.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 122 PM MDT Thu Jun 13 2024

Across the Tri State region this afternoon, skies are sunny for most
except for clouds developing along a front near the I-70 corridor
from Highway 27 and points west. Temperatures as of 100 PM MDT are
ranging from the mid 90s into the lower and mid 100s. Winds are
northeasterly gusting to 20-25 mph at times.

The main wx concerns in the short term period will be the threat for
strong to severe storms during the afternoon/evening hours today and
again on Friday.

For the remainder of the afternoon into tonight, the focus for
convective initiation will be along the frontal boundary which
currently sits along/south of I-70. Some cumulus is popping up and
will be monitored through the afternoon. Parameters suggesting even
some landspouts are also possible initially as storms move along the
front. The latest CAMs are showing convection beginning in earnest
around sunset and continuing into the evening hrs. With a very dry
airmass, soundings are showing strong DCape values around 00z Friday
in the 2200-2400 j/kg range and SBCape/MUCape in the 1800-1900j/kg
range.

Looking for main threats as large hail and damaging winds. SPC has
upgraded the CWA to a Slight Risk for severe, with wind/hail
threats. Can't rule out an isolated tornado as well. The NamNest,
HRRR and RAP all show most of the activity moving east this evening,
with the bulk south of I-70 and the front. Some lingering rw/trw is
possible through 12z Friday, but pops will be in the 30-40% range
tapering to 15-20% overnight.

Going into Friday/Friday night, the region again blanketed under a
Slight Risk for storms, for the afternoon and evening hours.
Guidance is showing the upper ridge currently over the southern
Rockies to shift east into the southern Plains. This will allow for
a couple shortwaves to work into the CWA along the northern
periphery of the upper ridge. The one set to interact with a strong
surface trough during the evening hours, will create the best
chances for severe storms. Wind and hail are main threats, along
with an isolated tornado, especially north of I-70. Soundings
suggest large hail of at least 1-2 inches are possible, with some
2+. PW values of 1-2 inches will also result in the threat for
locally heavy rainfall creating flash flooding concerns. Convection
shifts/clears west to east overnight as both the surface/upper
features clear the CWA towards 12z Saturday. Best chances after 06z
will be east of Highway 25, but the bulk of highest pops 70-80% will
be during the evening hours.

For temps, the region will see daytime highs on Friday range in the
mid to upper 80s. This will be offset by lows tonight ranging in the
lower to mid 60s, and lows Friday night ranging from the lower 60s
west into the mid and upper 60s east of Highway 25.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 1221 PM MDT Thu Jun 13 2024

Saturday we will see the leftovers over the upper-level low move
through and out of the area. This could sparks up some showers and
lower end storms. The greatest potential hazard would be if this
precipitation moved over areas that had been rained on the previous
couple of day, creating a flooding risk.

Sunday, the low will clear the area and we will be under weak
southwesterly flow aloft. This will give us about a 15-20% daily
chance of precipitation due to shortwaves in the evenings, but
nothing highly organized is expected until the weak flow is
disrupted, likely Tuesday afternoon. Around this time, the pressure
gradient tightens up as the low over the NW CONUS pushes farther
inland. This would work to amplify any disturbances and increase
chances for PoPs. By mid-next week, we could see the low moving into
the Great Plains and sending a cold front through the region. This
would spark up some storms and start cooling temperatures down some.

High temperatures until mid-next week look to be in the low 90s to
low 100s. After the cold front moves through, after Tuesday, we will
likely only warm into the 80s and low 90s. Overnight temperatures
will follow a similar pattern and drop into the 60s to low 70s each
night, save for Sunday night. Sunday night, additional cloud cover
and fairly strong winds from the south are expected to keep
temperatures in the mid 60s to mid 70s. Gusts overnight could get up
to 30 kts. Behind the cold front, lows will cool down into the mid
50s to low 60s.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1000 AM MDT Thu Jun 13 2024

For KGLD, looking for mainly VFR conditions through much of the
forecast period. MVFR ceilings probable from 13z Friday onward.
Also, scattered thunderstorms are also possible this evening.
With confidence on timing/placement of any storms low, will
leave off mentioning and update later in the forecast. Winds,
north 10-15kts through 20z, then east-northeast 10-20kts. From
13z Friday onward, east-southeast around 10kts.

For KMCK, VFR conditions expected through the forecast period.
Winds, northerly 15-25kts through 20z before shifting
northeast. From 00z-14z Friday, northeast around 10kts then
shifting to the southeast thereafter.

...Brief Landspout Tornadoes Possible...

At 115 PM MDT, conditions are becoming favorable for the development
of landspout tornadoes in and close to the Seibert. However, at this
time it is unknown which if any storm would produce a landspout. Any
tornadoes which develop are expected to pose a limited threat.

Locations impacted include...
Stratton, Flagler, Seibert, Bethune, and Vona.

To report severe weather, contact your nearest law enforcement
agency. They will send your report to the National Weather Service
office in Goodland.

Landspout tornadoes can form with a developing thunderstorm before
rain, hail, and even thunder is observed. Landspout tornadoes are not
usually associated with a wall cloud and are often difficult to
detect with weather radar.
