April 27, 2002: Big Snow after Record Flooding

By  | 

NEGAUNEE, Mich. (WLUC) April 2002 was a spastic month weather-wise across Upper Michigan. The month started cold after record March snows. Then a tremendous mid-month warm up set in with rain and record flooding. Another turn-around occurred at the end of the third week of the month with a six-inch snow in Iron Mountain on the 22nd. This snow was confined to northern Wisconsin and the far southern U.P.

The big U.P.-wide snowstorm occurred on April 27-28, 2002. Low pressure developed off the Rockies into the high plains of Colorado early on Saturday, April 27 and moved northeastward (Image 1 & 2). The air was cold enough for heavy snow to develop north of the low’s track through northern Wisconsin and most of Upper Michigan. A daily-record nine inches of snow again fell in Iron Mountain, while around 10 inches fell at the National Weather Service (NWS) near Negaunee. The snow was accompanied by thunderstorms in northern Wisconsin where some tremendous snows came down in a short period of time. Elcho in northeastern Wisconsin’s Langlade County received 20 inches of snow in the late night of April 27 into the morning into the morning of April 28.

This late April snow was followed by a cold May. The mean temperature at the NWS came in at 5.7 degrees below average.

This April is running cool—about four degrees below average. A very cold first 10 days was followed by a very warm eight days from April 14-21. Since then it has been chilly and with a strong high pressure system anchored over Canada, near to a little below average temperatures should continue.
