...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 515 PM MDT FOR
SOUTHWESTERN FREMONT COUNTY...

At 232 PM MDT, Doppler radar indicated thunderstorms producing heavy 
rain across the warned area. Approximately one half inch of rain 
has fallen. Flash flooding is expected to begin shortly.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Hayden Pass burn scar. The debris flow can 
consist of rock, mud, vegetation and other loose materials.

Some locations that will experience flooding include...
Hayden Pass burn scar...Coaldale.

This includes the following streams and drainages...Little Cottonwood
Creek...Arkansas River...Middle Prong Hayden Creek...Big Cottonwood
Creek...Short Creek...Hamilton Creek and Oak Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Stay away or be swept away. River banks and culverts can become
unstable and unsafe.

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.

Please report flooding to your local law enforcement agency when you
can do so safely.

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 515 PM MDT FOR
SOUTHWESTERN FREMONT COUNTY...

At 303 PM MDT, Doppler radar indicated thunderstorms have ended 
across the warned area. Doppler radar estimated up to three tenths 
of an inch of rain has already fallen on the northern fringes of the 
Hayden Burn scar with up to a half of an inch falling on the Hayden 
Creek downstream of the burn scar. Flash flooding of Hayden Creek 
and Fox Canyon Creek downstream of the burn scar is expected to 
continue until the water has a chance to recede.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Hayden Creek drainage. The debris flow can 
consist of rock, mud, vegetation and other loose materials.

Some locations that will experience flooding include...
Coaldale.

This includes the following streams and drainages...Hayden 
Creek...Pole Gulch...and Fox Canyon Creek.

Area Forecast Discussion
National Weather Service Pueblo CO
1127 AM MDT Wed Jun 7 2017

.SHORT TERM...(Today and tonight)
Issued at 543 AM MDT Wed Jun 7 2017

...Line of Storms Expected to Roll off the Mountains onto the I-25
Corridor this Afternoon...

Setup today is pretty similar to yesterday although not so favorable
for convection as you move east of the I-25 corridor.  Multiple high
res model runs, both operational and experimental, have convection
developing over the mountains after 11 am and then growing/expanding
eastward to the I-25 corridor by 2-3 pm and then crossing the
corridor as a line 3-5 pm.  Models then split the line into two main
areas of convection that continue eastward along the Palmer and
Raton Ridges, while weakening eastward propagating convection over
the lower lower Arkansas River Valley.  This means the eastern
mountains and I-25 corridor should see another good shot at showers
and storms today as well as the Palmer and Raton Ridge areas.
However, the plains of the lower Arkansas River valley that did well
yesterday will probably see less activity.  A check of soundings out
that way suggests a persistent capping inversion may be the culprit,
remaining just a bit too warm at the top of the mixed layer.  CAPES
today are similar to yesterday, generally 1,000-1,500 j/kg across
the plains and 500-1,000 j/kg over the mountains.  Surface dewpoints
will remain favorable for convection, generally in the 50s across
the plains and 40s in the mountains.  Shear again looks marginal,
with 0-6 km bulk values only about 25-30 knots.  So, storm risks
today will be similar to yesterday including the potential for some
hail up to about 1 inch in diameter, wind gusts to 60 mph, locally
heavy rain and lightning.  Burn scars will once again need to be
monitored for flash flood potential.  The Fremont County Emergency
Manage noted minor flooding on the Hayden Pass scar yesterday
impacting one outbuilding and a foot bridge.  This can also result
in dark, murky runoff and debris flowing into the Arkansas River,
posing a safety hazard for recreational interests.

On an additional note, peak snowmelt flows for the Arkansas and Rio
Grande will likely occur this weekend or next.  River flows will be
fast and cold for the next few weeks.  The hazard level is
considerably higher now than it will be later in the season when the
snowmelt has ended and warmer, base flows have returned.  Every year
in Colorado, the high flows this time of year result in tragedy,
including some fatalities.  Already, there have been at least 2
deaths reported on Colorado waterways this runoff season.  It is
important to remind everyone how dangerous the high flows can be
this time of year.

.LONG TERM...(Thursday through Tuesday)
Issued at 543 AM MDT Wed Jun 7 2017

Not many adjustments required from previous reasoning with
primary meteorological concerns over the forecast district being
temperatures, gusty winds and pops at times.

Decreasing precipitation trends in combination with above seasonal
early to mid June temperatures are anticipated during the balance
of the longer term as varying degrees of upper ridging/southwesterly
upper flow interacts with varying degrees of eastern Colorado
lee-side surface troughing.

Initially, one more day of isolated to scattered showers and
thunderstorms(although not as widespread as previous couple of
days) are anticipated over the forecast district from Thursday
into Thursday night with some of the stronger storms capable of
producing locally heavy rainfall including the potential of
strong to marginally severe storms at times.

By Friday, isolated showers and thunderstorms are expected to be
focused over eastern portions of the forecast district with
basically dry conditions then anticipated over southern Colorado
from Friday night into possibly Tuesday as primary precipitation
focus at this time remains north to east of the CWFA during this
time-frame.

Above seasonal maximum and minimum temperatures are anticipated
over the forecast district from Thursday into Monday night with
near to slightly below seasonal temperatures expected Tuesday. At
this time, it appears that Friday into the weekend will
experience the warmest temperatures of the longer term with
maximum temperatures challenging the century mark over selected
eastern locations Friday, Saturday and Sunday afternoon. Finally,
the highest potential for gusty gradient winds at times should be
noted from Friday night into Tuesday.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1110 AM MDT Wed Jun 7 2017

A ridge of high pressure is located to the west of the region
bringing NW upper level flow. The surface flow will be from the
SE bringing forcing low level moisture up the terrain. An
embedded shortwave trough will result in thunderstorm initiation
over the mountains, which will propagate over the plains in the
later afternoon hours. Thunderstorms are included in the TAFs for
COS and PUB during the early afternoon, and VCTS for ALS. If the
thunderstorms develop, highly variable winds will be observed,
gusting 35 kts, potentially higher. The flow will switch to a
diurnal flow for ALS, COS, and PUB overnight. Currently, VFR
conditions are expected, but if a particularly strong thunderstorm
develops over COS or PUB, flight conditions will be lower.

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

.DAY ONE...Today and Tonight

Scattered thunderstorms will develop over the mountains after 11
am, then spread eastward into the I-25 corridor around 2 pm.
Thunderstorms will form a broken line as they continue to move
eastward into the southeast plains through the evening then
gradually dissipate as they reach the Kansas border by midnight.
Primary storm risks today will include hail up to the size of
quarters, isolated wind gusts up to 60 mph, locally heavy rainfall
and lightning. Flash flooding will be possible on burn scars, and
over areas which have saturated soil conditions should strong
thunderstorms impact these regions.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Isolated to scattered thunderstorms, some strong to marginally
severe, will again be possible Thursday. The primary
meteorological threats will once again be hail around the size of
quarters, wind gusts around 60 mph, lightning and locally heavy
rainfall capable of producing localized flash flooding, especially
over recent burn scars and over locations that have had recent
heavy rainfall.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening across most of southern
Colorado.
