WEST MICHIGAN — The weekend forecast continues to look quite wet and windy at times. The first round of wet weather arrives later this Friday evening in the form of showers ( a few rumbles of thunder cannot be ruled out overnight ) and carries into early Saturday morning. This round of rain will likely bring between .50" - 1.00" of water before it tapers back around daybreak Saturday.
We should see a bit of a lull in the action for the mid-late morning / early afternoon time frame before more activity shifts into West Michigan by late afternoon. This second push of moisture will bring back showers and even the prospect for a few thunderstorms as the evening unfolds. Heavy downpours can be expected.
Though the prospect for severe weather looks to remain on the low side, a couple stronger storms could materialize across southern sections of the viewing area ( say especially south of I-94 ) where temperatures and dew points will be the highest. If any stronger storm does materialize, hail and gusty winds would be the threats.
Expect another .50" - 1.00" of rain with this late Saturday afternoon/evening round of wet weather for 24 hour rain totals of 1-2" or so. Showers will diminish during the very early morning hours of Sunday as a dry slot works into our region from the south and the west.
The overall synoptic, or large scale low pressure generated, wind field associated with this weekend system will be quite strong. Noticeably breezy east to southeast winds through much of Saturday will shift to the south and eventually southwest later Saturday evening while cranking up further. This will help to push temperatures to mild levels around 60 degrees for the late evening and very early morning hours on Sunday.
Thereafter, southwest flow will be quite brisk especially late Sunday morning and early afternoon as winds crank to 20-30 mph with gusts to 35-45+ mph. These winds will slowly shift more westerly through the afternoon as cooler air gets drawn into West Michigan. Morning temperatures in the 50s will drop into the 40s for the afternoon. Some additional scattered showers will also be around on Sunday keeping things pretty raw outdoors, before tapering through the evening.
A Lakeshore Flood Advisory will likely get posted for the Lake Michigan shoreline for Sunday for beach erosion and localized low-lying flooding.
