Summer feel in the air through tomorrow before storms arrive
Although much of this summer has trended somewhat cool, a brief taste of heat/humidity will be in place through Tuesday before a round of thunderstorms sweeps it out.
Winds over the weekend have turned south-southwest drawing northward both warmer and much more humid air. High temperatures Monday will shoot into the low/mid-80's but there will be a marked increase in humidity which we will feel. Outside of a few passing clouds, it remains dry with no chance for any rain locally. Very little changes Monday night with a warm/muggy night on tap as lows will stay in the 60's overnight.
Upstream, a cold front will start to drop towards the area late tonight. This will lead to an outbreak of severe thunderstorms over parts of North Dakota/Northern Minnesota into Western Wisconsin late Monday night. This line of storms will be falling apart by mid-morning Tuesday when they arrive here, but a little rain or a rumble of thunder is possible in the morning.
For Northern Michigan, our best chance for thunderstorms will be Tuesday late afternoon/evening with storms likely redeveloping along that cold front as it passes by. Before that happens though, we should get back well into the 80's Tuesday with dew points in the upper-60's making it feel really sticky. Thunderstorms will cross from north to south mainly in the 6 p.m.-midnight timeframe Tuesday. At this point we do not believe there will be much severe weather threat, but a few storms certainly could be on the stronger side later Tuesday.
The humidity will start to drop Tuesday night with temperatures by Wednesday back into the low-70's with morning clouds giving way to some sunshine. Temperatures remain in the 70's Thursday/Friday with dry weather.
