Area Forecast Discussion
National Weather Service Medford OR
505 PM PDT Mon Jul 3 2017

The Marine and Aviation sections have been updated...

.DISCUSSION...There have been several forecast problems to solve
today, ranging a broad spectrum from the marine layer, to possible
convection, to dry and breezy winds. One thing does remain
constant and relatively easy to predict, and that is warm
temperatures, which should hover around 5 to 10 degrees above
normal for the duration of the forecast term. For the entire
week,the overall pattern will remain relatively static, with
southwest flow aloft, and surface high pressure offshore.

The marine layer poses problems in terms of sky cover and fog
through the week, with inland pushes stronger on some days than
others. Also, several models are depicting a southerly surge
beginning tomorrow afternoon, which would then spread up the
coast through Wednesday. This surge could bring a more persistent
fog and low cloud layer to the immediate coast into Wednesday
afternoon, but details on the fog and clouds associated with the
marine air are difficult to nail down. Have made adjustments to
the inherited forecast to bring these fields more in line with
typical southerly pushes.

Meanwhile, dry winds will increase during the afternoons,
especially tomorrow and Wednesday within the Shasta Valley and
across the East Side. This has prompted some fire weather
concerns, even moreso given the Independence Day holiday and its
usual associated activities. For more on this, see the fire
weather discussion below.

The risk of convection has been a much more complicated issue, as
incoming moisture, a trigger, and developing instability must all
line up at the right times, and no tow models runs can seem to
agree on any of them. Models are depicting instability developing
in the afternoons Tuesday through Thursday, mainly over the
Cascades, Siskiyous, and across the higher terrain of the Eats
Side. Meanwhile, a somewhat weak push of monsoonal moisture will
gradually work its way into the area beginning Tuesday afternoon.
Most of the moisture should remain to our east, but some could
filter west towards the Cascades. To get the convection rolling,
however, we need a trigger, and one of these could arrive in the
form of a shortwave within the southwest flow aloft sometime late
Wednesday into early Thursday. The timing of this impulse is key,
as if it arrives overnight, it will not be able to fully take
advantage of the instability, but it still may touch of an
isolated nighttime storm. If the impulse arrives during the
afternoon, then more convective activity is likely. For now, have
trended towards a slight chance of thunder over the mountains and
adjusted timing towards the model average, but confidence in this
forecast is low, and changes will almost certainly be needed over
the next several shifts.

Finally, models have been showing a large trough in the
northeastern Pacific making its way onshore this weekend or early
next week, but have been differing day to day in strength and
track. Have kept this in the forecast, illustrated with slightly
lower temperatures and increased cloud cover, but given the
strength of the inland ridge, suspect any impact from this trough
will be minimal, if any at all. -BPN

&&

.AVIATION...03/18Z TAF CYCLE...
VFR conditions all areas this afternoon are expected to persist at
least through the evening. Tonight into Tuesday morning the marine
layer is expected to redevelop along the Coos and Douglas County
coastlines and into the Umpqua Basin to about Roseburg between 09z
and 16Z, but is likely to be brief and patchy due to ongoing
northeast winds near the top of the boundary layer. Confidence is
low to moderate in the marine layer redeveloping. IFR is expected
along the coast with MVFR in central Douglas County. Otherwise, IFR
to LIFR fog and low clouds are expected to develop from south to
north along and near the Curry County coast on Tuesday as a
southerly stratus surge occurs. VFR through the TAF period
elsewhere. BTL

&&

.MARINE...Updated 230 PM PDT Monday, 3 July 2017...
High pressure centered over the northeast Pacific and a thermal
trough along the coast will continue to produce strong north winds
and steep to very steep wind driven seas today. The strongest
winds and steepest seas will be from Cape Blanco southward. The
offshore high will weaken Tuesday allowing the thermal trough to
expand westward over the waters. This is likely to result in a
southerly stratus surge along the Curry coast that is expected to
reach Cape Blanco early Wednesday morning. Winds and seas will
also diminish Tuesday through Wednesday. Fairly calm conditions
are expected Wednesday through Friday. BTL

&&

.FIRE WEATHER...Updated 150 PM Monday, 3 July 2017...A high pressure
ridge aloft will strengthen over the inland region on Tuesday then
remain in place through late in the week. Meanwhile an upper trough
will develop off the coast. This pattern will result in southwest to
south flow aloft with some increasing mid level moisture Tuesday
through Wednesday night.

Gusty winds and low humidities are expected east of the Cascades and
into the Shasta Valley in the afternoon and evening on Tuesday and
Wednesday. Critical fire weather conditions are expected to develop
in the Shasta Valley, Modoc county and in eastern portions of zone
624, including southeast Klamath county and southwest Lake county.
Winds are expected to gust to around 25 to 30 mph on Tuesday and
around 30 to 35 mph on Wednesday. This will combine with humidities
of around 10 to 15 percent in the afternoon and early evening to
create increased fire danger. Other areas east of the Cascades, will
see gusty winds and low humidities but conditions are not expected
to reach critical fire weather conditions.

With this southwest flow pattern also expect increasing mid level
moisture along with weak disturbances. This will result in a slight
risk for thunderstorms to develop in the Southern Oregon Cascades
and into eastern Modoc and eastern Lake counties from late Wednesday
afternoon into Wednesday night. Any storms that develop are expected
to have limited rainfall with them and may have erratic and gusty
winds. Confidence is low on storm development late Wednesday and
Wednesday night due to the absence of significant moisture and
instability for storms.

On Thursday, the risk for thunderstorms is expected to decrease.
However there will continue to be hot and dry conditions inland.
Also gusty winds may continue in the afternoon and evening for the
Shasta Valley and east of the Cascades.

For coastal areas, a strong thermal trough will bring continued
gusty north winds through this evening. This thermal trough will
move inland late Tuesday and expect a change to light or southerly
