Area Forecast Discussion
National Weather Service Pueblo CO
353 PM MDT Fri May 26 2017

.SHORT TERM...(This evening through Saturday)
Issued at 354 PM MDT Fri May 26 2017

...Active severe weather pattern next couple days...

Moisture has been slow to recede across the southeast plains this
afternoon with dew points as of 20z in the mid-upper 40s.  Weak
disturbance evident in WV imagery is currently moving through
southwest CO and should provide at least some weak lift across the
area this afternoon through this evening.  Meanwhile...models
sharpen up the dry line along a line from KCOS to just east of KPUB
to Kim, CO by 21z.  Various high res models show 2 areas of isolated
thunderstorm initiation this afternoon...one along the dry line
across eastern Las Animas county...and another across Teller and El
Paso counties. Strength of storms today will be dependent on how
much moisture mixes out and various models differ with this. Dew
points which stay up in the mid to upper 40s will yield CAPE values
in the 1000-1500 j/kg range.  If they drop back into the 30s...then
CAPES sliver out aloft pretty quick.  0-6 KM shears in the 40-50 kt
range according to NAM favors potential for supercells with main
threat being large hail and damaging winds.  Although tornado threat
does not look terribly high...there could be a brief tornado if
rapid storm updrafts can stretch vorticity along boundaries.  For
now this looks like an outlier potential...but bears watching.

Activity shifts eastward into Kansas by 7PM with activity decreasing
across southeast CO. Another front drops through the plains
overnight with the potential for stratus to develop across portions
of the plains by Saturday morning.  This primes up the area for
another round of more widespread thunderstorms Thursday afternoon as
the western U.S upper trof finally moves across.  Looks like
convection should fire around 18z across the mountains.  Amount of
instability will be the main concern for thunderstorm strength on
Saturday but atmosphere will be strongly forced so suspect strong to
severe storms will be possible once again with best area for severe
being south of highway 50 and along the Raton Ridge. Deep layer
shears will be running around 50-60 kts...and although large hail
and damaging winds will be the primary threat...an isolated tornado
would be possible along the Raton Ridge where low level easterlies
maximize.  There is some concern that atmosphere will be capped at
least initially...farther to the east.  High res models suggest
convection evolves into an MCS which propagates eastward through the
evening.  Heavy rainfall on burn scars will be a concern as well.
-KT

.LONG TERM...(Saturday night through Friday)
Issued at 354 PM MDT Fri May 26 2017

Not many significant adjustments required from previous
meteorological thinking as unsettled conditions are still
anticipated during the longer term with main issues continuing to
be temperatures, pops/qpf, winds, and the potential for strong to
severe thunderstorms as well as locally heavy rainfall at times.

Longer range PV analysis, computer simulations and forecast model
soundings continue to suggest that upper disturbances interacting
with north-northeasterly surface surges/surface boundaries over
southern Colorado into later next week.

It still appears that the highest potential for more widespread
locally heavy rainfall and stronger to possibly severe
thunderstorms at times over the forecast district during the
longer term should be experienced Saturday evening, Monday and
then again by late week.

Finally, below seasonal late May maximum temperatures are
projected from Saturday into Tuesday, with maximum temperatures
then expected to run near to slightly above late May/early June
climatological averages from Wednesday into next Friday. Also,
near to above seasonal minimum temperatures are anticipated during
the longer term.

&&

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
Issued at 354 PM MDT Fri May 26 2017

Thunderstorms will be possible this afternoon...particularly at the
KCOS TAF site...with VCTS possible at KPUB after 22z.  Hail and
damaging winds will be possible with thunderstorms...particularly
east of a line from KCOS to just east of KPUB to near Kim, CO.
Thunderstorms should clear out of eastern CO by 02z.  A cold front
will bring another northerly wind shift through eastern CO overnight
with MVFR stratus developing towards 12z for both KCOS and KPUB as
winds shift around from the east. This will set the stage for a
better chance for showers and thunderstorms on Saturday with locally
heavy rain and vis restrictions into the MVFR/IFR category with the
stronger storms.

KALS will see VFR conditions over the next 24 hours.  Gusty
southwest winds will decrease by 02z.  Lighter winds are expected by
Saturday though there will be a better chance for an isolated
thunderstorm in the vicinity of the terminal after 20z Saturday.

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

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorms will be possible this afternoon
and evening over the central mountains, portions of Fremont county,
Teller county, and portions of the southeast plains.  There will be
the risk of severe thunderstorms, mainly east of a line from
Colorado Springs to just east of Pueblo to Kim. The main severe
storm threats will be hail up to the size of golf balls and wind
gusts around 60 mph, however an isolated tornado cannot be ruled
out. Deadly cloud to ground lightning will be a risk with all
storms.

Showers and thunderstorms over the higher peaks of the central
mountains and Pikes Peak, could result in some light snow
accumulations.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

An active weather pattern will continue across southern Colorado.
Saturday looks like the most active day in the period with
scattered showers and thunderstorms expected over most of south
central and southeast Colorado. A few strong to severe storms will
be possible on Saturday, particularly along the Raton Ridge.
Locally heavy rainfall on burn scars will also be a concern on
Saturday, particularly for the newer burn scars such as Junkins
and Hayden Pass.

Otherwise isolated to scattered thunderstorms will be possible
each day, mainly in the afternoon and evening hours. The primary
storm threats will be lightning and wind gusts up to 45 mph with
a few of the stronger storms producing some small hail.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will be
possible this afternoon and evening over the central mountains,
Pikes Peak, Teller county, and over portions of the southeast
plains.
