April 4 in Urbana splits the difference between winter's last gasp and a genuine spring day — the average high of 57° sounds pleasant, but records show this date has swung from 19° (1903) to 81° (1929). There's a 42% chance of rain today, though snow is nearly off the table at just 2%.
Urbana's weather has real teeth at both ends: the all-time high of 109° on July 14, 1954 is brutally hot, while the -25° recorded on January 19, 1994 ranks among the most punishing cold snaps in Illinois history. A single day in August 1993 dumped 5.32 inches of rain, and a March 1906 snowstorm buried the area under 14 inches.
Summer is the main event here — the week of July 9–15 averages a high of 86° and is also the wettest stretch of the year, so pack accordingly. Winter is genuinely cold, with January and February highs stuck in the mid-to-upper 30s. If you want warmth without the humidity and storms, late May and September are your sweet spots.
