327 PM MDT Fri Jul 1 2022

.SHORT TERM...(This evening through Saturday)
Issued at 227 PM MDT Fri Jul 1 2022

Key Messages:

1) Thunderstorms shift from the mountains to the plains this
evening, heavy rain/flash flooding and severe wx all possible.

2) Another round of thunderstorms expected Saturday, though heavy
rainfall threat may stay mainly over the higher terrain.

Thunderstorms were widespread over the mountains at mid-afternoon,
with some activity already into the I-25 corridor as of 21z. Have
seen a few, severe hail producing supercells over the higher
terrain so far, though weak 0-6km shear (25-35 kts) has kept most
stronger storms rather short-lived. Have also seen some pockets of
heavy rainfall, with localized flooding/rockslides along Highway
285 over Poncha Pass. Convection today is being forced by well
defined short wave lifting northeastward through the 4 corners,
while mid-level moist plume and low level upslope flow provide
plentiful moisture and instability. For this evening, activity
shifts eastward onto the plains, with most CAMs suggesting
activity makes it to the KS border by midnight. Again, a brief
severe storm east of I-25 is possible, and pockets of heavy rain
and flash flooding will accompany the stronger storms as well.
Activity diminishes after midnight, though some showers/sprinkles
will likely linger into Saturday morning on the plains.

On Saturday, low and mid level moisture remain in place, though
upper forcing may be weaker with lack of a well defined short wave
over the area. Expect fairly widespread convection over the
mountains once again, with heavy rainfall threat continuing. Storm
coverage from I-25 eastward a little more questionable, though
steering currents have enough wly component while weak low level
upslope flow persists, suggesting at least scattered convection
makes it onto the plains, especially late in the afternoon. Max
temps Saturday likely to drift upward a few degf, especially
plains where clouds/storms will likely arrive fairly late.

.LONG TERM...(Saturday night through Friday)
Issued at 227 PM MDT Fri Jul 1 2022

Key messages:

1) On Sunday, scattered PM thunderstorms will develop over the
mountains with some of them moving over the plains during the
evening. Some storms could become strong over the mountains with
flash flooding.

2) Scattered PM thunderstorms over the mountains and isolated storms
over the plains will be possible on Monday, mainly I-25 corridor.
Better chance of PM storms over plains on Tuesday through Thursday.
PM storms will be more confined to the mountains next Friday.

Detailed discussion:

Saturday night through Sunday...

Scattered to numerous thunderstorms which have formed over the
mountains during the afternoon on Saturday will be moving out over
the plains during the evening, especially over the southern areas of
the CWA. CAMs are displaying more widely scattered areas of
convection south of the US-50 continuing to move of towards the ENE
and over the eastern plains later in the evening, and also over the
Palmer Divide. There looks to also be an area of higher CAPE for
both areas (of anywhere between 1000 to 1600 J/kg for the eastern
plains and 800-1000 J/kg for the Palmer Divide) which will help to
sustain any convection moving over these areas of the CWA. Bulk
shear is not great, but there will be some higher values between 30
to 35 kts over the northern areas of the CWA Higher areas of CAPE
over the mountains may also keep thunderstorm initiation going into
the late evening hours and possibly after midnight and into early
Sunday morning. Clearing skies will take place after about this
time, with temperatures falling into the upper 50s to mid 60s over
the plains and generally in the 40s to low 50s for high country, and
upper 30s for the fourteeners.

On Sunday, as the ridge will continue to undergo more amplification
and the monsoonal moisture plume remains nearly in place with a
slight shift back towards the northwest, thunderstorms will again
impact most of the mountainous areas of the CWA with orographic
lifting as the forcing mechanism. With the southwesterly mid level
flow in place, some of the storms will make it off the mountains and
move out into the plains. There will be juicier air over the eastern
plains, so some of the longer-lived storms that make it all the way
into this more unstable environment will have the potential of
becoming severe. Given the sounding profiles with higher LCLs, and
likelihood of higher level updraft development, higher confidence is
that stronger outflows will produce gusty winds possibly in excess
of 60 mph if storms do become severe. There will also be the
possibility of hail of 1 inch or greater if cores become more
elevated above -20C. The higher values of DCAPE will remain more
confined over the southeastern plains, although this area will also
be lacking mid-level moisture, although if a cell does form near the
CO/OK border in Baca County, it will have a greater potential of
producing severe outflow winds. Moreover, relatively higher CAPE
values over the Sangre de Cristo Mountains of around 1500 J/kg and
Rampart Range of nearly 2000 J/kg a little later in the evening will
provide a good chance of developing thunderstorms that could also be
on the stronger side, or perhaps even severe. The southern Sangre de
Cristo Mountains will be another area worth watching due to the
higher CAPE and weak shear over the area. This could allow for
storms to become nearly stationary, which could produce brief
periods of torrential rainfall with possible flash flooding,
especially over burn scars, with the Spring scar in particular that
will be the most at risk.

Monday...

On Monday, the monsoonal moisture plume is going to begin to shift a
little more to the west and north as the ridge further strengthens.
This will allow for afternoon and evening thunderstorm activity to
be more confined to the mountainous areas of the CWA. There could be
some thunderstorms moving off the mountains and over the adjacent
plains by later in the afternoon, although given the mid-level flow
being more from the SSW, this should not allow for thunderstorms to
move much further east than the I-25 corridor. Most of the
convection with the highest precipitable water looks to remain over
the Continental Divide. Although, given the favorable most unstable
CAPE of around 1400 J/kg and steep mid level lapse rates around
8C/km, stronger storms with high rainfall rates over the Sangre de
Cristo Mountains may occur and keep the risk of flash flooding in
place for the burn scars. Instability does appear to be weaker over
the eastern plains, therefore if any storms do make it east of the I-
25 corridor, it is more likely that they will fall apart and
dissipate.

Tuesday through Friday...

Ensembles and deterministic models alike are in close agreement that
the long wave trough over the northwestern CONUS will remain nearly
stationary and keep the ridge over central CONUS throughout this
period in the forecast. As the ridge overhead begins to flatten
slightly, along with weak perturbations moving through in the
longwave troughing upstream, the monsoonal moisture plume will shift
back to being more over southeast Colorado, which will provide more
widely scattered to numerous PM thunderstorms to develop over most
areas of the CWA for Tuesday through Thursday. There will be a weak
cool front moving through late afternoon on Tuesday, with winds
shifting to a northeasterly-easterly direction over the plains,
which will allow for a slight cooldown on Wednesday through
Thursday. By Friday, as the ridge begins to build back again over
the region and the upper level high over Texas begins to slightly
retrograde back to the west, the moisture plume will also shift back
to the west with a more north to south orientation of the ridge axis
and keep any thunderstorm initiation confined to the mountains with
a more northward mid-level flow. There will continue to be possible
flash flooding concerns over the burn scars due to weaker mid level
shear throughout the week. Temperatures on Friday will also be much
warmer under the strengthening ridge with 600 dm heights over
western Colorado showing up on the ECMWF at the 500mb level.  -Stewey

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

.DAY ONE...This Afternoon and Tonight

Scattered to numerous thunderstorms will develop over the
mountains early this afternoon, then spread into the adjacent
plains from mid-afternoon into this evening. The main risk with
thunderstorms today will be locally heavy rainfall, lightning,
small hail and wind gusts up to 45 mph. There will be an elevated
risk for flash flooding on burn scars today should they be
impacted by a stronger storm.

As storms move into the southeast plains, a few strong to severe
thunderstorms will be possible between 2 PM and 10 PM.  Hail around
1 inch in diameter, and wind gusts around 60 mph will be possible
with these stronger storms, especially across Crowley, Kiowa, Otero,
Bent, Prowers, Eastern Las Animas and Baca counties. While the
stronger storms will push eastward into Kansas after 10 PM, isolated
to scattered showers and thunderstorms may persist into the
overnight hours, especially over the mountains and near the Kansas
border.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Scattered to numerous rain showers and thunderstorms are likely
Saturday through Monday, with the best coverage over the higher
terrain. The primary storm risks will be locally heavy rainfall,
which could produce flash flooding, especially on area burn scars.
Lightning and small hail will also be possible with the stronger
storms.

Afternoon and evening thunderstorms will gradually become more
isolated to widely scattered Tuesday through Thursday, with the
highest coverage remaining over the higher terrain.

.SPOTTER INFORMATION STATEMENT...

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