.DISCUSSION...
Issued at 309 AM CDT Wed Jun 19 2024

Storms developed along the cold front late Tue afternoon/evening
and with the help of outflow the storms and effective cold front
currently stretches from the northern TX Panhandle, into
southern KS and to north of Kansas City. The shortwave that
allowed the front to push south is currently moving into the
Upper Mississippi Valley.

Current thinking is that showers and a few storms will linger
this morning across south central and parts of central KS as
850mb flow remains out of the south even north of the surface
front. A high PW airmass will also remain in place today, with
PW values around 175% of normal. For this morning is looks like
the best chance for heavy rainfall and widespread flooding will
be southwest of the forecast area of western OK into the TX
Panhandle where low level jet will remain more backed resulting
in better convergence. However, high rainfall rates will be
likely across our area with the more intense activity which may
lead to additional localized flooding. We should see a gradual
decrease in shower/storm coverage this afternoon as the front
starts to wash out and the better isentropic lift shifts north.

By Thu morning, upper ridging will extend from the Mid Atlantic
States into the Tennessee Valley. Meanwhile, there is good model
agreement that some shortwave energy will be coming onshore over
central/southern CA with a northern stream impulse tracking east
across the Pacific Northwest. For Fri, upper ridging is expected
to expand into the Ozark region and lower Mississippi Valley.
The Western CONUS upper energy is then expected to quickly track
across the Great Basin on Fri night and across the Central
Plains. This will allow a weak cold front/surface trough to push
south, moving through KS on Sat night into Sun and after today,
will bring our next shower/storm chances. However, confidence is
low that we will see anything as widespread as we are seeing
right now, as the front/trough that moves through will be very
progressive. For the the start of the next work week, there is
good agreement between the GFS and ECMWF in upper ridging
building from the Desert Southwest through the Southern Plains
and will allow anomalously warm 850mb temps to move-in from the
southwest, bringing widespread highs around 100.

.AVIATION /18Z TAFS THROUGH 18Z THURSDAY/...
-- Changed Discussion --
Issued at 1227 PM CDT Wed Jun 19 2024

Cloudy skies with MVFR and some brief IFR CIGs can be expected
this afternoon along with some occasional light rain or showers.
There is a slight chance for a brief thunderstorm with this
activity but if it occurs, it will not last long. By 00Z
tonight, the rain will come to an end across the region but MVFR
CIGs are still expected through the overnight period. Do not
think IFR CIGs will occur but it is not out of the realm of
possibility. Otherwise, no significant aviation weather issues
are expected for this TAF period.
