Area Forecast Discussion
National Weather Service Wichita KS
355 AM CDT THU MAY 26 2016

.SHORT TERM...(Today through Saturday Night)
Issued at 355 AM CDT Thu May 26 2016

Forecast Headline:
Severe thunderstorm potential remains high from late this afternoon
thru tonight with very large hail and tornadoes the greatest
threats.

This Afternoon & Tonight:
During the night a deep upper-deck trof was positioned over AZ. The
upper trof is still expected to push slowly E across the Srn
Rockies today & is still expected to experience cyclogenesis as it
begins to lift very slowly NE from Nrn NM late tonight, with the
upper cyclone reaching the CO/KS border early Fri Morning. As this
character lifts NE sfc cyclongenesis will increase considerably as
the sfc low ventures from NE NM to the TX/OK Panhandles/SE CO/SW KS
region this afternoon. The ultra-high octane moisture streaming N
will team with the greatly increasing deep-layer shear, both speed
& directional, to trigger severe thunderstorms across most of KICT
Country late this afternoon & this evening. Although it won`t be
quite as warm/hot yesterday, the extremely rich moisture would be
more than sufficient to cause extreme destablization. CAPES will
experience an adrenaline rush with SBCAPES & MLCAPES projected to
reach 4,000-5,500 J/KG & primarily 3,500-4,000 J/KG, respectively &
deep-layer bulk shear increasing to 40-60 KTS & an E-W sfc boundary
forming near I-70, there will be supercells that`ll be capable of
very large hail that now is likely to reach around baseball-sized
& tornadoes. Areas at greatest risk for such large hail & tornadoes
would be from Southern Nebraska to nearly all of Central KS. SPC
continues to assign "Enhanced Risk" to these areas but wouldn`t be
surprised to see them up the ante to "Slight Risk". Stay tuned.

This Weekend:
With the overall pattern making very slow ewd progress, more
thunderstorms will fire across the region. Although the projected
instability & deep-layer shear won`t be as impressive, plus the
absence of a lower-deck focusing mechanism, still expect a few
strong-severe thunderstorms to develop Fri Afternoon & Evening
with the convection weakening Fri Night. Scattered thunderstorms
will continue thru the weekend.

.LONG TERM...(Sunday through Wednesday)
Issued at 355 AM CDT Thu May 26 2016

The GFS & ECMWF continue to agree quite well with overall pattern
 with both depicting a weak zonal regime Sunday & Sunday Night. A
2nd upper-deck trof is forecast to move E & like it`s predecessor
it`ll move slowly E & strengthen as it digs across Srn CA. A lead
shortwave will eject NE, likely reaching Wrn OK & Wrn KS Sun
Afternoon. As such, there`ll be several rounds of thunderstorms
from Sun Afternoon thru next Tue.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1124 PM CDT Wed May 25 2016

Main Aviation Hazards: Stratus development overnight into Thursday
morning area-wide. Then thunderstorm chances Thursday
afternoon/evening.

MVFR to IFR stratus should develop over south-central and
southeast Kansas overnight, and central Kansas early in the
morning. This will be in response to a very moist boundary layer
with lowering dewpoint depressions, with the addition of
developing upslope easterly flow in central Kansas. The stratus
should linger until late morning (and perhaps early afternoon at
CNU) before scattering out.

A strong storm system will approach the Kansas region from the
southwestern states Thursday afternoon and night. Scattered severe
storms are expected to develop mid-late Thursday afternoon
near/just east of a dryline extending from west-central Kansas to
western Oklahoma, as a southwesterly mid-level jet streak
overspreads the area. Will carry VCTS at the
RSL...SLN...GBD...HUT...ICT terminals from mid afternoon on, and
at CNU Thursday evening. Prevailing south-southeasterly winds
gusting to 25-30 knots can be expected ahead of the dryline
Thursday afternoon.
