Stephenson County
Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
Across the county, corn is between VE and about V4 while soybeans are yet to emerge or at about V1. The rainfall received over the past couple weeks has been well received – the crop looks healthy and green. Surprisingly given the rain, there aren’t yet any significant weed flushes, but scouting is recommended to identify any moving forward.…

LaSalle County
Soil Conditions: Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
It has been a wet and chilly week following the hot, dry weather last week. LaSalle County saw nearly 5 inches of rainfall, which has led to ponding in some of the more low-lying areas of fields. Nearly all corn acres are planted, with most corn around stage V1-V2.…

Temperatures have been in the upper 70s and low 80s this week with lows in the upper 40s and 50s. There are some potential rain events coming in the next week to add some moisture back into the soil.…

Ogle County
Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Northwestern Illinois is in the home stretch of planting. I’ve been able to row quite a few corn fields, and beans have been reported as being up and out of the ground or just about. There are few fields that have yet to be planted.
Weeds such as giant ragweed and common lambsquarters are present in fields I’ve been in,…

The final week of April acted much like the rest of the month, with warm and wet weather pretty much statewide. Average temperatures this week ranged from the low 50s in northern Illinois to the mid-60s in southern Illinois, between 3 and 6 degrees above normal. The entire month of April ended around 0.5 degree warmer than normal statewide.

A continued active storm track brought multiple rounds of showers and thunderstorms this week. 7-day totals ranged from around a half inch in parts of western Illinois to over 4 inches near the Metro East area.…
