They have since been rescued; no injuries have been reported.

UPDATED (3:35PM) - Severe weather continues to push east through Mid-Michigan. Currently, in South Lansing, skies are clearing and the storms are east of us at WMMQ. Eastern Ingham County is still under a ST Warning until 3:45PM, Jackson County until 4:15PM. I have fielded calls from listeners in Calhoun County that are reporting trees and branches down with isolated power outages. mlive.com is reporting damage to multiple buildings in Portland, including the Rite Aid and Goodwill stores. As far as another round of storms is concerned, most meteorologists think it is likely as of now. wlns.com also reports damage in Portland and shared video.

UPDATED (3:05PM) - Add Eaton and Ingham Counties the severe Thunderstorm Warning list until 3:45PM. (details here) More storms are expected through the afternoon and evening...I will keep you posted.

UPDATED (2:45PM) - The first wave of storms held together long enough to cross Lake Michigan, leaving a few damage reports of downed trees and slight building damage to an apartment building in Kent County. But, the storm weakened in intensity as it moved towards Lansing, but the precipitation spread out. As the head of the storm passed east through Mid-Michigan around 2:00PM without much incident, a Severe Thunderstorm Warning has just been issued for Ionia and Clinton Counties until 3:30PM, (details here) and Shiawassee County until 3:45 PM (details here). A second wave of storms is still expected this evening, and could pack a punch. With this current storm issued, it demonstrates the instability of the air behind the initial storm front.

Original Post (11:48AM) - It's shaping up to be a stormy Monday for Mid-Michigan. Isolated severe weather threats exist for the entire Lower Peninsula today. Storms have produced damage reports already across Iowa, with wind gusts in excess of 70 MPH reported along with large hail. I have included a button to access wunderground.com and its Wundermap. This will allow you to see radar, storm warnings, and damage reports.

Mlive.com also has their meteorologist following the storms today. According to his article, Mark Torregrossa expects the storms to reach the West Michigan shoreline around 1:00PM this afternoon. But, he also expects the storms to weaken a bit as they make their way across Lake Michigan. This means it's all about the afternoon sun. If there is enough sun energy to keep the air unstable, storms could regain their strength as they move across the mitten.

A second round of Monday storms is expected in the evening hours as well. The main threat for severe weather is damaging winds 65-75 MPH, large hail, and isolated tornadoes are also possible. As always, we will keep you up to date all day on air and online as situations warrant.
