Area Forecast Discussion
National Weather Service Hastings NE
1120 AM CST Wed Jan 17 2018

.SHORT TERM...(Today and tonight)
Issued at 357 AM CST Wed Jan 17 2018

Temperatures have moderated a few degrees overnight despite clear winds have shifted around to the south. Expect light
southerly winds and mostly clear skies to continue throughout the
day...allowing afternoon temperatures to climb to near seasonal
norms. Due to the presence of at least some light snow cover
across the majority of the local forecast area...opted to stick to
the cooler side of guidance...but would not be surprised if a few
locations rise warmer than forecast where any remaining snow is
very sparse.

As winds shift more southwest overnight and the airmass continues
to moderate...expect overnight lows to fall to near seasonal
lows...but remain well above the frigid lows we have seen of late.

.LONG TERM...(Thursday through Tuesday)
Issued at 357 AM CST Wed Jan 17 2018

High pressure aloft will be in control of the local pattern to
start the extended periods. These increased heights along with
mainly clear skies and a generally west southwesterly flow...will
result in warming temperatures across the region through the end
of the week. As snow cover dissipates...there will be even less
resistance to the modifying airmass...and current forecast highs
in the mid 50s for Friday may actually be a bit too conservative
as some guidance pushes high temperatures across the tri-cities
closer to 60.

By Saturday...expect clouds to begin to filter in across the local
area as an upper level low pressure system makes its way onshore
across central California. As the associated cold front shifts
winds to a more northerly direction Saturday...expect temperatures
to drop back down into the 40s...but still remain on the mild side
for mid-January. At that point the focus will shift to the
deepening low to our southwest which is forecast to emerge into
the plains on Sunday. With model solutions trending a bit
slower...the timing of this system now appears more focused for
the daytime hours Sunday as it swings across the region. While
there is still way too much uncertainty to predict snowfall totals
with this system...with the upper low deepening as it comes
across the local does look like we will likely see a
pretty good chance for some accumulating snowfall along with at
least breezy northerly winds Sunday afternoon. This should also
mark a return to more normal temperatures across the local area
through at least the middle of next week...with minimal...if any
additional chances for precipitation after Sundays main system.


.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Thursday)

Mostly clear skies will be the main story through the period. The
surface high is to the southeast and winds will be mainly from the
