Area Forecast Discussion
National Weather Service Goodland KS
606 PM MDT THU JUN 23 2016

.SHORT TERM...(Today and tonight)
Issued at 249 AM MDT Thu Jun 23 2016

Ongoing early morning convective activity continues eastward
across southwest KS today along a frontal boundary that extends
eastward into western Missouri and is laid up along the front
range on the western side. Convective activity is expected to
reinitiates later today along the front range and frontal
boundary where moisture has pooled and the instability axis is
located. Scattered storms will move east across the region
overnight. The is currently a slight risk of severe storms over
east central Colorado extending into west central Kansas. The main
threat will be winds and large hail with some localized heavy
rainfall possibly producing some flash flooding during the evening
hours.

The stronger westerly flow aloft remains well north of the
forecast area, but several weaker short wave trough move east of
the Rockies and across the central high plains through the short
term period. These short waves are appearing as diurnally driven
convective feedback features in the models as each of them seem to
appear over the higher terrain late each afternoon and move east
over the plains states during the afternoon and overnight hours
as they weaken downstream. As a result, expect isolated to
scattered late afternoon and evening thunderstorms to move across
the forecast area again Friday and Saturday. Additionally a cold
front will move across the central high plains region during the
day on Saturday in advance of the upper low moving east of the
northern Rockies and across the northern high plains in the
vicinity of U.S./Canada border. This will provide a good focus for
afternoon storms on Saturday.

Temperatures are expected to be above normal with highs rising
well into the 90s again on Friday, and backing off somewhat into
the 80s and lower 90s again on Saturday with the passage of the
cold front.

.LONG TERM...(Friday night through Thursday)
Issued at 307 PM MDT Thu Jun 23 2016

Forecast issues will be chances of precipitation through the period
and high temperatures. Satellite showing an amplified flow across
the Pacific to along the west coast of North America. The flow
flattens out over the country with a broad ridge across the southern
portion and lesser ridging/nearly zonal flow over the northern
portion.

Models differ with details on shortwave troughs through the Friday
night through Sunday period. Models are suffering a lot from
convective feedback and am thinking that they are overdoing the
convection/qpf, especially from the end of Saturday night into
Sunday. In cases would like to have made some specific periods dry
but collaboration is keeping some kind of mention of thunderstorms
in the forecast through the entire period.

Friday night...Shortwave trough is near the western end of the later
at beginning of the period with surface convergence near or just
west. Problem is that 700 mb are plus 16 to 17. At this time will
confine a slight chance to the far west initially. Expect
thunderstorms to work their way east across the area as shortwave
moves across.

After midnight another shortwave trough moves at the same time the
front moves through. This looks to either redevelop precipitation or
keep it going through the rest of the night.

Saturday/Saturday night...There looks to be ongoing thunderstorms in
at the start of the morning. Question then becomes how much
thunderstorm activity will be around in afternoon and night. Right
rear quadrant of upper jet begins to affect the area in the
afternoon and continues into the evening hours. However, you would
think that the front and second shortwave should be pushing the
moisture and thunderstorms out of the area by mid to late afternoon.
At this time will keep something in the southeast half but am
thinking the models are overdoing the qpf.

Front will cool temperatures off about 5 to 10 degrees. Tended to
go toward the slightly cooler guidance.

Sunday...Was briefed that this period would be dry. However, a
number of minor waves, some convectively induced, look to
sporadically produce precipitation. Uncertainty and collaboration
have kept some kind of pops in here. My gut feeling this day will be
dry.

Sunday night through Thursday...Model disagreement starts at the
beginning of this period and gets worse with time. It involves the
system moving from south central into eastern Canada and the
resulting troughing over the eastern portion of the country. It also
involves how the models handle the troughiness along the west coast.

The handling or mishandling of these features affects the amplitude
and the position of the western ridge. This ridge moves west with
time and models typically have difficulty in retrogressing patterns.
Models last week also had trouble with a similar setup. No matter
which model you choose there looks to be numerous, hard time,
shortwave troughs moving through in this flow.

There looks to be waffling stationary boundary across the area
during this time and because of the differences aloft, they differ
on where they put this boundary. As a result the extended gave me
slight chance to chance pops. Give the pattern, the uncertainty, and
near impossibility of getting the details right at this time scale,
have no problem in keeping those pops with only cosmetic changes.
This period does have the potential to be active and wet. Also a
result of the uncertainty, left the temperatures alone as well.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 606 PM MDT Thu Jun 23 2016

VFR conditions should prevail at both KGLD and KMCK. Main
aviation concern will be convection in Colorado, and whether it
will impact either terminal. Exact evolution of this activity is
still uncertain based on models, however I was confident enough to
keep mention in both TAFs based on upstream radar trends. These
thunderstorms could be strong or severe if they impact either
terminal (hail/strong winds).
