Area Forecast Discussion
National Weather Service Dodge City KS
600 PM CDT Wed May 10 2017

...Updated Aviation...

.SHORT TERM...(This evening through Thursday)
Issued at 133 PM CDT Wed May 10 2017

Showers and thunderstorms are likely tonight as a closed off upper
low moves east across New Mexico into the Texas Panhandle, initially
providing a difluent southwest flow aloft across the Western High
Plains. Southwest Kansas will continue to recover through this
afternoon as this morning's MCS moves out of south central Kansas,
in turn allowing low/mid level lapse rates to steepen while instability
rebounds with short range model soundings showing MLCAPE values pushing
upward of 1500 J/kg. With a marginal cap already weakening, thunderstorms
are expected to trigger late this afternoon into early evening as a
series of H5 vort maxima cycle out of the trough axis across the South
Plains and lift into southern Kansas. Considering where most the
favorable moisture/instability will be, the best chance for thunderstorm
development will be generally across central into eastern portions
of southwest Kansas, especially as a surface low shifts eastward
across the Texas Panhandle into western Oklahoma during this period.
Based on shear profiles and instability factors, the potential for
severe storms exists through mid to late evening with quarter to golf
ball size hail possible and damaging winds in excess of 60 mph. Limiting
a more expansive severe potential threat, including the potential for
significant tornadoes, will be a weakening southwest flow aloft as
an initial +70kt jet shifts eastward out of the area not to mention
weak 0-1km helicity. Still, cannot rule out the slight chance for an
isolated tornado or two, particularly closer to south central Kansas.

The focus late tonight will shift from a severe threat to a flooding
threat as a frontal boundary pushes slowly southward across western
Kansas, providing ample forcing within a modest unstable environment.
The closed upper low moving into the Texas Panhandle will interact
with the boundary triggering widespread rainfall near and along the
frontal boundary as it dips southward overnight. Strong QPF signals
and PW values upward of an inch suggest some areas could receive
rainfall totals in excess of 1 to 2 inches increasing the potential
for flooding, particularly in locations that have received recent
rain. Precip chances will gradually decrease west to east during
the day Thursday as the closed upper low moves further east across
the plains of southeast Kansas and northeast Oklahoma. Look for
lows generally down into the 50s(F) again tonight, especially with
increased cloud cover combined with areas of precip. Cooler air
will filter southward into western Kansas Thursday behind the
advancing cold front resulting in highs primarily in the 60s(F)
with near 70F possible in south central Kansas. A few upper 50s(F)
may be possible off to our northwest.

.LONG TERM...(Thursday night through Wednesday)
Issued at 220 PM CDT Wed May 10 2017

A drier period is likely Friday through the weekend as upper level
ridging moves eastward out of the Intermountain West into the Central
Plains during the period. A weak flow aloft and a lack of low/mid
level moisture will keep precip chances out of western Kansas through
at least Sunday night. A warming trend will continue through the
weekend as warmer air begins to advect into the region. Highs are
expected up into the 70s(F) Friday and into the 80s(F) Saturday.
Could see highs pushing the lower 90s(F) Sunday afternoon.

&&

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 600 PM CDT Wed May 10 2017

Complicated, uncertain TAF forecast with multiple amendments
expected. Thunderstorm development across SW KS has largely
failed so far this afternoon, with surface temperatures well
short of convective temperatures. All models insist on widespread
thunderstorm development starting around 02-03z, as cap weakens
and forcing from approaching cutoff low increases. As such, SHRA,
TS and CB are mentioned in the TAFs, with TEMPO groups included
where model consensus depicts most videspread convection. Outside
of convection, winds will trend NE tonight through Thursday
morning as associated cold front passes. Behind this front, do
have high confidence of widespread IFR stratus cigs impacting GCK,
DDC and HYS after 09z Thursday. Reduced vis in BR/RA expected as
well. Numerous rain showers and embedded thunder, with continued
low ceilings, will create poor flying conditions for much of
Thursday. Expect stratus to eventually lift to MVFR by 00z Friday.
NE winds will increase to 20-30 kts at all airports after 18z
Thursday, behind the departing cyclone.

This hazardous weather outlook is for portions of central...south
central...southwest and west central Kansas.

.DAY ONE...This afternoon and tonight.

Day 1 Discussion
----------------

Strong to severe thunderstorms will develop late this afternoon
and evening ahead of a strong upper level low pressure system
approaching across the Desert Southwest. The primary threats will
be quarter to golf ball size hail with an isolated chance for up
to tennis ball size hail and damaging winds in excess of 70 mph.
There is a limited risk for isolated tornadoes, particularly more
toward south central Kansas. The main threat will transition to
potential flooding later this evening through the overnight hours
as heavy rainfall is expected near and along a cold front as it
moves southward across western Kansas. The best chance for
excessive rainfall will be along and north of the Arkansas River.

Day 1 Hazards
-------------
* Tornado: Limited risk
* Hail: Elevated risk
* Thunderstorm wind damage: Elevated risk
* Flooding: Elevated risk
* Lightning: Significant risk

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Days 2-7 Discussion
-------------------

Thunderstorms will be possible again early next week. However, it
is too early to determine severe potential.
