The Flash Flood Watch continues for

* Portions of central Colorado and southeast Colorado, including 
  the following areas, in central Colorado, Eastern Sawatch 
  Range, Fremont County, and Upper Arkansas River Valley. In 
  southeast Colorado, Huerfano County, Northern Sangre de Cristo 
  Mountains, Southern Sangre de Cristo Mountains, and Wet 
  Mountains. 

* From Monday afternoon through Monday evening

* Heavy rain from slow moving thunderstorms will be possible.  
 
* Flash flooding will be possible over the burn scars and areas
  that have seen saturated soils due to previous heavy rains. The
  ground in burn scar areas is unstable, so debris flows and
  mudslides could occur in and around the burn scar.  

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a VERY DANGEROUS SITUATION.

You should monitor later forecasts and be prepared to take action
if Flash Flood Warnings are issued.

.SHORT TERM...(Today and tonight)
Issued at 430 AM MDT Sat Jul 25 2020

Main forecast concerns/challenges continue to be with shower and
thunderstorm chances today through this evening across much of the
area, especially along and west of I-25.

No real big change in the overall pattern this morning with south
southwest flow remaining in place, and with a steady stream of
moisture continuing to lift north across the region. At the surface,
surface trough situated across eastern CO, with high dew point air
in the 50s to low 60s in place. With these conditions in place,
another relatively mild morning is expected, with temps then
expected to rise to the 80s and 90s across the plains. Below normal
temps expected over the mountain valleys, as thick cloud cover and
periodic showers and storms will help limit daytime warming.

Scattered showery development is occurring across the higher terrain
this morning and expect this to continue, but do think energy and
moisture helping to drive current showers and storms to the south
will help bring an increase in coverage later this morning. By late
morning/midday, will see daily increase in coverage and intensity of
this precip, with thunder becoming more likely. Isolated to
scattered showers and storms then possible across plains later this
afternoon, especially along the I-25 corridor. Pattern similar to
what was in place Friday is expected this afternoon, and think
slightly higher focus will again be possible closer to the Palmer
Divide. In this location, a slightly stronger storm will be
possible. Tall and skinny CAPE is once again likely though, helping
to limit the intensity of any storm today. Main hazards today will
be lightning and occasional gusty winds, but do think there will be
another risk for localized flash flooding. This will primarily be
across the burn scars though, with all area burn scars at risk as
early as midday. While the risk of flash flooding is expected today,
have not issued a Flash Flood Watch at this time. Confidence is not
that high yet, and also think Sunday and Monday could pose higher
risks not only for the burn scars but for other portions of southern
CO.

By this evening, surface trough/boundary drop south across the area
and think there could be some gusty northerly winds behind it,
especially across the eastern plains. Thunderstorm chances will be
on the decrease in the evening, however, do think showers will
linger slightly longer into tonight. This trough/boundary will mark
the beginning of additional increases in moisture, with high dew
point air and high PWATs appearing likely late this weekend into
early next week across much of southern CO.

.LONG TERM...(Sunday through Friday)
Issued at 430 AM MDT Sat Jul 25 2020

Sunday and Monday...Both days look to be the most active of the
extended period, as the plume of monsoon moisture persists over
New Mexico and Colorado. This moisture tap will fuel convection by
midmorning over the higher terrain, with gradual storm movement
to the northeast across the high valleys and I-25 corridor. At the
same time, a cold front will be pushing into the eastern plains.
Models suggest that the front will drop south of the Palmer Divide
by noon, but then stall somewhat in the vicinity of Highway 50.
This front will eventually push all the way south in the evening,
but as this boundary wavers through the aftn it will serve as the
focal area for storm development. So while storms will initially
fire over the mts, convection is expected to linger well into the
night across the eastern plains. Moving forward to Monday, after
the front has pushed south into New Mexico, easterly surface winds
will allow 60F dewpoints to push west up to the I-25 corridor,
and another round of widespread showers and thunderstorms is
forecast. Healthy QPF amounts both days suggest the potential for
moderate to heavy rainfall rates at times, and if slow-moving
storms develop and track across area burn scars, flash flooding is
a significant concern. Look for max temps in the 70s both days
for the high valleys. Across the plains, temps will climb into the
80s to near 90F on Sunday, then the 70s to around 80F for Monday.

Tuesday...The upper ridge quickly moves west across the state while
a disturbance crosses the Great Basin. There will be plenty of
residual llvl moisture to once again fuel thunderstorm activity
during the aftn and eve. However, surface winds are forecast to be
more southerly so storms will likely be more tied to the higher
terrain, temps will be slightly warmer, and convection should die
off fairly quickly after sunset. Maximum temps will warm into the
70s for the high valleys, and 80s for the plains.

Wednesday through Friday...The ridge restrengthens west of Colorado,
with the ridge axis expected to be in the vicinity of Nevada and
Utah. This positioning will produce drier and warmer conditions for
the forecast area through the end of the work week. Expect isolated
to scattered convection across the region each aftn and eve, with
the best chances tied to the higher terrain. High temps will climb
into the upper 70s to mid 80s for the high valleys, and mid 80s to
mid 90s for the plains. Moore

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1134 AM MDT Sat Jul 25 2020

At KALS, scattered showers and thunderstorms are expected near the
terminal through around 12z. The best chance for a shower or storm
to occur at the terminal is between about 21z and 02z, with gusty
south to southwest winds during that time as well. Outside of the
potential for lowered VIS with showers at the terminal, VFR
conditions are anticipated for the next 24 hours.

At KCOS, showers and thunderstorms are expected to develop over the
nearby mountains early this afternoon and progress eastward. Nearby
showers and storms are anticipated into tonight, with the best
chance for a shower or storm to occur at the terminal being between
about 21z and 01z. Winds are expected to shift to the north this
evening and continuing through the rest of the period. Outside of
the potential for lowered VIS with showers at the terminal, VFR
conditions are anticipated for the next 24 hours.

At KPUB, nearby scattered showers and thunderstorms are expected to
develop this afternoon and last into tonight. Although chances are
limited, an isolated shower or thunderstorm at the terminal cannot
be completely ruled out this afternoon and evening. Gusty southwest
winds are anticipated this afternoon before shifting to northerly
winds. Winds gradually diminish overnight and become light and
variable. VFR conditions are anticipated for the next 24 hours.

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

.DAY ONE...This Afternoon and Tonight

Scattered showers and thunderstorms are expected over the mountains
and mountain valleys this afternoon and evening. Locally heavy rain
will be possible, and any heavy rain that falls over a recent burn
scar will have the potential to cause flash flooding.

A stronger storm or two is possible near the Palmer Divide late this
afternoon through early evening, with the main hazards expected to
be gusty winds and heavy downpours. A few storms will also be
possible across the far eastern plains this afternoon and evening.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

There will be daily chances of afternoon and evening thunderstorms
across all of south central and southeast Colorado.

Thunderstorms will initially develop by midmorning Sunday over
the higher terrain, then activity will spread east across the
plains as a cold front pushes south. Storm activity is expected to
linger well into the night, then reignite on Monday across the
mountains as well as the eastern plains.

The best coverage of storms will be over and near the higher
terrain through the afternoon hours Tuesday through Friday, with a
few of the storms spreading east across the far southeast plains
through the late afternoon and evening.

Slow-moving thunderstorms will be capable of producing locally
heavy rainfall Sunday through Tuesday, increasing the potential
for flash flooding, especially across area burn scars. Other storm
risks will be frequent cloud to ground lightning, with small hail
and gusty outflow winds to around 45 mph possible with the
strongest storms.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening over the mountains and near the
Palmer Divide.
