A cold front brings a band of rain showers first into the Tri Cities
area early in the morning which then moves to the south and east
across the rest of SE Michigan during the day. Broken coverage of
showers produces rainfall totals generally less than 0.2 inch as the
band weakens while moving through the region and then exits by late
afternoon. A second round of showers develops mainly after midnight
Thursday night and lasts through Friday morning. This system brings
higher rainfall amounts over a wider area averaging about 0.5 inch
in a 6 to 12 hour time window. There is a chance for localized
totals near 1 inch where embedded thunderstorms occur before this
pattern also exits southward and eastward Friday afternoon. Flooding
potential remains low with this event, although the new rainfall
could slightly delay drainage from river and stream systems after
the heavy rain that occurred last weekend.
