Area Forecast Discussion National Weather Service Sacramento CA 345 AM PST Mon Jan 18 2021

SYNOPSIS. Strong gusty north to east winds will continue early this week as a weather system strengthens to the south of the region. The strongest winds are expected tonight and Tuesday. Less windy conditions expected by mid-week, then precipitation chances return for the end of the week.

DISCUSSION. Satellite imagery shows a band of high clouds moving over NorCal ahead of the initial system dropping south off the coast. North and east surface pressure gradients have continued to tighten overnight (MFR-SAC around 15-16 mbs and RNO-SAC around 9-10 mbs). We're already seeing gusts of 25-35 mph across the northern Sacramento Valley, gusts of 35-50 mph along the western edge of the Sacramento Valley, and gusts of 40-50 mph across the northern Sierra (locally above 60 mph near the mouth of the Feather River Canyon).

Temperatures remain very mild across windier portions of the area. Current readings are mostly in the 60s across the northern half of the Sacramento Valley, while temperatures are in the 40s to the south where winds are lighter. Some light valley fog will be possible to the south and east of Sacramento early this morning.

Breezy north winds will continue to spread south through the Central Valley today. Winds may subside slightly over the foothills and northern Sierra this afternoon and early evening as surface pressure gradients relax a bit.

Stronger winds are forecast to develop tonight and Tuesday as the second portion of the system drops south from the Great Basin across central California and deepens the developing closed low to the southwest of SoCal. Increasing upper level support, stronger subsidence, and strengthening cold-advection will all work drive strong winds. Widespread gusts over 60 mph will be possible across the high Sierra, while gusts of 45-55 mph will be common over the western half of the Central Valley and adjacent foothills. Gusts over the northern Sierra foothills will be more localized to ridgetops and near canyons.

For the valley, the strongest winds will likely be along the western edge of the Sacramento Valley south into the western Delta. The NAEFS anomaly table still pointing toward a potentially stronger wind event for areas to the southwest of Sacramento centered on 18Z Tuesday (return interval between 10 to 30 years). Power outages and tree damage are certainly not out of the question.

By Tuesday evening, winds will start to decrease, especially across the Valley. Gusty winds are expected to linger over the Sierra Tuesday night, weakening significantly by Wednesday morning.

Over the course the first half of the week, temperatures will gradually cool with highs returning the low/mid 60s in the Valley by Wednesday.

EXTENDED DISCUSSION (Friday THROUGH Monday). Ensembles indicate a closed upper low dropping southward along the West Coast and into NorCal Friday and Saturday. This system will bring some precipitation to the region, mainly over the northern and eastern foothills and mountains. Most precipitation is forecast to be south of I-80 over the Sierra by late Saturday morning. A few inches of snow are possible at pass levels, leading to slick roads and mountain travel delays. Dry conditions return late Saturday into Sunday as the upper low exits the region. Then, colder and wetter conditions are forecast early next week as ensembles depict a stronger/colder system that could potentially bring widespread precipitation.

AVIATION. VFR conditions next 24 hours with the exception being some MVFR visbys possible from KSMF southward through about 16Z-18Z today. North wind gusts up to 30-40 kts in the Central Valley and Delta, locally higher. Areas of northeast to east wind gusts stronger than 50 kts over the Sierra.

STO WATCHES/WARNINGS/ADVISORIES. High Wind Warning until 7 PM PST Tuesday for Northeast Foothills/Sacramento Valley-Shasta Lake Area / Northern Shasta County-West Slope Northern Sierra Nevada-Western Plumas County/Lassen Park.

Wind Advisory until 7 PM PST Tuesday for Carquinez Strait and Delta-Central Sacramento Valley-Motherlode-Mountains Southwestern Shasta County to Western Colusa County-Northern Sacramento Valley-Northern San Joaquin Valley-Southern Sacramento Valley.
