DISCUSSION...

The much ballyhooed upper level blocking pattern remains in place over central North America and will continue to hold off any moisture return over the Great Lakes through the middle of the upcoming week. A thinning of the omega block is forecasted on Monday as deep upper level trough will encroach on Southeast Michigan from the north and east. However, heights will rebound quickly for the middle of the week as the large amplitude ridge nudges eastward and eventually takes on more of a Rex block configuration. To put this ridging event into perspective, the NAEFS data supports a high end to climatological extreme event with, the heights (Tue-Wed) at all of the levels, 1000-850-700-500mb at the 99.5 percentile. It isn't the surface anticyclone or mslp that has been unprecedented its been the depth of the anticyclone that has persisted and encapsulated the western Great Lakes. So, as this ridge finally folds over the region, midlevel temperatures climb significantly resulting in daytime highs some 10 to 15 degrees above normal Thursday through Sunday.

The main weather narrative for Today through Tuesday is extremely comfortable weather with low humidity and highs in the middle to upper 70s. Humidity likely becomes noticeable late Thursday and Friday with dewpoints climbing towards 60 degrees. Uncertainty exists with the next chance for meaningful precipitation chances as there is some timing difference with regards to the reestablishment of zonal flow over the Great Lakes. The latest forecast brings chance Pops into the area late Friday and for next weekend.

MARINE...

Light and variable winds expected today as high pressure settles overhead, ensuring another day of dry weather. A weak cold front then settles across the eastern Great Lakes tonight, reorganizing flow out of the northeast. Gusts may briefly touch 25 knots Monday afternoon over Saginaw Bay where flow aligns with the fetch of the bay, but should hold below 20 knots elsewhere. Extended stretch of dry weather then persists through at least mid-week.
