Dry stretch of weather continues

A stagnant weather pattern for the past three weeks has resulted in a large area of high pressure remaining in place over the Great Lakes.  This has provided a dry northeasterly flow to much of the Midwest and Great Lakes, keeping any rain-producing systems well to our south.  The last significant rainfall occurred on Labor Day weekend, and the current dry stretch is our longest rain-free period this year for much of the area.  The next chance of rainfall will be Sunday, especially for the southern and eastern parts of the state, as a low pressure system moves into Indiana from the lower Mississippi Valley.

Below is a listing of the longest dry streaks since 2000 for several locations in central and southeast Illinois.
