Area forecast discussion 
National Weather Service Omaha/valley NE 
612 am CST Friday Nov 27 2015 

Short term...(today through sunday) 
issued at 351 am CST Friday Nov 27 2015 

Winter weather system is exiting the area...with wintry temperatures 
left behind. Subjective 00z upper air analysis indicates elongated 
upper-level trough extending from near Hudson Bay through ND/Montana and 
toward NV/CA. Southwesterly upper-level flow ahead of the trough 
extended across the plains...with 165kt jet streak north of the 
Great Lakes and 130kt jet streak in the southwest US embedded within 
a large swath of 100kt+ jet winds. At 850mb...tight temperature 
gradient extended from the Great Lakes across Iowa into eastern 
Kansas...with 9.8c at ktop and -4.5 degrees at koma. Moisture axis 
extended ahead of the front from the Southern Plains toward the 
southern Great Lakes. 

Main forecast concern is return of precipitation...likely in another 
messy wintry mix...from Saturday into early next week. May see 
light precipitation linger near the Kansas-Nebraska border this 
morning...though most measurable precipitation should remain 
south/southeast of the County Warning Area. Otherwise...cloudy skies south to 
partly cloudy north...and continued north winds and cold air 
advection...will make quite a blustery day for today. Low-level 
moistening is prognosticated into Saturday morning...but with a dry middle- 
level layer above it...concern is that there may be a freezing 
drizzle potential. Kept measurable probability of precipitation in for collaboration 
sake...but think chances are actually better that it would be more 
of a freezing drizzle Saturday/Saturday night and perhaps even into 
Sunday. Later Sunday and Sunday night...profiles finally 
saturate...and wintry mix then depends on the temperature profile 
rather than saturation. May still be a mix until later on 
Monday...with precipitation eventually changing to snow. Confidence 
in precipitation type and timing is quite low...especially for being 
within 3 days. 

Have bumped up min temperatures through Monday...with potential for 
lingering clouds and low-level moisture at night along with a lack 
of a snowpack. With maximum temperatures in the 30s...should see little 
diurnal temperature movement. 

Long term...(sunday night through thursday) 
issued at 351 am CST Friday Nov 27 2015 

In wake of whatever wintry mess falls through Monday night...the 
rest of the week looks drier. Cannot rule out some lingering very 
light snow/precipitation on Tuesday in the northern/northeastern 
County Warning Area...but the bulk of it will be off to the east...and dry weather 
will follow for the rest of the work week. With westerly 850mb winds 
and increasing 500mb heights...temperatures should moderate slowly 
through the week. 


Aviation...(12z tafs for kofk...klnk and koma.) 
Issued at 608 am CST Friday Nov 27 2015 

Variable conditions prevail across eastern Nebraska at the start 
of the period with scattered-broken MVFR ceilings at all three sites through 
18z. VFR ceilings are expected to dominate after 18z as high pressure 
builds into the region.
