.DISCUSSION...
Issued at 113 PM EDT Fri May 29 2026

Pattern Synopsis and Forecast:

Northeast push of cooler air tonight into Saturday as high pressure
builds down from the north. The place that will see the coolest
temperatures on Saturday will be across northeast lower Michigan,
due to the cold waters of Lake Huron and closer proximity to the
cooler airmass. High temps in the mid 60s to mid 70s most locations
and so all in all, still a pretty pleasant day. Winds start out a
little breezy but decrease through the afternoon.

High pressure directly overhead, dry low level humidity, and light
winds will foster efficient radiational cooling Saturday night.
Blended in some MOS guidance to drop temps to some degree. Localized
frost could be possible as a result, especially for the AuSable
River Valley and subsequent notoriously cooler locations. Worth
monitoring.

Otherwise, despite upper low diving across the eastern Great Lakes
and Northeast, high pressure and ridging will dominate northern MI
later this weekend into much of next week. Consequently,
precipitation free weather reigns supreme with temperatures in the
70s and 80s most locations. There will probably be subtle cooling
when that upper low dives southward as winds turn more north to
northeast, but current guidance does not suggest a whole lot.
Heights really begin to build mid to late next week and thus
temperatures soar well into the 80s once more.

Upper low tries to beat down the ridge overhead later next week into
the weekend, with subsequent sfc low pulling moisture northward.
Thus, we begin to introduce precipitation chances again late week.
We`ll see how this plays out in the future, but regardless, an
extended period of sunny, warm, and dry weather is expected through
much of next week.
