555 AM CST WED FEB 10 2016

.SHORT TERM:  (Through Late This Afternoon)
Issued at 341 AM CST Wed Feb 10 2016

...Light Snow This Afternoon and Evening...

A fast moving clipper system will move from North Dakota to central
Oklahoma today. A fairly narrow band of light snow accumulation is
expected to occur from central North Dakota to southwest Illinois
over the next 24 hours in response to an area of frontogenesis that
accompanies the system. Limited moisture, quick moving nature of the
system and weakening frontogenesis will locally keep accumulation
under advisory criteria. Have increased PoPs to categorical, but
retained snow accumulation forecast of around an inch.

Next shortwave forecast to dive southeast into the Midwest on
Thursday night and Friday, but majority of snow from this feature
looks to remain to the northeast of our CWA. Otherwise, it looks
cold for the remainder of the week with the prospect of a advisory
level warm advection snow event this weekend, but a lot can change
between now and then, so stay tuned.
