Further Details:

We will continue to see persistent troughing over/near the Gulf of
Alaska. This will continue to bring rounds of precipitation across
the region which may result in moderate to isolated heavy rain,
light snowfall, and breezy wind speeds/gusts. A pattern change could
evolve Wednesday of next week as this area of low pressure moves
south off the coast of California through Christmas.

Snowfall through tonight continues to indicate relatively light
accumulations at the forecast elevations and therefore limited
impacts. Rainfall amounts will start to significantly diminish today
after the atmospheric river (AR) comes to an end. While widespread
flooding is not anticipated, there may be isolated areas of nuisance
type flooding as rivers are currently running low. A change in river
stage forecast heights occurred as QPF came down, and Myrtle Point
(South Fork Coquille River) is now forecast to stay just below Minor
Flood stage. It will peak tonight between roughly 4pm and 10pm).
This is the only river gauge to note for this AR as all other gauges
are not forecast to be of concern.

Moderate rainfall amounts expected Sunday into Monday, especially
northern California. Snow amounts through this stretch do not look
impactful and will be limited to higher elevations, especially
along the Cascades north of Highway 140.

Around Christmas Eve/Christmas, there is increasing confidence for
impactful rain in addition to potential heavy snowfall across
northern California. This will coincide with the pattern change as a
stronger upper low strengthens off the coast of California. There
will be an associated strong surface low as well. Models are in
pretty good agreement here, so we could have travel concerns around
this timeframe for heavy rain. Snow amounts continue to fluctuate,
but confidence is increasing for heavy snowfall potential across
northern California.

.AVIATION (12Z TAFs)...

A cold front continue to push through the forecast area. Rain
will transition to showers today with coverage becoming very
isolated late this afternoon/overnight. IFR and MVFR conditions
will be common through this cycle. That said, IFR/LIFR conditions
are likely for westside valleys which will impact both KRBG and
KMFR overnight as low levels remain saturated from rainfall.
