Volatile fall weather ahead

A touch of frost may have occurred in central Nebraska this morning as temperatures dipped down to 32 F. in low-lying areas. The northwestern Corn Belt is looking for warmer and drier weather this week. Tuesday will be very windy. A large part of the western Corn Belt can expect sunny skies with warmer temperatures this week.

The next chance of rain arrives on Friday or Saturday with the threat of scattered thunderstorms with most rainfall amounts less than 0.25". In the central regions of the Corn Belt, some drizzle is expected this morning followed by dry conditions through the rest of the week. Skies will become mostly sunny today with temperatures reaching the middle to upper 60s. Sunny skies are expected the rest of the week with temperatures warming into the 70s.

In the eastern Corn Belt, an upper-level disturbance will shift across the region today, bringing some light showers or sprinkles to southern Michigan, northern Illinois and Indiana, this morning. Skies will clear out this afternoon and remain generally clear through much of the upcoming week. Today will be the coolest day of the next several days as highs struggle through the 50s to reach the upper 50s to lower 60s. Warmer air will quickly return the remainder of the week with highs climbing back around 70 degrees Tuesday and into the 70s Wednesday through Saturday. A cold front will try to move toward the area late in the weekend, but timing of the best rain chances may not be until Sunday night or Monday.

By Friday, a storm system should intensify over the northern Plains with some scattered showers over Minnesota and northern Iowa. Rain could increase across Iowa moving north into Minnesota on Saturday night and Sunday. Most rainfall amounts are expected to be light (less than 0.25"). The next storm will slowly develop over South Dakota, Nebraska, and Kansas by the middle of next week with cold rain over the Dakotas and heavier showers increasing across Kansas, Missouri, and Iowa by Wednesday, October 16, with 0.25 to 0.50" amounts.

It will take several days to dry the soils across the Midwest. The warm and dry weather should help bring most crops to maturity. The crop may be slow to dry down as temperatures should remain above freezing for the foreseeable future. Harvesting conditions should improve during the week.
