AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
600 PM CDT Thu Aug 1 2013

...Update to aviation for 00Z TAFs...

.SHORT TERM...(This evening through Friday)
ISSUED AT 400 PM CDT THU AUG 1 2013

Southwest Kansas remains along the southern edge of the westerlies,
with upper level ridging to the southwest and troughing well to the
northeast.  Low level moisture has been enhanced by all of the MCS
activity over the past two weeks upstream of western Kansas.
Therefore, sufficient instability exists for deep moist convection
in the localized areas of moisture convergence, with surface based
CAPE values as high as 3000j/kg across western Kansas this afternoon.
Also, given the proximity of the upper level jet, decent shear
around 30 kts exists between 500 and 250mb to enhance evacuation of
precipitation from the updrafts. An area of cumulus clouds were
developing near WaKeeney early this afternoon and this could
evolve into a thunderstorm this evening. Given the aforementioned
shear and CAPE storms that develop have the potential to produce
hail as large as golf balls and wind gusts as high as 60 mph. The
HRRR suggests the possibility of convection over northeast
Colorado and northwest Kansas evolving into a larger cluster of
thunderstorms this evening while propagating to the southeast.
However, it is not at all clear is this scenario will actually
play out. Thunderstorms may also develop along the Colorado border
this afternoon and progress southeastward, but this scenario is
becoming less likely due to the lack of convection as of 3 pm. As
opposed to yesterday when there was much stronger low level
convergence and consistency among the various models, the
mesoscale models are showing very little model to model and run to
run consistency today. Therefore, we opted to keep modest 20%
chances for thunderstorms this evening.

South winds will stay up tonight as surface pressures fall across
the high plains. This will keep temperatures from falling much below
the 68-73F range. On Friday, a surge of southwesterly low level
downslope flow is advertised to develop across southwest Kansas as the
surface trough progresses into northwest Kansas.  This should allow
temperatures to warm to between 97F along interstate 70 to around
104F near Ashland barring any strong overnight convective clusters
and resultant cool outflow. The evolution of any convection Thursday
night will have an impact on what transpires Friday in terms of
thunderstorm activity. At the moment, widespread thunderstorm
activity is not expected due to weak low level forcing and lack of
a well defined upper level features. Due to the expected high
dewpoint depressions in the absence of any well defined,
unforeseen outflow boundaries, any severe threat should be limited
to damaging wind gusts and small hail.

.LONG TERM...(Friday night through Thursday)
ISSUED AT 247 PM CDT THU AUG 1 2013

The extended forecast well consist of multiple disturbances moving
around an upper level high across the Southern United States and
into the Central Plains. These disturbances will enhance lift as
well as increase instability in the mid levels of the atmosphere.
Meanwhile, ample moisture and frontal boundaries at the surface will
create enough lift to create thunderstorms across Western Kansas
periodically throughout the extended period.

A warm front is progged to move north across Southwest Kansas Friday
night into Saturday before stalling out across Northwest and Central
Kansas by Sunday morning. Partly cloudy skies are anticipated early
Saturday morning, increasing and becoming mostly cloudy by Saturday
night. A chance of thunderstorms will be possible along this
boundary, especially late Saturday afternoon into Saturday night
when POPs increase to above 50 percent. A slight chance of
thunderstorms will be possible Sunday along this boundary, but I'm
less confident that they will actually form. Otherwise anticipate
mostly cloudy skies and winds from the east to southeast. Another
fairly good chance of thunderstorms will be possible once again
Monday afternoon into Monday night as an upper level shortwave moves
into the Central Plains. As for temperatures, highs Saturday are
expected to range from the upper 80s across West Central Kansas to
upper 90s across the KS/OK border. Highs Sunday are forecasted to
range from the lower 80s across central Kansas to lower 90s across
the KS/OK border. Lows Saturday morning through Monday morning will
generally range from the upper 60s across West Central Kansas to
lower 70s across South Central Kansas.

The upper level high then shifts farther east into the Lower
Mississippi Valley during the middle of the week as an upper level
long wave trough treks into the Western United States. A few more
shortwaves are progged to move into the Central Plains during this
time bringing additional chances of thunderstorms to Western Kansas.
However, since this is out on day 6 and 7 confidence is low on the
exact position and timing of these thunderstorms. Otherwise expect
partly cloudy skies and winds generally from the east to southeast.
Highs Monday through Wednesday are forecasted to range from the mid
80s across West Central Kansas to lower 90s across the KS/OK border.
Lows Saturday morning through Monday morning will generally range
from the upper 60s across West Central Kansas to lower 70s across
South Central Kansas.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
ISSUED AT 600 PM CDT THU AUG 1 2013

VFR cigs expected through TAF pd. First item of concern is convection
located across the high plains of Eastern Colorado. Think this activity
will stay west of the terminals, but will watch/amend as needed. Southerly
winds of 10-20 KT expected tonight into early morning. Wind vectors
will become southwesterly 15-22 KT as lee induced low drops south across
NW to WC Kansas.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THERE IS A SLIGHT CHANCE OF THUNDERSTORMS FRIDAY AFTERNOON AND
EVENING. THE PROBABILITY OF WIDESPREAD SEVERE WEATHER IS VERY LOW,
BUT AN ISOLATED 60 MPH WIND GUST CANNOT BE RULED OUT.

THUNDERSTORMS ARE POSSIBLE EACH DAY FROM SATURDAY THROUGH
TUESDAY. IT IS TOO EARLY TO DETERMINE IF THESE STORMS WILL BE
SEVERE.

.SPOTTER INFORMATION STATEMENT...
