May is nearly as busy as April in the variety of weather gyrations to be expected. Most Mays record at least a few snowflakes, and about every 5 to 10 years some accumulating snow. Likewise, temperatures approaching 90 occur once or twice in a decade. Most of the time May’s weather is categorized by passing cold fronts, preceded by warmer weather, accompanied by a period of showers or even thunderstorms, and followed by a fresh, cool breeze that might bring the final frost of the year. Should a late-season storm organize, a cold rain will brighten the green grass, and awaken the black flies.
