Area Forecast Discussion
National Weather Service Grand Junction CO
540 PM MDT Mon Apr 11 2022
.SHORT TERM...(Tonight through Tuesday night)
Issued at 402 PM MDT Mon Apr 11 2022
The forecast remains on track early this afternoon. GOES-East
satellite imagery shows that the well advertised potent mid-level
closed low has slammed into the Pacific Northwest and is
currently residing over Washington and Oregon. Intense large scale
ascent is noted within the diffluent flow downstream of the low
in the form of rapidly developing and expanding cloud cover over
much of the Intermountain West. South of the low, a strong cold
front can be seen via visible and infrared imagery with several
lightning strikes detected in the last few scans. All of this to
say... we're dealing with a very strong and dynamic spring storm
with most of the Western Slope under threat of hazards ranging
from very strong winds, heavy snow, and potential freeze concerns
due to much below normal temperatures. We'll break down each
threat individually below. Hang on for the ride.
First we'll start with winds. As the previously mentioned closed
low slides eastward into the northern Intermountain West, it will
become negatively tilted. As this occurs, the thermal, height and
pressure gradients will tighten and support a belt of 120kt+
250mb west to southwesterly winds aloft. Farther down in the
atmosphere at 700mb, southwest winds will be on the order of 60
to 75kt this evening and overnight as they round the base of the
trough and punch into eastern Utah and western Colorado. These
kinds of speeds at 700mb are incredibly rare for this time of year
and are greater than the 99.5th percentile. While surface winds
have been increasing this afternoon and several gusts of 35 to 55
mph have already been measured... the worst of the wind is yet to
come. In most cases, wind speeds will typically peak late in the
afternoon and early evening before diminishing after the sun
sets. That will NOT be the case this time. As the strong cold
front approaches the CWA from the northwest, southwest winds will
only increase further across most of the region later this evening
and overnight. Sustained winds of 25 to 35 mph will be common
with speeds of 40 mph not ruled out. Gusts in the valley will
range between 40 and 55 mph with 60+ mph not ruled out... with
gusts up to 65+ mph likely in the mountains. After looking at the
12Z HREF mean/max wind gusts in addition to hi-res forecast
soundings... it became quite apparent that winds needed to be
bumped up even more. We strongly considered upgrading the Wind
Advisory to a High Wind Warning... but ultimately decided to hold
off and let the next shift make that call depending on how real
time observations play out this evening. Regardless, please
understand that tonight's winds will not be your typical run-of-
the-mill winds. These winds will be capable of blowing around
unsecured objects, causing damage to trees and perhaps even
causing damage to power lines (which can lead to scattered power
outages). The strongest winds will occur around midnight tonight
(+ or - a few hours on either side) and will subside in most areas
after the front moves through by 6 or 7 AM Tuesday morning.
Next, we'll detail the precipitation/winter side of things. Not
only will this system have plenty of dynamical forcing to work
with, but it will have an abundance of moisture as well. It may
take some time this evening and early on overnight for this
moisture to reach the surface, but PWATs are progged to be over
150 to 200% of normal. That's a lot of moisture for this time of
year. Out ahead of the cold front, showers will first develop
across the higher terrain of the eastern Uintas and in the
mountains along the Continental Divide. As the front approaches,
showers will become more widespread and more intense. Snow levels
will initially be fairly high, but will crash to all valley floors
by Tuesday morning as much colder air surges in behind the front.
Thus, expect rain showers to mix with or briefly change to snow in
the lower valleys (and even in the lower desert valleys) with all
snow expected in the higher valleys and of course the mountains.
With the exception of the eastern Uintas, snow is very likely to
be heavy at times in the mountains with CAM guidance indicating
the potential for snowfall rates of greater than 2 inches per hour
(overnight in the central and northern Colorado mountains,
towards daybreak in the San Juans). This isn't surprising given
that the environment in play is very conducive to snow squalls &
heavy snow with steep lapse rates and 100-250 j/kg of CAPE to play
with. Overall, snow totals haven't changed much from previous
forecasts and are expected to be in the trace to 1" range for the
lower desert valleys, 2 to 4 inches in the high valleys of
northwest Colorado, and 4 to 6 inches for the eastern Uintas. In
the Colorado mountains, snow totals of 6 to 12 inches are expected
for most with 12 to 18 inches possible above 9 to 10k feet. These
snow amounts on their own aren't anything to write home about,
but combined with the winds... yeah, that's why we have a Winter
Storm Warning in effect. With wind gusts up to 65 mph (possibly
exceeding 70 mph above timberline), near blizzard and whiteout
conditions are likely with icy and snow-packed roads. Travel over
the high mountain passes will be extremely difficult if not
impossible. If you have to travel overnight, make sure you have
emergency supplies handy... or better yet, make alternative plans.
After the front moves through late tonight and early tomorrow
morning, snow intensity will wane and become lighter. That said,
favorable moist orographic upslope snow will likely continue for
the Divide mountains through most of the day with improving
conditions expected elsewhere.
Finally, we'll talk about the much below temperatures and
potential freeze concerns. Behind the cold front, 700mb
temperatures will plummet to around -15C by late Tuesday night and
early Wednesday morning. This is incredibly cold air for this time
of year. High temperatures, as a result, will be a good 15 to 25
degrees below normal. A stark contrast to the 60s and 70s
experienced today. As our system departs later on Tuesday and
skies attempt to clear Tuesday night, temperatures will fall well
below freezing and introduce yet another round of freeze concerns.
Given that the growing season is underway across the Grand Valley
and Grand Flat regions, a Freeze Watch was issued with this
afternoon's package to give a heads up to those with agricultural
interests. If sensitive vegetation didn't see much of an impact
from the freezes of a week or so ago... this one might be the one
to do it. Make your preparations now.
.LONG TERM...(Wednesday through Monday)
Issued at 402 PM MDT Mon Apr 11 2022
Unsettled weather continues after the trough axis shifts east of
the Divide Wednesday morning. There may be a lull, or decrease in
coverage of mountain showers by mid-morning. However, isolated
convective bands will flourish again by the afternoon, favoring
the central to northern mountains where SBCAPE climbs to 250 - 350
J/kg. By this time, the upper level jet on the downstream side of
the trough will completely encompass the CWA. In addition, dry
air near the surface advects into the region from west to east.
The combo of a well mixed boundary, strong upper level winds and
instability all point to another gusty afternoon, especially near
convective showers. Steering winds tilt to the west/northwest as
the jet traverses the region, with afternoon gusts ranging from 30
to 40 mph. Fortunately, in post-frontal conditions, convective
dynamics and diurnal mixing weaken after sunset, allowing winds to
decrease once the surface decouples. Very light showers are
expected by this time, with the Elkhead, Park and Gore Ranges
holding the best chance at receiving any lingering snow.
Temperatures on Wednesday will be stuck well below normal in the
wake of today's system, however a warming trend is on tap for the
remainder of the week.
Relatively zonal flow sets up aloft on Thursday, with a subtle
transient ridge sliding over the Northern Rockies. This will
generally result in a break from precipitation, however, a
persistently strong pressure gradient overhead indicates
redevelopment of gusty surface conditions each afternoon through
the end of the week. The next Pacific NW trough is progged to send
a pulse of energy across the Northern mountains Thursday evening
into Friday. Most of the region remains dry due to abnormally low
PWATs (20 to 50% of normal) stretched over the West Slope.
However, the northern tier of the forecast area may squeeze out
some light precipitation from the southern extent of this system.
Otherwise, zonal flow resides dry weather across the CWA through
Friday.
Ensemble clusters begin to reveal discrepancies with regard to
the following system progged to move inland over the weekend. The
00Z mean cluster analysis shows a weakening low rolling across the
Northern mountains Saturday into Sunday. This scenario would lift
the bulk of energy and moisture tied to the low north and east of
the CWA. Any southern shift to the storm's track would be more
beneficial for western Colorado and eastern Utah to receive any
measurable precipitation. Ridging does become more apparent in the
wake of the weekend's system, indicating a warming and dry trend
beginning next week.
&&
.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)
Issued at 540 PM MDT Mon Apr 11 2022
Gusty winds for all TAF sites remain the main concern through
Tuesday morning. Gusts will increase to 45 to 55 kts heading
towards 06Z. LLWS will be a concern at most TAF sites with such
strong winds aloft. Winds will diminish after 15Z Tuesday but
gusts of 20 to 25 knots are still expected to persist through
Tuesday evening. Clouds thicken and lower through the night with
ILS breakpoints likely being reached for several mountain TAF
sites this evening. Snow and rain becomes likely as the front
moves through causing CIGS to drop further while visibility falls
as snow showers intensify resulting in MVFR conditions with the
potential for brief IFR/LIFR conditions driven by stronger
convective cells. Isolated lightning is possible as well. Showers
will favor the higher terrain along the Divide after 18Z Tuesday
with CIGS gradually recovering from west to east.
