The heating of the day and the presence of a 'pool' of cooler air aloft activated scattered showers and storms Monday afternoon amid a drier and breezy air-mass.  The rain threat will continue to diminish as we have passed the heating of the day.

Clouds build over Boone county and the Golf Club of Indiana Monday afternoon. A few scattered thunderstorms developed during the heating of the day.

MILDER AIR

It is a much more refreshing brand air the has been ushered in on the west winds Monday.  A huge drop in dew point temperatures means it is much more comfortable air and will drop tho the coolest levels here in a week and a half.  The A/C takes a break overnight as low temperatures dip into the 50s by daybreak Tuesday.
