F ollowing an active start to the week in weather we may end the week stormy as well.
The National Weather Service Office in Gaylord has confirmed based on surveys of damage after Monday's storms that 4 separate tornadoes touched down across Northern Michigan making it the biggest outbreak locally since October of 2007. Three of the tornadoes were rated EF-1 indicating based on damage, winds of 86-110 mph in Kalkaska, Crawford and Otsego counties. A fourth tornado in Cheboygan County was rated EF-0 with winds of 80 mph.
Potentially more severe weather is on the way Thursday into early Friday and it may come in a couple rounds. A warm front will be lifting northward Wednesday night into Thursday morning. This will lead to the initiation of thunderstorms over Minnesota which will roll along/north of the warm front tracking overnight across Wisconsin/Upper Michigan with damaging wind potential. The million dollar question locally is whether these storms will make it into Northern Michigan without losing their strength. They may fall apart some before reaching our area. Even so it's worth watching closely.
Later in the morning/afternoon another round of storms may develop as the warm front lifts north crossing over the Eastern U.P. in the afternoon hours. These storms too may be strong/possibly severe although the threat here should be mainly north of the Mackinac Bridge.
What may end up being the most significant storm risk locally will be Thursday night as a strong cold front arrives. We believe thunderstorms will once again billow up over Wisconsin/Upper Michigan and track right across the area later Thursday night, most likely around/after midnight. There is a risk for damaging winds or large hail with these storms just about anywhere across our viewing area.
So to summarize:
1.) Round of thunderstorms Thursday morning possible areawide although they may be weakening
2.) Potential round of strong/severe thunderstorms over the Eastern U.P. Thursday afternoon
3.) Risk of strong/severe thunderstorms Thursday night across the entire viewing area.
Please keep aware of the weather Thursday into Thursday night.
