Area Forecast Discussion
National Weather Service Pueblo CO
252 PM MDT Sat Jul 29 2023

.SHORT TERM...(This evening through Sunday)
Issued at 250 PM MDT Sat Jul 29 2023

Key Messages:

1) Scattered thunderstorms persist this evening, with the strongest
storms expected along and north of Highway 50.

2) Above normal temperatures to continue.

3) Another round of showers and thunderstorms forming over the
mountains by midday Sunday, with the main risks being gusty winds
and locally heavy rainfall.

Currently...The upper ridge of high pressure continues over the
region, while at the surface east to southeast flow has allowed
dewpoints in the 50s and 60s to push into the eastern plains up to
the I-25 Corridor. Convection fired up over the higher terrain by
noon and storm movement has been very slow, with localized heavy
rainfall indicated by radar. Temps as of 2 PM have climbed into the
80s for high valleys and El Paso County, and into the 90s for the
remainder of the plains.

Tonight...Hi-res models are indicating 2000-2500 j/kg of CAPE across
the eastern plains this afternoon, with the highest concentration
roughly along and north of Highway 50, correlating well with the SPC
Marginal and Slight areas for severe wx risk. Bulk shear is weak, so
most probable threat concerns will be large hail up to 1.5 inches,
strong wind gusts in excess of 60 mph and periods of heavy rain.
Even though the focus area stays more northerly, all of the plains
and higher terrain will need to be watched since all of this llvl
moisture banked up against the eastern slopes is providing plenty of
fuel for efficient rainfall, which could lead to flash flooding
problems for area burn scars.

Models also show that the risk quickly moves east across the
plains right around 9 PM as the upper shortwave pushes towards KS
and NE. Therefore, definitely a severe wx risk through the early
evening, with conditions quickly calming after 9 PM until midnight.
Overnight low temps are forecast to be similar to previous nights,
with readings in the upper 40s to lower 50s for the high valleys,
and 60s across the plains.

Tomorrow...The upper pattern changes ever so slightly for tomorrow
as the high centroid starts to push east. Overall, Sunday should
feel like a repeat though with more of a focus of storm activity
tied to the higher terrain. So, plan on quick heating through the
morning, giving way to showers and thunderstorms developing over the
higher terrain between 11 AM and noon. SPC has the area under a
general thunder outlook, but the main threats anticipated are once
again strong wind gusts and periods of heavy rainfall which could
lead to localized flash flooding. Afternoon high temps will remain
about 5 degrees above seasonal normals, so look for highs in the
upper 80s to lower 90s for the high valleys, and 90s to near 100F
for the plains.

As a reminder, multiple days of showers and storms equates to an
increasing concern for area burn scars, which will need to be
monitored for the potential of flash flooding. Moore

.LONG TERM...(Sunday night through Saturday)
Issued at 250 PM MDT Sat Jul 29 2023

Key messages:

1) Showers and thunderstorms will continue throughout Sunday
evening, mainly over the higher terrain and I-25 corridor. Some of
the storms could be strong to severe along and east of the I-25
corridor in El Paso and Pueblo counties, with 60 to 70 mph wind
gusts and hail of 1 inch or greater in diameter.

2) Afternoon and evening thunderstorms will be more confined over
the mountains from Monday through Tuesday, and drier over the
eastern plains.

3) Afternoon and evening thunderstorms will have more widespread
coverage next Wednesday through Friday with a better chance of
precip over the plains, and some of the storms will likely become
severe over the plains.

4) Overall temperature trend will be remain above the seasonal
average through the mid part of next week, then there will begin a
cooling trend thereafter by the end of next week.

Detailed discussion:

Sunday night...

CAMs have been showing some inconsistencies with regards to the
convection for tomorrow evening. The NAMNest and the NSSL are the
drier model runs with hardly any convection over the plains, whereas
the HRRR and ARW show a much more significant amount of convection
over the plains, even continuing into the early morning hours of
Monday. Given the very weak shear in place, along with the mid-level
flow primarily being out of the south over the plains, it is
probably more likely that there will be less in the way of activity
across the plains. That being said, if the HRRR/ARW verifies, there
could be a developing line of thunderstorms that extends from El
Paso County down to Huerfano County around 8 PM, and this will move
eastward and off over the eastern plains by later in the evening.
There will be some increasing shear by later on around 25 kts and
MUCAPE of more than 1500 J/kg in some areas, so there could be a
stronger to severe storm that develops along this line. If a severe
storm does materialize, it will likely be mainly a strong wind
producer of 60 to 70 mph. Although there will also be enough
instability in place for updraft strengthening and hail of possibly
1 inch or greater in diameter. As the evening progresses, things
should continue to stabilize and become more capped in the PBL, and
storms should begin to weaken and dissipate by around 1 to 2 AM.
There could still be some showers and maybe an isolated storm
continuing over the higher terrain through the morning on Monday.

Skies will subsequently begin to clear for most areas, except for
the southwestern mountains, but it will still be warmer than average
temperatures overnight with lows in the mid to upper 60s over the
plains and generally in the upper 40s to mid 50s for high country.

Monday through Tuesday...

The ridge will remain centered and nearly quasi-stationary over
Oklahoma throughout this period in the forecast. This will keep the
monsoonal moisture plume along with development of afternoon and
evening thunderstorms more confined to the mountains with the mid
level flow being more southerly rather than westerly. There could be
a few storms that make it out into the adjacent plains but the
majority of the plains, and especially the eastern plains, should
remain mostly dry through Tuesday. Temperatures will remain above
average, with only a very slight cooldown through this period,
although some areas of the plains will still likely hit the 100
degree mark.

Wednesday through Friday...

On Wednesday, deterministic models are continuing to resolve the
progression of an upper level low propagating northeastward from off
the coast of southern California towards the great basin and
eventually to the north of the region as it becomes absorbed into
the building ridge over the western states. This will help influence
and increase the amount of thunderstorm coverage over the region,
especially over the plains as the mid-level flow transitions back to
being more westerly. PWAT values with ensembles have been
consistently displaying an uptick in precip over the plains as they
have in previous days. In addition, increasing shear over the region
will also allow for there to be the potential of storms becoming
severe, especially over the plains on Thursday and Friday as there
will be an increasing southeasterly flow advecting up higher
dewpoints. This approaching trough will also help to cool
temperatures back to around the seasonal average by Thursday, and
even cooler with below seasonal temps on Friday. It will be slightly
cooler over the higher terrain on Wednesday as well, yet the
downsloping southwesterly winds will keep the lower valleys and
plains relatively warmer on Wednesday.  -Stewey

Generally VFR conditions anticipated for much of the forecast area
over the next 24 hours, including the three main TAF sites of KCOS,
KPUB and KALS.

Convection over the higher terrain this afternoon is expected to
affect mainly KCOS and KPUB into the eve so maintained mention of TS
in TEMPO group to roughly 03z, along with mention of potential winds
gusts to 30 kts. Intermittent MVFR vsby until 03z.

Thunder is less likely to move across KALS, though mentioned VCSH
