April 5th in Springfield sits right in that volatile spring sweet spot — 125 years of data puts the average at a mild 59° high, but this date has swung wildly from 86° (1988) to a brutal 17° low back in 1920. There's nearly a coin-flip chance of rain today, with a lingering 5% shot at snow that feels unlikely but isn't out of the question.
Springfield doesn't do anything halfway — the all-time record high of 112° in July 1954 and a bone-chilling -24° in February 1905 represent a staggering 136-degree range in observed temperatures. August 2016 brought the wettest single day on record at 5.59", while March 2013 buried the city under 17" of snow in one shot.
Springfield peaks in the heat of mid-July, when average highs hit 87-88°, and bottoms out in mid-January around a frigid 34°. If you're trying to avoid rain, steer clear of early June — the wettest stretch of the year averages over an inch of precipitation in a single week. Spring and fall offer the most comfortable windows, with April and October highs landing in the comfortable 60s.
