Area Forecast Discussion
National Weather Service Omaha/Valley NE
1135 PM CST Thu Dec 7 2017

Issued at 924 PM CST Thu Dec 7 2017

Beginning to have my doubts about any snow flurries moving into
the area tonight. Very light flurries across western NE have been
diminishing. Isolated flurries in central SD may hold together
moving toward northeast NE in the next few hours, but latest
highres CAMS show very little reflectivity moving into the
remaining areas overnight and early Friday morning. Thus will
leave a mention in for northeast NE tonight, but pull it from
other locations. Also have adjusted temps a bit, for those favored
locations which dropped quickly right after sunset.


.SHORT TERM...(Tonight through Sunday)
Issued at 320 PM CST Thu Dec 7 2017

Water vapor imagery this afternoon was showing a well defined ridge
situated over the west coast with a deep positive tilt trof
extending from southeast Canada to the southern Plains. At the
surface...high pressure was in control over the western half of the

Going forecast looks in good shape, so no major changes planned.
Models in good agreement that large scale flow will not be too
progressive into and through this weekend with a mean ridge
west/trof east with a series of vort maxes dropping into the
upper/mid MS region. Fortunately, the CWA will not fall under the
influence of any. Will continue mention of possible flurry activity
for later tonight given brief period of subtle upglide.

Otherwise...cold air advection spills into the central Plains with
frontal passage through the Omaha metro sometime toward 12z Friday.
Highs Friday and Saturday will struggle to top out in the mid 30s
north/upper 30s south. Shallow mixing aids with temp rebound on
Sunday with highs in the low 50s east/mid 50s west.

.LONG TERM...(Sunday night through Thursday)
Issued at 320 PM CST Thu Dec 7 2017

NIL significant weather to be concerned with as mean ridging
west/trof east prevails during the extended periods. Given no
significant thermal intrusion seen on the horizon, expect above
normal temps with highs generally in the low/mid 40s and lows in
the mid 20s.


.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1133 PM CST Thu Dec 7 2017

could develop at KOFK 14-17z. Could also be a snow flurry or two
