Area Forecast Discussion
National Weather Service Omaha/Valley NE
515 PM CST Sun Dec 10 2017

.SHORT TERM...(Tonight through Wednesday)
Issued at 320 PM CST Sun Dec 10 2017

Large scale flow over the CONUS will be stagnant over the next
several days with mean ridging west/trof east. However, a series of
of shortwaves dropping out of Canada into the northern/central
Plains will be the only one to bring a threat for precip to the
region Monday afternoon.

Cold air advection spills into the region tonight/Monday as a
clipper-type surface low digs southward through the upper midwest
into the mid MS valley. Models in agreement that is where the bulk
of precip activity will occur. It does appear though a sliver of the
northern CWA may see a drop or two Monday afternoon. The next
shortwave moving through on Wednesday drags another cold front with
it. However, the models are favoring areas well to the east of the
CWA for precip activity.

Cold conditions Monday-Thursday morning with highs topping out
generally in the low/mid 40s...overnight lows in the 20s.

.LONG TERM...(Wednesday night through Sunday)
Issued at 320 PM CST Sun Dec 10 2017

Models prog a bit more progressing pattern heading into next
weekend. However, only a small chance for seeing any precip on
Saturday morning. Well above normal temps expected in the extended
periods with highs generally in the mid/upper 40s and lows in the
mid 20s.


.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 515 PM CST Sun Dec 10 2017

Expect VFR conditions overnight with some variable mid and high
level clouds. Lower clouds (BASES 3000-5000 FEET) should move
into the area from the north Monday morning. Winds will also be
increasing, with some gusts over 30 knots. Spotty light rain or
light snow showers are possible, mainly at KOFK and mainly in the
afternoon. Will not include a mention at KOFK, but not at KOMA or
