- Warm and Dry Weather Ahead
Latest Satellite has a band of moisture moving through southern
Lower Michigan. However the atmosphere has dried out that anything
moving in is being evaporated. That is a taste of the things to
come. Models remain in agreement as high pressure settles over the
central Midwest and a large negatively tilted trough sits across
Hudson Bay, extending into Newfoundland. High pressure will build
through the first half of the week as warm air advection moves
into the region and the ridge builds well into central Canada. The
High pressure will persist through the middle of the week as the
high pressure positively tilts eastward. This should be due to an
upper level low moving southward along the Western Coast. The
ridge will also be influenced by tropical depression nine and
Hurricane Humberto. It remains to be seen what interactions will
transpire between this, but the latest trends show Humberto moving
northward before heading out to sea. This would seem likely due
to the movement of the ridge and the advancement of the upper
level low along the west coast that might track into the
intermountain west late int the week. All this to say, that
Michigan will remain warm and dry with Max temps 10 to 15 degrees
above normal and lows around to just above normal. So expect highs
in the upper 70s to low 80s with lows in the upper 40s to low
50s.
