336 PM MDT Thu Jul 6 2023

.SHORT TERM...(This evening through Friday)
Issued at 335 PM MDT Thu Jul 6 2023

...Scattered to numerous severe storms will be likely over portions
of the plains this evening through early morning tomorrow and there
could be more severe storms again tomorrow over the plains...

Key messages:

1) Scattered to numerous severe storms will be likely over the
plains through the early this evening through early tomorrow
morning. Very large destructive hail of 3 inches or greater in
diameter, as well as damaging outflow winds up to 90 mph, and even a
few tornadoes will be possible.

2) Scattered thunderstorms will occur over the higher terrain
tomorrow afternoon and then make their way over the plains by late
afternoon and through the evening hours. Some of these storms will
likely become severe and may also contain large hail, damaging
winds, and a slight risk of a tornado or two.

3) There could be some patchy fog and drizzle possible over parts of
El Paso and Pueblo counties during the morning hours tomorrow.

Detailed discussion:

Currently and through tonight...

Satellite imagery shows that most of the lower stratus deck has
continued to mix out and diminish over a good portion of the plains.
There  The latest SPC mesoanalysis shows...

The same persistent east-southeasterly flow in the lower levels has
continued to bring in more saturated air throughout the evening with
dewpoints getting into the low 60s all the way back up against the
mountains. As how it was yesterday, depending on how much of the
stratus mixes out will determine just how unstable it will become
over the eastern plains by later this evening. That being said, it
is worth noting that high resolution models, even the HRRR with
having a dry-mixing bias, have been struggling handle the amount of
CIN in place and have underestimated the development and intensity
of projected reflectivity as a result. Similar to yesterday has been
the erosion of the stratus deck being over the southern I-25
corridor initially earlier this morning. If this is any indication
of persistent forecasting, then this area may again be the first to
have a severe thunderstorm develop this afternoon as the lower
levels continue to destabilize more rapidly with more efficient
surface heating. Although, what may prevent this from occurring is
drier air moving in from the west in the mid levels, which may
suppress storm initiation over the southern Sangres.

CAMs have been generally consistent with most of the convection
developing around the Palmer Divide area early this evening and then
having a few discrete cells merging into an MCS later in the evening
and moving southeastward over the eastern plains to the Kansas
border by around 2 to 3 AM. Given the high amount of MUCAPE topping
over 3000 J/kg in some areas, as well as very strong effective bulk
shear between 60 and 70 kts over most of the plains, it is likely
that storms not affected by surface capping will become severe with
the potential of producing very large and destructive hail of 2 to 3
inches or possibly greater, and damaging straight-line outflow winds
up to 90 mph. Also, given increasing low-level helicity mainly east
of the I-25 corridor, a few tornadoes cannot be ruled out,
especially over far eastern El Paso County and south-southeast to
eastern Las Animas County, and eastward to the CO/KS border.

Low level moisture is going to remain in place over the plains with
a stratus deck reforming and overcast skies will be expected again
tonight. There could also be some areas of patchy fog or drizzle
possible again, especially over northern El Paso County with
upsloping over this area. It will be generally mostly clear over the
higher terrain. Lows will be around the upper 50s to the low 60s
fore the plains, and 40s to low 50s for high country.

Tomorrow...

The low level stratus deck is going to stick around until the
earlier morning hours tomorrow and not remain in place as long. This
will keep the environment near the surface relatively saturated,
with dewpoints likely remaining in the 50s through the course of the
day for most of the plains. This will further enhance the
destabilization and allow for high CAPE values in excess of 3000
J/kg to be shifted a little further south and eastward as there will
be better mixing further west. This better mixing will also allow
for the convective temperature to be achieved and capping possibly
broken earlier and further westward than previous days. Because the
conditionally unstable environment is already in place, along with
effective bulk shear still quite strong and greater than 50 kts in
most areas with steep lapse rates by mid afternoon, this could once
again set the stage for there to be some severe storms.

Most of the latest CAM guidance has El Paso and Pueblo counties, and
near the Raton Mesa as having initial convection by early afternoon
tomorrow. Given earlier convective more probable, coverage of storms
could be greater tomorrow, especially further west along the I-25
corridor. With all of the aforementioned parameters in
consideration, if storms do become severe, they will likely produce
very large hail again of 2 inches in diameter and perhaps strong
outflow winds of 70 mph or greater. A tornado or two will also be
possible, although I do suspect not as high of a chance as today due
to lower SRH values, and more confined to the far southeastern
plains where there is better low level helicity. High temperatures
will be even warmer tomorrow over the plains and closer to the
seasonal average, which will likely also aid in better updraft
intensification and sustainability of thunderstorms. -Stewey

.LONG TERM...(Friday night through Thursday)
Issued at 335 PM MDT Thu Jul 6 2023

Key Messages:

1) Storm chances across eastern Colorado persisting into the early
   Weekend.

2) Warmer and drier for the late weekend into early next week.

Friday night-Saturday night...Models continue to indicate minor
waves embedded within moderate west to northwest flow aloft across
the Intermountain West through the Northern High Plains through
the end of the work, as upper level high pressure builds across
the Southern High Plains through the Southern Rockies and into
the Desert Southwest. This will keep generally dry, warm and breezy
conditions across western portions of the area through this period,
with meteorological critical fire conditions likely through the afternoon
and evenings. The latest fuel status from land management agencies
remains non critical, however, will need to continue to monitor as
said warm and breezy conditions prevail. Further east, we will continue
to see chances of showers and storms, with severe weather possible, as
low level moisture ebbs and flows across the southeast Plains. SPC has
the southeast plains in a marginal to slight risk of severe storms
Friday and again on Saturday. Temperatures across western portions of
the area expected to be at to slightly above seasonal levels, with
near to below seasonal temperatures expected across eastern Colorado.

Sunday-Wednesday...The upper high remains progged to build across
the Great Basin and into central Rockies later in the weekend into
early next week, leading to a warming and drying trend areawide.
The ridge over the Rockies flattens again into the middle of next week,
leading to a slow increase in available moisture and increasing chances
of showers and storms, mainly across eastern Colorado.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 335 PM MDT Thu Jul 6 2023

VFR conditions at KCOS and KPUB will return to MVFR and possibly IFR
criteria at KPUB, and return to IFR and possible LIFR criteria at
KCOS due to lowering CIGs/BR, mainly after 06Z. They should improve
again at both stations after 14Z or shortly thereafter. SHRA and
TSRA could be possible in and around the vicinity of KCOS and KPUB
through this evening and then tomorrow, with greater confidence of
this occurring at both stations after 18Z tomorrow. If TSRA does
develop, it could temporarily reduce CIGs and VIS to MVFR/IFR
criteria and result in periodic windshifts and increased wind
speeds. VFR conditions VFR are expected at KALS throughout the
forecast period and winds at this terminal should be more diurnally
influenced with gusty SW'ly winds during the afternoon and early
evening hours. Winds will be mainly synoptically driven with morning
for KCOS and KPUB with east-southeasterly flow near the surface, and
then become more diurnally towards the end of the forecast period.

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

.DAY ONE...This Afternoon and Tonight

Patchy fog is expected to be in the vicinity of Colorado Springs
and across northern El Paso county through early afternoon.

Severe thunderstorms are expected late this afternoon into the
evening hours. Development will initially be over and near the
southeast mountains, but then will move into the I-25 corridor by
mid to late afternoon and then the remaining plains through the
evening hours. The strongest storms will be capable of producing
hail in excess of two inches, wind gusts to 80 mph, and tornadoes.

While severe storms will be possible anywhere across the plains
today, highest chances will be along and north of the Highway 50
corridor. The risk of storms is expected to lower just after
midnight tonight.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

Strong to severe thunderstorms are possible Friday and Saturday
over the Interstate 25 corridor and the eastern plains. The
greatest chances for severe storms will be along and east of a
line from Colorado Springs to Kim. The main threats from these
storms will be large hail, damaging winds, and isolated tornadoes.

Elevated fire weather conditions are expected over the
Continental Divide Region, San Luis Valley and Upper Arkansas
River Valley. Gusty southwest winds and low daytime humidities are
expected through at least Sunday. Next week, low daytime
humidities are expected, but winds will become lighter.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

.SPOTTER INFORMATION STATEMENT...

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