.SHORT TERM...(Today and tonight)
Issued at 352 AM MDT Tue Aug 7 2018

...Another round of severe thunderstorms with the potential for
Flash Flooding this afternoon and evening...

Thunderstorms still ongoing across the plains producing heavy
rainfall across southern portions of the southeast plains where
the low level jet continues to override the surface front and
realize sufficient lift to keep thunderstorm regenerating. These
will continue to pull east through early morning with a downward
trend in pops.

Upslope flow will keep plentiful low level moisture in place
across the southeast mountains and plains today.
Meanwhile...area will remain under northwest flow aloft and under
the storm track of a series of upper level disturbances. One will
be exiting eastern CO this morning...though another will be moving
in this evening and overnight. With dew points expected to remain
in the 50s to lower 60s this afternoon across the southeast
mountains and plains, surface heating will help realize 1500-2000+
J/kg of SBCape across the southeast mountains. Deep layer shears
will still be in the 40-50 kt range which will be supportive of
supercell thunderstorms capable of producing large hail, damaging
winds and intense rainfall rates. In fact, pattern looks similar
to yesterday, except the forcing with shortwaves appears to be a
little less juxtaposed with max day time heating. This may serve
to keep activity a little less widespread than yesterday. Given
the high CAPE and moisture content, have opted to put out another
Flash Flood Watch for the southeast mountains and I-25 corridor
for this afternoon through midnight. Primary concern areas will be
burn scars and urban areas...however many areas received heavy
rainfall yesterday and these areas will also be susceptible to
flash flooding should they be impacted again.

Easterly winds have penetrated into the San Luis valley resulting
in an increase in dew points early this morning. Although models
mix out this low level moisture during the afternoon...think there
will be sufficient residual moisture for at least some isolated
thunderstorms farther westward into some of the interior valleys.
Gusty winds will be more of a threat given the inverted V
soundings...but some near severe hail and locally heavy rainfall
will be possible where sufficient moisture remains pooled on the
westward edge of the moist airmass.

Tonight...00z model runs suggested another cluster of nocturnal
convection will develop across the southeast plains with focus
across Las Animas county where low level jet upglides overtop of
surface front across northeast NM. There could be another cluster
which develops across east central CO and drops
southeastward across the far eastern plains overnight. This may be
forced by the shortwave in NW flow which makes its arrival rather
late across the far eastern areas. Will maintain isolated to
scattered pops across most of the plains through the overnight
hours. -KT

.LONG TERM...(Wednesday through Monday)
Issued at 352 AM MDT Tue Aug 7 2018

The relatively wet pattern will continue into Wednesday with
upslope flow keeping 50+ dew points across the plains. Forcing for
Wednesday appears less well defined as the upper ridge nudges
eastward. This will serve to decrease the deep layer shears which
may limit storm organization some for Wednesday afternoon and
evening. Still some moderate CAPE (1000-2000 j/kg) will be
present to support another round of strong to severe thunderstorms
for the southeast mountains and adjacent plains. Heavy rainfall
potential with the risk for flash flooding on susceptible burn
scars will continue. Difficult to say if we will need another
flash flood watch this day. Certainly the risk will be there, but
greatest thunderstorm coverage may shift farther southward into NM
which may keep threat more isolated for southern CO.

Amplifying western U.S. upper high will continue to shift eastward
for Thursday and Friday which will put southern CO under more
northerly and even northeasterly flow aloft. This will keep focus
for thunderstorms farther west across the mountains with southerly
to southwesterly storm motions limiting the ability for
thunderstorms to drift into the adjacent plains. Sufficient
residual moisture will be present for a localized heavy rainfall
threat and storm motions will be slower as a result of weaker flow
aloft. So a localized flash flood threat will continue.

A drying and warming trend sets in for next weekend into early
next week with best focus for thunderstorms along the Continental
Divide. -KT

.AVIATION...(For the 12Z TAFS through 12Z Wednesday morning)
Issued at 352 AM MDT Tue Aug 7 2018

MVFR stratus will persist across the lower eastern slopes of the
southeast mountains and upper Arkansas river valley this morning.
Pockets of MVFR cigs/vis with fog will be possible for areas which
received heavy rainfall last night. Will keep a tempo group for
fog at KCOS and KPUB though this may be a brief occurrence around
sunrise. Skies will clear this morning with another round of
thunderstorms expected to develop across the mountains during the
afternoon. KCOS and KPUB could see TSRA ad the terminals this
afternoon and evening, and if impacted by one of the stronger
storms, even some GR will be possible. Will reflect this in a
tempo group for KCOS, though may keep VCTS in for KPUB as
certainty is a little lower. Erratic gusty winds will be possible
with thunderstorm outflows for both terminals.

KALS could see some brief MVFR cigs this morning as low level
easterly surface winds have brought low level moisture westward
through the passes into the San Luis valley. Any clouds should
quickly burn off by 15z...with VFR conditions expected through the
afternoon. High based thunderstorms will be possible in the San
Luis valley by late afternoon with gusty erratic winds up to 40
kts the primary storm threat. The very isolated coverage should
limit the potential for the KALS terminal so will not put a VCTS
group into the TAFs just yet. -KT

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

.DAY ONE...Today and Tonight

Plentiful moisture will remain in place across the southeast
mountains and plains today which will result in another round of
thunderstorms. These will develop across the mountains during the
afternoon and moving off into the adjacent plains during the late
afternoon and evening hours. A few storms will become severe with
large hail up to 2.5 inches in diameter, and wind gusts up to 70
mph the primary storm risks. The location at greatest risk for
severe thunderstorms today will be across the eastern slopes of
the southeast mountains and the I-25 corridor counties from El
Paso county to the New Mexico border. An isolated tornado will
also be possible, particularly south of highway 50.

Intense rainfall rates will be likely again today which may
result in flash flooding, particularly for the burn scars in the
southeast mountains such as Spring, Hayden Pass, Junkins, and
Waldo. Urban areas and locations with saturated soil conditions
from yesterday's heavy rainfall will also be prone to flash
flooding if impacted again today.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

Scattered thunderstorms will redevelop across the mountains and
adjacent plains on Wednesday. One or two storms could become
strong to severe across the southeast mountains and plains with
large hail and damaging winds possible. Locally heavy rainfall
capable of producing flash flooding will be possible for area burn
scars once again.

Isolated to scattered thunderstorms will be possible across the
mountains for Thursday and Friday with a general drying trend
expected for the weekend into next Monday. The primary storm
threats will be lightning, brief heavy rainfall and wind gusts up
to 40 mph.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be possible this afternoon and evening across the southeast
mountains and adjacent plains.
