WEST MICHIGAN - A WIND ADVISORY remains in effect for our lakeshore counties through 2 A.M. Wednesday. We expect sustained winds at the lakeshore from the northwest at 15 to 30 mph, with some gusts of 50 to 55 mph during that time frame. Scattered power outages will be possible. There are STORM WARNINGS on Lake Michigan with waves 13 TO 17 feet! Make sure to stay off piers, jetties, and breakwaters.
Below is a snapshot from our forecast model of wind speeds/gusts/direction. The larger, whiter number shows sustained winds, the arrow represents the direction from which the wind comes, and the "G" number is the gust. The image is valid for 6 P.M. today. We believe the core of the strongest winds will come through this afternoon. '
These winds are being generated by the difference in air pressure between a low pressure system over the Great Lakes and a high pressure system over the northern Plains. Once the low lifts out of the region on Thursday, winds will diminish. See image below and the cold pool of air aloft being generated from a trough in our jetstream.
Our weather will improve significantly on Friday and for the upcoming weekend, but until then, we're plagued with clouds, wind, cold temps, and occasional rain and snow showers. See image below.
A rumble of thunder can't be ruled out the next two days, plus some wet flakes mixing in. Much of the Upper Peninsula has WINTER STORM WARNINGS in effect. Some areas there my see up to ten inches of snow.
