Come the evening of Saturday, northwesterly winds increase to become strong and gusty. SWell builds into Sunday out of the northwest as gusty conditions continue but look to diminish towards the middle part of the next week.

New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 215 AM PDT Fri Apr 19 2024

Cooler conditions are expected today and tomorrow with light drizzle possible each morning. Temperatures rebound late weekend and early next week. A return to unsettled conditions arrives Tuesday and persist throughout late next week.

SHORT TERM
(Today and tonight)
Issued at 215 AM PDT Fri Apr 19 2024

A well defined marine layer is in place this morning (around 1800- 2000 ft per Fort Ord Profiler) and will support patchy drizzle in the upslope regions this morning. Otherwise, this afternoon sunny conditions will return to inland areas with temperatures expected to warm into the low to mid 70s. Meanwhile, the coast remains in the upper 50s to mid 60s under mostly cloudy conditions.

Tonight, expecting clouds to make a return back inland and become more widespread with low temperatures in the upper 40s to lower 50s.
Again, patchy drizzle will once again be possible. Saturday will feature slightly warmer temperatures inland, but only by a few degrees. Wind will also be on the increase with breezy northwest winds near the coast, in the coastal hills, and into the region's valleys. Looking for gusts of 25-35 mph in these areas by Saturday afternoon.

LONG TERM
(Saturday through Thursday)
Issued at 215 AM PDT Fri Apr 19 2024

By Sunday and Monday, ridging dominates the pattern once again with interior areas warming to near 80 degrees with 60s and 70s as one gets closer to the coast. By Tuesday, a change to more unsettled conditions return as an upper level low approaches the region. This pattern will persist throughout late week and points to possible wet weather during the latter half of the week. However, there is no major concerns for flooding and may end up being widespread light drizzle if not light rain. Temperatures also turn cooler with highs in the upper 50s at the coast and mid-to-upper 60s inland from Tuesday throughout late week. Stay tuned!

AVIATION
(06Z TAFS)
Issued at 1114 PM PDT Thu Apr 18 2024

A mix of predominantly LIFR and IFR conditions through the night tonight and the late morning of Friday. North Bay and Monterey Bay terminals are likely to see LIFR conditions persisting through the overnight hours and into the late morning as a result of fog and low stratus CIGs . Sinking, drier air aloft is likely helping to lower and squash CIGs down to around 1400 feet currently per the Bodega Bay profiler, and 1800 feet per the Ft. Ord profiler. Expect these CIGs to lower progressively through the night and into the morning hours. Terminals in the SF Bay region are more likely to see MVFR conditions per model suggestions, though confidence on this is only moderate, given the low CIGs elsewhere. A drop into IFR CIGs for SF Bay terminals overnight is not out of the question. Decent onshore flow overnight will also be a factor in helping advect stratus inland, leading to robust cloud coverage through at least the late morning of Friday. In the early afternoon, as things heat up, clouds should begin to mix out bringing a return of VFR conditions and breezy to moderate onshore winds.

Vicinity of SFO...SFO in particular overnight appears to remain the odd one out, as it is likely to remain in VFR territory, with good agreement among numerous models. Despite good onshore flow overnight around 6-7 knots, given the fact that the stratus deck currently sits around 1400' and is expected to lower, stratus may not be able to rise above and advect through the San Bruno gap, keeping conditions clear and VFR locally at SFO terminal. Additionally, any stratus that fills over the bay waters will be likely kept just on the periphery of the SFO vicinity as good overnight flow out of the west helps keep any stratus over the bay away and pushed more towards the KOAK side. KOAK conversely will likely see IFR conditions last through the nighttime as good overnight onshore flow helps push stratus through the Golden Gate gap and into the SF bay. Late clearing is expected at KOAK with VFR returning in the late morning to early afternoon.

SFO Bridge Approach...IFR-LIFR conditions are likely as robust stratus coverage develops overnight over the SF bay waters thanks to good onshore flow. Clearing expected into the very late morning to early afternoon of Friday to VFR.

Monterey Bay Terminals...IFR/LIFR through much of the night as a result of very low CIGs . Stratus is expected to continue to lower through the night. Some reductions in visibility are possible as CIGs lower and the air reaches saturation near the ground, leading to mist and fog development. However, confidence on mist and fog development is not as strong as confidence in CIGs lowering. This will be something to watch closely overnight. VFR returns in the early afternoon though a FEW-SCT low clouds may linger, with winds onshore and around 10 knots. Stratus makes an early return in the evening of Friday.

MARINE
(Tonight through next Wednesday)
Issued at 1114 PM PDT Thu Apr 18 2024

Expect light to moderate winds into the weekend before breezy to gusty northerly winds arrive Saturday afternoon that will increase hazardous conditions over the waters. Wave heights will start to build heading into the late weekend before diminishing by mid- week. Another moderate period northwest swell arrives over the weekend as well as another light, longer period (18 seconds)
southerly swell.
