AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
1201 AM CDT Thu Jun 5 2014

...Update to aviation...

.SYNOPSIS...
ISSUED AT 1000 PM CDT WED JUN 4 2014

The 05.00Z 250-hPa map showed a westerly jet streak of 70-80 kt moving
across Colorado. At 500-hPa, quasi-zonal flow prevailed across much
of the CONUS. At the lower levels, a stout cap (20C) roughly at 767-hPa
was noted at KDDC, although with steep lapse above said constant pressure
level. KDDC pwat was still fairly high at 0.94", and in between the 50th
and 75th percentile. At the sfc, a frontal boundary was noted across
the Southern Plains. Convection prevailed upstream across the Colorado
Plains.

&&

.SHORT TERM...(This evening through Thursday)
ISSUED AT 145 PM CDT WED JUN 4 2014

Severe thunderstorms are the main challenge in the forecast late
tonight. We have bumped up POPs to categorical (80 percent or
higher) in the areas mainly between Jetmore and Hays. It is still
fairly unclear exactly how the event will unfold overnight, however
the strongest signal in the various mesoscale model solutions is
that as storms approach the western Kansas border during the late
evening hours, they will start to organize into a more organized
cluster of strong/severe storms as warm frontogenesis increases
markedly after 06Z Thursday. The NAM12, in particular, is suggesting
strongest convective development initiating around 700-750mb where
lifted parcels from this level will have as much as 2000 to perhaps
3000 J/kg CAPE. The directional shear environment will be very
favorable for vigorous severe thunderstorm updrafts, most likely
supercells initially.  There will eventually be a transition toward
a quasi-linear mode where 65 to 75mph thunderstorm wind gusts will
become the more dominant threat. Orientation of the frontogenetic
zone with forward motion of storms to the east-southeast would
suggest a very heavy rainfall threat as well...with over 2 inches of
rain quite likely along a narrow corridor where the most numerous
storms train over some of the same general areas. The severe weather
threat will shift deeper into central Kansas by daybreak, so will
taper the POPs off by 12Z. Cooler northeast winds will be found in
the wake of the mesoscale convective system on Thursday. The front
at the surface Thursday will be far enough south from Kansas to
preclude any surface-based thunderstorm threat during the late
afternoon/early evening hours.

.LONG TERM...(Thursday night through Wednesday)
ISSUED AT 340 PM CDT WED JUN 4 2014

The medium range forecast models continue to show a fairly active
flow regime over the lower 48 states through the extended period. At
the beginning of the period from Thursday night through Friday
night, a strong southern branch of the westerlies will extend from
southern California into the central Plains with upper level
disturbances moving through the flow. In the lower levels, a quasi
stationary frontal boundary will extend from the eastern slopes of
the Rockies in Colorado eastward across the Panhandles and northern
Oklahoma. An easterly upslope flow of moist, unstable air will be in
place across western Kansas and eastern Colorado. This is a
favorable pattern for late afternoon and nighttime thunderstorms
developing off the higher terrain of eastern Colorado and moving
through western Kansas.

This setup will be in place Thursday night. The models vary somewhat
on the placement of the heaviest precipitation or whether any storms
will make it out into western Kansas. The short term NAM model is
suggesting that the lower levels of the atmosphere will become
fairly stable in the wake of tonight's storms. Not totally buying
into this just yet as all the models show warm advection developing
overnight.

On Friday afternoon and night, the lower levels should be primed for
another round of thunderstorms. The models show a somewhat stronger
disturbance moving out of the Rockies. There appears to be a bit of
a coupled upper jet structure with this wave which will only enhance
upward vertical motion for thunderstorm development. Thunderstorms
may be ongoing into Saturday morning over central Kansas as the
disturbance moves out. The models show the frontal boundary getting
pushed farther south by late Saturday so chances for thunderstorms
will be somewhat less Saturday night. Another wave dropping out of
the northern Rockies Sunday into the northern and central Plains on
Sunday will bring a chance for some late afternoon and evening
thunderstorms to far western Kansas. The next significant chance for
storms may occur around next Tuesday night or Wednesday as a strong
upper level shortwave trough is forecast to move across the northern
Rockies and adjacent High Plains.

.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
ISSUED AT 1200 AM CDT THU JUN 5 2014

Main concern is watching convection across eastern Colorado in the short
term. Radar trends and mesoscale model trends support main flight impacts
to KHYS in the 08Z-10Z time frame. An outflow boundary could impact
KGCK/KDDC, but most of the TSRA should be just to KHYS. MVFR cigs will
prevail through morning with VFR by noon or so.
