Area Forecast Discussion
National Weather Service Omaha/Valley NE
1151 AM CST Tue Feb 14 2017

.SHORT TERM...(Today through Thursday)
Issued at 321 AM CST Tue Feb 14 2017

Quiet weather continues through the short term with continued
above normal temperatures.

Northwest flow aloft remains overhead with a strong ridge over
the northwestern US and a trough across much of Ontario. This
trough will send a weak shot of cold air advection skirting into
our area as the trough drops southeast through the Great Lakes
region today. Favorable northwest mixing winds could produce some
gusts this afternoon into the 30 mph range but these should
subside by evening as the surface pressure gradient relaxes with
broad high pressure building overhead.

The above mentioned Great Lakes trough is forecast to push into
the northeastern US by Wednesday allowing the above mentioned upper
ridge to build into the central US. This will push Thursday high
temperatures into the 60s across most of the forecast area.

.LONG TERM...(Thursday night through Monday)
Issued at 321 AM CST Tue Feb 14 2017

By Friday, the upper ridge axis will be centered over the central
US allowing highs to reach into the mid to upper 60s. A weak
shortwave is progged to top the ridge over the Dakotas by Friday
night sending a weak cool front into the area, but primarily just
a wind shift per 00z GFS. Upper flow becomes southwesterly by late
in the weekend as the ridge shifts east and a trough digs across
the western US. This is progged to move northeast into the central
US by late in the weekend. Models continue to show strong/moist
southerly flow coming up from the Gulf producing a period of
showers and possibly isolated thunder ahead of the approaching
trough early next week.


.AVIATION...(18Z TAFS for KOMA...KLNK...KOFK through 18Z Wednesday)
Issued at 1147 AM CST Tue Feb 14 2017

scattered to broken high clouds. Northwest winds 15 to 20kt will
diminish to or below 12kt this evening.
