower is confined to before midday Tuesday, followed by partly cloudy skies, southwest winds to 40 mph & highs 74-79.
Some data, like the NAM 3km below, suggest the storms in Michigan move east-southeastward & miss our area, then new line with severe risk (wind) forms along & south of I-70 & we miss everything Tuesday night.
I am perplexed by this notion in the NAM & some other models.
My thoughts are that Michigan supercell cluster backbuilds & elongates westward & sweeps area Tuesday night with a severe wind gust threat.
So, SLIGHT RISK for our entire area makes sense.
Temperatures will be warm Tuesday night at 65-70 with south-southwest winds to 40 mph.
Wind will turn to north behind front with gusts to 40 mph possible.
Showers & t'storms are likely Wednesday afternoon-evening.
SPC has any MARGINAL to SLIGHT RISK southwest ot south of our area, but I do think that at least MARGINAL RISK will be expanded into part of the area for wind & hail & even an isolated brief tornado along warm frontal zone.
Highs should range from 60 north to 75 south with northeast winds north to southwest winds in the south.
After this, temperatures tank to 30s Wednesday night with northwest winds gusting to 45 mph (isolated +50 mph).
Late next week looks chilly with partly to mostly cloudy skies, breezy conditions (even a few sprinkles & flurries) with highs in the 40s & lows in the upper 20s to 30s.
