Area Forecast Discussion
National Weather Service Omaha/Valley NE
323 PM CDT Thu Oct 20 2016

.SHORT TERM...(tonight through Sunday)
Issued at 322 PM CDT Thu Oct 20 2016

Latest water vapor imagery loop shows an upper trough axis just
to our east with a weak upstream trough axis sliding southeast
from the Dakotas. Otherwise, cool surface high pressure continues
to slide southeast across the region this afternoon along with an
area of MVFR clouds. Expect this area of high pressure to be
centered over the CWA through the evening with light return flow
increasing by early Friday morning. Clearing skies and calm winds
overnight should allow temperatures to fall to around or just
below freezing in most areas. Frost/freeze headlines are done
across the entire CWA so there will be no mention in the gridded

Otherwise, very quiet conditions are expected over the next
several days with temperatures at or close to normal for this time
of the year.

.LONG TERM...(Sunday night through Thursday)
Issued at 322 PM CDT Thu Oct 20 2016

While temperatures will continue near normal through next
work/school week, we will see an upper level disturbances roll
through the area providing enough support to increase chances for
precipitation. This chance comes early Tuesday morning into
Wednesday as a potent shortwave trough moves east across the area.
Timing issues have yet to be resolved with ECMWF a bit slower than
the GFS. An increase in instability could bring some mention of
thunder as well.


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1235 PM CDT Thu Oct 20 2016

High pressure will settle over the region through 06z then move
east thereafter with southerly winds returning on the backside of
the high. A period of MVFR cigs likely at KOFK through 00z as
secondary short wave trough over the eastern Dakotas shifts east
into the Upper Midwest during that time. VFR cigs expected at both
KOMA and KLNK into the evening before dissipating with transition
of Dakotas trough to the east.
