What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Grand Junction, CO wrote its last area forecast discussion before this winter storm warning went out at Dec 11, 10:11 PM MST, 5 hours 58 minutes earlier.
Area forecast discussion, Dec 11, 10:11 PM MST, 5 hours 58 minutes before
Area Forecast Discussion
National Weather Service Grand Junction CO
1011 PM MST Wed Dec 11 2019
.UPDATE...
Issued at 958 PM MST Wed Dec 11 2019
Satellite, webcams and observations from the Vernal Regional
Airport show dense fog persisting in the Eastern Uinta Basin late
this evening. HRRR guidance and other high res models allow this
trend to continue through mid Thursday morning. Therefore, a Dense
Fog Advisory has been issued through 10 AM MST Thursday for
UTZ024.
UPDATE Issued at 905 PM MST Wed Dec 11 2019
A multi-day event will begin to unfold tomorrow afternoon and
evening for the northern and central mountains where Winter
Weather Advisories have been issued. There is fair model
agreement that there will be a break or at least a decrease in
the snowfall rates Friday evening. The next system, which is
stronger, is expected to arrive early Saturday and track over the
area on Sunday. This system has the potential to bring significant
snowfall to the mountains across the region therefore a Winter
Storm Watch has been issued for a majority of the mountain ranges.
Some model guidance is showing the possibility of banding across
the area. There is still a good deal of uncertainty with the
exact strength and track of this second storm, which will dictate
where the heaviest snow will fall. Stay up to date with the
latest Watches, Advisories and Warnings.
&&
.SHORT TERM...(Tonight through Thursday night)
Issued at 352 PM MST Wed Dec 11 2019
A fast moving, mid-level trough will cross the CWA this evening.
Very little moisture is tied to this disturbance, but some shower
activity will track across the region as the trough axis passes.
Precipitation developed over the eastern Tavaputs this afternoon and
showers are expected to continue east across western Colorado this
evening. Additional precipitation will favor northern Colorado
Mountains along the Divide, including the Elkhead, Park and Gore
Ranges. Otherwise, expect mid to high level clouds spreading across
the region as this disturbance passes east of the Rockies tonight.
Some light orographic snow showers will linger along the Divide
tonight, although only light localized accumulations are expected.
Pacific moisture begins to filter into the region Thursday morning
as an upper level jet enters eastern Utah. Residual moisture and
west-northwest flow will favor snow showers materializing along the
Elkhead and Park Ranges first Thursday afternoon, spreading south
along the Divide. Initial showers will be lighter ahead of what will
be the main surge of moisture, lasting well into the weekend...More
on this is discussed below, combined with the long term...But this
plume of moisture, originating from an atmospheric river, is
projected to reach the Colorado Rockies Thursday evening. Elsewhere,
temperatures will see little change on Thursday, remaining above
normal for most locations.
.LONG TERM...(Friday through Wednesday)
Issued at 352 PM MST Wed Dec 11 2019
Snow showers will increase in coverage across the western
Colorado mountains as an upper level jet crosses the region on
Friday. The northern and central mountains will be favored at the
beginning of this event where 5 to 10 inches of snow accumulation
is possible, with locally higher amounts up to 15 inches by
Friday evening. Have decided to hoist a Winter Weather Advisory
for Colorado zones 4 and 13 starting Thursday afternoon, with
zones 10 and 12 joining Thursday evening, all continuing into
Friday evening.
A brief lull in activity is possible Friday night as winds shift
aloft. Another mid level trough digging into the Pacific
northwest will shift the jet maxima over the CWA and turn flow
from the northwest to the west. This transition and increased jet
dynamics will enhance Pacific moisture transported into the southern
mountain ranges Saturday afternoon. Cooler temperatures will also
filter into the region from north to south as the system deepens,
which may allow showers to transition to snow across the lower
valleys.
The PacNW trough will deepen over the Great Basin Saturday night
into Sunday, which will finally push the jet aloft east of the
Rockies. As this progresses, a cold front will cross the entire CWA
bringing significantly colder temperatures regionwide for Sunday.
Precipitation is expected to favor the southern and central
mountains with the frontal passage, where convective showers could
create brief periods of heavy snowfall across the San Juans.
Northwest flow returns on Monday, allowing showers to slowly taper
off...although, orographically driven showers in northwest flow tend
to linger longer than models pick up. Dry and colder conditions
prevail Tuesday with highs expected to be several degrees below
normal.
&&
.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1009 PM MST Wed Dec 11 2019
Light and variable winds will persist across much of the region as
mid and high level clouds continue to increase this evening ahead
of an approaching disturbance. Dense fog looks to continue at VEL
through the overnight. Isolated snow showers will increase over
the northern Colorado mountains around 12Z Thursday before
coverage spreads to the central mountains. VFR conditions will
persist at all TAF sites through the period but ILS breakpoints
will begin to be met at HDN, RIL, EGE, ASE by 18Z as CIGS lower.
