Area Forecast Discussion
National Weather Service Omaha/Valley NE
319 PM CST Tue Dec 12 2017

.SHORT TERM...(Tonight through Friday)
Issued at 319 PM CST Tue Dec 12 2017

Quiet weather tonight with west southwest winds ahead of a strong
cold front that moves into the area on Wednesday as an Alberta
clipper moves out of the northern Plains. This could bring
isolated showers to the NE/SD/IA tri state region in the morning,
but more importantly, will substantially increase northwest winds
by mid morning. Wind gusts could easily reach 45 to 55 mph as the
surge of colder air begins to move in. Thus we issued a wind
advisory for northeast NE and west central IA valid from 9am-4pm.
Locations south of the advisory area may be just below wind
advisory criteria with gusts up to 45 mph, but will let the next
shift decided if the advisory needs to be expanded further south.

Quiet and colder weather again for Wednesday night. Another
Alberta clipper arrives on Thursday, which brings a chance of snow
and rain to the area, with minor accumulations less than 1/2 inch
possible in northeast NE. Precip lingers into Thursday evening,
but ends by midnight. Warming temps expected again for Friday with
west southwestern surface flow.

.LONG TERM...(Friday night through Tuesday)
Issued at 319 PM CST Tue Dec 12 2017

Another Alberta clipper drives a cold front into the area on
Saturday. Still there is not impressively cold air with this next
front, but it will still bring a small chance of rain changing to
snow along/north of I80 by Saturday afternoon/evening. Slightly
cooler but still above normal on Sunday, then moderating temps
well above normal for Monday and Tuesday.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1127 AM CST Tue Dec 12 2017

A ribbon of VFR clouds will continue to push east over KOMA and
KLNK early this afternoon and has already cleared east of KOFK.
Little in the way of aviation concern as it remains VFR.
Otherwise, a cold front will sweep through the area in the early
morning hours providing LLWS to the TAF sites. Gusty northwest
surface winds to 30kts expected for Wednesday morning.


NE...Wind Advisory from 9 AM to 4 PM CST Wednesday for NEZ011-012-

IA...Wind Advisory from 9 AM to 4 PM CST Wednesday for IAZ043-055-056.
