.SHORT TERM...(This evening through Saturday)
Issued at 316 PM MDT Fri Jun 16 2023

Key Messages:

1) Severe thunderstorms possible across the southeast plains
into the evening, with potential supercells and large hail
along/north of the Highway 50 corridor from Pueblo to Lamar.

2) Flash Flood Watch in effect for southeast Colorado counties along
and north of highway 50 and along and east of I-25 until midnight.

3) Severe risk returns to the I-25 corridor and especially the
southeast plains on Saturday.

Currently, upper level wave lifting out of nrn NM into srn CO
evident on satellite imagery this afternoon, while at the surface
weak/diffuse frontal boundary was located along the Palmer Divide.
While convection has initially been a little slow to develop this
afternoon, radar as of 3 pm was indicating increasing upward motion
across the area with storm coverage beginning to ramp up.
Environment over much of the southeast plains looks favorable
for severe storms into the evening, with CAPE of 1000-1500 J/K and
0-6km shear approaching 50 kts along and east of I-25. Main concern
will be supercells with very large hail along the Highway 50
corridor, along with at least a low risk of tornado, though marginal
low level helicity and relatively high LCLs may limit tornado threat
somewhat. Heavy rainfall also possible with any convection, with
perhaps El Paso County most favored for flooding where soils are
saturated and repeat storms area possible. Bulk of the activity
moves east into Kansas around midnight, with any lingering showers
ending by early Saturday morning.

On Saturday, main upper level trough lifts eastward across the state
during the day, with strong upper forcing for precip over much of
the area. CAPE again rises into the 1000-2000 J/KG range along and
east of the mountains, while 0-6km shear is 40-50 kts.  Models hint
an an earlier onset of convection Sat, with storms clearing the I-25
corridor by 00z and exiting the eastern plains by around 03z. Only
real hindrance to convection would be potential development of
widespread stratus in the wake of Fri night convection, which would
limit amount of available instability, especially El Paso County
where low level upslope winds may keep clouds in longer. SWODY2
has slight risk back into eastern El Paso and Pueblo counties, which
looks reasonable, and supercells with very large hail will again
be possible. Max temps Sat again on the cooler side of average, with
most locations in the 60s/70s.

.LONG TERM...(Saturday night through Friday)
Issued at 316 PM MDT Fri Jun 16 2023

Key Messages:

1) Thunderstorms across the plains Saturday evening, with clearing
skies and cool conditons overnight for the region.

2) Drier and warmer conditions expected for the end of the weekend
and into early next week.

3) Uptick in precipitation for the later part of next week, with
warm temperatures continuing.

Saturday Night: A busy start to the Saturday evening is expected,
with conditions becoming more quiet overnight. Synoptically, a short
wave will being pushing across Colorado during this time. This
feature will have helped sparked thunderstorms closer to the I25
corridor earlier during the day. As this wave treks eastward,
thunderstorms will follow it during late afternoon to early evening
timeframes. Given the environment expected to be in place, with
better moisture, instability, and shear, these storms may be strong
to severe as they push across the far eastern plains and into
Kansas. With that all said, as the aforementioned wave starts to
exit the region by late evening, any precipitation across southern
Colorado is anticipated to dissipate and clearer skies are expected
to prevail for the rest of this period. With clearing skies and
calming winds anticipated, much of the area will cool efficiently.
Most of southern Colorado will fall to slightly below season values.

Sunday - Tuesday: For the end of the weekend and early part of next
week, a quieter set of days is expected weather wise. Ensemble model
guidance is in good agreement about building a ridge of high
pressure over the Colorado/central US during this period. As this
feature expands, synoptic subsidence will increase over the Colorado
region. This sinking air, along with decreasing moisture content,
are anticipated to keep the southern Colorado region much more dry.
The exception to this may be an isolated rain shower or thunderstorm
along the mountains given diurnal upslope patterns during the day.
In addition to drier conditions, a warming trend is expected for the
area. With the ridging in place, coupled with downsloping winds,
much of southern Colorado is expected to warm back to near average
values for this time of year.

Wednesday - Friday: For the later part of the mid-week period, an
uptick in active weather is anticipated for southern Colorado.
Ensemble model guidance remain in relatively good agreement about
the ridge partially beginning to break down as a trough starts
approaching from the west. In response to the approaching trough,
both moisture and lift will start to rise over the area. These
conditons will favor an increase in precipitation coverage across
southern Colorado. In addition to that, strong to severe storms will
possibly be a concern during this period, particularly across the
eastern plains, where model guidance is in solid agreement about a
dryline developing (though where this ultimately develops will play
a huge role on this concern). As for temperatures, not much change
is expected from the earlier part of the week. Much of southern
Colorado is anticipated to hover near average values for this time
of year.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 316 PM MDT Fri Jun 16 2023

Scattered to numerous showers and thunderstorms will move off the
higher terrain and across the adjacent plains through 02z-04z, with
vcts at both KCOS and KPUB. TEMPO tsra at both sites with local MVFR
to even brief IFR conditions in +TSRAGR possible along with
erratic gusty winds up to 50 kts under the stronger cores. Winds
will become northerly as thunderstorms move east of KCOS and KPUB
this evening and overnight. There is the potential for stratus and
possibly even fog at the KCOS and KPUB terminals if heavy rain falls
this afternoon, which could lead to a mix of MVFR and IFR conditions
Saturday morning. Confidence is still low at this point. On
Saturday, vcts returns to both KPUB and KCOS after 18z, with most
activity moving east of the terminals after 21z-22z.

At KALS, VFR the next 24 hrs, with occasionally gusty winds due to
distant convective outflows. May need a vcsh mention after 18z as
upper level low moves overhead.

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...Today and Tonight

Severe thunderstorms are likely today across all of the plains. In
addition to the severe weather threat, flash flooding will also be
possible, especially in the Pikes Peak region, and areas along and
north of highway 50.

Thunderstorms were developing over the higher terrain late this
morning. These storms will continue to intensify and push out onto
the plains by mid afternoon. Initially, the stronger storms will
affect Teller and northern El Paso county during the mid afternoon
time period, and then push south across all of the Pikes Peak
region late this afternoon and early evening.

Thunderstorms coverage is expected to become more widespread over
the remainder of the plains from very late this afternoon and
into the evening hours. Some of the storms may last into the
early morning hours over the far eastern plains.

Several of the thunderstorms later this afternoon and evening
will become strong to severe. Hail up to the size of golfballs,
wind gusts to 70 mph and isolated tornadoes will be possible.

In addition to the severe weather threat, heavy rain is also
likely today. Due to the saturated grounds, it will not take much
for flash flooding to occur, especially in and around the Pikes
Peak region.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Another round to strong to severe storms are expected over the
eastern plains on Saturday afternoon and evening. Damaging winds,
large hail and isolated tornadoes will be possible. Heavy rains
will once again be a threat, and flash flooding will be possible
over the region.

Warmer and drier weather remains in tap for Sunday into early
next week, with a return of afternoon storms across the plains
later next week. Much warmer temperatures will lead to another
surge in runoff from the last of the high mountain snowpack.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely over portions of the region.
