AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
606 PM CDT Thu May 8 2014

.DISCUSSION...
Issued at 246 PM CDT THU MAY 8 2014

Still expect convective initiation to occur over the next few hours
along a cold front which is moving into eastern KS this afternoon.
Shower activity over MO has been light in coverage and intensity, so
airmass to the east of the front has not stabilized too
significantly. Aircraft soundings out of MCI still indicate a weak
capping inversion near 850 hPa where temperatures are around 16C.
These will need to cool to around 14C to reduce inhibition enough for
thunderstorms to develop, and most models indicate this will occur
over the next couple of hours as the upper trough approaches from the
west.

Still believe storms are likely to initiate close to or just west of
a Maryville to Topeka line later this afternoon, and approach the
I-35 corridor near or just after 7 PM. Temperatures rising into the
upper 70s and lower 80s across eastern KS will allow CAPE values to
rise into the 1000 to 1500 J/kg range through the afternoon,
potentially higher. This combined with 0-6km shear values between 40
and 50 kt will allow for some of these storms to become severe with
large hail and damaging winds. Storms will likely reach their peak
severity across a corridor from near Lawrence to St. Joseph and
Maryville where the greatest instability exists, and storms here could
briefly become supercells with very large hail and perhaps an
isolated tornado. The severe threat will decrease further east toward
I-35 where storms may take the form of a line with hail and scattered
damaging winds, and even lower probabilities of severe storms exist to
the east of US 65.

Most precipitation will exit the area toward midnight as the cold
front pushes into central Missouri. However, a secondary mid-level
shortwave rounding the base of the primary upper trough could provide
another wave of showers and thunderstorms from eastern KS into
western and central MO late tonight and early Friday. Best chances to
see this activity will be south of I-70. Elevated instability by this
time will be minimal so storms should stay below severe limits,
although with continued strong deep-layer shear it wouldn't be
surprising to see some small hail with these storms.

The frontal boundary will stall over the Ozarks Friday night and
return north over the weekend. This will set the stage for a
potentially active period Saturday afternoon through Monday as a
deepening trough to the west sends multiple impulses into the region.
This could result in several rounds of thunderstorms as these waves
interact with the quasi-stationary frontal boundary. The first round
of storms could develop as early as Saturday afternoon when most
models bring the warm front into Iowa leaving the entire forecast
area warm and unstable. Will need to watch for some strong storms
given potentially strong instability, but marginal shear and a lack
of a defined forcing mechanism should prevent a widespread severe
threat on Saturday.

By Saturday night and Sunday morning a more significant threat for
widespread thunderstorms will exist as a strong low-level jet noses
into eastern KS and western MO and interacts with the boundary in
place. NAM is a particularly interesting solution with very strong
moisture transport advecting toward the boundary which results in
several inches of rain near the MO River. Whether this heavy rain
threat is actually realized is dependent on a lot of factors
including location of the front and magnitude of the low- level jet.
So it's too early to say if heavy rain and severe thunderstorms are a
real possibility Saturday night and early Sunday but it certainly
bears watching.

Additional thunderstorms are possible Sunday afternoon through Monday
as the upper trough to the west deepens and a cold front moves
through the area. Severe potential this period will depend on the
exact timing of the front, airmass destabilization in the wake of
earlier storms and wind fields ahead of the upper trough which won't
be known for a few days. Forecast becomes more benign by midweek with
cyclonic upper-level flow bringing drier conditions and cooler
temperatures.

Issued at 604 PM CDT THU MAY 8 2014

VFR conditions expected during the TAF period. Scattered
thunderstorms will move over/near terminals now through 03Z. A brief
reduction of ceilings/visibility may be possible in the heaviest
activity. Otherwise, conditions are expected to gradually improve
during the late evening/overnight, with a wind shift out of the west-
northwest.
