Highs today ran 86-90.

Heat indices varied from around 90 to as high as 104.  The highest heat indices (& dew points as high as 77) occurred in Newton County where up to 6" of rainfall occurred lastnight.

One outflow boundary is surging out from the collapsed storms around Chicago & Milwaukee.  Another outflow boundary, albeit diffuse, runs from east-central Indiana through the viewing area.

This boundary is from the storms in our northwest counties lastnight & those storms' MCV (which moved over Ohio today).

The boundary has been migrating northward & has been trying to produce towering cumulus & isolated storms all afternoon to evening (you may have noticed some cumulus towers along it in the northwest & east & southeast potions of the sky this evening in our area).

We have been strongly capped this afternoon & into tonight, putting the kabosh on decent tall cumulus towers & any storms developing. 

At the intersection of the outflow boundary moving into our northwest & the diffuse boundary from Ohio, there are some cumulus towers noted as of 11 p.m.

An isolated t'showers MAY be able to partially break through the cap over the next few hours.

Otherwise, it looks just dry & partly cloudy tonight with lows 67-71.

Tomorrow looks hot & humid with highs 88-91 with heat indices 92-100.

Another outflow boundary from a complex of storm or MCS will move southward into the area.  This, with the MCS' cirrus shield in the morning before thinning.

The boundary may pop a random isolated storm through the cap.

It will be the same thing Saturday (highs 89-92.....heat indices 94-102) as another outflow boundary from severe storm complexes (MCSs) northwest & north of us pass.

Sunday-Tuesday look dry & partly cloudy with 90-94 with heat indices 96-104.

Some storms are possible Tuesday night & into Wednesday-Wednesday night.  Coverage should peak near 60% Wednesday evening.  An isolated severe storm or two is possible, but nothing looks widespread severe.

July Fourth look wet early, then partly cloudy & 82-86 with slow decrease in the humidity.

Hot, humid stretch is likely after that with some storms at times & then a turn to cooler, less humid weather mid-July (following a severe weather day in this transition).
