.DISCUSSION...
Issued at 239 AM CDT Mon Jun 17 2024

Water vapor imagery currently shows a shortwave trough digging
over the Northern Intermountain with upper ridging over the
Southeast CONUS. At the surface, cold front extends from
Northern IA into central Nebraska and into far nw KS, with
elevated storms north of the front over northern Nebraska.

Lee troughing will further strengthen today as upper shortwave
approaches the Northern/Central Rockies. This will allow for
strong south winds by early this afternoon, especially for
areas along and especially west of I-135. In these locations we
are looking for sustained speeds around 30 mph with gusts 40-45
mph. Also looking for these strong winds to continue into the
early evening hours.

By Tue morning, upper energy will be moving out into the
Northern High Plains and at the same time cold front will slowly
make its way south. By 21z Tue the front is expected to stretch
from Eastern Nebraska to just north of KHYS and into western
KS. Storms are expected to develop along the front late Tue
afternoon and will become more numerous in the early evening as
low level jet impinges on the front. The big question will be
how far south storms are able to make it, with the better upper
support further north along with capping issues to the south.
For now will go with the thinking that locations along and north
of I-70 will have the higher storm chances. On Wed, cold front,
likely reinforced by outflow, will be draped across north-
central KS which may allow some convection to linger, at least
through the morning hours. However, by Wed evening into Thu, the
better storm chances will lift back into Nebraska.

By early Thu morning, upper troughing will continue to linger
over the Great Basin into the Desert Southwest. At the same
time, an upper impulse is expected to lift out of the Gulf and
into southwest TX by Thu morning. So to end the work week, the
better storm chances look to stay north and west of the forecast
area along with to the south associated with the tropical wave.
Upper energy is then expected to quickly lift out of the Great
Basin and across the Central/Northern Plains Fri night into Sat
morning. However, the better rain chances look to be north of
the forecast area, closer to the better upper dynamics.

Strong south winds will be the main aviation concern today.

Still looking for strong south winds by early this afternoon,
with sustained speeds around 30-35mph with gusts 40-45 mph.
Locations along and especially west of I-135 will see the
highest wind speeds today. Look for the strong winds to even
continue after 00z. Confidence remains high that VFR conditions
will remain in place through the next 24 hours.
