low level clouds were spreading west from far southeast lower
michigan and northwest ohio into northern indiana and far
southwest lower michigan. the intrusion of these clouds will
halt the development of radiational fog that was trying to
develop where skies where skies were clear. morning cloud cover
will limit insolation and subsequently limit high temperatures
to the 60s over northwest ohio and far southern lower michigan.
temperatures will become very warm monday as an upper level ridge
builds north of the ohio river. in addition to the warm temperatures,
precipitable water values will soar well above 1.0 inch with
gfs values exceeding 1.5" along the pwat axis that will translate
east across the forecast area late monday into early monday night.
in addition to the flood and possibly flash flood potential, favorable
bufkit bulk shear profiles will bring a risk for damaging winds and
isolated tornados west of highway 31.
lingering showers will end early wednesday followed by dry conditions
with highs mostly in the 50s the rest of the week. given the likelihood
of the growing season becoming more advanced, frost is likely to
be impactful as temperatures across the locally colder spots to dip
well down into the 30s.
