Our first fall freeze here in central Illinois is right on "schedule" based on the latest climate normals. Sub-freezing temps this morning were 1-2 weeks ahead of normal in places like Cahokia Heights and Carbondale.

FARMERS: There is a major need for hay / resources for livestock in the wake of Hurricane Helene. I've been told by a colleague in the southeast that "a convoy of hay from the Midwest would be a welcome sight".

Ever wonder where our weather balloons go after we launch them? Typically, they will land somewhere in central or eastern Illinois, or western Indiana. They tend to go farther in winter, when winds aloft are stronger. #ILwx

#Drought has expanded rapidly in the Midwest. Maps show today (left) & just 4 weeks ago (right). Many locations had 2-3 categories of change in that short period. Serious threats developing for ag, water supply, river navigation, fire risk, etc. #agchat #MidwestClimate

The Champaign NOAA Weather Radio WXJ-76 is back on the air! We thank the tower crew and our electronics staff for the extended hours put in this week to ensure the antenna and cable repairs were completed while the weather cooperated. weather.gov/ilx/nwrcmi #wxIL

Through May 1st the state of Illinois has seen 90 tornado warnings issued. That's good for #2 to date over the last 20 years, and on pace with some of the more active storm seasons locally like 2004, 06, 08, and 11.
It's been quiet the last couple weeks - will it pick back up?
