Area Forecast Discussion
National Weather Service Hastings NE
249 PM CST Sat Dec 15 2018

.SHORT TERM...(This evening through Sunday)
Issued at 143 PM CST Sat Dec 15 2018

An upper level trough crossing the Dakotas will bring increasing
mid/high level cloud cover overnight...along with a shift in winds
by day break Sunday. In the meantime...expect the increased cloud
cover to help keep overnight temps a degree or two above last
nights readings...with lows overnight expected to range from the
upper teens in the coldest the mid 20s elsewhere.

As the trough tracks east and winds shift to the northwest on
Sunday...expect a modestly cooler airmass to infiltrate the region
with most locations topping out 5 to 7 degrees below this
afternoons readings. That said...this still represents very mild
mid-December weather...with expected high temperatures still
forecast to climb 10 or so degrees above seasonal norms.

.LONG TERM...(Sunday night through Saturday)
Issued at 143 PM CST Sat Dec 15 2018

Continued mild and primarily dry weather is expected to dominate
the central plains through the extended periods with the only
exception being late Wednesday...when a strong trough of low
pressure brings a small chance for some light rainfall primarily
north of interstate 80. That said...this system is lacking deep
moisture...and little more than a few light rain showers or
sprinkles are anticipated. Otherwise...temperatures will remain
mild through the end of the week...fluctuating generally 10 to 15
degrees above normal each afternoon. A slight cool down is
possible next Saturday as a cold front crosses the region...but
even so...this looks to only be a modest change in the underlying
airmass for the time being...with above normal temperatures likely
continuing into next weekend.


.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Sunday)
Issued at 1130 AM CST Sat Dec 15 2018

VFR conditions are expected through the period with passing high
clouds and gusty southerly winds this afternoon diminishing and
become west northwesterly by early Sunday morning in the wake of
passing trough.
