Area Forecast Discussion National Weather Service Sacramento CA 210 PM PDT Tue Mar 31 2020

Synopsis. Dry and mild weather expected this week. Breezy north winds expected tomorrow and Thursday. A storm moves in over the weekend into early next week bringing chances for rain, mountain snow, and gusty winds.

Discussion. Light scattered showers are noted across the northern mountains early this afternoon, with these showers expected to continue this evening spreading over portions of the Southern Cascades and Sierra north of I-80. Valley highs are expected to reach into the upper 60s and low 70s this afternoon with cloud cover continuing to decrease in this area.

Showers are expected to end by late tonight with dry weather continuing through Friday. Some breezy north winds are expected both tomorrow and Wednesday as a system passes to the north and east, increasing pressure gradients across NorCal. Gusts from 25-35 mph will be possible each day in the Valley.

A shortwave progresses towards the west coast Friday night, with precipitation chances beginning early Saturday morning for the northern portion of the area. Seasonal, or slightly below average temperatures are expected through the period.

EXTENDED DISCUSSION (Saturday THROUGH Tuesday).

After looking at the 5H Cluster analysis for the weekend, confidence is high that a long wave trof will dominate the wx pattern over Norcal through much of the forecast period. Although there are differences in timing and in the details a cooler and wetter scenario is favored. A pair of Pacific storms will move through interior NorCal, the first on Sat, followed by a colder/stronger low Sunday. The deterministic ECM is slower than its counterpart on Sat, then faster with the second system on Sun as the GFS slows down due to the formation of a deep closed low off the CA coast.

Widespread precipitation is expected over Norcal this weekend with Sun's system bringing periods of moderate to heavy snow to the Sierra/Wrn Plumas Co during the day and into the evening. Residual showers are expected on Mon as the trof (ECM), closed low (GFS) pass east/south of the CWA by the end of the day. Dry NWly flow aloft is forecast on Tue with a chance of some upslope showers over the Sierra in the afternoon.

A chilly/cold period is in store for Norcal with max temps some 10-15 degrees below normal on Sun, moderating to about a handful of degrees below normal on Tue. JHM

AVIATION.

VFR conditions in the Vly with local MVFR conditions from 12z-18z Wed. Over mtns, widespread MVFR and local IFR conditions with scattered showers mainly N of I-80. Freezing level 6 kft over Nrn mtns sloping to 7-8 kft over Central Sierra. Over mtns, local S-W G50+ kts, and after 18z in Sac Vly Local NW G25 kts.

STO WATCHES/WARNINGS/ADVISORIES. None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
