Area Forecast Discussion
National Weather Service Cheyenne WY
215 PM MDT Tue Jun 7 2022

.SHORT TERM...(This evening through Thursday)
Issued at 215 PM MDT Tue Jun 7 2022

Forecast concerns are for severe thunderstorms today through early
this evening.

Currently...Surface boundary looks to be shifting east early this
afternoon. Dewpoints at 40 degrees here at Cheyenne...basically
along the Interstate 25 Corridor to Douglas. East of this
front...low to mid 50s dewpoint being observed in the Nebraska
Panhandle. Latest EMC RAP guidance from SPC Mesoanalysis Page
showing SBCAPE 1500-1800J/KG...with 0-6km shear values around
70kts. Already getting some pretty strong storms on our radar in
two locations. Across Converse and Niobrara Counties...several
strong to potentially severe storms are being observed. South
across Scottsbluff County and points south...storms are beginning
to develop and moving east. Upper shortwave seen on IR imagery
near Casper currently...continues to push east and will aid in
thunderstorm development through the afternoon.

For the rest of the afternoon...storms will continue to develop
ahead of that boundary as CAPE and shear values remain quite high.
Discrete storms look to bow out once the storms move out to near
Alliance and Sidney late this afternoon. HRRR forecasts an early
show...with storms ending after 1900 or so tonight.

Wednesday looks dry as upper shortwave that is moving through our
area now tracks into eastern Nebraska. Do have another upper vort
max moving through the upper ridge Wednesday afternoon...but it is
looking to track into northeast Wyoming.

.LONG TERM...(Friday through next Tuesday)

Weather Highlights:

1) Rapid warming Friday and into the weekend. Temperatures could
climb into the 90s Saturday for eastern Wyoming and the Nebraska
Panhandle. Temperatures on Sunday could climb into the upper 90s in
the Nebraska Panhandle with upper 80s across eastern Wyoming.

2) Thunderstorm chances return Sunday, with chances for showers and
thunderstorms lingering into next week.

3) A storm system will push a cold front through the area Monday
night, which will cool temperatures down on Tuesday.

Overview: The long term forecast continues to support a rapid warm-
up occurring across central and eastern Wyoming and the Nebraska
Panhandle. Seasonal temperatures will be quickly replaced by 15-20F
above normal high temperatures, just in time for the weekend. Just
how hot is it going to get? Latest forecast update has continued to
trend warmer as the NBM is now showing a high temperature of 90F for
Cheyenne on Saturday with widespread 90s across eastern Wyoming and
the Nebraska Panhandle. The record high temperature for June 11
(Saturday) for Cheyenne is 92F set back in 2013. Temperatures will
remain well above normal on Sunday, but could trend slightly cooler
as afternoon showers and thunderstorms and a shift in the flow aloft
will contribute to the slightly cooler temperatures, but
temperatures across the southern Nebraska Panhandle could push into
the mid to upper 90s! As mentioned, a return to afternoon showers
and thunderstorms is possible come Sunday afternoon, with another
round of thunderstorms possible again on Monday. Some of the storms
on Monday could become strong to severe, and will bare monitoring
over the next few days.

Discussion: Progressive zonal flow with embedded shortwaves will
transition to a more amplified ridging patter as an area of high
pressure builds across the Intermountain West and shifts east toward
the Front Range. Associated with this ridge, a strengthening thermal
ridge expands and moves into SE Wyoming by Friday. The bulk of the
warmest air will lag behind but temperatures should easily eclipse
80F for most everyone on Friday. By Saturday, models are in good
agreement in shifting this thermal ridge across the Front Range with
H7 temperatures surging into the 15-20C range Saturday afternoon,
with full sun, temperatures will rapidly climb for areas east of the
Laramie Range and in the Nebraska Panhandle. By Sunday, most models
suggest a breakdown of the ridge axis allowing for a more west to
northwest flow aloft to develop. Moisture in the lower level will
begin to increase and should be enough to initiate some diurnal
convection Sunday afternoon. Cloud debris and the cooler NW flow
aloft should be enough to keep temperatures from warming too much
Sunday afternoon, but outside these areas, temperatures could sore
into the mid to upper 90s, especially across the southern Nebraska
Panhandle.

Heading into Monday, the ridge shift east allowing for the next
storm system to dive south across Montana and move east through
Wyoming. At the surface a cold front will move through the region
Monday night. With a warm, and unstable airmass ahead of the frontal
boundary and with better dynamics aloft, scattered to widespread
showers and thunderstorms may develop in the warm sector, ahead of
the frontal boundary Monday afternoon. These storms could become
strong to severe. As the front moves through, CAA will spill into
north central Wyoming and spread south and east. Some breezy
conditions may accompany this front and much cooler temperatures are
expected on Tuesday, but temperatures will be in the 70s.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1133 AM MDT Tue Jun 7 2022

VFR conditions currently across area terminals with one exception
being KSNY as low clouds have continued to stick around through
late this morning. Latest satellite imagery continues to see
thinning of low clouds around KSNY, but could see IFR ceilings
continue through 19z. Scattered thunderstorms will develop early
this afternoon along and east of the Laramie Range into the
Nebraska Panhandle. Kept sites at VCTS for now, but many need to
monitor latest radar trends and AMD to include TSRA where needed.
This could be more likely across Nebraska Panhandle terminals
after 21z as storms potentially develop into a line/cluster.
Gusty, erratic winds are likely with storms with the main threat
being large hail. Storms will mostly move east of the area by 01z
this evening as skies begin to slowly clear overnight.

&&

.FIRE WEATHER...
Issued at 215 PM MDT Tue Jun 7 2022

Cold front/dry line...currently located along the Laramie Range is
pushing east this afternoon. It will kick off showers and
thunderstorms through the late afternoon and early evening. Storms
east of this line likely to be severe with large hail and damaging
winds. Severe Thunderstorm Watch in effect through 7PM this
evening. Drier and warmer weather for Wednesday into the end of
the week. Fuels are green...so fire weather concerns are minimal.
Still looking at very dry afternoon humidity across Carbon and
Albany Counties...but with these green fuels...fire concerns
should be kept at bay.
