Complex weather system will be moving into the area today with a
variety of weather to deal with before changing to snow tonight
into Friday.

Winter storm warning will spread across the north half of the area
today into Friday morning with a winter weather advisory south of
that area into the Omaha and Lincoln areas for Friday and Friday
night. Latest model run has pushed axis of heavy snow a bit
further south with 6 to 10 inches possible for the north half of
the area. Gusty north to northwest winds will compound travel
conditions during this event with considerable blowing and
drifting snow. Rain will be changing to snow in the far north
today with rain and a few thunderstorms this afternoon in the
south with the chance of thunderstorms going into the evening.

Rain will be changing to snow in the south Friday morning and
continue for the afternoon before diminishing Friday evening with

decreasing southward.

Colder temperatures then into Saturday before warming trend
returns for Sunday into early next week.

.LONG TERM...(Saturday night through Wednesday)
Issued at 355 AM CST Thu Feb 23 2017

.AVIATION...(For the 12Z TAFS through 12Z Friday morning)
Issued at 613 AM CST Thu Feb 23 2017

IFR cigs pushed south across all of eastern Nebraska TAF sites
this morning. Expect KOFK to remain in IFR category through the
day, while cigs will likely improve to MVFR at KOMA and KLNK by
18Z. Rain is expected to overspread all TAF sites during the
afternoon. A few thunderstorms are possible at KLNK and KOMA
between 21Z and 06Z, but these should be isolated and thus have
not mentioned them in TAFs at this time.

Rain will change to snow at KOFK between 00Z and 06Z, and will
become heavy at times with attendant LIFR or VLIFR cigs/vsbys
through 12Z. The rain/snow line is forecast to progress south
toward KLNK and KOMA, with a possible change to snow at those
sites before 12Z. However the more drastic deterioration in
cigs/vsbys are expected after the end of this TAF period.
