WEST MICHIGAN — Most of the U.S. will ring in Spring on Saturday night. Spring begins at 11:30 PM Central Daylight Time tomorrow night, 10:30 Mountain, and 9:30 Pacific. Here in West Michigan, however, Spring begins just after midnight on Sunday morning… at 12:30 AM.
The first day of Spring is also known as the Vernal Equinox: A time when the sun’s most direct rays pass over the equator, heading towards the northern hemisphere for the remainder of the season and into the Summer months. The progressively higher sun angle through spring means our average high and low temperatures will continue on an upward trend for the next three months or so. Our average high and low today, for example, are 45° and 27°. By May 1st, those averages rise to 65° and 43°, and to 81°/60° by June 21st (the first day of Summer).
Despite these averages, temperatures can vary widely on a day-to-day basis here in Michigan. For example, some snow is possible on Sunday night with some lower 20s possible in spots, and Monday’s forecast high of 40° would be the coolest we’ve had since March 5th when the high was 35°.
