No, this is not some very belated April Fool’s Joke. It will snow in Illinois tomorrow.
Locally, we’re looking at mostly rain, but areas closer to Chicago and parts of southern Wisconsin will see upward of 6+” of snow tomorrow. Winter Storm Watches and Warnings are in effect for these areas.
Here’s what radar may look like throughout the day tomorrow.
It is possible that a few flakes may mix in locally late tomorrow evening, but again this will be a rain event for the Heart of Illinois.
Most of us have probably assumed that winter is now in the rearview mirror, and while at this point of April that is usually a good assumption, it has snowed at times in late April and early May.
Going back to when weather records began in Peoria in 1893, there has been a trace of snow or more in 12 years from this day (April 26th) and beyond. Those years are 1907, 1908, 1909, 1923, 1940, 1944, 1950, 1954, 1960, 1966, 1989, and 2008.
Of these snow events, only two have been measurable (0.1″ or more). We saw 0.1″ of snow on May 8th of 1923 and 1966.
1966 also had a trace of snow the following 3 days that year.
If we see any snowflakes mixing in late tomorrow, or possibly even the low chance of a light accumulation, it will likely be unwelcomed by many, but it has happened before this late into spring.
