Area Forecast Discussion
National Weather Service Medford OR
240 PM PDT Mon Apr 8 2019
.SHORT TERM...Water vapor imagery is showing the atmospheric
river (AR) finally getting a push inland as the upper trough
offshore moves eastward, so the end is in sight. Broad, moist WSW
flow will gradually be replaced by moist WNW flow aloft as the
upper trough moves in tonight and Tuesday.
As forecast, this AR brought copious amounts rainfall to portions
of Curry and western Josephine County with the latest 2-day
rainfall in those areas averaging 6 to 10 inches with locally more
than a foot in the coastal mountains. 3 to 6 inches of rain fell
across most of Coos and Douglas Counties with 1 to 3 inches here
in the Rogue Valley. The sustained heavy rainfall rates at the
coast have mostly ended, though showers will continue and there is
still a risk of isolated lightning strikes through tonight. The
main band of rainfall associated with the AR will push across the
Rogue Valley/Cascades/Siskiyous this afternoon/evening, and then
shift southeastward across the rest of the forecast area
overnight. It should exit our area completely by early Tuesday
morning. Flood waters will take some time to recede, so we are
maintaining areal flood products through this afternoon and into
tonight for many areas. Streams and creeks will be the first to
come down, but we expect some of the main stem rivers to continue
be near or above flood stage tonight through Tuesday. Please refer
to the "point and click" map on our home page for more
information...or also the "Rivers and Lakes" section for specific
river/lake/drainage information.
Meanwhile, the upper trough will move onshore tonight and
then through the area on Tuesday. This will keep showers going,
especially across the north and west facing terrain areas, where
upslope flow will be maximized (Cascades, Siskiyous, Umpqua
Divide). Snow levels will drop to around or even a little below
4000 feet by Tuesday morning, so if there are sustained showers,
there could be some minor snow accumulations, especially above
5000 feet in the Cascades. Any road accumulations though won't
last long. While there could still be brief downpours with the
showers Tuesday, we aren't expecting the sustained rain rates like
we've seen the past 48 hours. Breezy NW winds are likely Tuesday
afternoon, with good mixing, a nice west-east pressure gradient
and downward transport expected on the back side of the trough.
Gustiest winds are likely over the East Side, but also in the
Shasta Valley and even near Mount Shasta City.
An upper level ridge will nose into the area Tuesday night into
Wednesday, so coverage of showers will diminish and many areas
will dry out, especially across areas south and east of the Umpqua
Divide. It could get frosty in some of the valleys in northern
California Wednesday morning, but not up farther north since
there'll likely be too much cloud cover. The next system will move
in from the northwest Wednesday night with precipitation chances
increasing again, especially across NW sections. -Spilde
.LONG TERM...Extended discussion, Thursday through next Monday. As
over the past several days he GFS and ECMWF operational runs are in
fairly good agreement starting Thursday. As we start Thursday both
are showing a front sliding into the region on the back side of an
upper level ridge well offshore. The GFS has come in line again with
the ECMWF in bringing down a closed low down the backside of the
upper ridge Thursday night into Friday, and with the increased
confidence had raised POPs to likely or greater over most of the
forecast area for that time period. The upper ridge builds in
quickly behind the exiting upper low Friday afternoon, brining a
break in the wet pattern before the ridge flattens and another front
moves onto the coast Saturday morning. A wet pattern remains in
place into Monday, when a stronger system moves in on the left exit
region of a +120 kt jet. This system is indicating as a atmospheric
river event, but much weaker than the current firehouse focused on
our area. Sven

.AVIATION...For the 08/18Z TAFS...Very moist storm moving through
the region providing widespread MVFR weather in areas of rain and
local moderate rain. Cascades and Siskiyous obscured. Western edge
of main precipitation band will move from SW Oregon to SC and SE
Oregon this afternoon into the overnight hours. Drier air with west
to northwest flow in the mid and upper levels will prevail by 12z
Tue with scattered showers and continued MVFR ceilings through 18z.

.MARINE...Updated 200 PM PDT Monday, 8 April 2019. Winds over the
coastal waters will shift to northwest late this afternoon and this
evening behind a cold front. Thereafter through Wednesday high
pressure will anchor between 130W and 140W just south of 40N. A
couple of weak fronts with benign winds will pass through Thursday
and then Saturday. A stronger front looks to arrive with increasing
south winds Monday or Monday night. MTS
