.SHORT TERM...(This afternoon through Saturday)
Issued at 111 PM CDT Fri Jul 16 2021

A mostly quiet weather night is expected across the FA. The main exception
to this is across Hamilton and Kearny counties, perhaps up to Scott
county and points southward. There will be a chance of mid evening
storms in this area. Storms are expected to develop along the higher
terrain of eastern Colorado and then slowly propagate to the south
or perhaps south-southeast. Bulk shear is slightly stronger today around
30-35 kt. The main threats with the storms will be damaging convective
outflows of 60-70 mph and heavy rainfall. Perhaps some hail too with
the slightly stronger shear that is in place. Have the highest pops
during the evening across Hamilton and Kearny counties to account for
this anticipated storm evolution. It should be a mid to late evening
event, so prior to 6 or 7 pm, much of the FA should remain storm free.
Since anticipated storm motion is to the S or SSE, much of the rest
of the area should be in the clear. There was a secondary concern of
storms forming across the Nebraska panhandle and then drifting towards
central Kansas, however, confidence on this actually occurring is low.

Otherwise, the rest of the forecast is ho-hum weather. Overnight lows
look to be seasonal with values mainly in the 60s.

For Saturday, a mid level ridge starts to amplify across the Central
Rockies. The net result is even weaker flow at the mid and upper levels
of the atmosphere. PWATs will continue to remain over an inch, so there
will be moisture and instability in place for storms. Confidence on
exact placement of storms in the weak flow regime is low. As a result,
have broad brush pops across the FA. Activity should remain isolated
to widely scattered, so there is a higher chance you'll remain dry
than seeing a storm over you.

Otherwise, near normal highs are expected with values in the 90s.

.LONG TERM...(Saturday night through Thursday)
Issued at 111 PM CDT Fri Jul 16 2021

The center of the mid level ridge on Sunday starts to head north during
the day. This may help us with a slightly higher areal coverage of
storms. The slight chance to chance pops looks reasonable for now.
Temperatures will continue to remain near or perhaps a few degrees
below normal to close out the weekend. It will still be warm nonetheless.

For Monday, the mean center of the mid level ridge is still expected
to be northwest of the FA. Again, a similar weather pattern is expected
to continue with warm temperatures and isolated storms.

As the ridge heads north, low level northeastern flow may develop on
the eastern side of the ridge. This may help to keep temperatures more
in the 80s versus the 90s for Monday through Wednesday. The main caveat
to this is the intense July Sun, which could offset this cooler low
level flow. Regardless if its in the 80s or the 90s, the end result
is still the same with the Summer weather continuing for the rest of
the extended period.

There still is a trend in the long range models to shift the ridge closer
to our area by the end of the business week. This could result in dry
conditions and seasonally hot highs dominating.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 606 PM CDT Fri Jul 16 2021

The challenge for the overnight is where the opportunity exists for
convection. The forecast area is downstream from ongoing surface
based convection over eastern Colorado. The atmosphere  will decouple
with time this evening however steep mid level lapse rates and
instability should support several model solutions which allow
clusters of thunderstorms to continue southeast across the heart of
west central and southwest Kansas. This shouldn't offer much of a
severe threat but rather locally moderate to heavy rains and
frequent lightning. Hopefully The 00 model runs will offer more
clarity for the convection late this evening and overnight as the
HRRR at this time is at odds on location with everything else.
