.SHORT TERM...(Today and tonight)
Issued at 325 AM MDT Sun Jun 11 2023

Key messages:

1) Strong to severe thunderstorms across the easter plains, along
and east of the I-25 corridor, this afternoon and evening. Large
hail and damaging winds are the main hazards, though a low end
tornado risk is possible across the eastern plains this evening.

2) Heavy rainfall will be possible with any thunderstorm this
afternoon into this evening. The risk for torrential rainfall and at
least localized flash flooding increases across the plains late this
evening into early Monday morning.

Overall, relatively quiet early this morning across the area, though
departing mid level vort is assisting with some isolated showers and
thunderstorms over the far southeast plains. Don't anticipate this
to persist for too much longer, with a drying trend anticipated for
the remainder of the early morning hours. The mid level cloud cover
in place over the plains should scatter this morning, with partly
cloudy to sunny skies expected to start the day. The front which
moved into the area last evening continues to slowly sag south
across the plains, though no real big differences are noted post
FROPA at this time. There are some lower ceilings upstream across
northeast Colorado and northwest Kansas, and this could continue
south into the far northern portions of the area later this morning.
If so, think the farthest southward extent would be the Palmer
Divide east into Kiowa county. Any low ceilings should also quickly
scatter during the morning hours. The arrival of the cooler air mass
will provide cooler high temps today, with 70s high temps expected
for most areas today. Despite this cooler air mass, thunderstorm
chances look to remain high today given increases in available
moisture and a trend back towards deeper moist easterly flow.

As noted with previous forecasts, some weak riding aloft is expected
this morning. These rising heights along with some expected capping
should help to provide some slight delay in shower and thunderstorm
development today. By early to mid afternoon, however, approaching
mid level energy and increasing flow move overhead. This will help
bring a return to developing precip over and near the higher terrain
during that time. Easterly surface flow will be in place during that
time, though the 700mb flow will remain rather weak and unorganized.
This does change especially moving into the mid afternoon time
frame, with a steadier easterly 700mb wind developing, and deeper
moist upslope flow setting up. Will see thunderstorm activity
quickly increasing during that time with thunderstorm development
moving east off the higher terrain and into the I-25 corridor during
the mid to late afternoon time frame.

Daytime heating along with increases in available moisture will
support higher CAPE today and while there is some variability among
guidance as to the extent of the values, think an average of 750-
1500 j/kg will be in place over the plains by this afternoon. Do
think guidance, which is showing at least pockets of values near or
slightly higher than 2000 j/kg, could be onto something especially
as mid to potentially upper 50s dewpoints will be in place.
Increases in mid level flow, while a steady easterly surface wind
persists, will support increases in bulk shear today. Overall,
values of 35-45 kt seem reasonable, but do think areas of higher
values are definitely possible. All of this will support the risk of
strong to severe storms over much of the plains, along and east of
the I-25 corridor, this afternoon into the evening hours. With the
expected instability and shear and the likelihood of organized
development, think hail to the size of ping pongs and wind gusts up
to 70 mph will be possible with the strongest storms. I think a few
storms capable of producing hail to two inches could also occur in
this setup.

By early this evening, the risk of strong to severe storms will
continue into the eastern plains. The main hazards will continue to
be the large hail and damaging winds, however, guidance is fairly
consistent with additional increases in low/mid level flow this
evening. While the risk for tornadic development is generally low
today, this trend in the evening could support a low end tornado
risk over the eastern plains during the evening hours. Confidence is
somewhat low, but will be keeping a close eye on trends throughout
the day.

Last, any thunderstorm today into the evening will have the
potential to produce heavy rainfall. While can't completely rule out
the risk of localized flash flooding even across the burn scars,
faster storm motions today should help to limit this risk. That
being said, am keeping a close eye on the possible evolution into a
more widespread flash flood threat across the plains later this
evening into the early morning hours on Monday. Confidence is once
again somewhat low on this trend, but guidance is really beginning
to show the possibility of additional persistent ascent in a highly
unstable environment. If this were to occur, could easily locations
observe repeated rounds of potentially torrential rainfall tonight
and at least localized flash flooding. Think the risk will once
again be across the plains from the I-25 corridor eastward. Did
debate issuing a Flash Flood Watch for El Paso county, where the
risk/impacts could be the highest, but have held off at this time
and will let the day shift take another look at this possibility.

.LONG TERM...(Monday through Saturday)
Issued at 325 AM MDT Sun Jun 11 2023

Overall, there is decent agreement between the operational models
through much of the work week, with difference by next weekend. It
looks like we will transition from a wet period into drier, warmer
conditions by mid week. Ensembles support this scenario, and lean
towards the ECMWF and Canadian by next weekend.

Monday and Tuesday...a baggy upper low is forecast to slowly eject
across Colorado into western Kansas through Tuesday. The main
concerns during this period will be the potential for strong to
severe thunderstorms across the Plains on both Monday and Tuesday.

Lead energy is forecast to lift across the Eastern Plains Monday
morning, with scattered showers and thunderstorms ongoing. Not
anticipating any severe storms during the morning hours, but areas
of heavy rainfall will be possible, especially along and north of
Highway 50 over Bent, Prowers and Kiowa Counties. This activity
will shift east into Kansas by midday.

Back west, over the Eastern Mountains and I-25 corridor, clearing
should occur, and heating through the morning and early afternoon
will lead to destabilization and thunderstorm development. SBCAPE
values near 1500 j/kg and shear values around 30 kts will help
storms become strong to severe. Areas over the Palmer Divide,
south along the I-25 corridor will see the highest strong to
severe storm potential. This thunderstorm activity will shift east
across the Plains through the evening hours, exiting into Kansas
overnight. Wind gusts in excess of 50 mph, hail to near 1 inch in
diameter and heavy rainfall will be the main storm risks. Flash
flooding may be possible on area burn scars over the Mountains,
and in areas that have seen recent heavy rains.

Tuesday will be a challenging day, and much will depend on morning
cloud cover and how quickly it will erode away. If cloud cover
lingers, destabilization will be limited. The baggy upper system
is forecast to be over western Kansas by morning, with a vort lobe
dropping south through the afternoon. If skies clear and
destabilization is maximized, strong to severe thunderstorms will
once again be possible. At this time, storm development looks most
favorable over the Palmer Divide, south along the I-25 corridor.
Storms look to track southeast through the late afternoon and
evening. The strongest cells will be capable of strong winds and
large hail. Locally heavy rainfall will once again be possible,
with flash flooding over burn scars and saturated areas of
concern.

Temperatures will be cool both Monday and Tuesday, with areas on
the Plains seeing highs in the 70s.

Wednesday into Friday...as the upper system shifts east and
weakens, high pressure will build across the Desert Southwest.
This will put westerly zonal flow over Colorado. PWAT values are
forecast to fall across the region to near half an inch. This
drier air will limit shower and thunderstorm activity through mid
week. That being said, isolated activity will be possible over the
Central Mountains, east into the Palmer Divide region. Not
anticipating any severe weather or flash flood potential at this
time. Temperatures will also warm, with the Plains reaching the
mid 80s to lower 90s through the end of the week.

Next weekend...much will depend on when the next upper system is
forecast to eject out of southern California, northeast across
the area. The GFS is rather fast, dropping a strong storm system
south out of the Pacific Northwest, and ejecting the southern
California system across Colorado over the weekend. This would
likely bring an uptick on precipitation chances. The ECMWF and
Canadian solutions are much slower, with drier, southwest flow
across Colorado into early next week. Ensembles tend to support
this drier solution.  Mozley

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1127 AM MDT Sun Jun 11 2023

VRB conditions are expected to prevail for KALS throughout the
forecast period, and for KCOS and KPUB throughout the first half of
the forecast period, but then become IFR and possibly LIFR after 05Z
at KCOS and KPUB due to low CIGs and VIS in -SHRA/BR. SHRA and TSRA
are expected to be in and around the vicinity of KCOS and KPUB, and
possibly in the vicinity of KALS later in the afternoon and evening
today. If SHRA/TSRA does move over station, it could temporarily
lower CIGs and reduce VIS to MVFR/IFR criteria, or possibly even
LIFR criteria in +SHRA/+TSRA. It could also result in periodic
windshifts and increased wind speeds at for all terminals due to
outflows. There is also higher confidence of possible severe
strength outflow winds in the vicinity of both KCOS and KPUB later
this afternoon/evening, mainly after 21Z and until 05Z at KCOS and
after 22Z until 05Z at KPUB. Winds will be mainly synoptically
driven at KCOS and KPUB, except when influenced by vicinity
SHRA/TSRA, and more diurnally influenced for KALS. There is also low
confidence of possible FG/BR occurring at either KALS or KCOS during
the early morning hours, around 10 to 14Z. Given the low confidence,
it has been left out of both TAFs at this time.
