Hail in Colorado, May 30, 2025

Area Forecast Discussion
National Weather Service Pueblo CO
528 PM MDT Fri May 30 2025

.KEY MESSAGES...

- Scattered thunderstorms this evening over the mountains/I-25
  corridor and portions of the plains.

- Warm this weekend, with scattered afternoon
  showers/thunderstorms both days (best storm chances Sunday
  afternoon over the mountains).

- Cooler and wetter weather pattern redevelops next week, with
  daily chances for showers/thunderstorms and temperatures much
  below seasonal averages Tuesday and Wednesday.

.SHORT TERM /THROUGH SATURDAY/...
Issued at 224 PM MDT Fri May 30 2025

Convection finally starting to fire over the higher terrain as of
2pm, as air mass over the mountains has become moderately unstable
(CAPE 500-1000 J/KG). CAMs suggest storms spread southeast into the
I-25 corridor in the 5-10 pm window, and HRRR is particularly
aggressive with convection around Pueblo and Colorado Springs
this evening. Will bump up pops slightly along I-25 to follow
this trend, and nudged some pops eastward onto the plains to
around La Junta to account for weakening storms toward sunset.
Lightning/small hail/gusty winds to 50-55 mph the main storm
threats, a gust over 60 mph is not out of the question along
I-25 this evening, where downdraft CAPE is 500-700 J/KG. Storms
end by midnight, with clouds clearing toward Sat morning. Sat
looks like a repeat of Friday, with warm afternoon temps and
another round of high terrain storms moving across the I-25
corridor late in the day. Current forecast looks on track and
made only minor adjustments.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 224 PM MDT Fri May 30 2025

Initial old srn stream cut-off low finally get swept up in the
flow late Sun/Mon, while nrn stream cold front drops south
through the plains Mon night. Pattern should lead to increased
convection over the mountains Sunday afternoon/evening as
moisture is swept northward ahead of the approaching low, with
weak lee trough on the plains potentially focusing storms east
of the mountains Sun afternoon and evening. Max temps will again
be warm, with 80s and 90s widespread at lower elevations.
Showers may linger through much of Sunday night over the higher
terrain toward the Continental Divide, as increasing mid-level
moisture flows northward into the area. Upper low then lifts
out across Colorado on Monday, with fairly widespread convection
over the mountains and valleys as a result. I-25/plains precip
chances on Mon slightly more questionable, as surface low spins
up over nern CO and low/mid level winds turn fairly strong
westerly through the day. While we'll still see at least
scattered convection across the lower elevations given
instability and upward motion, suspect downslope will mean a
good portion of the any showers/storms will be
windy/sprinkles/virga.

Cold front moves quickly southward through Colorado Monday
night, and while best forcing for precip will stay over the
northern half of the state initially, southern edge of the
heavier precip will eventually sag southward across the Palmer
Divide and impact areas along and north of the Arkansas River by
early Tuesday morning. Much cooler with showers/thunderstorms
Tuesday afternoon/evening, as post-frontal upslope deepens while
next short wave trough drops into AZ. Slightly warmer Wed with
another round of showers/thunderstorms as wave moves through,
then slow warming trend Thu/Fri, though showers will linger as
moisture remains in place and numerous weak upper waves eject
out of the broad western U.S. trough.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 528 PM MDT Fri May 30 2025

KALS: VFR conditions are expected through 24 hours. Though some
showers and storms may linger over the nearby mountains for a few
hours this evening, confidence regarding any direct impact to the
terminal is low. Even so, will monitor for any outflow that travels
downslope, though currently no strong gusts are anticipated. Weak
winds below 10 knots and some mid-level clouds will last through the
end of this forecast period.

KCOS: Thunderstorms will persist in the area for several hours this
evening. Put VCTS in the prevailing 00Z group, with a PROB30 for -
TSRA through 03Z. At the moment, storms appear to remain to the
southwest of the terminal, but will monitor for any additional
formation and/or outflow winds. Gusts in the area will persist
around 20 knots or so, with thunderstorm gusts potentially
increasing that threshold closer to 30 knots. Once precipitation
leaves the area later this evening, northwest winds around 10 knots
with decreasing clouds overnight. More diurnal winds pick up on
Saturday, with another chance for more showers and storms in the
afternoon.

KPUB: Passing showers and storms are expected to glance by the
terminal starting around 02Z. Storms should weaken after dark, with
precipitation ending in the area by 04Z or so. Diurnal winds under
10 knots persist overnight and into Saturday with decreasing clouds.
Chances for showers and storms increase again towards the end of the
period, though current data shows nothing close by before 00Z
Saturday afternoon.
