Area Forecast Discussion

...Updated Aviation Discussion...

.SHORT TERM...(Today through Monday night)
Issued at 314 AM CST Fri Jan 19 2018

Persistent southerly flow along with increasing atmospheric
thickness in response to deep shortwave troughing approaching from
the west will support continued above normal temperatures mostly
in the 50s and 60s through Sunday. South winds will be rather
breezy and gusty, especially today and Sunday. Increasing low-
level moisture will support increasing clouds tonight through
Saturday, although suspect moisture and lift will not be deep
enough for drizzle production until possibly Saturday night/early
Sunday.

Attention then turns to potent neutral to slightly negatively
tilted shortwave trough moving across the region Sunday-Sunday
night. Per the latest operational model runs and associated
ensembles, which are in fairly good agreement, thinking the track
of this system will unfortunately be unfavorable for widespread
meaningful precipitation across much of central, south-central and
southeast Kansas. Consequently, expecting relatively low impact
from this system across Wichita`s forecast area.

Given the presence of a stout mid-level dry slot, precipitation
type will mostly be in the drizzle variety beginning Saturday
night, which may be in the form of patchy very light freezing
drizzle across central KS where temperatures will be below
freezing. The upper system and associated surface wave will eject
northeast across the area Sunday and Sunday night, with a tight
thermal gradient existing across the area (30s western KS, 60s
southeast KS). Given the system`s track and associated lift,
moisture, instability and thermal profile, the greatest potential
for plowable snow will be northwest of the forecast area,
stretching from northwest KS and far northern KS, and up through
NE. Far northern/northwest portions of Wichita`s forecast area
(Barton-Russell-Lincoln counties) will likely see less than one
inch Sunday evening-night given current model and ensemble trends.

Meanwhile, modest Gulf moisture return, steepening lapse rates
and weak instability ahead of the approaching shortwave and
associated frontal zone may support a handful of showers and
perhaps even a few thunderstorms Sunday afternoon-evening across
far eastern KS, although suspect better chances will remain
further east/southeast across Missouri and Arkansas. All
precipitation will end Monday, with strong northwest winds and
cooler temperatures in the 40s.

.LONG TERM...(Tuesday through Friday)
Issued at 314 AM CST Fri Jan 19 2018

Model and ensemble consensus supports a return to quiet weather
through about Thursday. With the main polar/arctic jet remaining
north of the region, not expecting any major cool downs, with 40s-
50s expected next week. While specifics remain unclear this far
out, operational models and ensembles hint at another deepening
western and central CONUS trough by next Friday-Saturday, which
could bring another round of precipitation to the region. Stay
tuned for later forecasts.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1116 AM CST Fri Jan 19 2018

Through the remainder of today, expect southerly winds and VFR
conditions at all area airports. During the early morning hours of
Saturday, a rapid increase in low-level moisture is expected in
southeast Kansas, which should drop cloud ceilings into the IFR
and eventually LIFR category at CNU. MVFR ceilings are also
likely to spread far enough westward to affect ICT and potentially
HUT, though exactly how far west the low cigs push is the main
uncertainty in the forecast at this point. Central Kansas
airports (RSL, GBD, and SLN) should maintain VFR cigs through the
18Z TAF period.

.FIRE WEATHER...
Issued at 314 AM CST Fri Jan 19 2018

Breezy south winds will support marginal very high grassland fire
danger today. If current expectations verify, very high to low-
end extreme grassland fire danger could impact primarily south-
central KS Sunday afternoon, as strong/gusty south to southwest
winds couples with drying low-levels and above normal
temperatures. Very high grassland fire danger is also possible
Monday due to strong/gusty northwest winds in back of this system,
despite cooler temperatures.
