Area Forecast Discussion
National Weather Service Wichita KS
332 AM CST Thu Feb 22 2018

.SHORT TERM...(Today through Saturday night)
Issued at 323 AM CST Thu Feb 22 2018

Today:
As expected most of the good lift ends around 1200 UTC, with
mainly freezing drizzle during the morning. Another ripple in the
flow increases lift this afternoon with precipitation likely
making one more uptick before ending this evening. Thermal
profiles remain challenging, with temperatures aloft continuing to
warm, albeit slowly. Appears area roughly along/west of the
turnpike will remain cold enough for freezing rain/freezing
drizzle well into the afternoon. Will extend advisory through 6 pm
for those areas. While additional accumulations will be light,
given ongoing conditions, the adverse travel threat will persist.

Tonight-Friday:
Precipitation finally ends early this evening but low level
moisture lingers. Expect extensive clouds throughout the night,
with possible exception of extreme western fringe of forecast
area. Surface flow is weak, but there is some potential for fog,
locally dense, where weak south flow develops during the night. At
this point, models suggest flow would be mostly light and
variable. Temperatures should finally warm above freezing areawide
on Friday although there still may be fairly extensive cloud
cover.

Friday night-Saturday:

All models suggest saturated boundary layer with upslope flow.
Anticipate fog (probably dense) and drizzle likely outside of
rain areas. Temperatures will be cold enough in central KS to
support freezing drizzle and freezing rain when precipitation
develops around midnight. Temperatures however will warm and
expect this area to switch light rain by mid morning Saturday.
Rain likely across southeast KS during this period with a couple
storms possible Saturday morning. With the passage of the much
stronger shortwave, precipitation will finally end by Saturday
evening.


.LONG TERM...(Sunday through Wednesday)
Issued at 323 AM CST Thu Feb 22 2018

Forecast relatively unchanged from initialization grids. No
precipitation is forecast until Tuesday, but differences between
GFS/ECMWF with location western longwave/closed low are
significant. Data availability issues likely have impacted
initialization grids. It seems probable that precipitation will
hold off until at least Tuesday evening, and temperatures on
Monday and Tuesday could be warmer than currently forecast.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1112 PM CST Wed Feb 21 2018

Periodic bouts of a light wintry mix will persist through much of
the night across central and south central KS while freezing
drizzle and light freezing rain eventually develop across portions
of southeast KS during the early morning hours. The mixed
precipitation is expected to slowly transition to all freezing
drizzle and/or light freezing rain as we move through the
overnight hours. This will lead to widespread IFR and LIFR
through the morning hours with some improvement during the mid to
late afternoon hours as temperatures are forecast to rise above
freezing across much of southern KS. Low clouds and reduced flight
categories may rapidly return during the early evening on Fri as
light southeast winds return and residual moisture lingers in the
pbl.

.FIRE WEATHER...
Issued at 323 AM CST Thu Feb 22 2018

Fire weather:

There are no indications of serious fire weather threats through
Saturday, however warmer temperatures and increasing winds on
Monday and Tuesday suggest an increase in fire danger. -Howerton
