Area Forecast Discussion
National Weather Service Omaha/Valley NE
237 PM CST Tue Nov 14 2017

.SHORT TERM...(Tonight through Friday)
Issued at 230 PM CST Tue Nov 14 2017

Temperatures will be the main concern in the short term as fast
and progressive upper flow continues across the nation.

A surface trough extended from the central Dakotas into western
Nebraska at 19Z with a cold front near the U.S. Canada border in
northeast Montana. An upper trough also extended from from south
central Canada into the northern Rockies. Weather was rather
limited at this time across the region with mainly a broad area of
low clouds ahead of the surface trough stretching from Minesota
and Iowa into eastern parts of Nebraska and Kansas.

The low clouds and patchy drizzle and fog will be moving out of
the area later tonight as the cold front moves through the region
and the upper trough amplifies as it moves across the central
plains. Much drier air will follow behind the front on Wednesday
and allow considerable sunshine to fall on most of the area. The
coldest air is expected to remain north and east of the area with
temperatures generally in the 50s on Wednesday. Warmer air will
continue to overspread the region from the west Wednesday night
and Thursday in advance of another strong upper trough approaching
the west coast. Another cold front will move into the area on
Friday with more clouds and a chance of some light precipitation
for parts of the area.

.LONG TERM...(Friday night through Tuesday)
Issued at 230 PM CST Tue Nov 14 2017

Colder air will continue to spread over the area Friday night into
Saturday with skies clearing during the day on Saturday as the
system shifts east of the area. The remainder of the weekend into
early next week looks to be dry with a warming trend as the upper
pattern becomes split with the primary weather systems indicated
to stay east and south of the area.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1119 AM CST Tue Nov 14 2017

Low-level warm and moisture advections are resulting in
widespread IFR to LIFR stratus across eastern NE today. These
processes are also yielding patchy drizzle which will combine with
areas of fog to reduce visibilities. Expect similar conditions to
persist through the afternoon ahead of a cold front which will
move through the area tonight. With the passage of the front,
expect winds to switch to northwest with ceilings and visibilities
becoming VFR.
