Area Forecast Discussion
National Weather Service Dodge City KS
301 PM CDT Mon Jul 23 2018

...Updated short and long term discussions...

.SHORT TERM...(This evening through Tuesday)
Issued at 301 PM CDT Mon Jul 23 2018

Isolated showers and thunderstorms were forming across parts of
west central Kansas this afternoon from south of Goodland to near
Scott City, in a favorable area of low level moisture and
instability. The HRRR has been focusing some isolated development
in this area for the past several runs. Deep layer shear is pretty
weak in this area so am not expecting any organization from these
storms through the late afternoon which is also what the HRRR has
been showing. Better instability and shear has been farther west
into the Front Range of Colorado. The models show this to be the
main area of afternoon thunderstorm development. Of interest here
is that the HRRR has been trending toward the idea of
thunderstorms moving off the southern Front Range and forming into
a convective segment that dives southeast toward the OK/TX
Panhandles and possibly clipping far southwest Kansas later this
evening. As a result, will shift the highest chance pops into
that area tonight. There could be some lingering isolated to
widely scattered showers and thunderstorms lingering through the
remainder of tonight over southwest Kansas so will maintain at
least some low chance pops through Tuesday morning before
precipitation gradually diminishes.

Cloud cover will linger through much of the night, so will keep
overnight lows at or a few degrees above the warmer MAV guidance.
Tuesday should be similar to or slightly warmer than today,
temperature-wise.

.LONG TERM...(Tuesday night through Monday)
Issued at 301 PM CDT Mon Jul 23 2018

Tuesday night should be fairly quiet as any lingering daytime
showers will diminish quickly. Through the remainder of this week,
strong upper level high pressure, currently centered over New
Mexico, will slowly retrograde westward to over southern California
by Thursday night. As it does, stronger northwesterly flow around
the northeast quadrant of the upper high will slowly move south
toward the central Plains. This will bring increasing chances for
precipitation to western Kansas late in the week as thunderstorms
developing along the front range of northern Colorado and Wyoming
become organized into convective complexes that move out over
central and western Kansas mainly during the overnight hours. All
of the global models (GEM/GFS/ECMWF) are showing this although
timing and heavy precipitation tracks vary with the models.
Suffice it to say, likely chances for thunderstorms seem
reasonable later in the week, along with the potential for some
locally heavy rain and flash flooding. Temperatures should stay on
the cool side of normal through this period as well.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1223 PM CDT Mon Jul 23 2018

Scattered cumulus will increase through the early afternoon hours
with occasionally broken VFR cigs possible. Isolated showers and
thunderstorms could develop north of GCK later this afternoon but
confidence in any of these impacting the terminal is low. Late
afternoon thunderstorms developing off the Colorado Front Range
may make it into far southwest Kansas after 03z but it appears
this convective activity should stay southwest of the GCK/LBL
terminals, although outflow could result in winds becoming
westerly at 10-20 kts for a few hours.
