.DISCUSSION...A seasonably weak and weakening cold front will be
the dominant driver of our weather on Saturday into early Sunday.
This includes chilly mornings on the east side, clouds on the west
side, and occasional light rain for the coast and across Douglas
County. High pressure will follow later Sunday through Tuesday
with a drying trend, and warming trend of high temperatures.
Wednesday and Thursday will most likely be days of gradual
transition with the approach of a broad trough. The trough looks
to be the most prominent feature late in the week into next
weekend with the next rain chances for our area.
A few showers are lingering over the higher terrain from the
Cascades eastward this afternoon, mainly in Modoc County.
Meantime, the next disturbance is offshore from northern Oregon
and will move south-southeastward. This weak cold front will
produce an influx of low clouds into southwest Oregon tonight,
with a chance of showers at the coast later this evening then
inland across Douglas County late tonight. The front will weaken
while making little forward progress during Saturday. This will
continue the shower chances north of the Umpqua Divide with cloudy
skies across the west side. The rest of the west side will have a
cloudy but dry Saturday. Meantime, east side clouds will diminish
tonight, then mid-level clouds increase for the Saturday day-time
hours.
The Freeze Watch for east side valleys late tonight into Saturday
morning has been upgraded to a Freeze Warning. This will be the
only freeze warning issued for east side valleys, with this being
considered a season ending event and normal low temperatures now
approaching freezing. Freezing temperatures are also likely each
morning from Sunday through Tuesday. Low temperatures during the
weekend are expected to reach freezing, but the warmest portions
of the area will be near freezing. On the coldest morning of this
episode, a hard freeze is expected for all of the area on Monday.
Easterly winds late Sunday into Tuesday will be light, with warm
afternoon temperatures and clear skies. Models historically have
difficulty with determining where wobbly, broad, closed upper
level troughs will track. The Wednesday into the weekend trough is
no exception, with the additional complicating factor of a second
trough also tracking southeastward out of the Gulf of Alaska late
in the week. The Wednesday into Thursday period has the highest
probability of being characterized by increasing high clouds and a
southerly flow, with a low, but highest probability of light
showers for the coast. By Friday, day 7, and even more so for next
weekend, an episode of cool, wet weather is an increasing
probability. -DW

.AVIATION...03/18Z TAFs...IFR/LIFR along the coast will break
up with VFR developing this afternoon. Lower conditions
including IFR/LIFR will return tonight with a little light
rain/drizzle, especially from around Gold Beach/Port Orford
northward. This will last through most of Saturday morning.
Areas of moderate to heavy rainfall are impacting portions of
Modoc County (near Alturas) and also southern Lake County east
of Lakeview with MVFR ceilings/visibility. Rain should taper
off to showers this afternoon with conditions improving to VFR.
Elsewhere inland, any ceilings should lift to VFR this
afternoon. Some MVFR and terrain obscuration will redevelop
tonight into Saturday morning, especially west of the
Cascades with some light rain possible near and north of the
Umpqua Divide. Foggy areas could develop in the valleys/basins
of norCal and over the East Side where it has recently rained.

along with steep, hazardous seas. Conditions should improve early
next week. -Spilde
