Area Forecast Discussion
National Weather Service Medford OR
259 PM PDT Wed Nov 3 2021
.SHORT TERM...Today through Friday night...Low pressure continues
to move eastward over the offshore waters, and south to north
pressure gradients are tightening. This means south winds will
increase through the afternoon and overnight hours in most places
as the low gets closer to the forecast area. Winds are expected to
peak overnight into Thursday, with gusty winds lasting longest
east of the Cascades. Per the GEFS ensemble mean, these winds are
significant for this time of year, but we've already had stronger
"south wind systems" so far this season. Potential tree damage
and power outages, especially in the High Wind Warning areas
(coast, windiest areas east of the Cascades) will be the highest
impact from this storm. Rainfall will be significant at the coast
and in portions of Siskiyou County, courtesy of the southerly flow
that is accompanying this storm system. Rain rates will approach
a half inch per hour at times tonight, but they are not expected
to reach critical criteria for flash flooding/debris flows at the
wildfire burn scars. Additionally, we've communicated with partner
agencies about the area along Highway 97 that has had issues with
debris flows...and that we expect the heaviest rainfall to be
tonight in that area.
Lightning has been observed over the coastal waters this afternoon,
and we expect thunderstorm chances to continue into Thursday morning
over the waters, coast, coastal valleys, and inland to areas
generally west of Roseburg. Given the strong winds aloft, there
may be strong winds with some of these storms. Conditions will
dry out some late Thursday, and the next front will arrive Friday.
Precipitation will not be as heavy with this system as the one
upcoming tonight, and winds won't be as strong.
.LONG TERM...Saturday through Wednesday...Guidance is in good
agreement that the unsettled pattern continues through the extended.
Another wet and breezy front will move through the area on Saturday.
Rain will be heaviest, as usual, over the coastal mountains with
downsloping winds limiting interior valley accumulations. Not
expecting major impacts from wind, but we will probably see advisory
level winds in the usual spots (Shasta Valley, East Side).
There will be a relative break in the action Sunday, but a stronger
front appears to be in the offing for early next week. This looks
like a more long-lived precipitation event with soaking rains
possible from later Monday all the way into Wednesday as a strong,
zonal, upper jet remains aimed at our area. Strong pre-frontal winds
are possible with this system Monday, but much depends on the track
of the associated surface low pressure. At this time, the
preponderance of the evidence suggests low pressure coming in right
over us or just south of us, but confidence in that level of detail
is low.
The final note about next week's system is that it looks a bit
colder than recent storms, so mountain snow may be an impact. Snow
levels are expected to start out around 5000 feet and then lower to
at least 4000 feet by Tuesday. Thermodynamics even suggest the
potential for some upslope snow in the Mt. Shasta City area by
Tuesday morning. Again, the devil will be in the details, and this
is still 5-7 days out. But it is advisable to keep an eye on early
next week as the potential for impacts (wind, rain, and maybe even
snow) is increasing. -Wright

.AVIATION...03/18Z TAFs...Winds will increase ahead of the next
front, and breezy to gusty winds will be expected along the coast,
in north-south oriented valleys west of the Cascades after 00Z, and
along a broad swath of area east of the Cascades. Precipitation,
along with lower flight conditions and terrain obscurations, should
begin along the coast this afternoon, spreading to the Cascades by
evening, then to all of the forecast area by the end of the TAF
period. Generally, expect VFR for most of the area except for in
areas of moderate to heavy precipitation. In theses areas, terrain
obscuration will also occur. -Schaaf/BPN
&&
.MARINE...Updated 200 PM PDT Wednesday 3 November 2021...South
winds will increase through this afternoon as a strong surface front
approaches the region. As the front approaches the coastline, the
parent surface low is expected to deepen and passes just along 135
W. A classic coastal jet scenario is expected to result, with strong
south gales and very steep wind-driven seas likely late this
afternoon through Thursday morning, followed by a large west swell
Thursday into Friday. An active storm pattern, including the next
front arriving Friday morning, and various large swell trains, will
continue through the weekend and into next week. -BPN/Schaaf
