Relief from the heat while rainfall is still lacking

The most anticipated cold front passed Saturday afternoon putting an end to the four day stretch of triple digit heat.  Now the jetstream pattern has shifted a little with a ridge of high pressure in the west and a trough in the east.  This will keep temperatures in the Midwest and Great Lakes in the mid and upper 80s.  Unfortunately, while we'll receive a break from the oppressive humidity there appears to be no relief from the drought. 

A stalled stationary boundary extending from the southern Plains to the Mid-Atlantic will keep the heaviest of the rainfall in the south as gulf moisture runs into the front.  Closer to home the rainfall forecast is looking rather bleak.  As of Monday morning the rainfall deficit has moved closer to nearly five inches below average since June 1st and now over seven inches below since the beginning of the year.  While areas south of Rockford, closer to the I-88 corridor, have received some rain with the recent storms locations near the Wisconsin/Illinois border are really beginning to suffer.  With the current pattern in place there doesn't appear to be much relief in sight for rainfall.
