Area Forecast Discussion
National Weather Service Omaha/Valley NE
505 AM CST Mon Nov 20 2017

.SHORT TERM...(Today through Tuesday)
Issued at 258 AM CST Mon Nov 20 2017

Main forecast challenges center around temperatures and winds with
dry weather forecast for the entire 7-day period.

Weak northwesterly upper-level flow will amplify through the week as
a strong ridge remains anchored over the western U.S. Strong
southwesterly mixing winds should help push temps into the upper 50s
to lower 60s this afternoon with the only caveat being high
clouds. Will need to watch this today as this could knock a couple
degrees off our highs. A quick moving short-wave will drop
through the Northern Plains bringing a cold front into the area
tonight. Strong cold- air advection and gusty winds will create
fairly blustery conditions on Tuesday with highs barely reaching
above the freezing mark in our north. Combined with gusty
northwest winds, apparent temperatures will remain in the teens
across our north through much of the day Tuesday.

.LONG TERM...(Tuesday night through Sunday)
Issued at 258 AM CST Mon Nov 20 2017

Surface high pressure will move overhead by late Tuesday night
allowing lows to bottom out in the mid to upper teens. Warm-air
advection resumes in return flow around the departing high by
Wednesday with increasing warm-air advection through Thanksgiving
and into Friday. A cold front will drop into the area Friday which
should allow temperatures to mix out into the mid to upper 60s
which is just a few degrees below record values in the low 70s.
Mild temperatures will continue into the weekend as upper level
ridging amplifies over the western half of the country.


.AVIATION...(For the 12Z TAFS through 12Z Tuesday morning)
Issued at 505 AM CST Mon Nov 20 2017

Expect VFR conditions through the period. Southwest winds will
increase and become gusty, especially at KOMA and KLNK today.
Winds drop off this evening, then shift to the north/northwest and
increase overnight.
