.SHORT TERM...(This Evening through Tuesday)
Issued at 218 PM EDT Mon Mar 30 2020

Breezy northwest winds diminish tonight as the surface pressure
gradient relaxes in response to surface ridging overspreading the
area. Clouds will also be on the rise during the overnight hours
given continued easterly flow aloft. Conditions remain cloudy on
Tuesday with a few localized sprinkles possible as a 600-700mb
Fgen band drops southwards from central Lower Michigan over the
course of the day. Highs remain on the cool side for late
March/early April; lower to mid 40s.

.LONG TERM...(Tuesday Night through Monday)
Issued at 218 PM EDT Mon Mar 30 2020

Long term portion of the forecast shows fairly benign weather
through the work week with highs near or slightly below average for
early April. Next chance for widespread rainfall continues to be
tied to a shortwave which breaking from a stalled low over the
Pacific NW/British Columbia. This shortwave is shown breaking
away and making eastward progression around Wednesday before
reaching the area late in the week. Models continue to have
slight differences in timing, but the ongoing trend of slowing the
system seems to be winning out. The result is the impacts of this
shortwave would likely not be felt until late Friday, or more
likely Saturday as advertised in the ECMWF over the past several
days. When this shortwave approaches the area, it should send a
cold font across the forecast area with preceding showers.
