1231 PM CDT Sat Aug 23 2014

Issued at 920 AM CDT SAT AUG 23 2014

A weak outflow boundary or wave was moving to the east across
southwest Missouri this morning. a few showers had developed on
this boundary and and should continue to develop and remain
through this morning and into this afternoon as this weak boundary
slides slowly to the east. Precipitation with these showers will be
very light, less than a tenth of an inch.

As the boundary progresses to the easy into this afternoon, a
weakening cap may allow for additional, more widespread showers
to develop. A few isolated rumbles of thunder will also be
possible as the cap weakens and the storms take advantage of the
ample instability.


.SHORT TERM...(Today and Tonight)
Issued at 241 AM CDT SAT AUG 23 2014

Little change in the overall weather pattern is expected through the
weekend, as an upper level ridge remains centered over the lower
Mississippi Valley.  Temperatures today should be just a degree or
two warmer than yesterday, with 850 MB temps progged to warm by a
degree. Somewhat drier mid level air is expected to build in the
region today as well, which should result in a more pronounced drop
in dewpoints during the afternoon hours, especially along the higher
terrain of the Ozark Plateau.  Dewpoints along the spine of the
Plateau should drop into the low 60s, with somewhat higher readings
in the mid to upper 60s along the edges of the CWA, where terrain is
lower.  The end result will be another day of 100-107 degree heat
indices.  The Heat Advisory will continue unchanged.

.LONG TERM...(Sunday through Friday)
Issued at 241 AM CDT SAT AUG 23 2014

Similar conditions to today are expected for Sunday and Monday, with
highs again in the upper 90s and low 100s.

By Tuesday, the upper level ridge is expected to shift a bit east of
the region, with mid level troughing moving east across the Rockies
and into the northern High Plains.  Conditions Tuesday will remain hot
and humid, though the weakening of the upper ridge will allow for
scattered afternoon thunderstorms.

By Wednesday, things become a bit murky, with the GFS continuing to
insist on a significant frontal passage Wednesday/Wednesday night.
The latest ECMWF, on the other hand, is much slower with the front,
and brings the boundary very slowly across the Plains, not reaching
the Ozarks until next weekend.  The arrival of that front--whenever
that is--will bring our next significant rain chances, along with
cooler temperatures.


.AVIATION...(For the 18Z TAFS through 18Z Sunday Afternoon)
Issued at 1229 PM CDT SAT AUG 23 2014

High pressure will remain in control of the regions weather for
the next 24 hours. No impacts to aviators are expected through the
forecast period.
