.SHORT TERM...(This evening through Wednesday)

It was a warm and muggy day over extreme southeast Kansas and the
Missouri Ozarks. Temperatures reached the low 90s while most
locations remained dry. We did have a few showers that were
developing over the eastern Ozarks this afternoon, and we could
see a few more develop in areas along and east of Highway 63. We
also could see a couple of strong storms develop as well.

For tonight, additional thunderstorm development will be possible
across southeast Kansas and western Missouri. A large complex of
storms is also expected to develop over Nebraska, and move into
the Ozarks Region during the Wednesday morning hours.

The CAPE - Shear combination looks strong enough for an episode of
severe thunderstorms, with large hail and damaging wind gusts
being the primary risks. There is also a localized flash flood
risk for any areas that experience slow moving or training
thunderstorms. This activity is expected to exit the Ozarks early
Wednesday afternoon.

.LONG TERM...(Wednesday Night through Tuesday)

For Wednesday night, look for more thunderstorm chances with
overnight lows in the low 70s. We will need to monitor for the
risk of excessive rainfall and flash flooding heading into the
Thursday. The NAM 12 and some other solutions are indicating that
several inches of rain will be possible somewhere either within
or near the Ozarks.

By Friday, there could be a few storms over far southwest
Missouri, however, we think most locations are looking dry through
Friday afternoon. However, thunderstorm development is very likely
Friday night into Saturday morning.

An upper level disturbance will approach from the west, bringing
numerous thunderstorms to the region during the day on Saturday,
and possibly extending into Saturday night.

The summertime high is supposed to creep a little closer to the
Ozarks by early next work week. This could bring warmer
temperatures, however, rain chances will also be in the offing
since the low center remains to the south and west of the area.
This upper air structure will keep the Ozarks within the overall
storm track.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1215 PM CDT Tue Aug 6 2019

A frontal boundary moving slowly into the region today will stall
across and linger into Wednesday. This weak boundary will become
the focus for shower and storm activity over the next 24 hours.
Most will see little impacts tonight but during morning hours,
increasing chances for storms will bring potential impacts to the
areas terminals. Where storms or heavy rains occur, visibilities
and ceilings will likely become MVFR.
