DISCUSSION
Issued at 225 PM EDT Sat Sep 5 2026
On the front edge of a ridge tonight, and back edge of upper trough over New England. Consequently, high pressure will be in control, drifting across the Canadian Shield into the morning. Chance for some late fog tonight, mainly across eastern upper potentially leaking down into Pellston and vicinity, and then across the Interior near West Branch and vicinity. Overall should be a brief concern during an otherwise calm and chilly night.
High pressure aloft continues to build over northern Michigan early next week with raising heights, keeping the seasonably warm conditions around. At the same time, conglomerate of energy ejects out of the PacNW into the N Plains around Tuesday. Response will be a sub 1000 mb low pressure system drawing an anomalous corridor of moisture (+3.0 sigma PWs) northward into the Upper Midwest and Great Lakes Region later-ish Tuesday into Wednesday.
Warm, moist advection later Tuesday into Wednesday combined with an approaching frontal boundary will lead to showers and embedded thunderstorms. Corridor of modest instability will aid in locally higher rainfall rates, especially given the anomalous column moisture. That being said, current ENS guidance has a relatively low probability for rain over 0.5", highest probs favoring the E UP. Nevertheless, widespread precip chances appear likely during this time frame.
In addition to the precipitation chances, combination of sfc high pressure sliding off to the east and approaching low pressure mid week will result in a tightening pressure gradient and increasing winds aloft. Consequently, sfc winds will increase, with breezy southwest to west winds on Wednesday, with gusts 30+ mph currently in the forecast.
Cooler airmass filters in behind the mid week system, with Thursday being the coolest day. Few showers will be possible as well as a short wave dives across N MI. Tranquil for at least a day or two before the next system/energy influences the region.
