...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 1205 PM PDT Sat Jun 7 2025

Quiet pattern remains through the extended period with
temperatures right around seasonal averages nearly across the
board. Slight cooling trend by the end of next week.

&&

.SHORT TERM...
(This evening through Sunday)
Issued at 1205 PM PDT Sat Jun 7 2025

Very subdued pattern ongoing currently with seasonal temps and
good onshore flow. Current RAP analysis showing a broad upper
level ridge building over the PNW while a weak closed low remains
separated from the jet stream flow and meandering nearly
stationary off the CA coast. The marine layer is a bit shallower
than 24 hours ago but really not having much sensible impact under
the ridge thanks to the reinforced onshore flow from the closed
low. Inland locations will heat up a few degrees Sunday, but
really not too much impactful change, especially for areas closer
to the coast.

.LONG TERM...
(Sunday night through next Friday)
Issued at 1205 PM PDT Sat Jun 7 2025

This pattern largely continues into next week before the ridge
starts to break down and a deeper trough pattern starts to dig
into the West Coast. Once again not much notable change noted with
this subtle pattern change. Temperatures gradually cool a few
degrees through the middle of the week ending up a few degrees
below seasonal normals. The good news is that robust onshore flow
looks to persist through the forecast period which will at least
help to stunt the drying of fire fuels at least through the next
week. Fuels across much of the region remain around or above
seasonal average moisture. Worth keeping in mind that this
includes large fuels as well, so it`s worth noting that fine fuels
such as grasses are indeed very dry and susceptible to easy fire
starts.
