.SHORT TERM...(This evening through Monday)
Issued at 240 PM MDT Sun Jun 20 2021

Currently...satellite imagery shows widespread cumulus development
across southern Colorado.  A surface boundary is currently backing
westward across the Plains, having reached the I-25 corridor as of 2
PM this afternoon.  Surface flow behind this boundary is east-
northeast, with gusts near 25 mph across much of the Plains.  This
is helping to bring moisture back west, with KPUB in the mid 40s,
and areas east the east seeing lower 50s dewpoints.  Temperatures
are also quite warm, with mostly mid 90s across the region.

Rest of today...the main concern will be the thunderstorm potential
for strong to severe weather across El Paso, Pueblo, Otero and
Crowley Counties.  CAM solutions are a bit all over the place, and
have discounted the HRRR for this afternoon with a very dry bias.
The consensus has moisture working back behind the boundary, with
dewpoints in the upper 40s, helping to produce MLCAPE values around
1000 j/kg.  0-6 km shear values are modest at 30 kts.  An embedded
upper wave in the northwesterly flow is currently moving into the
Pikes Peak region and the boundary itself all point to a continued
severe threat through the afternoon.  If a severe storm does
develop, hail to 1.5 inches and wind gusts to 60 mph may be
possible.  In addition, shear along the surface boundary could lead
to an isolated landspout this afternoon, especially from Pueblo to
Kim.  Storms that form should push southeast this afternoon,
dissipating this evening.

Tonight...a re-enforcing cold front is forecast to drop south into
the Plains overnight, ushering in moist upslope flow across the
Plains.  This will likely lead to widespread showers and
thunderstorms, banked along the Eastern Mountains and I-25 corridor.
Much cooler air will filter in behind the frontal boundary as well.
Overnight lows will be cooler, with 50s across the area.  The main
time frame for precipitation will be after 2 AM for much of the
Plains, prevailing into the morning hours.

Monday...showers and embedded thunderstorms will be continuing for
the morning hours, shifting south along the Eastern Mountains into
the Raton Mesa region.  This shower activity should dissipate with
clearing conditions expected by the early afternoon.  The main thing
people will notice for Monday will be temperatures.  Areas across
the Plains will be significantly cooler, with highs int he 60s to
lower 70s.  The warm spot is expected to be the San Luis Valley with
upper 70s to lower 80s.  Enjoy the cooler weather, because a return
to hot conditions expected by Tuesday. Mozley

.LONG TERM...(Monday night through Sunday)
Issued at 240 PM MDT Sun Jun 20 2021

Monday night-Wednesday...

The cooldown from the passing front and the cloud cover from the
moist upslope flow expected Monday will slowly dissipate into Monday
evening, with clearing skies and low temperatures expected
to only get down into the 50s over the plains. Starting on Tuesday,
models still show an upper ridge building into the area, resulting
in warm and drier conditions for the middle of the week. A few
isolated showers and thunderstorms will be possible on Tuesday and
Wednesday afternoon, but with the weak forcing any showers
would stay over the mountains. High temperatures will increase again
to above-average under the ridge, with the eastern plains expected
to reach back into the low 100s, with high 80s possible over the
higher terrain.

Thursday-Sunday...

The upper-ridge will flatten over the area somewhat as a broad
trough begins building in from the west, delivering some additional
moisture and synoptic-scale lift to the region. More widespread
showers and thunderstorms will be possible, likely originating over
the mountains before the westerly flow aloft pushes it off and east
towards the plains. As the trough axis swings through Friday-
Saturday, a cold front will push south across the area, bringing a
decent temperature cooldown over the plains as well as a higher
chance of precipitation through the weekend.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 240 PM MDT Sun Jun 20 2021

KALS...VFR conditions through the next 24 hours.  A few
thunderstorms may be possible across the San Luis Valley this
afternoon with gusty outflow winds possible at the terminal.  There
could be a few low stratus clouds late tonight into Monday morning
at around 2 kft.  These should quickly clear once the sun comes up,
with VFR conditions into the afternoon.

KCOS and KPUB...a few thunderstorms are expected this afternoon with
gusty outflow winds and briefly reduced CIGS and VIS as they pass
the terminals.  Increasing northeasterly flow will lead to
widespread stratus and rain potential overnight into Monday morning.
Generally MVFR conditions are expected to prevail, which may reduce
to IFR late tonight into the morning.  Expect clearing and a return
VFR conditions by Monday afternoon across both terminals.  Mozley
