...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL OVER PORTIONS OF
THE NORTHERN UNITED STATES...

Great Lakes Region...
A cold front associated with what had been the highly dynamic
system on Monday will shift westward into the western Great Lakes
region on Tuesday. The front should encounter some lingering
moisture that propagated downstream on Monday but the overall
moisture pattern is getting stretched. The GFS showed precipitable
water values...though...are either side of 1.5 inches on Tuesday
morning from parts of Wisconsin south and eastward. Values that
high tend to be pushing 2 standardized anomalies greater than
climatology for this time of year...so some locally enhanced
rainfall rates are possible.

Northern portion of the Western High Plains...
With the mid/upper low moving little since Monday...continuation of
rainfall at the lower elevations should continue into Tuesday, Only
change from the previous outlook was to minimize the overlap
between the Marginal Risk area and area where snowfall is forecast
by the WPC Winter Weather Desk.
