Area Forecast Discussion
National Weather Service Pueblo CO
311 PM MDT Fri May 26 2023

.SHORT TERM...(This evening through Saturday)
Issued at 239 PM MDT Fri May 26 2023

Key Message:

1) Strong to severe thunderstorm risk continues through the evening
tonight. A conditional risk for severe weather returns tomorrow
afternoon with 1" hail and 60 mph wind gusts possible over the far
eastern plains during the late afternoon.

Meteorological Discussion:

An upper level trough remains over the Great Basin at the beginning
of the short term forecast period and is expected to propagate to
the east throughout the rest of the period. The trough, combined
with low level moisture from the Gulf of Mexico, will aid in
thunderstorm development this evening and once again tomorrow
afternoon. Tonight, as the thunderstorms that have currently
developed over the mountains and I-25 corridor move to the east,
they'll run into an environment that will be more conducive to
strong thunderstorm outflows, especially since storm mode is
expected to turn into a line of thunderstorms. DCAPE values over the
eastern plains expected to be around 800 to 1000 J/kg due to dry
midlevels. As they reach Bent, eastern Las Animas, Otero, and
western Kiowa County at around 6PM, there should be around 1000-1500
J/kg of SBCAPE over that region, so the severe hail risk will still
be in play. However, after sunset, when the line of storms reaches
the far eastern plain, there will be a fair amount of inhibition set-
up over eastern Kiowa, Prowers, and Baca County, which will limit
the severe risk. So overall, main risks earlier will be 1 to 1.5"
hail, 60 to 70 mph wind gusts, and perhaps an isolated tornado on
the leading edge of the line of storms. Later on tonight, after 8PM,
the main risk turns into more of a wind risk of 50 to 60 MPH with
again, a very low chance of brief spin up on the leading edge of the
line of storms. By midnight, thunderstorms will either have
dissipated or will have pushed out of our forecast responsibility
and into Kansas.

Tomorrow looks pretty similar to today, but will have stronger
forcing since a negatively tilted will pass overhead. The moisture
tap over the eastern plains will remain, which puts around 1200 to
1800 J/kg of MUCAPE and around 40kts of 0-6km of Bulk Shear over the
far eastern plains. HOWEVER, there the chance for a bit more CIN
over the far eastern plains with a low level inversion set-up. It'll
be truly a conditional severe risk tomorrow. The NAM is more excited
about the severe risk, the GFS keeps us too stable even keeping
storms primarily over Kansas, and the ECMWF looks similar to the
GFS, but a bit further to the west, impacting our far eastern
plains. Again, it'll be conditional, if we can break any sort of
inhibition, there will be chance for 1.5" hail and 70 mph wind gusts
across the I-25 corridor east, however the most likely outcome will
be 1.0" hail and 60 mph over the far eastern plains later in the
day, around 4 to 8 PM.

Otherwise, high temperatures tomorrow will be in the mid to upper
80s over the majority of the plains and in the 70s over Baca County,
whereas the mountain valleys will be in the 70s.

.LONG TERM...(Saturday night through Friday)
Issued at 239 PM MDT Fri May 26 2023

Key Messages:

1) Drier/warmer much of the area Sat/Sun, still a risk of strong
storms over the southeast plains.

2) Moisture returns next week from Tue onward, with increasing
thunderstorm chances for the region.

Weak upper ridge builds slightly over the area on Sunday, as new
energy carves out another trough along the California Coast.
Resulting w-sw flow across srn Colorado should continue to keep
deepest moisture/instability shunted east across the plains, with
dryline somewhere near a Limon/La Junta/Kim line by Sun afternoon.
Still a risk of strong/severe storms over the far east ahead of
the dryline, while farther west, only isolated/weak/high based
convection is expected. Given building heights/mid levels temps,
maxes Sunday look warm, with most lower elevations into the 80s.

Low/mid level flow begins to turn back more s-se on Mon, leading
to a gradual westward spread of moisture toward the I-25 corridor
by afternoon. As a result, expect a modest uptick in convection
from the southeast mountains eastward across the plains, though
rather shallow nature of initial moisture surge suggests storm
strength/coverage may be lacking. Better moisture returns to the
region from Tue through much of the week, as western U.S. upper
trough begins to work slowly eastward and s-se low level flow
persists over ern CO. Still a lot of details to work out on
location/strength/timing of convection, though general model trend
toward wetter/slightly cooler weather has been consistent over
the past few days.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 239 PM MDT Fri May 26 2023

Thunderstorm chances bring the potential for MVFR to LIFR conditions
this evening over KALS, KCOS, and KPUB, but by after 0300Z tonight,
thunderstorm chances will dissipate leading to VFR conditions. The
VFR conditions are expected to continue throughout the rest of the
forecast period for all sites. Southwesterly winds are expected over
KALS tomorrow with wind gusts up to 25 - 30 MPH during the
afternoon. KCOS and KPUB will experience winds from the south-
southeast tomorrow afternoon with gusts up to 25- 30 mph.

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

.DAY ONE...Today and Tonight

A few severe thunderstorm are expected this afternoon, especially
along the I-25 corridor region, from Walsenburg northward to the
Palmer Divide. The primary severe weather threat will be large
hail up to the size of golfballs. The greatest threat of severe
weather over the I-25 corridor region will be from 2 pm to 6 pm
this afternoon.

Thunderstorms are expected to develop around the Walsenburg area
around 2 pm this afternoon and move quickly north-northeast along
the I-25 corridor. Additional storms will also develop along the
Wet Mountains and move north-northeast. Thunderstorms will have
the potential to affect all of the major population centers along
the greater I-25 corridor region, including Pueblo, Canon City and
all of the Colorado Springs metropolitan areas.

Later this afternoon and evening, scattered thunderstorms will
develop across the remainder of the plains, and these storms will
be capable of hail up to one inch in diameter and wind gusts to 60
mph.

Several late night thunderstorms may be possible over the plains
tonight as another disturbance pushes out over the plains during
the early morning hours. These storms are not expected to be
severe.

Thunderstorm activity over the interior mountains will be less
today due to drier air moving into the Continental Divide region.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Strong to severe thunderstorms will be possible across southeast
Colorado on Saturday, 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 Saturday.

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 and especially along the eastern border, low
level moisture will increase 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 due to
melting snowpack, especially across the eastern San Juan mountains
and into the San Luis Valley.

.SPOTTER INFORMATION STATEMENT...

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