Area Forecast Discussion
National Weather Service Wichita KS
545 AM CST Sun Dec 25 2016

.SHORT TERM...(Today through Tuesday night)
Issued at 322 AM CST Sun Dec 25 2016

Today:
Early this morning scattered light showers developed just north of
a warm front that is draped across Northern OK. Fog is dissipating
across Southeast KS but across most of Central & South-Central KS
widespread fog is still reducing visibilities to 1/2 mile or less.

Today remains by far the most active period of the forecast. A deep
negatively-tilted upper-deck trof that has been discussed for about
a week is still expected to undergo rapid cyclogenesis as it surges
northeast from AZ & NM to the Nebraska/SD border. With an equally
intense surface cyclone situated over Eastern CO, the lower-deck
southwest flow will increase considerably to not only scour the fog
but enable richer moisture to continue surging further into the
Central Plains. Instability is lacking but the deep-layer shear is
STRONG. As the vicious cyclone crosses the Nebraska/SD border this
afternoon, a Pacific cold front will surge east/southeast into KS.
A line of thunderstorms will erupt along the front and with the
deep, very strong shear becoming almost unidirectional, severe
thunderstorms are likely along the front with damaging winds by far
the greatest threat. With the rapid eastward surging front, the
thunderstorms should vacate Southeast KS early this evening. The
strong lower deck moisture advection should offset the strong
southwest winds to prevent the grassland fire danger from venturing
into "Extreme Country". The strong, south-southwest winds have
prompted a Wind Advisory for Central & South-Central KS that'll be
in effect from 9 AM until 5 PM. Record highs are likely in most
areas. The record highs appear at the end of this discussion.

Mon-Tue Night:
Quiet weather slated for all areas as a surface high moves east
into the Great Plains. A 2nd, compact upper-deck shortwave surges
east across KS on Mon but with moisture greatly lacking anticipate
only an increase higher-level cloudiness.

.LONG TERM...(Wednesday through Saturday)
Issued at 322 AM CST Sun Dec 25 2016

Wed-Fri Night:
The remainder of the work-week will be quiet as the Great Plains
will be under a strong W-NW upper-deck regime that'll keep the
neighborhood in a predominantly dry environment.

Next Weekend:
The next chance for any precipitation may arrive on Sat when a
deep upper-deck low should eject a "lead" short wave east
northeast across the Southern Plains. This would of course induce
lower-deck cyclogenesis over the Western Plains that would inject
increasing moisture northeast into KS. For now have assigned a
light rain/light snow mixture to Southeast KS.

.AVIATION...(For the 12Z TAFS through 12Z Monday morning)
Issued at 545 AM CST Sun Dec 25 2016

IFR/LIFR cigs and vsbys will gradually improve later this morning,
though only into the MVFR category within an unseasonably warm
and moist airmass. South winds will increase markedly in advance
of a potent storm system. Scattered to numerous showers will occur
ahead of the associated surface dry-line/cold front, which will
sweep east across the area this afternoon. A line of strong to
marginally severe convection is expected along this front. Even
away from any convection south winds will become quite strong
today, in the wake of the front as well, as deep mixing will
occur in the drier airmass after the frontal passage. VFR
conditions are expected behind the front this evening into tonight
with winds gradually diminishing.
