Area Forecast Discussion
National Weather Service Medford OR
249 AM PDT Sat May 13 2017

.DISCUSSION...A broad upper level trough remains over the Pac NW
today with a pool of cold air aloft that will provide for enough
instability for mainly afternoon and evening showers. In spite of
very cold air aloft yesterday, we did not see as many lightning
strikes. The cold pool today is not as high as yesterday and
should result in locally moderate showers.

On Sunday the trough remains but weakens a bit. We can't rule out
a chance of showers but they should be confined mainly in upslope
flow and over the mountains. Monday could see more sunshine but
with NW flow aloft we should still see upslope showers. However
both the ECMWF and the GFS bring in another closed low into
Vancouver Island by Monday evening, with a surface front down to
northern Oregon. As a result rain chance increases at the coast
and in the Umpqua Basin by Monday afternoon but could hold off in
the Rogue Valley until Monday night. Both models are remarkably
consistent with the GFS slightly slower but the main synoptic
looks are very similar. Confidence is high that we will see a
return to wet weather Monday night into Tuesday.

Snow levels this afternoon will range from 4500 to 5500 feet so
Crater Lake should see a few more inches of snow. On Monday snow
levels could rise to 5500-6500 feet from the Cascades eastward,
but could crash to around 4000 feet Tuesday afternoon. Crater
Lake, Mount Ashland and Mount Shasta could see 5 to 8 inches of
new snow Monday night through Tuesday night. The Warner mountains
could see 4 to 6 inches of new snow during this time.

On Tuesday the GFS is hinting at very strong winds across all of
our forecast area. This appears to be an outlier but bears
watching. I have increased wind speeds for Tuesday but not to the
extent of the GFS. /FB

&&

.AVIATION...13/06Z TAF CYCLE...Scattered light to moderate showers
will continue across the area tonight. Cigs/vis will be generally
VFR outside of showers, but areas of MVFR/IFR are possible along the
coast and in the Umpqua basin, especially within and near showers.
Rides into area terminals may be bumpy due to weak low level wind
shear, convection, and weak mountain wave turbulence. VFR should
return to most areas by late morning. -BPN

&&

.MARINE....Updated 800 PM PDT Friday 12 May 2017...Expect moderate
to heavy showers, isolated thunderstorms, and gusty southwest winds
through this evening as a cold front moves through. Conditions will
generally be of small craft advisory level except for a period
overnight where the combination of increasing west swell and
residual wind waves will produce very steep seas. Seas will be
highest beyond 5 NM from shore and north of Port Orford. A weaker
front will follow on Saturday with diminishing seas remaining steep.
Showers will diminish on Sunday while approaching high pressure
produces increasing north winds. The northerly winds will be
strongest Sunday afternoon and evening south of Port Orford,
especially south of Gold Beach. Another cold and wet frontal system
is likely to arrive on northwest flow Monday. High pressure will
return late Tuesday with northerly winds becoming strong again in
the southern portion of the waters. /BPN
