AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
407 PM CDT Wed Aug 6 2014

.SHORT TERM...(This Evening through Friday Night)
Issued at 402 PM CDT WED AUG 6 2014

Water vapor satellite imagery this afternoon shows a rather messy
upper level pattern in place across the Nation with negative height
anomalies to our east and positive height anomalies to our west, down
stream from a ugly little cutoff circulation --shear axis?-- spinning
over the Great Basin. Closer to home a shortwave trough is noted
slowly shifting east through the northern and central Plains. An
associated surface low is in central Kansas with a warm front
extending east into Missouri; roughly along a St Joseph to Moberly
line. Currently, convective activity is bubbling in eastern Kansas
and is expected to spread east into Missouri late this afternoon and
evening.

For this evening and through tonight...the shortwave moving east
across Kansas has bumped into an axis of high instability across
eastern Kansas, where MUCAPE values of 3000+ J/KG are present. This
has sparked storms in eastern Kansas, but limited shear -- 0-6KM
values struggling to reach 30 knots-- has left the storms  pulsing
up and down. This should limit primary hazards with storms late this
afternoon to damaging winds as individual storm cells collapse. This
activity is expected to spread east late this afternoon and into the
evening hours across western Missouri with the wind threat diminishing
later in the evening. The slowly veering jet under the shortwave
might be able to keep moisture focused across the Kansas-Missouri
state line tonight, which could result in redeveloping storms across
northeast Kansas and/or northwest Missouri late tonight. This could
result in repeated rounds of rain, and with precipitable water values
over 1 inch torrential rain may lead to some localized flooding
issues. However, have held off on any kind of Flood Watch product
though as basins in the region could stand to take a bit of rain
before flooding.

Thursday...convection is expected to be ongoing that morning as
the left over complex of storms slowly slides east. This could keep
a mix of showers and embedded thunderstorms percolating  across
Missouri through at least the first half of Thursday. More storms
may bubble up through the day, but the focus for activity looks like
it will have moved into eastern and southern Missouri likely
resulting in castoff showers and storms through the afternoon as the
upper level shortwave --to our west today-- finishes moving to our
east.

Friday...still more storms are forecast, but have backed off the
POPs considerably. By Friday we should be west of the shortwave
driving the activity tonight thru Thursday. This will leave the
frontal boundary sweeping through today wallowing around to our
south, so have trimmed POPs for the day Friday as isolated coverage
is all that looks possible at this time.

.LONG TERM...(Saturday through Wednesday)
Issued at 402 PM CDT WED AUG 6 2014

Second half of the weekend remains unsettled as upper flow remains
zonal with embedded shortwave troughs moving across the central
plains. Deep moisture will continue streaming in from the Gulf of
Mexico and models agree that additional shortwave troughs will
ripple through the flow through the weekend.

As we move into next week...the upper ridge over the Rockies will
amplify and increase the meridional flow over the CWA. This will
keep temperatures below normal early to middle next week and
decrease the moisture and thus precipitation chances for Tuesday and
Wednesday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
Issued at 1235 PM CDT WED AUG 6 2014

VFR conditions will great the afternoon hours at the terminals, but
these conditions might not last. Watching for the development of
thunderstorms late this afternoon across eastern Kansas. Current
expectations are for storms to bubble up after 21Z with widespread
activity likely tonight which will push ceilings down into the MVFR
range. After the main line of storms moves through tonight still
expect lingering showers and thunderstorms through Thursday morning
with MVFR conditions with surface winds veering to the southwest.
