New AVIATION

SYNOPSIS
Issued at 1254 PM PDT Sun Jun 15 2025

Continued quiet conditions through early week. Slight warming slated for the middle of the week with cooler temps and potential offshore wind by next weekend.

UPDATE
Issued at 844 PM PDT Sun Jun 15 2025

As the sun sets we prepare for another night of stratus developing in the marine layer. Similar to last night, we don't have a big bank of clouds along the coast, but onshore winds and the mostly clear marine layer persist. This means clouds will have to form, rather than advect in. It's difficult to predict exactly what will happen, but areas that develop clouds will see them arrive later than normal and they should clear earlier in the morning for most.

SHORT TERM
(This evening through Monday)
Issued at 1254 PM PDT Sun Jun 15 2025

Gorgeous couple of days with temps right around or slightly below seasonal averages. A transient shortwave trough will act to cool temps a couple of degrees to start the work week. Other than that, no major changes or impacts in the short term.

LONG TERM
(Monday night through next Saturday)
Issued at 1254 PM PDT Sun Jun 15 2025

Warming trend into Wednesday looks to bring temps around or a few degrees above seasonal averages as high pressure builds over Baja ridging up into the PNW. Wednesday does look to be the peak of the warming before a deeper and potentially more impactful trough moves in by the end of the week. Still evaluating specifics, but there appears to be at least a slight risk of offshore wind in the North Bay by next weekend. With grasses very dry and larger fuels not far behind, this certainly looks like a window for more elevated fire weather concerns. Stay tuned for updates.

AVIATION
(06Z TAFS)
Issued at 939 PM PDT Sun Jun 15 2025

Currently a mixed bag of IFR-VFR at the terminals with stratus along the Tomales Bay, San Francisco Peninsula Coast, and Monterey Bay.
Generally a persistence forecast with MVFR/IFR ceilings returning to coastal and bayside terminals. Moderate and gusty onshore winds are expected tomorrow afternoon and evening.

Vicinity of SFO...Currently VFR with westerly flow. Westerly winds will prevail through the TAF period with gusts up to 30 knots to be expected. There's a 60% probability for sub-VFR ceilings to impact the terminal tonight with most guidance showing low-end MVFR, but the risk for IFR is there as well. High confidence in VFR prevailing by late-morning alongside strong and gusty westerly winds.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently IFR with southwesterly flow at MRY and VFR with northwesterly flow at SNS. High confidence in SNS deteriorating to IFR tonight with VFR and westerly winds prevailing by late-morning.

MARINE
(Tonight through next Saturday)
Issued at 844 PM PDT Sun Jun 15 2025

Fresh to strong northwesterly breezes, near gale force gusts, and moderate to rough seas will prevail through Thursday. Gale force gusts are expected near the coastal jet regions of Point Reyes and Point Sur.

FIRE WEATHER
Issued at 556 PM PDT Sat Jun 14 2025

No real notable changes to the ongoing forecast fire weather wise.
Still highlighting elevated fire weather conditions across the interior Central Coast. While not in our forecast area, a decent veg fire developed and spread quickly to over 1k acres in SLO.
This could have easily happened in San Benito or Monterey counties.

Observations over the last 24 hour and predicted weather continue to show marine layer influence keeping fire weather conditions in check for lower elevations and coastal areas. However, about roughly 2k feet and farther inland conditions remain mild and dry both day and night. On top of that is onshore flow leading to breezy conditions each afternoon. Some of the winds are being enhanced by topography leading to gustier flow in the valleys, gaps, passes with 20-35 mph gusts.

Simply put, if you're recreating outdoors, be one less spark in these elevated fire weather conditions.
