Area Forecast Discussion...CORRECTED
National Weather Service Pueblo CO
338 PM MDT Thu May 25 2023

.SHORT TERM...(This evening through Friday)
Issued at 320 PM MDT Thu May 25 2023

Key Messages:

1) Scattered storms this evening, a few severe storms possible
across the plains.

2) Another day with severe thunderstorms possible for the southeast
plains on Friday.

Currently, another day of weak shear (0-6km 20-30 kts) but strong
instability (CAPE of 1500-2500 J/KG) across the area, with
convection firing over the eastern mountains and along a weak
surface boundary (stretching from near TAD to just south of LHX) as
of mid-afternoon. Most CAMs move storms eastward from the higher
terrain across the plains this evening, though perhaps in a less
organized fashion as last night, as dynamic lift today is less
pronounced. Still a low end severe threat for most of the plains
into the evening, with HRRR suggesting some storms along the Palmer
Divide after sunset until close to midnight. Convection farther west
over the mountains and interior valleys has been weaker/more
isolated in nature, and expect most storms here to diminish this
evening. Will maintain high end sct pops for locations east of the
mountains until late evening, then taper precip chances off from
west to east toward midnight.

On Friday, upper level swly flow continues across CO, with perhaps a
subtle increase in mid/upper level winds by late day as jet streak
noses into the swrn part of the state. Over the eastern mountains
and plains, moist/unstable air mass will remain in place, leading to
another round of afternoon/evening thunderstorms, though orientation
of the upper jet suggests best dynamic forcing may shift north of
the Palmer Divide by evening. Again, 0-6km shear looks fairly weak,
in the 25-35 kt range, while instability by afternoon climbs into
the 1000-2000 J/KG range. Marginal risk of severe storms looks
warranted, though strongest storms may end up north of the Palmer if
lastest iteration of the NAM is correct. Farther west over the
mountains and interior valleys, air mass looks slightly drier,
leading to a downturn in convective strength and coverage, though
still at least isolated activity expected. Max temps will remain
little changed from the past couple days.

.LONG TERM...(Friday night through Thursday)
Issued at 320 PM MDT Thu May 25 2023

Key Messages:

1) Heightened chances for daily afternoon rain showers and
thunderstorms for southern Colorado into next week.

2) Near to above average temperatures expected for much of southern
Colorado into next week.

Saturday - Thursday... The weekend and into much of next week
will maintain a rather consistent, but active, weather pattern.
Both deterministic and ensemble model guidance are in strong
agreement about developing an overall, but messy, ridge pattern
across the central US, with broad and disorganized troughing to
the west. Colorado will be situated generally on the western
periphery of the ridging and eastern periphery of the troughing.
This pattern will allow for numerous weak short waves and ripples
in the flow to pass over the southern Colorado region. In addition
to that, given the broader troughing to the west, deeper moisture
is expected to stay further into Colorado, though exact moisture
quality will depend highly on how the waves and ripples in the
flow ultimately evolve. Given all of this, daily chances of
afternoon rain showers and thunderstorms are anticipated for the
southern Colorado area each day to some extent. Also, with the
moisture, and therefore instability, expected, along with modest
upticks in shear from the waves and ripples, some stronger storms
are possible across the area, but particularly across the eastern
plains, where moisture will be greatest. As for temperatures, a
more steady state of temperatures is anticipated given the ridging
and no major storm systems/cold fronts. This pattern is expected
to keep much of southern Colorado near to slightly above average
for this time of year.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 320 PM MDT Thu May 25 2023

VFR conditions at all terminals the next 24 hrs, though there will
be sct tsra across the area this evening, with storms most numerous
across the southeast plains. Will carry a vcsh at all terminals
until 01z-02z, and may upgrade to a vcts mention at KPUB 22z-02z,
and KCOS 22z-04z, as storms move off the mountains. Most activity
will diminish/shift east toward KS after 03-05z, though HRRR holds
onto some storms until 05z-07z over the higher terrain north of
KCOS. Very little change in the pattern for Friday, with a risk of
afternoon convection again at all terminals after 20z, and the
potential for severe storms around KCOS and KPUB 21z-00z.

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

.DAY ONE...This Afternoon and Tonight

Scattered thunderstorms will develop over the mountains early this
afternoon, then spread eastward into the adjacent plains late
this afternoon and evening. A few storms could become severe
across the southeast plains where hail up to around 1.5 inches in
diameter, wind gusts to around 60 mph, heavy rainfall and
dangerous cloud to ground lightning will be possible. Although the
risk looks low, a brief weak tornado can not be ruled out,
especially for the Palmer Divide and northern slopes of the Raton
Ridge. Heavy rainfall could cause localized flash flooding,
especially for areas with susceptible soil conditions.

Across the mountains today, the main risk with thunderstorms will be
brief heavy rainfall, small hail, gusty winds up to 50 mph, and
lightning.

Thunderstorms will decrease from west to east this evening with a
few thunderstorms lingering overnight near the Kansas border.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Strong to severe thunderstorms will be possible across southeast
Colorado on Friday, with the main risks from storms being strong
outflow winds and large hail. In addition, the threat of heavy
rainfall and possible flash flooding will continue on Friday.

Available moisture slowly decreases from west to east across the
region through the Memorial Day Holiday weekend. This will keep
daily chances of higher based isolated to scattered afternoon and
evening showers and storms over and near the higher terrain. These
storms will produce more wind than rain, with the continued threat
of cloud to ground lightning. Further east across the far southeast
Plains, low level moisture will remain in place, bringing the threat
of a few stronger storms producing hail and locally heavy rainfall.

As temperatures warm through the Holiday weekend, high and fast
flows can be expected across area rivers and streams, especially
across the eastern San Juan mountains and into the San Luis Valley,
as the high mountain snowpack continues to melt.

.SPOTTER INFORMATION STATEMENT...

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