Area Forecast Discussion
National Weather Service Cheyenne WY
706 PM MDT Wed Mar 22 2023
.UPDATE...
Issued at 706 PM MDT Wed Mar 22 2023
Updates were made to the winter weather headlines with the issuance
of a Winter Weather Advisory for the I-80 corridor from the Summit
to Pine Bluffs until midnight tonight. Moderate to heavy snowfall
will be possible this evening with the banded snow showers. One
to two inches of snow is expected, with totals from 2 to 4 inches.
The High Wind Watch for Bordeaux, I-80 Summit and Vedauwoo was
cancelled, and upgraded to a Warning for Arlington until 6 AM
Thursday. Craig-Casper 700/850mb gradients are below 60 meters,
however NAM 700mb westerly flow peaks near 55 kt at 06Z Thursday
as low lifts northeast across south-central WY.
&&
.SHORT TERM...(This evening through Friday)
Issued at 325 PM MDT Wed Mar 22 2023
Active weather continues this afternoon and tonight with a brief
lull expected Thursday. Current KCYS radar loop shows increasing
reflectivity along and south of the Laramie Range towards Colorado
with occasional moderate snowfall along I-25 and I-80. This
activity is ahead of the main upper level disturbance which is
currently located in northern Utah at this hour. This Pacific
disturbance is forecast to lift northeast into Wyoming over the
next 6 hours. Current 12z models have trended a little more
aggressive with dynamic lift, particularly low level lift in the
form of convergence and some marginal frontogenesis along a
slow moving warm front/stationary front along the I-25 corridor.
This is apparent when looking at model consensus regarding low to
midlevel Omega between now (21z) and 03z late this
evening...showing 20-40 ub/s lift along and east of I-25. 700mb
low is expected to develop somewhere across southern Wyoming
shortly and push east northeast across the area, just north of
Interstate 80 tonight. Current winter headlines look good, but
need to monitor areas along and west of the I-25 corridor and
Converse and Niobrara county tonight for some locally heavy snow
bands. Ground temperatures are a little colder than what was
expected since most areas failed to reach the mid to upper 30s
today thanks to a persistent south wind and cloud cover. Can not
rule out a snow squall or two given the convective nature of these
bands of precipitation and with the potential of strong winds as
we head into this evening. So far, no lightning has been detected
this afternoon so will keep the mention of thunder out of the
forecast for now.
The other concern of this small but potent storm is the potential
for locally strong winds behind the disturbance/700mb low as it
lifts northeast and then moves across Wyoming. Winds haven't
increased so far, but do expected winds to pick up shortly as the
stationary front accelerates eastward over the next few hours.
Will keep the High Wind Watch in effect for now due to the
relatively short duration of the event and it was a struggle to
get winds up to Warning criteria tonight.
Potent disturbance moves out of the area early Thursday morning as
another weaker vort max/disturbance rapidly moves across the
central Rocky Mountains. Not expecting much with this secondary
disturbance other than some rain/snow showers through the day.
Winds will be elevated for most of southeast Wyoming, especially
along and west of the I-25 corridor where gusts up to 50 MPH are
certainly possible. With westerly flow, daytime temperatures
should rebound a bit into the 40s to low 50s, but still remain
below average for this time of the year. The brief lull in the
active weather pattern will continue Thursday night with low
temperatures in the teens to mid 20s.
To end the week, models show yet another Pacific system moving
across the Great Basin Region and into Wyoming Friday afternoon.
Ahead of the main cold front, the warmest day of the next seven
will likely be Friday afternoon across the eastern plains with
highs in the 50s ahead of the cold front. Trended high
temperatures towards the ensemble/NBM 75th percentile in these
areas. Cloud cover and the early arrival of the front will likely
keep temperatures in the 30s and 40s west of Interstate 25 before
temperatures drop as the front quickly pushes east and 700mb temps
drop to -15c. Strong winds across the wind prone areas and areas
west of I-25 will likely start late Friday afternoon. High Wind
Watches are possible starting Friday evening as we approach this
event.
.LONG TERM...(Friday night through Wednesday)
Issued at 124 PM MDT Wed Mar 22 2023
Fairly active pattern setting up in the long term forecast, with a
series of disturbances pulsing across the Pacific Northwest and into
the CWA. North to northwesterly flow in the mid to upper levels will
aid in keeping temperatures well below normal, with the ECMWF and
the GFS ensembles in good agreement with daytime highs in the low
30s and overnight lows in the upper teens/low 20s. Ensemble members
have remained consistent with trending temperatures downward through
the weekend, with at or near climatological minimums for the Western
CONUS. Models have also maintained consistency with the general
setup, with only slight variations towards a disorganized closed low
developing across the Intermountain West per the Euro solution and
the shortwave trough per the GFS. Getting some decent POPs and QPF
across the CWA from the NBM blend Friday night into Saturday
evening. However, as the previous shift mentioned, timing/impacts
related to precipitation will remain difficult to forecast due to
how the disturbance will evolve over time as they propagate within
the flow. Therefore, confidence for weekend precipitation will
remain low at this time. In terms of the high winds Friday night
into Saturday afternoon, the NBM v4.1 Probability of Exceeding 41
knots is currently indicating high probabilities for stronger winds
along the Laramie Range and further eastward into Cheyenne. In
addition, 700mb and 850mb Craig to Casper gradients have continued
to increase, showing up to 70+ meters at 12z Saturday morning. All
in all, looking more probable for widespread strong winds,
especially along the wind prone areas and even further eastward
towards the High Plains. By early next week, upper level ridging is
expected to build back into the region, increasing our daytime highs
Tuesday.
&&
.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 539 PM MDT Wed Mar 22 2023
A few bands of moderate snow are currently positioned across the
KCYS terminal, northern Albany County, KLAR terminal, and across
the southern Nebraska Panhandle. Visibility with the band across
KCYS is fluctuating between 1/2 SM and 1 SM. This band will
continue to push northeasterly and bring IFR conditions to KBFF,
KAIA, and KCDR between 01 and 06Z. A band over KLAR is moving
slowly to the east with some snow building south of the terminal.
These snow showers may drop KLAR to IFR conditions occasionally
through 01Z. The band across the southern Nebraska Panhandle will
push to the north northeast and a secondary band, currently over
northern Colorado, will move over KSNY and bring IFR conditions
starting around 03Z. Most hires models have been slow on the
progression of these snow bands so significant timing changes have
been made to the 00Z TAFs. Once the snow bands move out of the
area, most terminals will reach MVFR conditions overnight.
Conditions will continue to improve across all terminals overnight
and into the early morning hours tomorrow.
&&
.FIRE WEATHER...
Issued at 218 PM MDT Wed Mar 22 2023
No fire weather concerns expected for the rest of the week and
through the weekend. Periods of snow, cooler than normal
temperatures, and daytime humidities above 25 to 35 percent will
continue into early next week.
