GRAND RAPIDS, Mich. (WOOD) — West Michigan, get ready: More snow is on the way to some counties, leading to a Winter Storm Warning and advisories from the National Weather Service.

Snow will develop ahead of weak system arriving later Thursday. It will get an extra boost from Lake Michigan, especially from Grand Haven northward.

There will be sharp contrast from the heaviest snow to the lighter amounts.

The expected snowfall and  adverse traveling has led to a Winter Storm Warning for Muskegon and Oceana counties and advisories for Ottawa and Newaygo counties.

For the second consecutive morning Thursday, we achieved a record low temperature in Grand Rapids, at -10 degrees.

Wednesday morning’s low of -12 degrees in Grand Rapids not only was the first subzero temperature of 2017; it also eclipsed the previous low temperature of -5 set in 1993 and is the coldest temperature on record since December 1983, when temperatures plunged to -18 degrees. It now has the distinction of being the third coldest December temperature on record.

West Michigan has the perfect recipe for frigid cold temperatures: a decent snow pack (5 inches in Grand Rapids and 7 inches in Muskegon) and a very light or calm wind.

With a massive area of high pressure drifting across the southern Great Lakes, a mostly calm wind Wednesday night shifted from the southeast, pushing any lake-effect snow and clouds hovering above land to over Lake Michigan.

Temperatures Thursday night will be cold but not as cold. I expect temperatures to hold in the teens along the lakeshore and near 10 degrees inland.

The weak system sparking the winter storm warnings and advisories will act to reinforce the cold air and below average temperatures throughout the Great Lakes region. If we do not hit 20 degrees Friday, it is possible we could go nearly two weeks straight with temperatures below 20 degrees.

If we look further ahead through the first week of January temperatures remain below freezing for highs with several mornings projected to go below zero.

More record cold is possible on the last morning of 2017.


The cold we’re experience also spawns some natural phenomena, including sun dogs and ice pillars.

Sometimes, both happen at the same time.

Sun dogs, also known as parhelions, are more common during sunrise and sunset. The light from the sun dog is red closest to the sun,  while areas farther out appear green and blue.

Sun dogs are fairly common in general, often forming as high cirrus clouds 20,000 o 30,000 feet move into Michigan. However, the more rare ones occur when surface temperatures are very cold. No matter where sun dogs form, they’re created when ice crystals bend (refract) as light passing through them at 22 degrees.

The show doesn’t always disappear at night. Sometimes during frigid, calm and clear nights, light will reflect through these ice plates, creating ice pillars and “moon dogs.”

The Grand Haven Area Convention & Visitors Bureau also spotted “pancake ice” along the iced over boardwalk leading out to Lake Michigan Tuesday.
