Area Forecast Discussion
National Weather Service Hastings NE
559 PM CST Mon Dec 11 2017

Issued at 540 PM CST Mon Dec 11 2017

Updated the forecast earlier as we allowed the Red Flag Warning to
expire. Wind speeds should continue to gradually decrease this


.SHORT TERM...(This evening through Tuesday)
Issued at 335 PM CST Mon Dec 11 2017

Clouds have moved into much of the forecast area this afternoon,
with just a band of mostly clear skies between a couple of bands of
clouds. The north to northwest winds have started to subside a
little bit, but are still gusty across the area.

The winds should continue to subside this afternoon, but the
gustiness should continue into the evening hours before slowly
decreasing. The clouds should continue through sunset, but decrease
some during the evening before moving out of the area early Tuesday
morning. Tuesday will be mostly sunny and the west winds will be
around 10 mph.

.LONG TERM...(Tuesday night through Monday)
Issued at 335 PM CST Mon Dec 11 2017

Another cold front moves through the forecast area Tuesday night.
There will be little more than the wind shift during the night
Tuesday night, but on Wednesday the colder air filters into the area
and the winds start to pick up again. Winds will be breezy again and
have raised wind speeds a little. There is also some moisture that
gets pushed into the area and there could be a few more clouds
during the later afternoon and evening. The cooler air starts to
filter in Wednesday night and temperatures are a little cooler on
Thursday. There will be an upper level wave that moves through the
area Thursday. There will be a push of moisture into the area as the
wave moves in and temperatures aloft are cooling. Models have some
light precipitation in the northeast part of the forecast area
during the day on Thursday. Temperatures at 850mb are cold enough,
but the temperatures at the surface warm a little. It could start as
snow in the morning, mix with and change to rain during the day,
then maybe have a little mix in the afternoon before the
precipitation comes to an end.

Thursday night the wave moves out, the low level moisture moves east
and the clouds move out. It will be cool that night before the warm
advection mixes down to the surface. The next cold front will be
moving through the area late Friday night into Saturday morning.
There will be a few more clouds and breezy north winds again but it
should remain dry. Northwest flow will continue Sunday and Monday
with mild temperatures.


.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Tuesday)
Issued at 540 PM CST Mon Dec 11 2017

Trickiest part of the forecast will be ceilings flirting with MVFR
this evening, especially for GRI. Currently VFR, but we could
temporarily go MVFR for short periods of time before VFR
conditions completely take a foothold.
