The second upper level system to move across the area in as many
days will bring another round of showers to the area later today
through tonight. Some mainly elevated instability will bring a
slight chance for storms mostly south of highway 30. Severe storms
are not expected given weak dynamics and very limited surface based

should be around a quarter of an inch or less. Mild weather will
persist with highs today and Tuesday in the 50s and 60s.


.LONG TERM...(Tuesday night through Sunday)
Issued at 438 AM EDT Mon Mar 27 2017

Cool air will spread across the area Tuesday night behind a cold
front as a large high pressure area builds south out of Canada.
Lows Tuesday and Wednesday nights will dip into the 30s. The GFS
has moderated lows from earlier runs, with lows in the 30s. Kept
temperatures above freezing except for Hillsdale county with lows
of 32 degrees both nights. Given thermal profiles, the
precipitation at the onset of the next system appears early
Thursday to be all rain. Some model soundings are close to
freezing rain with a very large warm layer; however, feel there
will not be any weather impacts. Rain should end by the weekend
with highs climbing back to around 60 by Sunday.
