202 AM CDT Wed Aug 9 2023

Forecast Highlights:

* Severe Storms early this morning

* Heat looks to return on Friday with heat indices possibly
  approaching 105 in the afternoon

* A couple rounds of storms look to affect the region during the
  Friday night through Monday period

.SHORT TERM...(Today through Friday night)
Issued at 200 AM CDT Wed Aug 9 2023

Current early morning satellite water vapor imagery shows the
healthy upper level weather system over Wyoming/Colorado moving
eastward. Storms are beginning to develop into a larger complex of
storms over western Kansas. This complex of storms is expected to
gain momentum and grow upscale as it moves eastward across central
Kansas. In addition we could see another area of storms develop over
southern Kansas ahead of this complex where low level jet focus is
increasing. The two areas of storms will merge and continue a
east/southeast movement with damaging to significant damaging winds
likely. The convection will linger over eastern Kansas this morning
then shift east into Missouri by this afternoon, as the upper level
system tracks eastward with associated cold front pushing southward
across Kansas today. A dry weather pattern looks to be on tap for
Thursday with surface high pressure over the region. Models do show
a signal for some mid-level warm advection Thursday night maybe
generating more elevated convection, across far southern Kansas with
better chances for Oklahoma.

Heading into Friday the heat looks to increase for Kansas where heat
indices could reach possible advisory levels of 105 degrees. Yet
another signal for night-time storms could affect the region Friday
night.

.LONG TERM...(Saturday through Tuesday)
Issued at 200 AM CDT Wed Aug 9 2023

Upper level flow will be more west/northwest for the weekend with
models showing a couple embedded waves migrating across the central
plains. This looks to induce some mid-level warm advection which
would give way to thunderstorm chances. Meanwhile heading into early
next week the upper level flow becomes more northwest flow
orientated with surface high pressure building over Kansas. The mid-
level baroclinic zone becomes more north to south aligned by Monday,
and a signal for warm advection across it could spark off another
round of storms Monday night.

&&

.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1226 AM CDT Wed Aug 9 2023

We are still expecting scattered to numerous thunderstorms to
impact the region overnight into Wednesday morning from west to
east, as an upper shortwave approaches from the west, interacting
with increasing low to mid level warm/moist advection. Activity
has increased eastward over western Kansas the past few hours
based on regional radar trends. Degree of instability combined
with unseasonably strong deep layer effective shear will support
strong to severe storms, with damaging winds, large hail, and
locally heavy rainfall the primary concerns. Included prevailing
VCTS and TEMPO TSRA at all sites overnight into early Wednesday
morning.
