.DISCUSSION...High pressure settled over Lake Superior keeps skies
mostly sunny today and tonight before an incoming low from
the Northern Plains begins bringing mid to upper level cloud cover
over Upper Michigan Wednesday. That being said, expect conditions
to be fairly similar to what we saw yesterday, albeit with
temperatures being a little cooler today and min RHs a little
lower and around 35 percent in the interior east. A more rainy pattern
looks to come over us Thursday as the low pressure finally arrives.
