Area Forecast Discussion
National Weather Service Pueblo CO
1129 AM MDT Fri Jun 30 2023

.UPDATE...
Issued at 1129 AM MDT Fri Jun 30 2023

Firt piece of shortwave is lifting north and east across the
Northern Front Range with secondary trough digging across
south central Colorado and developing convection attm. Latest
CAMs continue to indicate storm intitation across the Pikes
Peak/Palmer Dvd region, as well as along the Raton Mesa by early
afternoon, with storms merging across the far southeast plains
the late afternoon. Still looks like main threats will be large
hail of 1 to 2 inches in diameter and strong damaging winds of
60 to 70 mph, with a low end threat of a tornado, especially
along the Palmer Divide and Raton Mesa, where CAM helicity tracks
have been consistent.

&&

.SHORT TERM...(Today and tonight)
Issued at 343 AM MDT Fri Jun 30 2023

Key Messages:

1) Scattered to numerous thunderstorms WILL occur today, quite a few
strong to severe storms possible (likely?).

2) Storms will likely initiate early (18Z?) and will likely clear
the region by early evening.

3) Uncertainty exist on the overall intensity of storms given that
they will initiate relatively early in the day.

4) Locally heavy rain likely, cant rule out some local flash
flooding issue (but storms should be moving pretty quickly).

Currently...

Per water vapor sat pix imagery, a well defined albeit broad
positively tilted trough of low pressure was located over the
intermountain west, with the axis extending from west central WY to
western AZ. A well defined dry slot, along with modest southwesterly
flow was noted in advance of this system. Regionally, numerous
showers with some embedded thunder was noted across the west central
high plains in advance of this weather system. Locally, a band of
showers was located over the SE CO plains, extending from roughly
Kim to Lamar at 3 AM.

Lots of clouds were noted over the plains, but most of this
cloudiness was mid and upper level clouds per sfc obs. Some low
clouds were noted over the Palmer Divide.

Today...

Quite a bit of uncertainty exist in this forecast. Based on current
data, I am confident that we will see quite a bit of convection over
the region this afternoon. Confidence is also high in that the
storms will likely initiate early, typically during the 18-20 UTC
time frame (this is 3-4 hours earlier than normal), and then move
east and should be out of the region by early evening. The main
concern I have at this time is the overall expected intensity of the
convection as it pushes across the plains this afternoon. Plenty of
shear will be available, so any sustained updraft will rotate. The
concern will be how much CAPE will be available for the storms? In
addition, with all the forcing moving across relatively early, will
see lots of weak convection (vs isolated strong convection?). Plenty
of low level moisture is available (albeit the quality of the
moisture is modest (50 dwpts), but the amount of instability may be
limited due to the early initiation of the storms. It should be
noted that temps aloft are rather cool, and predicted lapse rates
will be in the 8-9 C/KM range, so the potential for robust updrafts
and large amounts of CAPE in the mid levels could be realized.

Based on the above, large hail appears the primary concern today,
with the greatest threat over the far eastern plains (this region
will see the longest amount of heating). Given the lapse rates,
stretching should be strong, so a tornado threat will be with us.
HREF guidance was indicating the best llvl shear will be over the
eastern sections of the Palmer Divide (Kiowa county) while the
strongest overall shear will be down along the Raton Mesa. Not
surprisingly, the best helicity swaths from the CAMS were noted over
the two divides.

Based on what we know at this time, I anticipate a severe weather
watch will be issued, likely a blue box (svr thunderstorm watch) for
this afternoon for our plains. SPC as of 06 UTC, has the area
outlooked in slight risk, with hatched hail (>2.00") and a low end
tor threat. The greatest threat for most significant svr activity
will be over the far eastern plains.

As for the heavy rain threat, storms should be moving relatively
quickly. so the duration of the heavy rain should be relatively
short lived. Also we have been dry last couple of days so we had
some time to dry out. With that said, northern El Paso county is
still quite saturated as I traveled across this region yesterday
and there was lots of observed standing water.

In a nutshell...

1.) if you have the opportunity to park your car in a garage (or a
parking garage at work if you live in the metro areas) it may be a
good idea to do it.

2.) If this system was coming through later in the day, my
confidence would be higher that we would see a more significant
severe weather episode, however it is coming through early in the
day (decreasing CAPE potential) and the forcing will be
rather strong, so we may see lots of weak storms.

Tonight...

Storms will likely clear the region by early evening, with clearing
thereafter. I cant rule out some low clouds/fog over the plains
tomorrow morning. \/Hodanish

.LONG TERM...(Saturday through Thursday)
Issued at 343 AM MDT Fri Jun 30 2023

Key Messages:

1) Chance of strong to severe storms on Sunday.

2) Drier on Monday, storms return Tuesday-Wednesday.

3) Unsettled pattern should continue the rest of the week.

Saturday will be a bit on the quieter side. Drier air will be moving
in and synoptic scale subsidence will be present over most of the
western half of the state. High temperatures will be in the 70s-80s
across most of our forecast area, and cloud cover will be minimal.
Overall, the dry air should work to greatly limit the development of
afternoon showers and thunderstorms. Some isolated showers may form
along a weak trough axis as it ejects out to our east. Greatest
confidence for precipitation will be over and near the higher
terrain.

Temperatures and precipitation chances both increase again on
Sunday. Northwest flow will set in aloft over our area, and a small
wave will be passing through and disturbing the upper-level flow,
giving us an extra boost to potential thunderstorm formation in the
afternoon. High temperatures will surge back into the low-90s over
the plains, and model guidance does hint at low-mid 50s dewpoints
returning to our eastern counties as well. For instability, a
generous amount of CAPE is forecasted over the area, varying
depending on which model you like the most, with 500 J/kg on the
lower end and over 2000 on the high end of the CAMs. Shear is also
variable depending on the model, but 20-30 knots is a reasonable
average expectation. All this to say that afternoon thunderstorm
development on Sunday seems likely, and that some of these storms
could become strong to severe, especially over our southeast plains
and the Palmer Divide. This will be the day to watch.

Looking into next week, the pattern becomes less certain as model
solutions begin to diverge, but some of the broader details are in
good agreement. Monday will be slightly drier once again as flow
aloft turns more zonal with an upper low far to our north. Some
isolated to scattered convection will still be possible over our
higher terrain, but that's about it. Tuesday-Wednesday look a bit
more active as a wave passes by overhead and sends a cold front
south across the plains. While Tuesday looks a bit more on the
convective side with warmer temps and higher dewpoints,
precipitation on Wednesday should be more widespread thanks to post-
frontal winds and moisture. High temperatures will also be knocked
down closer to or just below seasonal norms. Flow turns zonal later
this week and daily chances for showers and storms are expected to
continue.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1040 AM MDT Fri Jun 30 2023

Mainly VFR conditions expected at COS and PUB through the taf
period, with brief MVFR to local IFR conditions possible as
scattered storms move across the I-25 Corridor between 19Z-23Z
and then continue into the far southeast plains through the late
afternoon and early evening. Thunderstorm threats at the terminals
include hail and gusty outflow winds and along with locally heavy
rainfall, with the best chances of storms being at COS.

VFR conditions look to prevail at ALS over the next 24 hours, with
breezy southwest winds through the afternoon.
