Area Forecast Discussion National Weather Service San Francisco Bay Area 448 AM PST Tue Mar 2 2021

SYNOPSIS. Dry and mild weather conditions will prevail over the region through midweek with slight cooling likely late in the week. Rain chances increase late Friday into Saturday with the potential for unsettled conditions to persist into early next week.

DISCUSSION. as of 03:23 AM PST Tuesday . A mid/upper level low pressure system and associated trough remains well off of the West Coast early this morning. It's only impact to the region is mid/high level clouds advecting inland across California as dry weather conditions prevail at the surface. This system is forecast to remain well enough offshore to maintain dry conditions over the region before eventually dropping southward and then across southern California on Wednesday. Day-to-day fluctuations in temperatures are expected to be minimal through midweek, yet will be at or above seasonal averages. Generally speaking, look for upper 50s to lower 60s at the coast with more widespread 60s to near 70 inland. Meanwhile, overnight lows will range from the mid/upper 30s in the colder interior valleys with 40s elsewhere.

As the aforementioned system shifts inland over the Desert Southwest through midweek, a mid/upper level trough will deepen over the eastern Pacific late in the week. This system is then forecast to shift eastward toward the West Coast late in the week potentially bringing widespread precipitation to the region Friday night into Saturday. However, the deterministic and most ensemble members only indicate light precipitation for our region. Temperatures late in the week and into the upcoming weekend will also cool as a result.

Beyond the upcoming weekend, the ensembles favor unsettled weather conditions across our region heading into next week as troughing persists over the eastern Pacific and along the West Coast. However, this pattern would likely only result in light precipitation amounts for our region. Seasonably cool conditions are also likely given this pattern.

AVIATION. as of 4:48 AM PST Tuesday . For the 12Z TAFs. VFR. Low clouds continue to focus near a cool front very slowly approaching the southern and central outer coastal (and offshore) waters per recent satellite imagery and NAM output. The cool front looks mainly elevated until later today and tonight when surface cooling arrives based on the NAM and the air ahead of the front is still dry to very dry. Add in today's diurnal mixing and chances are good the low clouds will mix out prior to reaching the north Central Coast later today despite recent high resolution model forecasts showing otherwise. Best chance of coastal low clouds will be tonight and Wednesday morning as cool air advection combines with nocturnal cooling. Not confident enough to introduce bkn-ovc ceilings KMRY and KSNS for the 12z taf cycle, later shifts can reassess and add ceilings if needed. Meanwhile high clouds will continue to move in stretching out from the low offshore, the low reaches southern California Wednesday. Vicinity of KSFO . VFR, light and variable wind increasing to 10 knots westerly in the afternoon and early evening. SFO Bridge Approach . Similar to KSFO.

Monterey Bay Terminals . VFR, cool air drainage winds this morning becoming onshore 5 to 10 knots in the afternoon and early evening. Cool air advection and cool air drainage winds combining tonight and Wednesday morning tending to offset low cloud development, at least for mid to late Tuesday evening. Lower confidence cloud cover forecast late tonight and Wednesday morning.

MARINE. as of 3:53 AM PST Tuesday . A low pressure system over the eastern Pacific will reach southern California Wednesday. Building northwest swell will cause hazardous sea conditions for smaller vessels later today into the evening. A moderate period northwest swell will then turn to long period swell late in the week. A slow moving low pressure system arrives from the northwest late in the week with rain this weekend.
