The year, day by day
Summer here tops out rather than builds: the warmest normal high is 90°F around July 23, short of 90°F on every date, while 204 dates carry a normal low at or below freezing, the coldest 11°F near December 23.
The freezing stretch
The normal low stays at or below 32°F into May 1, then returns to freezing around October 11, covering 204 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is May 21, when 26% of years recorded at least a hundredth of an inch. The driest is August 12 at 12%. Summed across the calendar, that is about 59 wet dates a year.
The widest day
August 28 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Any date's 1991–2020 normal for Midwest.
Where Midwest Stands Nationally
Winters bite deep and often: the normal nightly low dips to freezing or below on around 204 nights a year, placing this among the most frost-prone tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 37°F, sharper than nine in ten ranked stations see.

Midwest spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 12%, with neither reaching the 35% that would mark a distinct wet season. Midwest has no dry season to plan around, though it does carry a wide 46.7°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 2.5" and January 0.3". The three wettest months together take 44% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
How Midwest's precipitation splits across the calendar
About 58 days a year record measurable precipitation here, carrying 12.4" between them, or roughly 0.21 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Winter brings real snow to Midwest
Midwest averages 45.9 inches of snowfall a year, with February the snowiest month on the normals, spread across roughly 23 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 45.9 inches of depth.
- Days recording measurable snow: about 23 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 37% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Midwest
heating led · dry · mid swing
Midwest's energy balance leans toward cold weather: 7,663 annual heating degree days against 408 for cooling. Its 46.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 123 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
