Area Forecast Discussion
National Weather Service Pueblo CO
1112 AM MDT Wed May 31 2023

.SHORT TERM...(Today and tonight)
Issued at 355 AM MDT Wed May 31 2023

Key Messages:

1) Strong to severe storms are likely across our plains this
afternoon and this evening, with all modes of severe possible,
especially for the far southeastern plains.

2) For the high country, scattered to numerous showers and
thunderstorms are expected today, with heavy rain and gusty winds as
primary risks for higher elevations.

Currently..

Water vapor imagery shows a low pressure system over southern
California, beginning to make its way into southern Nevada. Moist
southwesterly flow aloft is increasing overhead, as the low
continues to advance slowly eastward. Lingering convection over our
far southeastern plains has mostly diminished, though a few
lightning strikes have been noted this hour. Light showers over the
area should continue to push southeastward this morning, with cloud
cover increasing elsewhere. Dewpoints are high, as multiple outflows
have worked their way across the plains and into the terrain
overnight, which should help to set the stage for today's convection.

Rest of Today..

With abundant moisture working its way into the region under deep
southwesterly flow, expecting both more coverage and higher
intensity with today's thunderstorm activity. High res model
guidance continues to show an early start for convection, especially
over portions of our eastern mountains and mountain adjacent plains.
This area is starting out the day with lingering moisture and cloud
cover, so depending on how early we manage to get some clearing, we
could see storms developing as early as noon. The NAM 3k has over
2000 J/kg of CAPE and 1300 J/kg of DCAPE through portions of Pueblo
and Huerfano counties at that time, which could mean an early start
to severe winds across portions of our central plains. Better
chances for all modes of severe will exist across our southern and
southeastern plains later in the afternoon, where nearly 3000 J/kg
of CAPE is forecast to be available, along with at least 25 to 35kt
of bulk shear. SPC has portions of Las Animas and Baca counties
under a slight risk for severe thunderstorms this afternoon and this
evening. Primary risks will be large hail and severe winds, though
there will be risk for tornadoes and landspouts as well, especially
along any outflow or moisture boundaries that manage to setup later
in the afternoon and evening.

Another risk with today's convection will be the potential for
torrential rainfall, especially for urban areas, burn scars, and
areas that are still saturated from Tuesday's activity. PWATs are
over 150% of normal this afternoon, when our region will also fall
under the most favorable area of diffluence aloft. The WPC has our
southeastern plains under a slight risk for excessive rainfall, with
a mention of potential rainfall rates in excess of 1.5 inches per
hour. The rest of our plains, to include the I-25 corridor, along
with the eastern mountains and portions of Teller county, also fall
under a marginal risk for excessive rainfall today.

Tonight..

Showers and thunderstorms begin to clear from northwest to
southeast, with our central mountains clearing soon after sunset and
our southeastern plains potentially holding on to showers and weak
storms through the early morning hours of tomorrow. Overnight lows
stay mild, under mostly cloudy skies.

.LONG TERM...(Thursday through Tuesday)
Issued at 355 AM MDT Wed May 31 2023

Key messages:

1) Chance for severe thunderstorms across the far southeast corner
of the state on Thursday, with widespread showers and thunderstorms
elsewhere. Daily chance for rain and storms through the extended
period.

2) Potential for excessive rainfall each day over the weekend and
into the next week.

Thursday...The upper low tracks over the Four Corners during the
morning as it starts to weaken and fill in, then slides up into WY
as a secondary low or piece of energy moves into AZ. Convection will
linger through the morning due to decent bulk shear of 35-40 kts and
available llvl moisture, then become widespread through the
afternoon and evening with heating and increasing CAPE. The best
CAPE, around 2500 j/kg, will be found over the southeast corner of
the state, where SPC has drawn a Marginal area for severe
thunderstorm potential. The remainder of the plains is forecast to
develop around 1500 j/kg of CAPE so widespread convection is
anticipated, and WPC has also included a Marginal area for excessive
rainfall over the southeast corner as well as for the higher terrain
and northwestern CO. Temps are forecast to be slightly cooler, with
highs in the mid 60s to lower 70s for the high valleys, and 70s to
around 80F for the plains.

Friday through Sunday...A large, ill-defined area of low pressure
will park over the Intermountain West and Great Basin over the
weekend, allowing a weak but persistent easterly flow to develop
across the region. This will mean a daily chance of widespread
showers and thunderstorms, though severe thunderstorms are not
expected at this time. Instead, excessive rainfall will become a
concern as the influx of moisture bumps PWAT levels to 150-200% of
normal. Area burn scars, as well as high flowing rivers, will need
to be monitored. As for temps, plan on below normal readings for
this time of year, with highs in the 60s for the high valleys, and
across the plains 70s on Fri dropping into the 60s to lower 70s for
Sat and Sun.

Monday and Tuesday...Long range models are now trying to bring
another upper closed low onshore across southern CA on Mon, with
temporary ridging developing ahead of it once again over NM, CO and
the Panhandles. Abundant llvl moisture will still be in place so
daily convection is expected, but temps will start to warm back up
both days, nearing seasonal normals by Tue. Moore

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1109 AM MDT Wed May 31 2023

VFR condition are likely for the next 24 hours for all 3 taf sites
KPUB, KALS and KCOS. Winds will be primarily diurnally driven. The
only concern today is passing showers/tsra this afternoon and
early evening. The overall best chance of thunder will be over
KALS, with a lesser chance at KALS and isold activity at best over
KPUB. Any storms in the vcnty of the TAF sites could caused gusty
outflow winds.

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

.DAY ONE...Today and Tonight

Locally heavy rain will be possible today over all of the
mountains and valleys of southern Colorado. Rainfall amounts of up
to a half of an inch will be possible with the strongest storms.
If heavy rain falls on one of the many burn scars across the
region, then flash flooding may occur. In addition to the heavy
rain, areas of small hail, which could accumulate on roadways,
will be possible. If traveling in the mountains today, be alert
for rocks on the roadways and possible flash flooding.

There will be a chance of isolated marginally severe storms along
with locally heavy rain this afternoon across the plains. The
greatest chance for severe thunderstorm activity will be along the
Colorado and Kansas border, and along the Colorado and New Mexico
border. Hail up to 1 inch in diameter will be possible along with
wind gusts to 60 mph. Local flash flooding will be possible,
especially in areas which saw heavy rain yesterday.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Showers and thunderstorms are expected across the entire area on
Thursday, with the main threats being wind gusts to 50 mph, small
hail and cloud to ground lightning. There is the potential for
severe thunderstorms over the far southeast corner of Colorado,
producing wind gusts up to 60 mph and hail up to one and a half
inches in diameter. As moisture increases across the area, periods
of heavy rain and excessive rainfall will become a concern
starting on Thursday, and lasting over the weekend.

The weather pattern will remain quite unsettled over the weekend,
and locally heavy rain will be likely, In addition, strong storms
will continue to be a threat, but the intensity of the storms may
be less due to the cooler temperatures.

.SPOTTER INFORMATION STATEMENT...

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