Area forecast discussion, Feb 9, 9:25 AM MST, 5 hours 37 minutes before
Area Forecast Discussion
National Weather Service Salt Lake City UT
925 AM MST Sat Feb 9 2019
.SYNOPSIS...A weak storm system will pass through the region today.
A second stronger and colder storm system will impact much of
Utah Sunday into Sunday night, then continue across northern Utah
Monday. The active pattern will continue across the area later in
the week as a new storm system crosses the state on Thursday.
&&
.DISCUSSION...
A weak wave continues to approach from central California, ejecting
northeast as a deeper closed low descends off the Pacific
Northwest coast. This wave will bring the passage of a cold front
as it passes overhead late this afternoon and this evening. Ahead
of the cold front, non-inverted areas will see the potential for
gusty winds especially southern and central Utah. Northern closed
valleys which have a deep snowpack will struggle to warm up once
again. By sunset, there is a potential of minor valley/bench
accumulations, with up to 2 inches of snow in the mountains.
Afternoon package will focus on tomorrow's cold front and the
subsequent trough passage Sunday night into Monday morning.
&&
.PREVIOUS DISCUSSION...
A decaying shortwave moving into central California early this
morning will eject quickly to the east-northeast as a much
colder/stronger upper low drops south along the Pacific Northwest
coast. The ejecting shortwave will still have enough
thermal/dynamic support for lift to generate some light snow
across western/northern Utah this afternoon and evening.
The aforementioned upper low will turn east into Oregon/northern
California later today, then continue east and evolve into an open
trough as it cross the Great Basin Sunday through Sunday night.
The well-defined surface cold front associated with the upper
trough will reach far northwest Utah Sunday morning. This front
will strengthen a bit as it crosses northern Utah through mid-
afternoon. Strong low-level frontogenic forcing, increasing
dynamic support from the advancing trough and an upper jet segment
over northern Utah will generate fairly strong convection
concentrated along the near 700mb baroclinic zone late Sunday
morning through the afternoon.
Convection will weaken as a bit as the main trough moves across
the state Sunday evening. The areal extent of precip will by and
large decrease during the evening behind the trough passage. The
one exception will be across the far north where moist low-level
warm advection will redevelop underneath the mid-level cold pool
late Sunday night/early Monday. This synoptic situation would be
favorable for steady snow and significant accumulations over the
northern Wasatch range and adjacent valleys. Have issued a winter
storm watch for the northern Wasatch range and the Cache valley
beginning Sunday afternoon with the frontal passage and continuing
through mid-evening Monday. Farther to the south the southern
Wasatch and western Uintas will also be in favorable setup to
continue accumulating snows, though amounts looks to be slightly
less and the duration of the event somewhat shorter than points
to the north.
A low amplitude ridge moving east across the region will nudged
precip north of the state by late Monday night. Increasing low-
level southwest flow aloft will bring somewhat warmer air into
southern/central Utah Tuesday. Looking at warmer temps Tuesday
for the southern/central portions of the state, with the north
staying a bit cooler due to new snow cover and less warming aloft.
Weak ridging in place will quickly break down with another trough
feature moving into the Great Basin from the West Coast late
Wednesday. Model guidance continues to be out of sync timing-wise
and location for the next few troughs. However, compared to 24
hours ago, the Thursday storm system does seem to be within 3-6
hours of one another among model solutions and the location of the
trough passage is much more lined up. Confidence is increasing in
this system. Winds ahead of the trough should be elevated out of
the southwest with once again warm advection and a good tropical
moisture tap before the northwest frontal passage shift later on
Thursday. Temperatures aloft once again cool drastically behind
the front to near -16C. Model guidance continues to be all over
the place for specific details, but the system as a whole looks
fast moving.
Looking bigger picture minded, the extended forecast period is quite
active and remains that way. There remains brief ridging in between
storm systems depicted by forecast models but the period of time
between waves is becoming shorter and shorter as we head into the
last half of February.
