Area Forecast Discussion National Weather Service Sacramento CA 232 PM PDT Sun Mar 29 2020

Synopsis. Rain and snow showers will continue through this evening. Threat of showers persists in the north Monday through Tuesday afternoon, otherwise drier and milder into mid-week.

Discussion. Scattered showers continue across the region this afternoon, mainly west of I-5 and the northern Sierra. Precipitation amounts have ranged from less than 0.05" in the Valley to around 0.05" to 0.50" in the northern mountains and northern Sierra today. Profiler at Colfax shows snow levels currently at around 5000 feet. Additional snow accumulations through this evening will be light, generally less than an inch. Cloudy skies are preventing thunderstorm development this afternoon. Precipitation activity tapers off for most areas this evening as the trough shifts to the east.

A weather system tracking through the Pacific NW will bring a threat of showers to portions of interior NorCal Monday through Tuesday afternoon. Given that best dynamics will remain north of the forecast area, shower chances will be limited to the northern Sacramento Valley, and higher elevations north of I-80. QPF amounts have trended wetter with this system; currently expecting 0.35"-1" (locally up to around 2") in Shasta County and 0.10-0.50" elsewhere. Snow levels are forecast to be from 4500-6000 feet, with snow accumulations in the 1 to 3 inch range except for higher amounts over Lassen National Park. Elsewhere, cloudy skies and dry weather will prevail. Breezy south winds are possible Monday through early Tuesday; gusts up to 15-20 mph are possible.

Regarding temperatures, highs are forecast to warm up slightly each day, and will be near average by Wednesday. Forecast highs on Wednesday will be 5 to 10 degrees warmer than Monday, with Valley highs in the 60s.

EXTENDED DISCUSSION (Thursday THROUGH Sunday). Deterministic and ensemble guidance have trended toward a cooler solution in the extended instead of an amplifying ridge. High temperatures are expected to reach the mid 60s to low 70s across the Valley, while mountain locations will be in the low 40s to upper 50s. An unsettled pattern may return next weekend into early next week as disturbances drop down from the north into the region. Confidence in precipitation amounts and coverage is low this far out given that model solutions diverge significantly.

AVIATION. MVFR cigs expected thru 22Z at RBL/RDD with MVFR cigs returning after 12Z at these terminals. Elsewhere, VFR conditions are expected with winds generally under 12 knots. Breezy south winds and chance of rain at northern Sac Valley terminals after 18Z tomorrow.

STO WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
