.DISCUSSION...
Issued at 248 AM CDT Thu Jul 28 2022

Forecast Highlights:

- Cooler temps with rain chances mainly early this morning and again
Saturday night into Sunday.

- Warming up again early next week.

A large upper level system remains anchored over the Eastern Canada
just south of the Hudson Bay region. Broad cyclonic flow stretches
from the northeastern sections of the CONUS through the Ohio Valley
into the northern Plains with a long wave ridge building over the
western CONUS. A weak frontal boundary is currently stretched over
portions of east central Kansas areas into central Kansas with a
more well defined frontal boundary over east central into central
Nebraska being pushed slowly south by a low to mid level shortwave
translating through the central Plains on the southwestern flank of
the broader cyclonic flow aloft.

Earlier, some severe storms fired along this northern boundary in
Nebraska and were enhanced by the forcing aloft. These storms have
be trending weaker overall for the past couple of hours. But, some
stronger updrafts continue at this hour as they slowly move into
north central KS areas. Weak isentropic lift is developing along the
305-310K surfaces which is helping some new showers and storms
develop southeast of these storms now making their presence known
just to the west of the forecast area and getting ready to move into
portions of the Cloud county. CAMS have had this general idea for
the past several cycles and therefore have kept mention of showers
and storms developing into the early morning hours before decaying
over the area by around midday. Not anticipating severe weather with
these storms as shear is very weak and instability isn't very
impressive. So elevated showers and storms should still provide
beneficial rainfall to a few areas. Will mostly be watching for
potential for localized flooding if any training sets up over areas
that see development as slow motion could allow for moderate to at
times heavy rainfall to accumulate quickly.

A modified surface high pressure cell expands into the area later
this afternoon through much of the Friday and early Saturday period.
This should limit rain chances until it slides east into Saturday
afternoon and evening which rain and storm chances increase once
again before the heat sets up for early next week. As the western
ridge builds into the area return flow will bring back higher theta-
e air helping to increase dewpoints back into the 70s which will of
course make the afternoon heat index values reach near advisory
levels at times into next week. Will have to practice heat safety
once again into the first week of August.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1215 AM CDT Thu Jul 28 2022

Not much change to the going forecast for now. Trends with storms
over western Nebraska are suggesting more southerly movement
overnight and thus may not impact the terminals. A little early to
remove mention of showers and storms for now so have left as is in
the event development into the area takes place on any outflows.
