...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 430 PM MDT FOR
SOUTHEASTERN CHAFFEE...WESTERN FREMONT AND NORTHEASTERN SAGUACHE
COUNTIES...

At 203 PM MDT, Doppler radar indicated thunderstorms producing heavy 
rain moving across the warned area. Around one half inch of rain has 
already fallen in the San Luis, Dorsey, and Lone Tree Creek 
drainages. Flash flooding is ongoing or expected to begin shortly.

HAZARD...Life threatening flash flooding. Heavy rain producing flash 
         flooding.

SOURCE...Radar indicated.

IMPACT...Life threatening flash flooding of creeks and streams, 
         urban areas, highways, streets and underpasses.

Excessive rainfall over the burn scar will result in debris flow 
moving through the San Luis, Dorsey, and Lone Tree Creek drainages. 
The debris flow can consist of rock, mud, vegetation and other loose 
materials.

Some locations that will experience flooding include...
Decker Burn Scar.

This includes the following streams and drainages...
Rock Creek, Alder Creek, South Arkansas River, Arkansas River, Lone
Tree Creek, Dorsey Creek, Bear Creek and San Luis Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.
Residents living along streams and creeks should take immediate
precautions to protect life and property.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 430 PM MDT FOR
SOUTHEASTERN CHAFFEE...WESTERN FREMONT AND NORTHEASTERN SAGUACHE
COUNTIES...

At 311 PM MDT, Doppler radar indicated light rain falling across the 
warned area as heavier thunderstorms have already moved through. 
Around one half inch of rain fell in earlier storms. Flash flooding 
may be ongoing with the earlier rains.

HAZARD...Life threatening flash flooding. Heavy rain producing flash 
         flooding.

SOURCE...Radar indicated.

IMPACT...Life threatening flash flooding of creeks and streams, 
         urban areas, highways, streets and underpasses.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Lone Tree, San Luis, and Dorsey Creek drainages. 
The debris flow can consist of rock, mud, vegetation and other loose

This includes the following streams and drainages...
Rock Creek, Alder Creek, South Arkansas River, Arkansas River, Lone
Tree Creek, Dorsey Creek, Bear Creek and San Luis Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Remain alert for flooding even in locations not receiving rain.
Arroyos, streams, and rivers can become raging killer currents in a
matter of minutes, even from distant rainfall.

Move away from recently burned areas. Life-threatening flooding of
creeks, roads and normally dry arroyos is likely. The heavy rains
will likely trigger rockslides, mudslides and debris flows in steep
terrain, especially in and around these areas.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.

Area Forecast Discussion
National Weather Service Pueblo CO
1133 AM MDT Sun Jul 19 2020

.SHORT TERM...(Today and tonight)
Issued at 418 AM MDT Sun Jul 19 2020

Currently...

Quite a bit of mid and upper level cloudiness was noted over the
lower elevations at 3 AM this morning. A couple of light showers
were scattered across the plains, with a few IC flashes as shown by
the GLM. This shower and cloudiness activity was associated with a
front that has pushed across the region earlier this evening. This
front has pushed moisture back into the region with 50 dewpts noted
across most of the plains. 40s were noted in the San Luis valley
with 30s in the rest of the valleys.

Today...

Cooler weather with more showers and storms are likely to occur over
the area today as more instability is over the region with the
increased low level moisture. Favorable upslope flow combined with
modest mid level NW flow aloft will set up a favorable shear
pattern, so a few marginally severe storms are possible over the
area this afternoon and evening. SPC has the area outlooked in a
marginal category and this looks about right given the forecasted
environmental shear and cape values that will be over the region
later today. The primary severe weather threat today will be hail up
to quarters and wind gusts to 60 mph.

With increased moisture over the interior, a flash flood watch was
issued yesterday for the burn scars across the Wet mtn and Sangre de
Cristo region. Confidence is not overly high regarding this watch,
but given the available moisture over the region, the potential for
heavy rain over the burn scars will be with us today.

Max temps will be in the 80s to lower 90s across the plains this
afternoon, with 80s in the valleys.

Tonight...

Showers and storms, some potentially marginally severe,  will move
across the plains  this evening, with most if not all of the
activity exiting the state into KS by midnight. No low cigs are
expected over the region late tonight. Mins tonight will fall into
the U50s and 60s plains with 40s in the valleys. \/Hodanish

.LONG TERM...(Monday through Saturday)
Issued at 418 AM MDT Sun Jul 19 2020

Monday-Tuesday...Weak west to northwest flow aloft continues across
the region through the early portion of the week, as a large area of
upper level high pressure stretching from the southern High Plains
through the southern and central Rockies and into the southern Great
Basin and Desert Southwest, remains intact. Models continue to
indicate drier air in place across the Intermountain West filtering
into the Rockies on Monday, with more weak energy and embedded moisture
moving through the ridge into the Rockies on Tuesday. With that said,
there looks to be enough residual moisture to work with strong summer
sunshine to support isolated to scattered showers and storms Monday
afternoon and evening. Monday's convection, however looks to be
more high based, with more inverted V soundings indicated across
the high valleys and into the I-25 Corridor, with the best coverage
of storms over the higher terrain. Further east, convection looks
to be capped on Monday, however can't rule out a few storms
through the late afternoon and early evening hours. On Tuesday,
there looks to be better coverage of storms, especially across
over and near the higher terrain, with any convection the far
eastern plains likely capped through the late afternoon once
again. With the weak flow aloft, locally heavy rainfall could lead
to localized flash flooding, mainly if storms develop or move
across the area burn scars. Temperatures to be around seasonal
levels through this period, with highs in the mid 80s to mid 90s
across the plains, and in the 60s to lower 80s across the higher
terrain.

Wednesday-Saturday...Latest model runs continue to indicate flow
aloft becoming more south to southwest through the middle of the
week and into early next weekend, as a broad upper trough developing
across the West Coast shunts the upper high south and east of the
Rockies. This will open the door to more subtropical moisture to
filter into western and central Colorado through the rest of the
extended period. This will lead to increasing coverage of daily
showers and storms through the period, with the best chances of
wetting rains over and near the higher terrain. Further east,
convection looks to be capped through most of the day, with the
potential more isolated storms through the late afternoon and early
evening hours. With generally weak steering flow aloft, locally
heavy rainfall and the potential for flash flooding will remain the
main risks with storms through next week. Temperatures through the
period to remain around seasonal averages.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1132 AM MDT Sun Jul 19 2020

Showers and thunderstorms will be in the vicinity of KALS, KCOS,
and KPUB this afternoon. If a storm develops over any of the
terminals, erratic and gusty winds are possible, as well as MVFR
and IFR conditions. Storms are expected to move out of the
vicinity of the terminals by around 1800-1900 MDT, then VFR
conditions are expected throughout the rest 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

Scattered showers and thunderstorms will develop over the entire
region this afternoon and last into this evening. Some of the storms
over the plains will have the potential to become marginally severe
producing winds to 60 mph and hail up to the size of quarters. Over
the mountains, slow moving storms will have the potential to produce
locally heavy rain, which will have the potential to cause flash
flooding over the numerous burn scars.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

There will be daily chances of afternoon and evening thunderstorms
across south central and southeast Colorado Monday through Saturday.
The best coverage of storms will be over and near the higher terrain
in the afternoons, with some storms spreading south and east across
the far southeast plains through the late afternoon and evening hours.
With generally weak steering flow aloft, storms will be slow moving
and capable of producing locally heavy rainfall. This will also lead
to the potential for flash flooding, especially for area burn scars.
Other storm risks will be frequent cloud to ground lightning, with
small hail and gusty outflow winds to around 45 mph.

.SPOTTER INFORMATION STATEMENT...

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