AREA FORECAST DISCUSSION
National Weather Service Kansas City/Pleasant Hill MO
642 PM CDT Sat Jun 9 2018

.Discussion...
Issued at 256 PM CDT SAT JUN 9 2018

Another summer day, more subtle features to track that could have an
impact on weather in the area. First, there is an outflow
boundary/differential heating boundary in northeastern MO from the
short-lived bow echo that traveled into west central IL. This arcs
back into the extreme northeast portions of the forecast area and
could act as a focus for future storm development this afternoon.
Second, there is an area of convergence showing up in the surface
observations and satellite data in east central NE that is
tracking to the southeast into northern MO. Models don't seem to
know it's there and as a result don't produce anything from it
later this afternoon and this evening. From this convergent area,
an inverted surface trough extends to the north through northern
IA. Lastly, most of the area appears to be under an area of
subsidence from the MCS that dissipated over the area this
morning. This will likely suppress thunderstorm activity across
eastern KS and western MO. There is also strong warm advection at
700mb into eastern KS and western MO that should inhibit
convection there later this afternoon. Think for the afternoon
hours, the best chances for any thunderstorms will be in our
extreme northeastern zones with the outflow/differential heating
boundary.

Tonight, thunderstorms should develop in IA this afternoon and
organize into another MCS that tracks to the southeast. This may
eventually work into the northern and northeastern portions of the
forecast area around midnight, give or take an hour or two. The
NAMNest is the most bullish in bringing storms into the area
tonight. But given where storms should initiate and their
southeastward track, it seems like northern to northeastern MO has a
good chance at seeing storms during the overnight hours.

Sunday, heights and thicknesses increase over the area with very
warm 850mb temperatures spreading over the region. This indicates
that it'll be very hot for this time of year. The one thing that
could throw a wrench into things is if some convective debris moves
into the region and inhibits potential for max heating. Assuming we
see max heating, which at this point is the most likely scenario for
much of the forecast area, we could see highs in the upper 90s
across eastern KS and western MO.

For Monday, the thermal ridge builds eastward ahead of an advancing
cold front. This will result in another hot day across the area.
With dewpoints climbing into the upper 60s to around 70, extreme
instability should build. As the front advances into the
instability, thunderstorms are expected to develop late in the
afternoon/early in the evening. Shear looks marginal at this time
but given the strong instability there should be threat for
severe storms. Forecast soundings show a nice inverted V so it
seems like winds would be the most likely hazard.

For the rest of the forecast, cooler and drier weather should build
into the area Tuesday into Wednesday. But we get right back into the
heat and humidity later in the week and the strongest ridging out
west, it could potentially be active with MCSs moving into the area.

.Aviation...(For the 00Z TAFS through 00Z Sunday Evening)
Issued at 633 PM CDT SAT JUN 9 2018

Scattered showers and thunderstorms are currently moving through
western Missouri, effecting KMCI at the beginning of the forecast
for 1-2 hours. Another round of storms exiting Nebraska will have
a chance to effect KSTJ during the early portion of the forecast.
These storms are expected to push east of the TAF locations by
3-4Z, but may continue to cause issues over north central Missouri
through 6-7Z. The next chance for thunderstorm development over
northern Missouri will occur after 7-8Z when a line of
thunderstorms is expected to move in from Iowa at that time. This
may cause issues for any flights over northern Missouri through
sunrise and could even alter the wind directions at the TAF
locations if it makes it far enough south. After sunset the threat
of thunderstorms will diminish over the area with winds picking
up from the SW with gusts near 20-25kts in the afternoon.
