Area Forecast Discussion
National Weather Service Omaha/Valley NE
628 AM CDT Thu Oct 27 2016

.SHORT TERM...(today through Saturday)
Issued at 330 AM CDT Thu Oct 27 2016

Latest medium range models indicate no significant active weather
to contend with over the next several days...leaving temperature
the main issue. A warming trend begins in earnest today in part to
decent mixing...particularly on the wrn periphery of the CWA where
aftn highs will be pushing into the upper 70s...with upper 60s
over our IA CWA. On Friday...good mixing once again will allow
temps to top out around 80. At this not believe record
highs at KOFK...85//KOMA and KLNK...84// will be in jeopardy.

A cool Canadian air mass invades the central plains then on Saturday
with the leading edge of the bndry moving thru the KOMA metro
sometime toward late aftn. Given this...could see max temp spread
ranging from the mid 60s north to the mid 70s south. However...have
noted that both the GFS20 and SREF are suggesting the nrn CWA could
reach max temps in the mid 70s between 18z-21z.

.LONG TERM...(Saturday night through Wednesday)
Issued at 330 AM CDT Thu Oct 27 2016

No major changes anticipated in the extended periods with dry
conditions continuing thru Tuesday aftn. Pcpn chances return late
Tuesday night thru Thursday in association with the approach of a
potent vort max progged to eject out of the swrn CONUS.


.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 626 AM CDT Thu Oct 27 2016

Areas of LIFR vsbys/cigs will linger at KOFK and KLNK for a few
hours this morning, and could spread into KOMA area as well. Rapid
improvement to VFR is expected between 14Z and 16Z when south
winds increase to about 12kt helping fog to lift. VFR conditions
under scattered high clouds is forecast for the rest of the TAF
period. However, low level wind shear is expected after 06Z at all
