Area Forecast Discussion
National Weather Service Omaha/Valley NE
302 AM CST Fri Dec 7 2018

.SHORT TERM...(Today through Monday)
Issued at 258 AM CST Fri Dec 7 2018

High pressure remained over the region through the night, with 
northwesterly flow aloft.  Light winds allowed frigid temperatures 
to maintain their grasp on the forecast area, especially where cloud
cover diminished. By 2 am temperatures had dipped into the low 
20s in areas blanketed by clouds. Meanwhile, radiational cooling 
was maximized over areas with snow cover and clear skies. This 
occurred in parts of southwest Iowa and southeast Nebraska, where 
the temperatures dropped into the teens and single digits. 

Chilly conditions are expected to continue through the weekend. 
Temperatures will top out in the mid 20s across northeast Nebraska, 
to around 30F in southeast Nebraska and southwest Iowa Friday 
through Sunday. Overnight, lows will dip into the teens and single 
digits. Climatologically, these temperatures are close to 10 degrees 
below normal for this time of year.  

Generally, quiet weather is expected through Sunday.  However, given 
the lingering high pressure at the surface in addition to light 
winds, there is some potential for patchy freezing fog late Friday 
night into Saturday morning.  An upper low will meander through the 
Central Plains Sunday through Monday morning.  Dry air should keep 
it from producing more than a flurry, otherwise, it will bring 
another reinforcing boost of cold air. 

.LONG TERM...(Monday night through Thursday) 
Issued at 258 AM CST Fri Dec 7 2018

Thankfully, bitterly cold temperatures won't last forever. A ridge 
will build into the nation's midsection behind the departing low 
Monday night and Tuesday, warming high temperatures back into the 
mid to upper 30s Tuesday through Thursday.  A series of shortwaves 
could bring a glancing blow of light precipitation to the forecast 
area Wednesday and Thursday.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1125 PM CST Thu Dec 6 2018

Weak low-level warm advection is maintaining a band of low VFR
ceilings (FL032-035) over much of western IA and far eastern NE as
of 11 PM. Latest model guidance suggests that cloud shield may
drift slowly northeast overnight into Friday morning with a few
flurries possible. At the same time, a patch of mid-level clouds
(FL090) will overspread northeast NE. Expect winds to remain light
from the south into Friday morning before veering to southwest and
strengthening by afternoon. Patchy low VFR ceilings (FL035) could
linger Friday afternoon into evening ahead of a weak front moving
into the area from the northwest.
