Area forecast discussion, Jan 12, 4:21 AM PST, 2 hours 20 minutes before
Area Forecast Discussion National Weather Service Portland OR 420 AM
PST Tue Jan 12 2021
.SYNOPSIS...A quasi stationary front is expected to produce periods
of moderate to heavy rain through Wednesday for the potential for
river, rural, and urban flooding. Strong winds are expected along
the coast today and tonight, with breezy conditions for the
Willamette Valley this evening. Large surf and high tides will
result in hazardous conditions for the beaches and low-lying coastal
areas through Wednesday. Dry weather on Thursday will allow rivers
to recede before the next weaker front that is expected Thursday
night.
&&
.SHORT TERM...Today through Thursday...Rain with periods of breezy
winds are the main weather concerns today through Wednesday coupled
with high surf and minor tidal overflow flooding. A quasi-stationary
front fueled by an atmospheric river of moisture will continue
producing moderate to heavy rain across the region through early
Wednesday morning. Lows moving along the front will result in
periods of stronger winds and enhanced orographic rain. The first
low is occurring early this morning when wind gusts of 45-55 mph
have been observed. Rain was enhanced with this low with the focus
of heaviest rain early this morning is over extreme SW Washington
and NW Oregon.
Rain gages have reported 6 hour rainfall totals between 1.5 and 2
inches across the higher terrain, and at least one station in the
Willapa Hills (WA) reported a half of an inch of rain between 1 and
2 AM. The front is making its way inland this morning and expect
this heavy rain to extend inland to the Cascades and further South
into Oregon this morning through this afternoon.
The next low will produce even stronger winds tonight into early
Wednesday, and have more of a southern focus for the winds and heavy
rain. A high wind warning has been issued for the coast from mid
morning today through midnight tonight to account for the periods of
expected strong winds. There will be a period of gusty winds inland
this afternoon and evening with gusts of 40-45 mph possible for the
Willamette Valley. Models are in good consensus on the front moving
inland Wednesday with rain rapidly ending in its wake Wednesday
afternoon and evening. Forecast rainfall totals from this morning
through Wednesday morning are 3 to 7 inches across the higher
terrain and 1 to 2 inches for the interior lowlands. See the
HYDROLOGY discussion below for hydrologic concerns related to this
atmospheric river event.
Beach hazards will continue through Wednesday, with a combination of
tidal overflow and sneaker wave potential Tuesday and Wednesday, and
a bonus high surf on Tuesday. The forecast total high tide at Toke
Point is 12 feet Tuesday afternoon, and 11 feet Wednesday afternoon.
Higher river levels may contribute to minor coastal flooding around
these high tides.
Colder air will fill in behind the front on Wednesday with snow
levels lowering to around 3000 feet. There is a rapid decrease in
moisture flux when the snow levels lower, and do not expect much
snow production. Wednesday night will be relatively cooler with
minimum temperatures in the mid to upper 30s. Patchy valley fog is
likely late Wednesday night as high pressure builds over the area
and skies start to clear. The high pressure will result in dry
weather Wednesday night and Thursday. East winds will develop early
Thursday morning and increase in the afternoon as the next front
approaches. A Dalles to Troutdale pressure gradient of 5 to 7 mph
could produce 25 to 25 mph winds through the Columbia Gorge and east
Portland metro area. ~TJ
.LONG TERM...Thursday night through Monday...Another front is
expected to move onshore Thursday evening. Precipitable water values
are expected to be around an inch with this front, and models are
forecasting IVT between 250 and 500 kg/ms indicating the possibility
for a weak atmospheric river. The jet dynamics are weaker with this
front, and do not anticipate high rainfall production regardless of
the available moisture. The front should move through the area
rather quickly and over by Friday afternoon with rainfall totals
likely remaining below an inch even across the terrain favored
areas. Snow levels will be at or above 5000 feet and do not
anticipate much if any snow from this front. High pressure rebuilds
Friday night and Saturday for a brief period of dry weather. in the
wake of this front. Models are in good agreement on another non
impressive front Saturday night through Sunday followed by dry
weather next Monday.
~TJ
&&
.HYDROLOGY...Mainstem rivers along the SW Washington and NW Oregon
coasts are rising this morning in response to the heavy rain
overnight. The only river at this point forecast to rise above flood
stage is the Grays River at Rosburg, in which a Flood Warning has
been issued for. Other coastal rivers are currently forecast to rise
above baneful, but just shy of flood stage including the Willapa
River at Willapa, the Naselle River, the Wilson River at Tillamook,
the Nehalem River at Foss, The Siletz river at Siletz, and the
Siuslaw River at Mapleton. The inland rivers will likely see rises
later today as the heavy rain expands across the area, and expect
there will be more flood warnings issued later today.
Besides Mainstem rivers, Small streams and creeks will also rise, and
possibly flood today, and minor urban flooding in poorly drained
areas are possible. Will continue the Flood Watch for the same areas
to account for all of the flooding concerns. The saturated soils will
also likely need to land slides. ~TJ
&&
.AVIATION...An atmospheric river will bring periods of
rain and a mix of primarily IFR and MVFR conditions along the
coast and MVFR and VFR conditions inland. As southerly to easterly
winds temporarily weaken later today, brief IFR conditions are
not out of the question inland. Nonetheless, southerly winds
should strengthen this evening and result in conditions trending
back towards a mix of MVFR and VFR thresholds. There will likely
be a short lived period of IFR to MVFR conditions and gusty
winds just ahead and along a cold front that appears poised to
impact most terminals between 03-09z Wednesday. Expect
precipitation to turn more showery and conditions to trend
primarily VFR after frontal passage.

http://weather.gov/zse
KPDX AND APPROACHES...An atmospheric river will bring periods of
rain and a mix of primarily MVFR and VFR conditions. As easterly
winds weaken later today, IFR conditions are not out of the
question with the continuing rain. Nonetheless, southerly winds
should take hold and result in conditions trending back towards a
mix of MVFR and VFR thresholds. There will likely be a short
lived period of IFR to MVFR conditions and gusty winds just ahead
and along a cold front that appears poised to impact the terminal
between 05-07z Wednesday. Expect precipitation to turn more
showery and conditions to trend primarily VFR after frontal
passage. /Neuman
&&
.MARINE...A front will slowly shift southeastward towards the
region today into tonight. Weak waves riding along this front
will temporarily enhance and decrease winds periodically across
the waters through this evening. A coastal jet will likely
enhance winds within 10-20 NM of the coast by at least 5-10 kt
when compared to winds farther offshore during this time. A
period of storm force wind gusts are ongoing early this morning,
but should temporarily decrease later this morning. There may be
another spike in the winds around midday to early this afternoon
before yet another lull in the winds occurs. However, there are
some suggestions that a final push of winds, potentially the
strongest of the bunch, will occur across the central waters of
Oregon and potentially all the way up to the Columbia River near
the coast. As a result, opted to just extend the Storm Warning
early this morning through this evening to cover this potential
hazard. Otherwise, expect seas to generally be in the 20-25 ft
range through tonight as a longer period westerly swell and wind
waves/fresh swell keep seas elevated.
High pressure will then begin to shift across the waters
Wednesday and Thursday and allow seas to subside below 10 ft late
Wednesday night or Thursday. However, the next front appears
poised to impact the waters Thursday night or early Friday with a
round of Small Craft Advisory level wind gusts. This should
result in seas climbing back into the teens Friday into next
weekend. An even weaker front will be possible over the weekend
before high pressure shifts more squarely over the region early
next week. /Neuman
