Area Forecast Discussion
National Weather Service Hastings NE
1200 AM CST Fri Feb 24 2017

.UPDATE...
Issued at 919 PM CST Thu Feb 23 2017

Went ahead and adjusted pops through the overnight hours as the
heavier band of precip and thunderstorms that affected the
southeastern quadrant of the forecast area this evening continues
to exit the region. Expect generally light snow and gusty
northerly winds to continue mainly north of interstate 80
overnight...eventually sagging south towards the NE/KS state line
during the early morning hours tomorrow. While some generally
smaller pops were kept across the entire area overnight...the best
chance for additional accumulating snowfall overnight appears to
be primarily north of the interstate. Also adjusted low
temperatures down a couple of degrees from previous forecast.

.SHORT TERM...(This evening through Friday)
Issued at 321 PM CST Thu Feb 23 2017

Radar has had some increasing returns this afternoon, but so far
there has been little to no surface reports of precipitation this
afternoon. Satellite and observations have low stratus over much of
the forecast area this afternoon, the only area that has had some
sunshine is the far southeast and even there the clouds have been
moving into the area. This has held temperatures from reaching their
full potential this afternoon.

An upper level low is still moving through the central high plains
this afternoon and will move eastward toward the Great Lakes by
Friday evening. There are not many changes to the main forecast for
this afternoon and evening. With the temperatures a little cooler
this afternoon, there may be a bit earlier change from rain to snow
as colder air moves into the area this evening.

There is still a chance for some thunderstorms across the area this
afternoon and evening. With the clearing line just at the far
southern part of the forecast area this afternoon, there has been a
few showers that developed just in the clear air and expect that the
stronger storms would be further to the south where there is more
heating. There could still be an elevated thunderstorm to the north
of that area and have kept isolated thunderstorms into south central
Nebraska for a few hours this afternoon and evening.

The rain will continue to change to snow this evening and overnight
and with northwest winds picking up, there will be some blowing snow
around. The snow will gradually come to an end from southwest to
northeast during the day on Friday and the wind will continue to
bring some blowing snow that will gradually decrease during the
afternoon.

.LONG TERM...(Friday night through Thursday)
Issued at 321 PM CST Thu Feb 23 2017

There could be a little blowing snow during the evening Friday and
the wind will decrease during the evening hours.

A cold surface high pressure will settle into the area Friday night
and move to the east on Saturday and temperatures will be pretty
cold Friday night with some clearing, light winds and the snow.
Saturday will bring temperatures that are a little warmer, but still
cooler than normal.

Saturday night through Thursday will have generally zonal flow with
some upper level waves that move through the area. There will be a
few periods with some light precipitation, but they have been on and
off again and only cover portions of the area. Temperatures will be
on a warming trend with readings near or a little above normal.

Tough call for vis as this is dependent on snowfall. Ceiling may
teeter between MVFR and IFR. Could get som short term freezing
drizzle for the first few hours as well.
