High pressure remains over the eastern half of the United States. With the ridging not going anywhere any time soon, clear skies, very light winds, and dry weather will continue across the state into the weekend. Overall, perfect weather for the latter half of harvest season. The main focus of this forecast is the temperatures and lack of rain.

Temperatures will continue to warm this week. Lows tonight will be in the mid 40s. Highs tomorrow into the weekend will range in the low to upper 70s. Normals for this time of year is around 65-69 mid across central and southeastern IL. Dry weather will last through the extended period.

Looks like a cold front will try to makes its way into IL around Monday, but with how dry the airmass is, it will have a hard fight to squeeze out any impacted rainfall as it passes. Chances for rain for late weekend/early week is null.
