Scattered showers will develop this afternoon and evening (40-60% chance). Rainfall amounts should be relatively light, but these showers could produce gusty winds. Seasonably cool conditions continue into the weekend, and portions of the area could see frost develop the next few mornings. Temperatures trend back to near normal for Sunday-Monday, with additional chances for showers and storms. Despite this brief warming trend, below normal temperatures are favored to persist for much of next week.
Seasonably cool low temperatures in the mid to upper 30s may result in frost development across portions of the region the next few nights. The main concern for frost is still Friday night, but some patchy frost is possible tonight (mainly NW of the IL River) and Saturday night (eastern IL). If you have tender vegetation, consider covering your plants or bringing them indoors if possible.
Scattered, gusty showers will progress from northwest to southeast across the area this afternoon into the late evening. Rainfall amounts are expected to be less than a quarter inch, but showers could produce gusty winds (30 to 40 mph).
