Area Forecast Discussion National Weather Service Sacramento CA 257 PM PST Wed Dec 11 2019

SYNOPSIS. Light rain at times through Thursday, heaviest in the mountains. Widespread precipitation also expected later in the week and into the weekend. Drier weather Sunday and early next week.

DISCUSSION. Precip should increase over our forecast area tonight into Thu as a strong 150kt Pac jet south of the GOA (Gulf of AK) low reaches the coast and focuses a +3 PW anomaly into our CWA. The U.S. West Coast AR Tool shows that a "weak" AR (TPW/moisture plume) along 130W will make "landfall" during this time tonight and into Thu. Rising 5H heights will steer the storm track and main dynamics a little farther N and into the Pac NW. But the strong WAA tonite and Thu (over 5 deg C/12 hr in the 850-700 mbs layer) will interact with the moisture plume resulting in steady precip over Norcal, mainly over the Nrn mtns and areas N of I-80. One to two inches of precip is forecast over Shasta Co/Wrn Plumas Co during this time, with amounts tapering off rapidly Swd to the I-80 corridor. South of I-80/US-50, only a few hundredths are expected as the storm track shifts Nwd. Snow levels are relatively high due to the transport of subtropical moisture from Hawaii. The snow profilers indicate a snow level around 5500 ft at Shasta Dam, around 7500 ft at Oroville, and Colfax, and could rise some 500 to 1500 ft overnite due to the WAA.

The wet wx should continue on Fri as 5H heights begin to fall slowly as the GOA trof emerges from its source region. This will keep the TPW plume over our CWA through the day. Model freezing/snow level forecasts came in a little colder than previous runs and we began to lower them a little from earlier forecasts. Looks as if the snow level will drop below the passes along the I-80/US-50 corridor by Fri morning. There is likely to be enough QPF Fri and FRi nite (and maybe into Sat) to warrant a snow advisory as the snow levels drop below the Sierra passes. With the bulk of the precip falling over the Sierra, our total QPF thru 12z Sun is now falling in line within the body of the ECMWF ensembles box/whisker plots for BLU, as an example.

The precip should turn more showery on Sat as the colder/unstable air drops into Norcal as the upper low and trof move across the NErn Pac to the Pac NW/Nrn CA coast before winding down on Sun. Snow levels should drop to 3500 ft Nrn mtns to 4000 ft in the Sierra late Sat, but by then the precip will be diminishing. JHM

EXTENDED DISCUSSION (Sunday THROUGH Wednesday).

The weather system bringing multiple days of rain and snow to northern California will be moving out of the area by early Sunday morning. As troughing moves towards the southwest US, upper level ridging begins to build over the west coast. Dry weather and mostly clear skies are anticipated by mid-afternoon Sunday, with these conditions continuing through at least Monday. Tuesday onward, models have varying solutions for when another trough will impact the area bringing additional chances for precipitation. Went with ensemble guidance for this forecast bringing back wet weather to the area Tuesday, although confidence is still low at this time with the onset of any rain. Temperatures remain fairly steady Sunday into next week with Valley highs topping out in the mid-50s. Mountain locations will mainly see high temperatures in the 30s.

AVIATION.

Widespread MVFR/IFR conditions seen through around 20Z. Brief improvement may be seen before another storm brings -RA after 02Z. MVFR/IFR ceilings return by early morning to all sites. VCSH possible around 12Z at Sac terminals. Winds generally less than 12kts.

STO WATCHES/WARNINGS/ADVISORIES. None.
