Regional context

In Rayville, NOAA NCEI 1991-2020 normals put January near 26°F and July near 77°F — a 51°F seasonal arc — with about 42.1 inches of precipitation over 69 rainy or snowy days.

Summer convection drives Rayville's precipitation: May logs 6.3 inches on 8.9 rainy days, against January's 1.3 inches on 2.9 — warm-season storms carry Rayville's moisture. That puts Rayville in a summer-convective cohort with places like Vibbard, MO, Wood Heights, MO and Crystal Lakes, MO.

Around mid-April, Rayville sheds its freezing nights — kale, peas, spinach, and parsnips go into Rayville's beds. Tomatoes and peppers do best set out two weeks later in Rayville, once nights clear the mid-40s°F. The season ends by mid-November in Rayville, once hard frosts set back in. A creek-bottom lot in Rayville can lag Rayville's last frost 7-10 days behind a south slope.
