.DISCUSSION...
Issued at 309 AM CDT Thu Jun 20 2024

Water vapor imagery shows some shortwave energy coming onshore
over Central/Southern CA with some northern stream energy over
the Pacific Northwest. Meanwhile, upper ridging extends from
the Mid Atlantic States into the Lower Mississippi Valley. At
the surface, high pressure is situated over the Upper
Mississippi Valley into the Northern Great Lakes region, with a
weak cold front from Central IL through Central MO and starts
to wash out across Southern KS.

A few storms have been lifting across central KS overnight in an
area of weak 850mb moisture transport. By 12z, storms should be
tracking out of the forecast area. Not much is expected to
change in the overall pattern today with additional upper
energy digging over Central CA and upper ridging centered over
the Tennessee Valley. The best storm chances tonight will be
well north of the forecast area in an area of good low level jet
convergence. On Fri, the western CONUS impulse will start to
quickly lift northeast and will track across the Great Basin and
into the Central Plains Fri night into Sat morning. A weak cold
front will then track south on Sat as the upper wave moves into
the Mid Mississippi Valley. Front is expected to move through
Sat night with some scattered storms possible along it. However,
confidence is low on how widespread storms will be as our
forecast area will be pretty far removed from the better upper
dynamics. Strong to marginally severe storms will be possible
with any storms that develop Sat night.

The main story through this forecast package will be extreme
heat that is expected to build-in by the start of next week.
This will be the result of upper ridging strengthening from the
Desert Southwest into the Southern Plains with 30C 850mb temps
moving-in by Mon and remaining through at least Tue. This will
bring widespread highs at the century mark or even a few degrees
above. These highs will be around 10-15 degrees above normal.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 630 AM CDT Thu Jun 20 2024

Main aviation concern will be some low clouds this morning.

Currently have some LIFR cigs along and north of I-70 and these
are expected to stick around for another couple of hours before
quickly lifting north. After this, VFR conditions are expected
for the remaining sites through the remainder of the day. Winds
will come around to the southeast this morning at all sites.
