Area Forecast Discussion
National Weather Service Omaha/Valley NE
1241 PM CDT WED SEP 28 2016

.SHORT TERM...(today through Friday)
Issued at 320 AM CDT WED SEP 28 2016

Quiet weather conditions will continue today with noticeably
cooler high temperatures.

A large upper level low continues to drift southeast across the
southern Great Lakes region with a strong vort lobe rotating
around the back side of the low. This has allowed a cold front to
push into the Central Plains and fairly strong 850mb cold air
advection will continue to take place today with 850mb temps
falling about 10C in 24 hours. Highs today will range from the
lower 60s in our western Iowa counties to the mid to upper 60s in
our Nebraska counties. The western edge of an extensive cloud
deck currently extends across the eastern Dakotas and into
central Iowa and continues to expand west. This could impact
areas along and east of the Missouri River today which would keep
temps a few degrees cooler.

Overnight lows will dip into the lower to mid 40s as a surface
high pressure ridge axis extends through the forecast area into
Thursday. This surface ridge axis will remain over the area into
the early part of the weekend.

.LONG TERM...(Friday night through Tuesday)
Issued at 320 AM CDT WED SEP 28 2016

Quiet weather conditions with mild temperatures will continue
through much of Sunday when return low level flow increases across
the Central Plains ahead of a deepening upper level trough over
the western states. A few showers/thunderstorms are possible late
Sunday night provided enough moisture return in a strong warm air
advection regime. Otherwise, low level flow will increase early
next week in advance of the approaching upper level trough which
will eventually push a very strong cold front into the region mid-
late next week.


Issued at 1230 PM CDT WED SEP 28 2016

Weak high pressure ridge will be over the area through the
forecast period. Low clouds with ceilings of 2000 feet over
western Iowa are not expected to reach KOMA. By this evening,
skies are expected to become clear at KOFK, KOMA, and KLNK after
04Z with light winds.
