Our final week of spring could be an active one with rounds of thunderstorms in the forecast, some possibly on the stronger side.
One sure thing is that Monday may well end up being the best day of the week with zero chance for any rain locally. Weak high pressure will build in with the passage of a frontal boundary that brought a few showers/isolated storms to the area Sunday night. With that being the case sunshine will prevail Monday with high temperatures ranging from 72F at Cheboygan to 82F at Big Rapids.
Much more turbulent weather rolls into Northern Michigan late Monday night into Tuesday. Thunderstorms will initiate Monday over parts of Nebraska/Kansas and track across Minnesota/Wisconsin Monday night following along a frontal boundary right into Northern Michigan. The latest thinking is that a line of thunderstorms will roll into Northern Michigan a couple hours before sunrise (in the 3-5 a.m. timeframe) Tuesday morning. The biggest concern with these storms would be the potential for strong or possibly damaging winds if they maintain their speed and intensity through the overnight hours as they approach the area. There could also be some hail with any storms that sweep in along with very heavy rain. This line of storms will cross west-east across Northern Michigan Tuesday morning. It's possible a few isolated storms may bubble up Tuesday afternoon.
Another round of thunderstorms could develop Wednesday, but high pressure over Northern Ontario will push the frontal boundary a bit further south Wednesday so the focus for storms Wednesday would lie mainly along/south of highway M-55 with very little if any rain up in the U.P./Straits region.
If you live in or are visiting Northern Michigan Tuesday and Wednesday, keep a closer eye on the weather the next couple of days as any storms could possible become severe and also drop very heavy rain in a short amount of time.
