Area Forecast Discussion...CORRECTED
National Weather Service Pueblo CO
619 PM MDT Tue Aug 20 2024

.KEY MESSAGES...

- Another round of thunderstorms today, some strong to
  marginally severe across portions of the southeast plains.
  Localized flash flooding possible.

- Daily afternoon and early evening showers and storms are
  expected Wednesday night through Saturday.

&&

.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 214 PM MDT Tue Aug 20 2024

Drier air is evident in WV pics across northern portions of the area
behind yesterday's departing shortwave to the north.  Monsoon plume
still holding strong across southern sections with weak
perturbations riding through the flow.  Dew points remain high
across the plains today with readings in the 50s to lower 60s while
dew points have dried out into the 40s across El Paso to around 50
along the Raton Ridge.

For the rest of this afternoon and tonight...active monsoon plume
will generate thunderstorms and push them off into the adjacent
lower elevations through the late afternoon and evening, with
greatest coverage across southern areas where precipitable waters
will remain high (120-140%). Dew points are progged to remain in the
40s along portions of the I-25 corridor, especially the Pikes Peak
region today as lee troughing aides in mixing out some of the low
level moisture. However southeasterly flow along the Arkansas River
and Raton Ridge should keep an axis of higher dew points and CAPE in
place across the southeast plains.  HREF mean CAPE values of around
1000-2000 J/kg will be in place east of the I-25 corridor, with 500-
1000 J/kg along the I-25 corridor and points westward.  High res
models shift winds southeasterly towards 00z and tries to advect
higher dew points back northward into the Palmer Divide triggering
another round of thunderstorms across El Paso county this evening.
All in all, it looks like another active day for thunderstorms
(though less than yesterday out east) with best coverage across the
mountains, valleys and southern I-25 corridor. Plains will start out
capped, but with some southerly flow increasing this evening overtop
the frontal boundary across southern sections of the area, can't
rule out a convective cluster working its way southeastward from the
Palmer Divide into the eastern plains overnight. NAMNest and HRRR
runs continue to advertise this scenario. Available instability
won't be as strong in the overnight hours and the axis of the
stronger southerly low level flow appears to stay to the south and
east, so confidence in storm coverage during the late evening hours
east of the I-25 corridor is low.  With deep layer shears 25-30 kts,
a strong to severe storm or two still looks possible through the
evening, with greatest likelihood south of the Arkansas River
valley.

Thunderstorm coverage ramps up for Wednesday as a disturbance
embedded within the monsoon plume moves across southern CO in
southwest flow aloft.  Precipitable waters increase out west (up to
150% of normal).  Increasing flow aloft nets around 30-35 kts of
shear, with strongest values across northern and western sections of
the area.  Can't rule out a strong to marginally severe storm or
two, though risks will likely transition more towards a heavy
rain/flash flood threat for burn scars and urban areas. Another
round of thunderstorms will push off the mountains into the adjacent
plains in the afternoon, though dew points look slightly lower and
storms are likely to be higher based which may keep things in the
sub severe category.  Some smaller hail, gusty outflow winds and
heavy rainfall will be possible. -KT

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
Issued at 214 PM MDT Tue Aug 20 2024

Wednesday Night - Saturday: For much of the long term period, a
relatively consistent pattern will be in place as monsoon flow
persist. A ridge of high pressure will be in place, and moisture
will be streaming into the ridge and over the region. While no major
forcing is expected, diurnal upsloping and modest orographic
forcing, in combination with the moisture in place, will allow for
daily afternoon rain showers and thunderstorms to blossom. The
greatest coverage of showers and storms will be along the mountains,
where any forcing will be greatest, and especially Wednesday, when a
minor wave gets ingested into the western periphery of the high
pressure. Gusty winds, heavy rain, and lightning are the anticipated
hazards with any more organized thunderstorms. With that all said
though, as instability wanes during the evening hours, any
precipitation present will lessen in coverage. Looking at
temperatures, the warmth continues over south central and
southeastern Colorado. With the ridge sitting over the region, above
seasonal temperatures are expected.

Sunday - Monday: For the end of the weekend and start of next week,
a pattern change is anticipated. A lifting trough will pass
near/over south central and southeastern Colorado Sunday. This wave
will flatten the ridge and scour out some of the moisture as drier
air pushes in behind the wave. Then Monday, as the wave exits, messy
flow will remain in place as the ridge tries to rebuild. With that
all said, drier conditions are expected given the drier air advected
over the region, even despite the heightened forcing from the wave.
The exception to this will be isolated showers and weak storms along
the mountains given some forcing and modest moisture still in place.
Any precipitation present during the afternoon hours will dissipate
during the evening hours as instability lessens. As for temperatures
the warmth is expected to cotinue Sunday as downsloping winds
prevail. Then Monday, a cool down is likely as cold front sags
southward behind the exiting wave.

&&

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 550 PM MDT Tue Aug 20 2024

Scattered showers and storms over the higher terrain are expected
to move east across the high mountain valleys, the I-25 Corridor
and possibly across the far southeast Plains through the rest of
the evening. These storms could bring gusty outflow winds and
produce brief MVFR conditions in brief heavy rainfall at the
terminals, with COS having the best chances of seeing storms.
VFR conditions with partial clearing skies through the overnight
hours, with another round of storms expected again Wednesday
afternoon.

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

.DAY ONE...Today and Tonight

Thunderstorms will develop over the mountains around noon and
spread eastward into the adjacent plains and valleys late this
afternoon and evening. Although thunderstorm coverage will be less
than yesterday, one or two strong to severe thunderstorms will be
possible across the southeast mountains, adjacent plains, and the San
Luis Valley. The main risk with thunderstorms will be hail up to
the size of quarters, wind gusts up to 60 mph, lightning, and
heavy rainfall capable of producing localized flash flooding.
However, larger hail up to the size of half dollars and wind gusts
up to 70 mph will be possible across southern portions of the
southeast plains where greater low level moisture will remain in
place.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Scattered to numerous afternoon and evening thunderstorms will continue
across the area Wednesday through Friday, with the greatest chance
for storms over the mountains and lower chances over the far southeast
plains near the Kansas border. The main hazards from storms each day
will be heavy rainfall and potential flash flooding, along with lightning,
small hail and gusty winds.

Storms will decrease in coverage and intensity over the weekend into
early next week, with most activity remaining over and near the
mountains through the period.

.SPOTTER INFORMATION STATEMENT...

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