...Updated Aviation Section...

Issued at 221 PM CDT SUN AUG 17 2014

Cold front has shifted to along the Missouri/Arkansas border early
this afternoon. Convection has just initiated along and ahead of
the boundary in far northern Arkansas into the bootheel region of
Missouri. At this point, planning on maintaining low end isolated
thunderstorm chances for far southern Missouri this
afternoon/evening to account for the vicinity of the front and
higher instability right along the border. Main convective
activity however will be further southeast in association with the
front and upper level disturbance over the Tennessee valley region.

Sun has helped to burn off the clouds in the southwest half of the
CWA today, but remain in the northeast and have kept temperatures
down there.

Will have another low end chance of convection in the Monday night
to Tuesday time frame, but overall rain chances through the entire
period look to be on the low side. Our main focus for the upcoming
7 day period will be with increased temperatures and humidity as
an upper level ridge begins to build over the lower and mid
Mississippi valley region by mid to late week.


.SHORT TERM...(This Evening through Monday)
Issued at 221 PM CDT SUN AUG 17 2014

Frontal boundary will be along the Missouri Arkansas border this
afternoon/evening and with increased instability along the front,
will maintain isolated thunderstorms across far southern Missouri
into the mid evening hours.

Shortwave energy will pass to the south of the area on Monday with
a stronger shortwave across the upper Mississippi valley region
leaving our CWA in between systems and generally dry throughout
the day. Daytime temperatures will range from the mid 80s in the
eastern Ozarks to the mid 90s over far southwest Missouri into
extreme southeast Kansas with heat index values from the upper 90s
to around 101 possible there.

.LONG TERM...(Monday Night through Sunday)
Issued at 221 PM CDT SUN AUG 17 2014

Another weak front and upper level energy will move into the area
late Monday night into Tuesday, however the bulk of the upper
level energy will remain north of our area and only carrying low
end pops with this feature for now.

After that, we will begin to see height rises as an upper level
ridge begins to build over the lower into mid Mississippi valley
area which will likely keep the storm track to our north and see
temperatures rising back into the mid to upper 90s for mid week
into next weekend. Heat index values will likely be from the upper
90s to around 104 through that period.


.AVIATION...(For the 00Z TAFS through 00Z Monday Evening)
Issued at 624 PM CDT SUN AUG 17 2014

Challenging forecast for the overnight period as patchy fog
development is possible. Scattered thunderstorms across northern
Arkansas will continue to move away from BBG early this evening,
with quite conditions expected for all TAF sites through the next
24 hours. Temperatures will approach/exceed their afternoon cross
over values overnight tonight, resulting in patchy fog. At this
point, have favored BBG and SGF for a period of IFR visibility.
For now, will handle with TEMPO groups. Any fog will quickly
dissipate Monday morning and VFR conditions are expected
