Discussion The first round of precipitation is diminishing as
the responsible upper wave exits eastward. Showers will continue
with the focus of development in the mountains. Lower valleys will
see snow or rain snow mix for the rest of today but little if any
accumulation as temperatures warm above freezing. The second round
of precipitation will start in earnest this evening. Have updated
the forecast for today, mostly to lower pops across southern zones
and adjust the qpf. Will updated the hazard products with the
afternoon package.

Aviation Snow showers through the weekend will produce periods
of ifr MVFR. Significant accumulations are expected in the
mountain locations through Tuesday. Snow levels rise to 3000-4000
ft by Sunday afternoon, so the lower valley locations will switch
over to rain. Surface winds: sse 10-15 kts, with gusts to 30 kts
in SE or. Winds aloft near 10 kft msl: west at 40-50 kts.

Prev discussion
Short term... Today through Monday... Models are trending a little
higher in terms of QPF and snowfall for this large and prolonged
winter weather event. All current advisories and warnings will
remain in effect. Snowfall in the lower elevations may last a
little longer than previously forecast as the models are also a
little colder in lower elevations. However, there will not be
enough to warrant a new advisory in any lower elevation zones.

As indicated in previous discussions, this storm will arrive in
two main sections... An initial one today and a stronger and wetter
one Saturday night through Tuesday, and perhaps into Tue night.

Focusing on the initial storm today, we will see snow increase
through the morning in most areas. After a brief lull late this
afternoon into early evening, a long-lasting westerly fetch of
moist but still cold air will move into the region. Pw values
remain at or above the 60th percentile from Sunday evening through
the end of the event. Upper level flow will slowly back to wsw by
Monday morning, and warming lower levels from Sunday morning into
Sunday afternoon will change snow to rain below around 3000 to
4000 feet during the day Sunday. Moisture will continue unabated
into the mountains through at least Monday, with the latest
snowfall estimates even higher than previous. The mountains will
see 2 to 4 feet of snow through Tuesday, with valley locations
getting between 0.5 inches and 3 inches through Sunday around
noon. Winds will increase across the area Saturday afternoon and
remain relatively high through Monday, producing blowing snow and
making what will already be a difficult situation even worse.

Blowing snow was added to the forecast wherever wind gusts were
greater than or equal to 20 kts and temperatures were 29 or below.

Long term... Monday night through Friday... Good model agreement
is showing the active weather pattern will continue through the
extended period. Models all show that the upper low off the pac nw
coast continues the moist southwest flow into the region. Ahead
of the upper low, models continue the trend of building a weak
upper ridge over the idaho montana border. This allows
temperatures to warm to near or slightly above seasonal normals
through the week. Snow levels are expected to rise above valley
floors across the snake river plain region for the week. By the
end of the week, models diverge on the progression of the upper
low. The GFS brings it straight inland, whereas the ecm lifts it
northward (riding over the weak ridge) and absorbs it into the
mean flow Friday. At this time, the ecm is preferred due to the
upper ridge axis across the southern great basin. This keeps a
warm and moist pattern going into the weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
