.SHORT TERM...(This evening through Friday)
Issued at 349 PM MDT Thu Jun 28 2018

Currently...Steady southwest feed aloft, with high pressure pushing
in from the southeast, has kept the forecast area hot and dry.
Limited moisture has helped fuel isolated convection over the
southern mts this aftn, which in turn has produced strong gusty
outflow winds. Meanwhile, Spring Creek Fire in the vicinity of La
Veta was producing a good amount of smoke over the Sangres and Wets,
and in the Walsenburg area. Cloud development over the eastern mts
this aftn has helped to curb the heating slightly, but temps have
still climbed into the mid 80s to lower 90s for the high valleys,
and 90s to low 100s for the plains.

Tonight and Friday...Very little change expected over the next 24
hours. Poor humidity recovery overnight as temps drop into the 40s
and 50s for the high valleys, and 60s for the plains. Southwest flow
aloft will continue through tomorrow, while models indicate that
aftn convection will occur further east over the plains with the far
east under a Marginal outlook for severe thunderstorms. Meanwhile,
the higher terrain and southern foothills will once again be under
the gun for critical fire weather conditions, and a Red Flag Warning
is in place from noon until 9 pm tomorrow for those areas. Temps are
forecast to climb into the 80s for the high valleys, and mid 90s to
low 100s for the plains. Moore

.LONG TERM...(Friday night through next Thursday)
Issued at 349 PM MDT Thu Jun 28 2018

Primary longer term meteorological issues include temperatures,
pops/strong to severe thunderstorm potential at times as well as
elevated near critical to critical fire weather conditions at
times.

Initial longer term meteorological issues include the Red Flag
Warning continuing over primarily western and southern sections
into Friday evening as well as the potential for strong to severe
thunderstorms over primarily far eastern locations into Friday
Friday night and then again possibly on Saturday(which aligns with
SPC's recent Day 2 and Day 3 Severe Thunderstorm outlooks), thanks
to somewhat favorable forecast capes/LI's/deep layer shear and
atmospheric moisture values.

In addition, a healthy northerly surface surge is projected to
push across eastern sections from late Friday night into Saturday,
allowing for some welcome relief in the form of cooler
temperatures over eastern locations this weekend with projected
maximum temperatures climbing into the 80s both Saturday and
Sunday as compared to the 100 degree readings realized the
previous few days.

Also, recent computer simulations, longer term PV/Precipitable
water analysis and forecast model soundings suggest that upper
ridging centered over Oklahoma at 12Z Monday shifts into Indiana
by 06Z Wednesday before reforming over Colorado by later next
week.

For sensible weather during this time-frame, increased pops are
anticipated by mid-week next week as deeper atmospheric moisture
circulates into the forecast district in combination with
generally low-grade gradient winds.

Finally, as touched upon earlier, eastern locations should
experience near to below seasonal late June to early July
maximum temperatures this weekend, with generally above seasonal
temperatures then expected from Monday into next Thursday.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 349 PM MDT Thu Jun 28 2018

VFR conditions expected across much of the forecast area over the
next 24 hrs, including the three main TAF sites of KCOS, KPUB and
KALS. Brisk southwest sfc winds gusting to 25 mph, as well as gusty
outflow winds from isolated convection, is expected to diminish this
evening by 03z. Spring Creek Wildfire in vcnty of La Veta produced a
good amount of smoke that may reduce vsby over the Sangres, the Wets
and vcnty of K4V1 through the evening hours. Similar pattern in
place for tomorrow. Moore

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

.DAY ONE...This Afternoon and Tonight

Winds are expected to increase through the afternoon and evening
hours. The increased winds, combined with continued hot and dry
conditions, will lead to critical fire weather conditions this
afternoon through the early evening, especially over and near the
higher terrain and across northern portions of the southeast
plains.

Isolated, high based afternoon thunderstorms, will again be
possible this afternoon across the Southeast Mountains and Plains,
with the main storm threats being lightning, and gusty outflow
winds.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

High fire danger can be expected Friday afternoon and evening over
the mountains and high valley locations, where the fuels are dry
and the winds will be gusty, and the humidities low. Isolated to
scattered thunderstorms are expected over the far southeast plains
Friday afternoon and evening, and there will be the potential for
one or two storms to become severe, with large hail and damaging
wind gusts being the main severe threats. Lightning will be a
threat with all storms, along with gusty outflow winds.

Isolated to scattered thunderstorms will be possible Saturday and
Sunday over the eastern mountains and plains, and possibly also over
the mountains along the Continental Divide on Sunday.
Thunderstorms will be possible, mainly over and near the
mountains Monday through Wednesday. All storms will produce
lightning, and will also have the potential to produce gusty
outflow winds.

.SPOTTER INFORMATION STATEMENT...

Weather spotters will not be needed this afternoon or tonight.
