Area Forecast Discussion
National Weather Service Pueblo CO
301 PM MDT Tue Aug 4 2020

.SHORT TERM...(This evening through Wednesday)
Issued at 237 PM MDT Tue Aug 4 2020

Currently...

Thunderstorms were beginning to develop along the I=25 corridor,
especially in El Paso and S Las Animas county, with more isolated
activity in the mtns. SPC has just recently issued a severe
thunderstorm watch for most of the plains until 9 pm this evening.
CAPES are already in the 1-2K range and shear was increasing. A sfc
low was in the vicinity of KPUB and favorable sfc flow was noted to
the NE of this low.

Through this evening...

Best low level and deep shear is located to the northeast and east
of the sfc low. This will allow the strongest convection to develop
across east central Colorado, especially in areas from KLHX to KLAA
and then down south to vicinity of KSPD. Some big hail will be
possible and would not be too surprised if we see golf balls and
Tennis balls later today. TOR threat appears to be very low as short
range guidance is not showing any persistent helicity tracks and no
well defined boundaries were noted over the far eastern plains.
gusty winds to 70 mph will also be possible.

There is a possibility that we may see some outflow push back
towards the mtns, and this may lead to additional convection later
this evening. Cant rule out these storms could be marginally severe.

Later tonight...

Cant rule out some straggling storms during the early morning hours,
but believe most of the convection should be out of the state by
late evening.

Tomorrow...

A bit cooler weather will be over the region and expect convection
will initiate later in the afternoon tomorrow. It is questionable of
how much low clouds will be over the region tonight. Expect low
clouds will linger near the border, but hi res guidance is showing
the plains along the I-25 corridor should be mostly cloud-free.

Storms will once again likely be severe as plenty of low level
moisture should be over the region and winds aloft will be a bit
stronger, so deep shear will be larger and storms may be a bit more
organized. SPC has the region is marginal risk for now but would not
be too surprised if this is increased to slight in later updates.

Unlike today where the mtns are rather dry, some moisture is likely
to work back to the mtn valleys and expect the threat of burn scar
flooding will return to the region.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 237 PM MDT Tue Aug 4 2020

Models continue to be in good agreement through the extended
period. That gives a bit higher confidence in the forecast.
Ensemble spreads are modest beyond Sunday.

Wednesday night...strong to severe storms will be ongoing across
the Plains during the evening hours. The strongest storms will
likely be lined up from the Palmer Divide, south and east to near
La Junta and Lamar. Large hail and strong winds along with locally
heavy rain will be possible, mainly before midnight. Expect
thunderstorm activity to continue south and east across the
Plains, clearing by Thursday morning.

Thursday...upper level ridging will move across Colorado with
southwesterly flow spreading across the state by the afternoon.
Embedded energy will lead to scattered thunderstorms across the
region. Drier air working in from the west will likely limit
coverage, with gusty outflow winds the primary threat.
Thunderstorm activity will spread east across the Plains overnight
clearing into Kansas by Friday morning.

Friday through Tuesday...high pressure will be centered over Texas
with upper level ridging stretching into the Northern Plains.
Meanwhile upper troughing will sit along the west coast. This will
keep southwesterly flow across Colorado for the next several days.
Drier air will move into the area and will keep thunderstorm
coverage limited through this period. Most thunderstorms will
remain confined to the higher terrain, with gusty outflow winds,
lightning and small hail possible each day. Very weak flow aloft
should keep thunderstorms anchored to the terrain, with very
little if any thunderstorm activity on the Plains. If embedded
energy from the south can move across Colorado, thunderstorm
coverage will be greater, however, at this time, individual
disturbances are hard to pinpoint.

Temperatures through the extended period will be on a warming
trend. Better mixing of drier air from the Desert Southwest will
allow temperatures to warm through the 90s to near 100.  Mozley

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 237 PM MDT Tue Aug 4 2020

KCOS and KPUB

 Some thunder will be possible at this afternoon and we may see some
thunder late this evening as boundaries work back to the west from
strong convection over the eastern plains. The main concern is low
clouds redeveloping tonight at these two taf sites. Guidance at this
time is not to high bringing low clouds back, but this potential for
low clouds will have to be watched carefully. Thunderstorms will
once again be possible tomorrow afternoon, but the storms will
likely form later in the day.

KALS...

VFR next 24 hours with only a slight chance of a passing high based
TSRA producing locally gusty winds.

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

.DAY ONE...This Afternoon and Tonight

Severe thunderstorms are possible over the plains this afternoon
and evening.

Storms are expected to form over the I-25 corridor around 1 to 2 PM
with the strongest storms over this area capable of producing 60
mph winds and quarter sized hail.

Later this afternoon the storms will continue to move east and
are expected to intensify further. The strongest storms will be
capable of producing tennis ball sized hail and 70 mph winds. The
storms should affect the La Junta area around 5 to 7 pm, and the
Lamar and Springfield regions after 6 pm. the strongest activity
should move out of the state of Colorado after 10 pm.

Overall, the greatest threat of severe weather today will
generally be east of a line from Black Forest to La Junta to
Springfield.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Scattered thunderstorms are expected over the eastern mountains
and plains Wednesday afternoon and evening, with isolated storms
possible in the high valleys and along the Continental Divide.
There could be a couple or a few severe storms over the southeast
plains and I-25 corridor, with wind gusts around 60 mph and hail
the size of ping pong balls being the main risks.

Isolated to scattered thunderstorms are expected Thursday across
southern Colorado. On Friday, mainly isolated storms will be
possible over the mountains and high valleys, and portions of the
I-25 corridor.

Saturday through Monday it looks a little drier but there will
still be the possibility of isolated storms over the mountains,
high valleys and I-25 corridor.

All storms will be capable of producing potentially deadly
lightning and gusty winds. Some of the stronger storms will also
be capable of producing locally heavy rain and small hail. If
heavy rain moves over a recent burn scar, there could be a flash
flood and debris flow risk.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible over the plains this afternoon and evening.
