.SHORT TERM...(Today and tonight)
Issued at 329 AM CDT Thu Sep 20 2018

An upper level trough of low pressure will swing east from the
Rockies and cross the Central and Northern Plains today. The main
cold front currently extends from near Norfolk in northeast Nebraska
to McCook in southwest Nebraska. The front will continue to move
very slowly eastward today and become the focus for a line of
thunderstorms across eastern into south central Nebraska during the
mid to late afternoon hours. A secondary cold front will push
southeast into northwest Nebraska early this afternoon, and then
extend from north central through southwest Nebraska late this
afternoon. Between these two features, the upper trough axis will
swing through western and north central Nebraska through the day,
and short term Hi-Res models have been consistent in showing a band
of showers and isolated thunderstorms associated with it. In
addition, the HRRR and RAP develop a narrow ribbon of instability on
the back side of the showers, which could lead to at least isolated
thunderstorm development late this afternoon and evening across
southwest Nebraska along the secondary cold front.

Skies will clear later tonight as mid level subsidence spreads
across the region on the backside of the upper trough. Surface high
pressure will build in from the northwest, and as drier air filters
in, a chilly night with lows near 40 are expected across portions of
northwest Nebraska. Elsewhere expect mid 40s to lower 50s.

.LONG TERM...(Friday through Wednesday)
Issued at 329 AM CDT Thu Sep 20 2018

During the weekend, subtle upper level ridging will translate east
to west across the central portions of the country. This will bring
sunny skies and warming temperatures. South winds will increase
Saturday on the backside of surface high pressure, with highs
ranging from the lower 70s across eastern portions of north central
Nebraska to near 80F across the Panhandle. A nose of warmer air will
spread east across the area Sunday, with H850mb temperatures over
20C across western Nebraska. Highs will be warm as a result, with
mid 80s possible across western Nebraska and upper 70s elsewhere.

Next week looks like a typical fall pattern, with a large upper
level low becoming centered near Hudson Bay. Broad northwest flow
aloft will develop across a large part of the central and western
U.S. as a result, with several cold frontal passages and weak
disturbances bringing the chance for a few showers. Temperatures
will average below normal for much of the week as the pattern change
takes hold.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1145 AM CDT Thu Sep 20 2018

Stratus covers much of the area with ceilings generally ranging
from LIFR to IFR (lowest across northern NEB), except for VFR
conditions in extreme southwest NEB to far northwest KS. Latest
radar display shows a swath of showers across western NEB that
will continue to shift east rest of today. There is some concern
for additional shower and storm development late this afternoon
and evening across southwest NEB and the Sandhills, however,
confidence is low thus not included in the KLBF TAF. Otherwise,
ceilings will gradually improve from southwest to north central
NEB today with decreasing sky cover late today to mid evening.
