April 5 in Rolla typically lands right in the middle of spring's transition, with average highs of 62° and lows of 41°.

There's a 36% chance of rain today, though snow is nearly off the table at just 1%.
Rolla's weather history is not for the faint of heart. The thermometer has swung from a scorching 113° in July 1954 to a bone-chilling -24° in January 1912 — a 137-degree spread that tells you this is serious mid-continent climate. The wettest single day on record dumped 7.9 inches in July 1998, and an early-season snowstorm buried the area under 15 inches on November 6, 1951.
Summer is the undisputed headliner here, with late July averaging highs of 90° and the overall peak running through most of June, July, and August. If you're cold-averse, avoid January through February, when highs only reach the low-to-mid 40s. Pack an umbrella for mid-May — it's the wettest stretch of the year, averaging over an inch of precipitation in a single week.
