...UPDATED AVIATION DISCUSSION...

.SYNOPSIS...
Issued at 328 PM CDT Tue Jul 25 2023

Key Messages:

- Severe weather chances this afternoon and evening hinge around
  isolated to perhaps scattered storms forming across swrn and
  ncntl Nebraska. Storm development is uncertain.

- Additional isolated severe storms are possible Wednesday across
  much of wrn and ncntl Nebraska.

- Storms will be capable of locally heavy rainfall which may cause
  flooding in some areas.

- Heat advisory conditions are possible Thursday and Friday.

.SHORT TERM...(This evening through Wednesday night)
Issued at 328 PM CDT Tue Jul 25 2023

The remnants of a MCV is moving through wrn Nebraska this afternoon.
If this weak trigger is strong enough to break the 14C-15C cap at
h700mb, 5000-7000 J/KG of MUCAPE (3000-4000 MLCAPE) could be
released. The focus is a weak sfc trof, east of highway 83 drifting
toward cntl Nebraska.

Despite the trigger and instability, the models are mostly silent
with storm development. The forecast leans on the most aggressive
models like the NAMnest and HRRR which suggest isolated to low-end
scattered coverage late this afternoon and this evening. Damaging
wind gusts, large hail and locally heavy rainfall are the hazards.
PWAT will increase to 1.40 inches south and higher across northern
Nebraska.

Whatever storms develop should move east and southeast this evening
and exit by about 05z.

The next storm chance develops Wednesday afternoon and evening. In
the wake of the storm system tonight, a fairly strong outflow
boundary from the storms across the Dakotas should sweep into wrn
and ncntl Nebraska dropping dew points into the 60s. By late
afternoon, south winds should be underway across wrn Nebraska
causing the atmosphere to become unstable. The focus once again, is
a sfc trof aligned from southwest Nebraska northeast into ncntl
Nebraska. The dynamics, or upper level support are nebulous, perhaps
an UA disturbance across srn CA/NV this afternoon. POPs for this
potential event are limited to 30 percent for this reason. Still,
the NAMnest shows storms forming. In fact, the model shows more
storm coverage Wednesday than Tuesday.

Overall, it is worth noting several important ingredients for storm
development will remain over Nebraska. The region will remain under
a plume of subtropical upper level moisture, winds aloft will remain
strong and low level moisture will be focused and plentiful.

The forecast concludes the expected outflow boundary tonight will be
sufficient to lower temperatures and dew points. No Heat advisory is
planned for Wednesday.

.LONG TERM...(Thursday through Tuesday)
Issued at 328 PM CDT Tue Jul 25 2023

There is not much change in the extended forecast philosophy.
Wrn and ncntl Nebraska will remain under a plume of subtropical
moisture operating around the periphery of a strong upper level
ridge of high pressure located over NM. The ridge will slowly
migrate east into the srn Plains this week and next. Isolated to low-
end scattered POPs are in place during the next 7 days. Moisture
will be plentiful during this time but rain chance will be dependent
upon upper level forcing. A strong cap will be in place through
Friday which could certainly limit rain chances.

The model consensus suggests modest cooling will occur Saturday and
perhaps last into Sunday before the onset of another heat wave
Monday and beyond. The heat wave next week is the result of the
upper level ridge migrating east into the srn Plains and a long wave
trof impinging upon srn CA. This could flush a fresh batch of hot
air across the Rockies and into Nebraska.

Between now and Friday, Heat advisory conditions are contingent on
the dew point forecast. Thus far, forecast skill in handling the
70F+ dew points has been poor. If dew points continue to rise into
the 70s, heat advisories would likely be needed daily. The strong
cap in place during this time could certainly trap moisture
presenting ultra humid weather to the region.

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 624 PM CDT Tue Jul 25 2023

VFR conditions are expected to prevail this forecast period,
although with the caveat of the challenging convective portion of
the forecast.

A very unstable airmass remains in place east of a line from
Valentine to North Platte. As such, if any larger scale forcing
mechanism can force strong enough convergence on any surface
boundaries left behind from previous convection, isolated strong
to severe storms would develop. This would most likely affect the
KLBF TAF site from 01-04Z, but confidence in this occurring is low
due to a lack of shear and very warm temperatures aloft. Therefore
it has been left out of the forecast at this time.
