National Weather Service Springfield MO
312 PM CDT Wed May 29 2019

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

A large area of rain and thunderstorms expanded across much of the
Ozarks region this afternoon. Severe weather chances were quickly
dwindling, and we'll likely remove most counties out of the watch
soon.

The risk for some localized flash flooding continued however, as
soil conditions remain nearly saturated.

Rain will exit the region this evening over shortly after
midnight. Look for lows tonight to fall into the upper 50s or low
60s.

.LONG TERM...(Thursday through Wednesday)

Continental air will spread into the region for Thursday through
Saturday morning. Highs will only be in the 70s for Thursday, with
readings in the low 80s on Friday.

Moisture moves back in on Saturday, with increasing rain chances
Saturday afternoon into Saturday night. The region will be under
northwest flow over a Gulf airmass spreading in underneath. This
could bring some localized heavy rainfall. Some locations may not
receive any rain through the weekend.

Weak northwest flow will continue through next work week, as
several small disturbances approach from the west. This could
trigger several rounds of scattered convection.

Temperatures and humidity will be normal for June, with highs in
the 80s and lows in the 60s.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)

Pilots flying in and out of the southwest Missouri airports will
need to monitor radar trends through the rest of the afternoon and
evening.

Thunderstorms have developed, and will be impacting a large
section of the Missouri Ozarks this afternoon. The heaviest and
most persistent thunderstorms will occur over the Branson airport,
where severe weather and flash flooding will be possible in this
region. Airfield directly impacted by storms will experience a
reduction in ceilings and visibilities.

Storms are expected to shift east of the area by this evening or
overnight.

Safe Travels.
