A few storms are occurring as of 1:40 a.m. from Lafayette to Frankfort & Indianapolis, as well as one storm in northeastern Jasper County.
A few storms will persist to around 3 a.m.
Any severe risk would be isolated.
Lows will run near 70 to 75.
MCV from Plains complex of storms & complex near St. Louis will pivot through eastern Iowa & northern Illinois Sunday morning-afternoon.
Severe storms will likely fire with it & tail end of the MCV's severe storms may clip our northwestern & far northern counties in the 5-9 p.m. time frame.
Wind/hail risk will accompany the storms, though brief tornado cannot be ruled out given us being on the edge of the enhanced shear & vorticity of the MCV.
Only fly in the ointment is the strong capping that may be a bit hard to completely break here.
Otherwise, looks like partly cloudy skies, strong southwest winds to 35 mph & highs 88-95 with heat indices 94-103.
Then, supercells will congeal into a line & affect our area 12 a.m.-5 a.m. Sunday night-early Monday morning.
Line will eventually weaken as the winds surge out of it as it moves through the area. This gust front eventually surging out of the line will choke away its updrafts as the better mid & upper wind support begin to migrate toward northern Ohio, southeastern Michigan & Ontario.
The line looks to produce severe weather, but the best threat is the farther north & northwest you go in our viewing area.
Main threat is wind, but a brief spin-up of a tornado cannot be ruled out in a kink &/or embedded large nodule in the line.
Lows will run 67-73.
A couple/few spotty showers in the morning to midday may give way to scattered showers Monday afternoon.
It looks partly to mostly cloudy then mostly cloudy to cloudy with highs 70s to around 80 with strong northwest wind 25-37 mph.
Tuesday looks nice before heat returns mid to late week with high humidity.
A couple storms are possible Wednesday as ridge expands again & warm front passes through.
We may be clipped by a "Ring of Fire" complex of storms Friday with severe risk in the north.
Line of storms with severe risk is possible Saturday.
Cooler, less humid weather will follow until heat of 90s returns as we approach July 4.
