April 5 in Homewood sits right in the heart of spring's unpredictability — the average high is a mild 54° but this date has swung anywhere from 18° in 1995 to a t-shirt-worthy 76° in 2005. There's roughly a one-in-three chance of rain today, but snow is effectively off the table.
Homewood's weather has real teeth on both ends: the thermometer has touched 103° in the brutal summer of 1988 and cratered to -27° in January 1985, a 130-degree spread that speaks to the full force of the continental Midwest climate. A single July storm in 1996 dumped 6.55 inches of rain, and a February 2011 blizzard buried the area under 19 inches of snow in one day.
Summer is the main event here — the warmest week of the year runs July 16–22 with average highs of 85°, and that same stretch is also the wettest, averaging 1.29 inches of precipitation. Winter bottoms out mid-January with average highs of just 29°, so plan accordingly. Spring and fall offer a brief but pleasant shoulder season, with April and October highs landing around 59° and 64°.
