.SHORT TERM...(This Evening through Wednesday Afternoon)
Issued at 347 PM CST Tue Feb 21 2017

A couple short wave troughs moving over the region along with a
surface cold front dropping south on Wednesday will bring an
increase in clouds along some chances of light rain/sprinkles later
tonight and Wednesday. Made only some small adjustments to pops
through Wednesday afternoon. It will be a mild night across the
region with lows in the mid 30s to the lower 40s. Wednesday will
remain above normal as the caa kicks in. Mid 40s to mid 50s still
are expected across the region as winds become northwest and
increase.

.LONG TERM...(Wednesday Evening through Tuesday)
Issued at 347 PM CST Tue Feb 21 2017

Main issue in the extended continues to be the storm system which
will slide east across the Plains Thursday through Friday. Latest
round of model guidance continues to keep the brunt of the system
south of the area, with the highest snow accums across the southern
third of SD and into northern NE and over IA. Although, this storm
does appear to be far enough north to give southern parts of the CWA
at least some light snow accums. Will continue to monitor model
trends for any northward push. There will be some gusty winds with
this system, so any snow that falls over southern areas may be blown
around and reduce visibility at times.

After that system departs, things look mostly dry through the
weekend, but will be watching some weak shortwave energy dropping
southeast through the region on Sunday. This could bring a batch of
light snow through the area.
