...Update to Aviation for 00Z TAFS...

.SHORT TERM...(This evening through Friday)
Issued at 252 PM CDT Thu Oct 6 2016

Morning showers and storms have mostly dissipated as the LLJ began
to decay this morning and early afternoon. Additional development
is occuring down in the vicinity of Table Rock Lake on the edge of
the cold pool from earlier convection.

Additional showers and storms have already started developing
across central KS/OK. CAMs is showing this activity developing
into a complex of storms with east/northeast progression. Timing
and a contaminated airmass from earlier convection will generally
limit the overall severe potential, however, a strong storm or
two may be possible west of I49 with gusty winds being the primary
threat.

Flooding may become a concern over southeast Kansas and southwest
Missouri overnight as additional heavy rainfall is expected with
the next round of storms overnight.

The surface frontal boundary and parent short wave is projected to
move through the region Friday morning/afternoon. Any
precipitation should come to an end quickly. Breezy, cooler, and
drier conditions are expected behind the frontal boundary.

.LONG TERM...(Friday Night through Thursday)
Issued at 252 PM CDT Thu Oct 6 2016

The long term starts with a ridge building across Texas expanding
eastward into the Gulf of Mexico through the weekend. A zonal
pattern sets up over us through the weekend. Dry and mild
conditions are expected through early next week.

A subtle wave is projected to move into the region on Monday. With
little return flow and poor moisture quality, think this period
will be dry with perhaps an increase in cloud cover. If enough
moisture can come together we may see an isolated shower or two,
however, left mention of this out for now.

Zonal flow returns through the remainder of the long term with a
warming trend expected by the end of next week as a ridge begins
to build into the region.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 640 PM CDT Thu Oct 6 2016

For the KSGF, KJLN, and KBBG TAFS: A cold front is currently
pushing east across central Kansas early this evening. Storms are
developing along the cold front across central Kansas and also
ahead of the front across east central Kansas. The storms ahead of
the front across east central Kansas will continue to lift
northeast this evening and not affect the TAF sites.

The cold front will spread east into the area later this evening
into the overnight hours. A line of storms will push into far
southwestern Missouri later this evening, with showers and storms
expected to linger behind the front/leading line of storms for
several hours tonight. The storms will generally weaken as they
spread east and could totally dissipate before reaching the KSGF
and KBBG sites. The storms are expected to impact the KJLN site
later this evening into tonight.

Winds will switch from the southeast to northwest behind the front
overnight. MVFR and possibility IFR ceilings will be possible
behind the front early Friday morning.
