What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Medford, OR wrote its last area forecast discussion before this winter storm warning went out at Feb 25, 8:02 AM PST, 6 hours 35 minutes earlier.
Area forecast discussion, Feb 25, 8:02 AM PST, 6 hours 35 minutes before
Area Forecast Discussion
National Weather Service Medford OR
802 AM PST Sat Feb 25 2017
.UPDATE...No significant updates were needed this morning, as the
forecast appears to be on track. RADAR imagery is showing very
little in the way of returns this morning, but do not doubt there
are some local light showers occurring in some areas, mainly in
the southern half of the forecast area, but nothing that should
produce any impacts. Focus for the day will be on the Sunday
system, refining the snow amounts, and confirming the areas of
likely impact. For more information, see the previous discussion
below. -BPN
&&
.AVIATION...25/12z TAF CYCLE...Areas of IFR cigs/vsbys over the
west side valleys in low clouds and fog will clear to VFR by late
this morning. Areas of MVFR cigs/vsbys in rain and snow will
return to the west side late tonight with higher terrain becoming
obscured. The remainder of the area will remain VFR through this
evening. Areas of MVFR cigs/vsbys in rain and snow with areas of
higher terrain becoming obscured will develop late tonight. -JRS
&&
.MARINE...Updated 800 AM PST Saturday 25 February 2017...Low
pressure off the southern Oregon coast will move south of the area
later this morning. Southerly winds will become northerly late
this afternoon. Showers will taper off as high pressure builds
in. Tonight through Monday, another cold low pressure system will
move through from the north. This will bring small craft winds
and seas to the area Sunday. The winds will diminish Sunday
night...but steep seas will persist through Monday. Offshore high
pressure will build Tuesday into Wednesday. -JRS
&&
.PREV DISCUSSION... /Issued 356 AM PST Sat Feb 25 2017/
DISCUSSION...The most recent coastal low is pushing to the south,
and it's effects on the forecast area are diminishing. Some snow
is still being observed at Alturas, and about another inch of snow
is expected there before snow tapers off. Some morning fog is
impacting West Side valleys this morning, and there is a Dense Fog
Advisory out for the Umpqua Basin. We expect visibilities to
improve later this morning. Temperatures today should be about 10
degrees below normal under a continued cold air mass.
The third low, and likely most significant, in a string of cold low
pressure systems will swing through on Sunday, and tonight's
forecast efforts have focused on that. Timing, temperatures, and
shower intensity/coverage are critical factors in the forecast
for Sunday. A cold front will bring moderate to heavy
precipitation with it on Sunday from northwest to southeast. We
have kept forecast temperatures below MOS guidance for Sunday
based on thick cloud cover and precipitation expected for much of
the day. Heavy showers at times will bring down the cold air
aloft, so we have forecast snow levels at 1000-1500 feet below
freezing levels. The current thinking is that roadways won't be
covered all day because of any breaks allowing late Feb solar
effects to warm roadways, but occasional snow covered roadways are
likely on the lower mountain passes on Interstate 5
(Sexton/Canyon Mtn Pass) and Highway 199 (Hayes Hill). Colder
temperatures will be more favorable for continual snow covered
roadways in the higher Cascades. For lower valleys like the Rogue,
snow is expected, but we are expecting Sunday afternoon
temperatures to prevent continual accumulation of snow, so we
haven't issued an advisory for Medford, etc. We'll of course
continue to monitor latest data for snow potential there. If
showers continue into Sunday evening, more snow will be possible
in the Rogue Valley. We have issued some Winter Weather Advisories
for the aforementioned expected impacts, and we have continued
Winter Storm Watches for the Cascades foothills where unusually
heavy snow accumulations are still possible above 2500 feet.
After the main batch of precipitation Sunday and Sunday night, most
models show continued shortwave activity in the cold northwest flow,
bringing continued chances for low elevation snow. Much of the snow
will likely impact areas from the Umpqua Divide northward, so the
lower passes of Interstate 5 (Sexton Pass, etc) could still see
winter weather impacts into early next week. Conditions dry out and
warm up late Tuesday into Wednesday. Please see the previous
long-term discussion which is still relevant to the upcoming
weather pattern.
Tuesday through Friday...The operational models are
in pretty good agreement in this time period. The pattern will be
rather quiet with little or no chance of precipitation. A
northwest flow continues Tuesday with increasing 500 mb heights.
The models still show some QPF, but they are not as bullish as
they were yesterday. Even then suspect they are still overdone
given 500mb heights will be on the rise as the upper trough moves
east of our area. However the ECMWF shows weak pva moving in the
northwest flow during the day, so we'll keep a slight chance
mention. Confidence is high it will be dry from next Wednesday
through the end of next week as the storm track shifts well north
of the area. Of note, the GFS shows more of a dirty ridge
scenario, but still keeps all of the QPF north of our area, but it
could mean more cloud cover and slightly cooler afternoon
temperatures.
We could be dealing with an increasing subsidence inversion next
Wednesday through Friday which means the valleys could stay cool and
the ridges milder. -Petrucelli
