.SHORT TERM...(This evening through Saturday night)
Issued at 240 PM CST Fri Dec 6 2019

Northwest flow aloft will gradually become more westerly by Sunday
ahead of shortwave digging southeastward across the western CONUS.
Dry and very mild weather is expected Saturday after a mostly clear
and calm night tonight. Not seeing a strong signal for fog tonight,
but cannot rule out a few patches in lower lying areas, especially
after the recent and melting snow. Otherwise very mild air will
overspread the region tonight, with H85 temps rising to around 10C
on Saturday. This will boost highs well into the 50s Saturday under
mainly sunny skies. There will be a few high cirrus clouds, but this
should have little impact on temperatures. A mild night expected
Saturday night as light westerly winds though the night will help
keep the boundary layer mixed some.

Sunday will likely be a few degrees cooler than Saturday, as mixing
will be weaker and H85 temps cool a few degrees. In addition there
will be an increase in clouds as the western CONUS shortwave begins
to move into the plains. Still highs in the mid 40s to mid 50s are

.LONG TERM...(Sunday through Friday)
Issued at 240 PM CST Fri Dec 6 2019

The shortwave quickly moves eastward across the region Sunday night
into Monday. A cold front will plunge southward behind surface low
pressure that moves east across the area with the wave. Mid-level
FGEN develops develops across north central Neb. Sunday evening and
persists till around sunrise Monday morning. Sounding profiles
confirm that a period of light snow should result, with snow
accumulating to near 1 inch across Boyd county. Elsewhere generally
1/2 inch or less accumulation is expected. It will be much colder
behind the front Monday into Tuesday as a batch of arctic air moves
southward into the area. Highs will struggle to get out of the teens
across far north central Nebraska both days.

Mild Pacific air works it`s way back into the area by Thursday into
Friday, with highs returning to the mid 30s to mid 40s. Continued
dry through this time as northwest flow aloft dominates.


.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1129 PM CST Fri Dec 6 2019

VFR conditions should prevail the next 24 hours across western
Nebraska. Skies are currently clear to mostly clear throughout
western Nebraska. Some high clouds are currently moving across
Wyoming and Montana to bring a few high clouds to the area for
Saturday. Winds will be light southwest overnight, then increase
to 22015G23KT at KVTN by 20Z Saturday. Patchy fog is possible in
low lying areas late tonight and early Saturday, mainly across
southwest Nebraska. Mesoscale models do not indicate this should
occur, so no mention in the 06Z TAF issuance.
