DISCUSSION

Issued at 155 AM EDT Tue May 26 2026

Pattern Synopsis:

Shortwave troughing will slide across Ontario/Quebec today as a second wave looks to dig over the Great Lakes through the middle of the week. These features are embedded in a large scale pattern characterized by expansive amplified ridging encompassing much of the central U.S. and Canada -- and only looks to become more expansive and amplified with time through the forecast period. At the surface, a relatively weak cold front looks to drop from north to south across the region later today/tonight. With the Great Lakes being placed squarely under the ridge/trough inflection point come Thursday, surface high pressure will dominate late this week and this upcoming weekend underneath subsidence aloft.

Forecast Details:

Another warm day is in store for northern Michigan today underneath sunny skies for most of the day. Southwest winds will gradually turn to west winds ahead of the aforementioned front today, gusting to 20- 30 mph at times through the afternoon. Diurnal heating should be enough to result in a strong enough pressure gradient to force lake breeze penetration a few miles inland from the Lake Huron shoreline late this afternoon/early evening despite relatively strong west winds likely holding the boundary close to the lakeshore. As the cold front sags south with time later today, isolated showers/storms cannot be completely ruled out -- mainly across northwest lower where storms are expected to fire west of Lake Michigan and may work into the west side of the state. Given weak shear and a strong low- level inversion over the lake, confidence is low in this materializing.

As the previous forecaster discussed, precip chances appear low over the next seven days as high pressure builds in this week. A few showers may be possible on Wednesday, but PoPs have been capped below 15 percent at this time. Weak north-northeast low-level flow for several days will help support a gradual cooling trend this week with highs ranging from the upper 60s to mid 70s for most areas heading into the weekend -- which is close to average for late May. Weak/calm winds at night will allow overnight temperatures to dip into the 40s most nights, and potentially even the upper 30s for localized low-lying interior areas.
