Synopsis for the central california coast and bays including the Monterey bay..Greater farallones...and cordell bank national marine sanctuaries... Low pressure west of big sur is producing Thunderstorms over the offshore waters. The threat for showers and Thunderstorms will increase tonight through early Saturday. As the low moves towards the coast some southerly gale force winds will occur near pt pinos and locally into Monterey bay. Gusty west winds from the golden gate out into the west delta will create rough seas inside the bay through tonight. A long period south swell is also passing through the waters and may create dangerous surf conditions. The low will shift north of the area by Saturday night and Sunday with a return of nw wind and seas.

Area Forecast Discussion National Weather Service Sacramento CA 306 PM PDT Fri May 29 2020

Synopsis. A low pressure system will move through Norcal tonight and Saturday bringing cooler temperatures and numerous showers and thunderstorms. There is the potential for heavy rain over western Tehama and Shasta Counties. Some mountain showers and thunderstorms are possible early next week.

DISCUSSION. Yesterday's double digit cooling in the Carquinez Strait/Delta region has made its way well inland with the exception of the Nrn Sac Vly. That will change this evening as the up valley flow becomes stronger later this afternoon and evening. The up valley RDD-SAC gradient was approaching 3 mbs this afternoon, and by 4 mbs, we usually see a Sly wind reported at RBL/RDD. As mentioned yesterday, the Delta Breeze was blowing at 22-29 kts since last night and this momentum will continue as the closed upper-level to our SW approaches. With the deepening marine layer (Ft Ord up to 2000+ ft this morning) marine stratus should make its intrusion into the Srn Sac Vly. This will be masked by the high level cloudiness already progressively invading the Norcal sky ahead of the offshore low.

Now that the heat concern has been alleviated, we focus on the thunderstorm and potential for locally heavy rain threat. The closed upper level low vcnty 32N/125W will tend to phase a couple of PWAT plumes as it moves towards the MTR/SFO Bay areas early Sat morning, and then over Norcal on Sat. The NAEFS anomaly table shows about a +3 PW anomaly over Norcal on Sat, and about a 5 year return interval, highlighting the potential for some heavier rainfall. The morning raobs in the area were already reporting PWs about 150% of normal.

Although the NAM 3km REF prog keeps our area quiet this evening, it explodes an area of SE to NW oriented convection from just N of SAC around 2 am and then lifts it Nwd roughly from BLU-OVE-N of Alder Springs early Sat morning. This is right in the area of strong PVA and upper level diffluence in the NE quadrant of the approaching closed low. Elevated convection is expected per the elevated instability progs. Forecast soundings look quite wet during this time with PWs above 1.0" at BAB, CIC, RBL, RDD. Moist SEly flow around the closed low should favor the east side of the Trinity Alps/Coastal Range (our western Tehama/Shasta Counties) for some heavier rainfall. There is little CAPE in these wet soundings overnite and early Sat, so hail is not the main issue, but heavy rain. There is a little more elevated CAPE forecast Sat afternoon suggesting small hail, but continued potential for heavy downpours.

Earlier indications suggest some areas in wrn Tehama and Shasta Counties could receive 0.60-0.80" in the 6 hr period early Sat morning, and about 1.50" for the Sat/Sat nite time frame. The NBM has been hitting wrn Tehama County a little harder with QPF than Shasta County which would keep the heaviest rainfall to the south of the Carr, Hirz, Delta burn scars. This is in-line with the HREF probability of one hour rainfall greater than a half inch mainly across Tehama County early Sat. However, the Shasta/Tehama County area generally remains in the "overlap" of the WPC excessive rainfall outlooks for early Sat, then later Sat, as convection redevelops in that general vicinity during the afternoon/early evening. Thus, we have decided to issue a FFW (Flash Flood Watch) for that "overlap" area mainly W of I-5 and below 3 kft in our CWA in Shasta/Tehama Counties.

The shower and thunderstorm threat will diminish by late Saturday afternoon and evening, with a residual chance of showers and storms into Sun over the Nrn mtns and Sierra with the approach of a secondary Pac trof. The trough will bring more widespread mountain showers and afternoon thunderstorms on Monday.

After the big heat wave, Norcal will experience a big cooling trend on Sat, so don't put away your jacket or sweater just yet. Max temps will be about 7 to 20 degrees below normal on Sat, moderating to 3 to 7 degrees below normal in the valley, then a few degrees below normal on Mon, while most of the mountain temps will continue to run 10 to 15 degrees below normal Sun/Mon. JHM

EXTENDED DISCUSSION (Tuesday THROUGH Friday).

Ensembles continue to show a deep cutoff low stalling just off the southern California coast next week. Depending on how far north this low sets up, embedded shortwaves along the northern portion of the low could produce mountain shower and thunderstorm chances each afternoon next week. Other than that, dry and warm conditions are expected. Temperatures will warm back up to around 5 to 10 degrees above normal Tuesday through Thursday. Temperatures will stay fairly steady with Valley highs in the low 90s and mountain highs in the 60s to 70s. Ensembles still indicating a trough approaching from the Gulf of Alaska Friday which could cool temperatures back down to normal and maybe bring a chance of precipitation to the northern mountains. HEC

AVIATION.

VFR conditions with BKN-OVC AC/CS overspreading TAF sites tonite. Chance of short lines/areas/clusters of elevated thunderstorms developing after midnight in the Srn SAC Vly, lifting NWD and becoming more numerous by early Sat morning. Scattered thunderstorms redeveloping Sat afternoon. Expect MVFR/IFR conditions in showers/thunderstorms through 03z Sun. Delta Breeze 22-29 kts with gusts around 40 kts late tonight and Fri through the Carquinez Strait and into the Sac Delta will likely advect marine stratus inland early Sat morning with MVFR cigs. Widespread IFR/LIFR conditions over mtns on Sat obscuring hyr trrn.

STO WATCHES/WARNINGS/ADVISORIES. Flash Flood Watch from Saturday morning through Saturday evening for western portions of Shasta and Tehama Counties below 3000 feet.
