.KEY MESSAGES...

- Warmer for the rest of the work week. A low chance of
  thunderstorms Thursday and Friday, a couple strong northeast
  corner late Friday.

- Thunderstorm chances and intensity increase this Memorial Day
  Weekend.

- Somewhat cooler and daily chances of showers/storms lingers into
  Memorial Day, and early next week.

.DISCUSSION /Through Wednesday/...
Issued at 250 PM MDT Wed May 21 2025

Main forecast concern will surround thunderstorm chances and
intensity as we head into the Memorial Day Weekend. Until then,
we`ll be in a warm weather pattern, but still a couple
thunderstorms around (~20% coverage).

Breezy conditions and any lingering showers/weak storm over the
mountains and northeastern plains will come to an end by this
evening with a drying and stabilizing airmass. Temperatures will
be just below normal given clearing skies and a fairly dry airmass
in place.

Thursday will feature a continuation of our recent warming trend,
with highs across the plains pushing into the 75-80 degree range as
the thermal ridge shifts closer to the forecast area. Regarding
shower and storm chances, we expect temperatures to get just warm
enough to spark a few showers/storms over the higher terrain in
the afternoon, shifting onto portions of the plains by very late
afternoon and evening. Any showers and storms will be high based
and light due to a deep and dry subcloud layer. A few of these
could produce gusty outflow winds to 40+ mph given the inverted-v
profiles and DCAPE growing to over 1000 J/kg.

Friday is still shaping up to be the warmest day of the week
ahead, as the upper level ridge and thermal ridge shift across
Colorado. We expect highs to push into the mid to upper 80s on the
plains, with 70s in the foothills and high valleys, and mainly
60s in the mountains. Low level moisture starts to increase on
the plains, and that will lead to increasing MLCAPE with up to
around 1000 J/kg over the northeast corner, while west of that
(roughly Sterling to Akron) it will be much drier. There will also
be a battle between sufficient instability along that
dryline/moisture interface for any stronger surface based
convection. Typically these scenarios can offer a narrow ribbon
where a couple stronger or even isolated severe storms could
occur, so that`s still something to watch on the eastern plains
for Friday late afternoon and evening. SPC has moved the northeast
corner of the state into Marginal Risk for Friday and that seems
reasonable. Finally, it will be breezy again, but spring green-
up is sufficient for fuels to be not receptive to fire spread at
this time.

The weather pattern becomes more active this weekend, as an upper
level trough, increasing low level moisture, and some upslope all
join together. For Saturday, low level moisture is expected to
increase further as east/southeast winds develop and advect higher
dewpoints across the High Plains. This occurs as surface pressure
falls are expected ahead of an upper level trough pushing east
across the Great Basin and Northern Rockies. That would be more
favorable for stronger and potentially a few severe storms. The
trend in the models is for a stronger push of upslope, so this
could more effectively push the threat of severe storms closer to
the Front Range and I-25 Corridor. Meanwhile, the eastern plains
could stay much cooler with light showers/drizzle around -
effectively limiting a stronger storm threat there. For Sunday,
there has been a continued trend toward cooler temperatures, which
would limit instability and any severe storm threat. Sunday is
also trending wetter with the arrival of the upper trough, QG
lift, and deeper moisture. Showers and a couple thunderstorms will
be likely (60-70%) chance across nearly the entire forecast area.

While considerable uncertainty still exists for the eventual
weather pattern early next week (caught somewhere in between a
trough to the east and a building ridge/weak zonal flow over the
Great Basin or Northern Rockies), we`ll likely see a continued
chance of showers and a few storms each day. That will be due to
lingering moisture in light flow aloft. Temperatures should begin
a slow warming trend, which typically leads to increasing
instability and a few stronger storms possible as we head toward
midweek.

.AVIATION /00Z TAFS through 00Z Friday/...
Issued at 519 PM MDT Wed May 21 2025

Winds have refused to go NW due to the presence of a Longmont
anti-cyclone. Radar does show a boundary approaching from the NW
of DIA so there still could be a window of NW winds between 00Z
and 02Z. After 02z winds will become more NE or E. After 06Z
winds may go light SE and then more Southerly by 13z. By early Thu
aftn winds will become more ESE. VFR conditions will remain in
place thru Thu aftn.

.BOU WATCHES/WARNINGS/ADVISORIES...
None.
