.SHORT TERM...(This evening through Wednesday)
Issued at 332 PM CDT Tue May 29 2018

As of 19Z Tuesday afternoon satellite and surface analysis revealed
a remnant outflow boundary from this morning's convection extending
from the OK panhandle eastward near Alva, OK and northward from
there into central KS. An upper low was positioned across eastern
WY/western NE/SD. A shortwave trough has begun ejecting from the
base of the upper low across portions of the central Plains. Ahead
of the main upper level forcing, isentropic ascent within the 310-
315K layer coupled with eroding ML inhibition has yielded isolated
to scattered thunderstorms across central and north central KS.
Modest effective bulk shear on the order of 20-30kts has limited
storm organization to this point. Short-term model solutions
continue to struggle with convective trends but do expect further
development across central KS by late afternoon as the main upper
shortwave trough overspreads the CWA. An associated H5 speed max --
35-40kts -- may slightly increase the effective bulk shear and storm
organization by evening. Expect initial storm mode to be
predominately multicell with some supercell structure. Eventual
upscale growth into an MCS appears likely. CAM and short term
solutions suggest the MCS should traverse all of the CWA with large
hail and damaging winds the primary concerns.

In north central KS, latest HRRR/RAP runs suggest an impressive
veering low level wind profile amid the recovering outflow.
KCNK/KSLN forecast soundings at 23Z yielding ESRH values of 200-300
m2/s2 which would support tornadogenesis in the 22-01Z timeframe.

The 12 KTOP RAOB observed a PWAT of 1.35" which approached the 90th
percentile for May 29th. This tends to suggest heavy rainfall with
the potential for localized flooding. As the upper shortwave trough
pushes northeast of the CWA overnight, shower and thunderstorm
activity should be well east of the area by sunrise Wednesday. Zonal
flow settles in for the day Wednesday with subsidence behind the
shortwave trough should yield sunny skies and highs near 90.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 332 PM CDT Tue May 29 2018

There remains to be some potential for elevated convection
Wednesday night into early Thursday as a decent late spring upper
level jet ushers in a weak wave that is off the southwest CONUS
coast today. Modest isentropic upglide develops in mainly southern
areas as this wave passes, though the NAM is more aggressive with
low-level moisture return into northern Kansas. Effective shear
and instability continue to look fairly limited and should keep
severe weather potential (mainly hail) small. Still some chance
for the effective surface boundary to linger over southern areas
Thursday night and another area of moisture convergence aloft in
the far northeast for small chances in these areas, though again
shear and instability are not impressive at this range.

Should see a general rise in high temperatures outside of convection
Thursday and Friday, as heights steadily rise between the exiting
shortwave and the next wave in the northern branch reaching the
northern Plains. Models are in good agreement with 850mb temps
reaching near 25C and southerly winds bringing dewpoints to around
70F for air temps in the mid 90s to around 100F Friday and heat
indicies approaching Advisory levels. Capping inversion with 700mb
temps near 15C should keep convective chances low Friday, with small
potential for storms associated with northern wave to pass across
northeast sections on the edge of the cap Friday night. Specifics of
timing with this wave and associated Pacific cold front continue to
vary, but cooler and less humid air should build in by late Saturday
and continue into Sunday with continued capping aloft keeping
thunderstorm chances with frontal passage low.

Into early next week, model spread increases with how strong the
upper ridge amplifies. Will keep some small precip chances mainly in
nighttime hours at this point with highs likely slowly rising.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 637 PM CDT Tue May 29 2018

Numerous showers and thunderstorms will move through northeast
Kansas through 06-10Z Wednesday morning with localized MVFR to
IFR restrictions possible in the heaviest storms. Gusty winds of
30 to 50+ kts and large hail will be possible as well with the
stronger storms. Patchy fog may develop on the backside of the
storms prior to sunrise, with VFR conditions and light westerly
winds for the day on Wednesday.
