.SHORT TERM...(This Evening through Wednesday)
Issued at 310 PM EST Tue Nov 21 2017

A cold front was over far southwest Lower Michigan into northwest
Indiana this afternoon. A strong upper level system with favorable
upper level jet dynamics were able to overcome a very dry
environment and produce an area of rain in the vicinity of the
front. The best upper level support was north of the Michigan line
where rainfall amounts exceeded a tenth of an inch. Rainfall
amounts mainly under 0.05 inch are expected over Indiana and Ohio
before midnight. Very low inversion heights should prohibit a lake
response of lake effect rain or snow showers. High pressure will
continue to build in Wednesday with decreasing clouds and cold
weather.
