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

Thunderstorms have developed this afternoon as a frontal system
sagged into the region from the north. A few of these updrafts
could become organized, containing hail up to the size of quarters
and wind gusts in excess of 60 mph.

Afternoon temperatures have warmed into the middle and upper 80s,
yielding mixed layer cape values of 2000 to 2500 j/kg. While shear
is on the low side, moderate instability and moist mid levels will
allow some organization.

Residual storms will be possible into the overnight hours,
especially across far southern Missouri. Eventually this activity
will shift out of Missouri, bringing dry and cool weather for
Friday. As a matter of fact, temperatures Friday afternoon will
struggle to warm out of the 70s.

.LONG TERM...(Friday Night through Thursday)

By Friday night, mid level baroclinicity tightens up across the
Central Plains. This will force thunderstorms to develop across
Kansas, eventually shifting far western Missouri Saturday morning.
It's a little uncertain how far east this activity can survive,
but areas west of Interstate 49 have the best chances for rain
Saturday morning.

Additional storms are expected to develop on this same feature
Saturday afternoon and night, and we think most locations across
the Ozarks stand a good chance at getting wet. These storms will
linger into Sunday as a short wave trough tracks across the
region. Temperatures could be capped in the 70s on Sunday due to
precip and cloud cover.

A heavy rain set up then takes shape for Sunday night through
Monday Monday afternoon. A frontal system temporarily hangs up
across far southern Missouri and northern Arkansas. Periods of
excessive rain could develop along this feature, potentially
creating some localized flash flood issues.

The GFS forces the front south by Tuesday setting the stage for a
couple of quiet days. Ultimately temperatures will stay below
normal with afternoon highs in the upper 70s and low 80s on a
daily basis over the next several days.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1231 PM CDT Thu Aug 3 2017

Generally, VFR conditions are expected through this TAF cycle.
That being said, there will be a chance for isolated
showers/T'storms through the afternoon and into the early evening
hours as a cold frontal boundary moves through the area. This
activity should remain rather isolated at best, however, locations
that receive rain will experience some reduction in cigs/vis.

Winds will shift from a westerly/southwesterly direction to a
more northerly direction over time. This will signify the passage
of the cold front due into southern Missouri by early
evening/sunset timeframe.
