.UPDATE...
Issued at 853 AM PDT Tue Mar 10 2026

Low level stratus encompasses most interior areas of the South Bay 
and Central Coast this morning. These clouds will dissipate and give 
way to mostly sunny sky conditions this afternoon with temperatures 
forecast to be in the 60s to lower 70s. Otherwise, the ongoing 
forecast remains on track. We will continued to look into how 
warm/hot this weekend and into early next week will be!

.SHORT TERM...
Issued at 243 AM PDT Tue Mar 10 2026
(Today and tonight)

Today will be the coolest day through the extended forecast. The 
EPAC ridge that will dominate our pattern for the next week and 
beyond will continue to build today. However, a broad trough axis 
extending from the Great Basin into NorCal interacting with the 
building ridge will produce gradient forcing for the gusty northwest 
winds along the coast, especially for the North Bay and Bay Area 
coastlines, along with a tight thermal H85 gradient across 
NorCal. Temperatures along the coast will be slightly below normal
with gusty northwest winds this afternoon. High temperatures 
inland will run about 5 degrees above normal for most locations 
with occasionally breezy northwest winds. While surface winds ease
this evening, H85 flow will begin to increase and become offshore
once again. With light and variable surface winds tonight into 
Wednesday morning, along with the developing offshore boundary 
level flow producing mostly clear skies, more efficient 
radiational cooling will result in lows in the 40s and even upper 
30s for higher elevations.

.LONG TERM...
Issued at 243 AM PDT Tue Mar 10 2026
(Wednesday through Monday)

By Wednesday afternoon, the warming trend through the remainder of 
the extended forecast will be in full swing. Highs will be in the 
70s for a majority of our area, some 60s along the coast and low 80s 
in the southern Salinas Valley. We'll see more widespread 80s for 
the remainder of the work week into the weekend with 90s in the 
southern Salinas Valley by Sunday, expanding in area by the 
beginning of next week. We'll see widespread Minor HeatRisk set in 
Wednesday and persist through Saturday with increasing areas of 
Moderate HeatRisk Sunday and Monday. The warm temperatures will 
persist through much of next week. Deterministic guidance is 
beginning to pick up on some offshore troughing as the impressive 
dome of high pressure meanders east well beyond the current forecast 
range.

Near gale to gale force winds affect the waters through the day 
and into the night. As a result, very rough seas will build in the
outer waters. Winds reduce into early Wednesday, but rough seas 
and fresh to strong northerly breezes will keep hazardous 
conditions around through the weekend.
