...Aviation Update...

.DISCUSSION...(This evening through Monday)
Issued at 147 PM CDT Mon Oct 31 2022

Key Messages:

1. Continued warm with above normal temperatures through Thursday,
which gives near critical fire weather conditions some areas.

2. Dynamic weather system to impact the central/southern United
States starting late Thursday and into the weekend. A variety of
weather impacts are possible for the area, including the potential
for beneficial rain, isolated strong thunderstorms and maybe even
a few snowflakes. However, there is still plenty of uncertainty
with this weather system at this point.

Beautiful Halloween day today with temperatures around 70 degrees,
lots of sunshine and a light breeze. Those nice conditions will
extend into the evening as well even as we cool. We have had some
big swings (highs in the 70s/highs in the 40s) for Halloween the
past decade but this one will probably go down as the least spooky
Halloween weather in recent memory.

As for the rest of the forecast, we can break it down into two basic
parts: Roughly pre-cold front (Tonight-Thursday) and post-cold front
(Thursday evening through Monday).

Through Thursday, we are dry, until we introduce a small chance
for showers Thursday afternoon. Leading up to that, its very mild
with highs in the 70s, or possibly 80 degrees in north central
Kansas. Winds will increase from the south Tuesday and Wednesday
with 30 mph gusts on Wednesday over eastern areas Wednesday. Low
level moisture will ride the wind north and overspread the areas
with dewpoints in the 40s/50s by late Wednesday. It could feel a
touch humid for early November. While sunshine is expected the
next couple days, the push of low level moisture looks like it
result low clouds much of the day Thursday. So while it will be
mild, don't expect much sunshine Thursday.

The changes start coming late Thursday afternoon as a cold front
enters south central Nebraska from the northwest. Most model
timing has settled on some initial cooling in the northwest late
Thursday afternoon, then the main push of the front after dark
Thursday and clearing the forecast area by Friday morning. This is
one of the better chances from some decent rainfall across most
of the forecast area in a long time. Sufficient instability will
support some thunderstorms and a strong or isolated severe storm
is possible in the evening hours along the lines of SPC. Those
details will come with time with regard to fine tuning location
and possible impacts, as well as timing. But overall, the rainfall
potential Thursday evening could help our short-term fire
conditions significantly if it materializes. And while we do
have a few snow showers mentioned in the far northwest part of
the forecast area, it is really nothing of consequence at this
point.

There is more uncertainty Friday and Saturday with just how the
main upper system ejects from the southwest. A lot of the low
level moisture could get wrung out in the Southern Plains with
widespread thunderstorms both days. The wrap around precipitation
component of the storm may have trouble developing because of
this. While rain chances are in the forecast both days, they are
much lower in nature, generally ranging from 20 to 50%. Expect
changes with time to these numbers for sure.

Obviously we start cooling late Thursday and into the weekend, but
ensembles suggest the cooler trend will continue into the next week.
While this weekend we may very well manage to reach the 50s to
around 60, it looks potentially a whole notch colder in the 8 to
15 day timeframe (later next week) with highs below the normal of
middle 50s, giving a more appropriate mid-November feel to our
weather.

.AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Wednesday)
Issued at 1223 AM CDT Tue Nov 1 2022

VFR conditions are forecast through the period with increasing
southerly winds during the daytime hours...and a decent LLJ
expected to develop late Tuesday evening resulting in modest LLWS
at both terminals after about 02/03Z. As the pressure gradient
increases across the region and deep mixing is realized by
midday...expect steady southerly winds with gusts to around 20 KTS
to become likely for the latter half of the afternoon and into
evening hours. Then as winds begin to decouple tonight and the
pressure gradient strengthens further...a modest LLJ will result
in LLWS at both terminals...although surface winds will likely
remain somewhat breezy in the 12-15 KT range through the overnight
hours.

.FIRE WEATHER...
Issued at 147 PM CDT Mon Oct 31 2022

With high temperatures in the 70s to around 80 degrees and
increasing winds, fire weather become more of an issue for
the area given continued drought. Both Tuesday and Wednesday
afternoon could experience near critical fire weather conditions
in the late afternoon. RH values are lower Tuesday despite some
increase in low level moisture. Winds are up a bit, more steady
in the 15 to 20 mph with occasional gusts, but not in Red Flag
territory.

Winds increase more on Wednesday when it will just be windy over
much of the area, but so does low level moisture quite a bit as
dewpoints surge into the 40s/50s over the eastern 2/rids of the
area. Low RH values will be confined to the far west, and winds
may be a bit less there.

In the end, no fire related headlines due to low confidence in
meeting criteria, but still near critical conditions can be cause
for concern, especially if a fire does develop.
