AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
937 AM CDT Thu Jun 27 2013
.MESOSCALE DISCUSSION...
Issued at 937 AM CDT THU JUN 27 2013
Convective complex over southeast Nebraska is beginning to encounter
a relatively stable airmass over northeast KS and northwest MO,
evidenced by latest ACARS sounding out of MCI. However, 12Z TOP
soundings shows that an unstable airmass is not far away to the west,
and this instability should spread eastward into western MO later
this morning and early afternoon assuming thick anvil clouds don't
significantly cut back on heating. This destabilizing airmass could
allow storms to redevelop through the afternoon, and may even allow
current convection over northwest MO to re-intensify as it spreads
into west central MO. A lot of the severe threat will depend on
remnant mid/high clouds and any outflow boundaries that will be
produced by ongoing convection. If clouds become too thick over
eastern KS/western MO it may shift the highest threat for afternoon
severe storms further west into central KS.
Increasing clouds from this thunderstorm complex could also put the
current heat advisory in jeopardy especially for the KC area.
However, dewpoints are already climbing higher than forecast, so even
just a little bit of sun should allow heat indices to climb into the
upper 90s or low 100s. Full sun could send them well over 105,
especially for areas south of KC. Therefore no changes to the
advisory are planned at this time.

.SHORT TERM...(Today through Saturday)

Thursday: The biggest concern for today centers on the possibility
of severe convection, including the possibility of significant hail,
widespread damaging winds and a few tornadoes.
As of around 07Z, an expansive ACCAS field was evident across
Nebraska and South Dakota with a few elevated showers developing.
This is ahead of a subtle shortwave trough noted on water vapor
imagery moving through/into Wyoming/Nebraska and South Dakota. This
shortwave will continue to move southeast and likely lead to an
increase in elevated convection over Nebraska this morning. How
expansive this cloud cover is from the convection will really impact
temperatures for this afternoon. Although the biggest impacts would
mainly be over the northeastern half of the forecast area. Southwest
of the cloud cover, very robust heating is expected to occur ahead of
a cold front that will be advancing southward through the region.
With ample moisture available and afternoon temperatures in the
middle 90s, extreme instability is expected to develop, possibly in
the 4000 to 5000 J/kg range. Mid to upper level flow will support
bulk shear in the 30 to 40 kt range, which combined with the extreme
instability, will be more than enough to lead to severe storms across
eastern Kansas and western Missouri. It will depend on where the
convection initiates, but the chances for significant hail, damaging
winds and a few tornadoes will exist with the initial severe storms.
This seems most likely to occur over northeastern Kansas and
northwestern Missouri. As the cold front advances, convection should
be able to congeal into a convective system that tracks in a
southerly direction across eastern Kansas and western Missouri. The
main threat will then become damaging winds.
Friday - Saturday: Much more comfortable conditions are expected as
drier air settles into the region. Friday high temperatures may
still be able to climb into the middle 80s to lower 90s but with
dewpoints falling into the 50s and 60s, it will feel much more
comfortable than the last week or so. For Saturday, troughing will
deepen across the eastern half of the CONUS with this extending into
our eastern zones. As the upper-level disturbance rotates through
during the afternoon, cooler air aloft, with some daytime heating,
may lead to isolated to scattered, unorganized shower/storms across
the northeastern half of the forecast area. Temperatures across this
area should be a fair amount below normal, with highs in the middle
70s to near 80. Further west, and potentially more removed from the
cloud cover and precipitation, temperatures should be very close to
normal.
.LONG TERM...(Sunday through Wednesday)
Issued at 258 AM CDT THU JUN 27 2013
An upper trough over the Great Lakes region this weekend will
gradually deepen and build westward through the first half of next
week, resulting in below normal temperatures across the area. At low
levels, high pressure over the northern and central Plains will keep
winds light and northerly, and should limit precipitation chances.
Currently, the best chance for precipitation will be on Sunday as
the base of the trough retrogrades into central Missouri, possibly
allowing for a few widely scattered showers and storms; and again on
Tuesday as another upper disturbance builds southwest into the
eastern Plains. More unsettled weather is expected for the end of
the period as a secondary low slides southward into the western edge
of the trough, deepening the system and providing a few more foci
for scattered convection. Highs throughout the period should be
generally in the upper 70s to lower 80s, which will be 5 to 10
degrees below normal throughout the region. Lows should also be
below seasonal normals, generally ranging from the upper 50s to
lower 60s.

.AVIATION...(For the 12Z TAFS through 12Z Friday Morning)
Issued at 625 AM CDT THU JUN 27 2013
Showers and storms developed earlier in the night across Nebraska and
have been tracking to the southeast. These storms have a chance to
hold together as they track into northwestern Missouri and may impact
the terminals from later this morning. The bigger threat for storms
still appears to be this afternoon as a cold front moves into the
area. Severe thunderstorms should rapidly develop across northeastern
Kansas and northwestern Missouri this afternoon and possibly impact
the terminals late this afternoon and early this evening. Once
convection moves south of the terminals winds will become light and
from the north with skies becoming clear.
River fog will affect STJ this morning. This should burn off rapidly
with in an hour or two of forecast issuance
