Projections of dry conditions suggest warm days–but comparatively cool nights for the holiday. Daily lake breezes–i.e. Cool easterly winds off Lake Michigan across area beaches and in lakeside locations—are a part of the predicted pattern.
Also indicated is the likelihood of below normal 15 day precip over the Midwest even though scattered showers and possible t-storms may occur the back half of next week.
The development of an upper air blocking pattern—what’s known as a “REX BLOCK” or a “HIGH OVER LOW” block aloft–is also front and center as it has been for days in projections of U.S. weather through next week.
The term “REX BLOCK” comes from the meteorologist who first highlighted its existence–Dr. Daniel Rex— first called attention to the pattern. READ MORE on REX BLOCKS here:
