New SYNOPSIS, SHORT TERM, LONG TERM
SYNOPSIS
Issued at 143 PM PDT Mon May 29 2023
Temperatures continue to look to be on the below normal side over the next few days as continued troughing dampens any chance at warming up until the weekend. Stratus will continue to be present at coastal areas through the nights and early morning, before clearing later in the day. A slight warm-up expected late in the week.
SHORT TERM
(This evening through Wednesday) Issued at 143 PM PDT Mon May 29 2023
A glance at satellite imagery this afternoon shows stratus lingering in the North Bay, near Santa Rosa and Petaluma, and Monterey Bay region. Elsewhere, the stratus has mixed out, lending to mostly clear skies. The cutoff low that has pestered the region the last few days continues to hang around, but has made its way far enough south to be sitting off the Monterey/ San Louis Obispo county coast. As it does so, it will continue to keep temperatures cool and below normal, similar to what we've seen the past few days. It is not until mid to later week that it is expected to exit off to the southeast.
That being said, continue to expect high temperatures near the coast to remain in the upper 50s to mid 60s, with inland regions reaching closer to low 70s. Low temperatures range from the upper 40s to low 50s. Near the coast, the stratus is expected to continue in the same pattern we have seen: robust and extending inland overnight, then generally clearing and mixing out in the late afternoon. Drizzle remains a possibility closest to the Big Sur coast.
LONG TERM
(Thursday through Sunday) Issued at 143 PM PDT Mon May 29 2023
Towards the end of the week, in the Thursday and Friday time range, models seem to be in better agreement as to temperatures gradually beginning to warm up as slight ridging begins to build in. Ridging looks to be most amplified Saturday, lending to the warmest temperatures of the week, bringing them closer to averages for this time of year. However, another low looks to move in beyond this, helping to break down the ridge and reduce temperatures again to below-normal for the first portion of June.
Current CPC outlooks concur, placing much of the region under below-normal temperatures through at least the next fourteen days.
AVIATION
(18Z TAFS)
Issued at 1030 AM PDT Mon May 29 2023
Current satellite shows closed low continuing to rotate off the central CA coast bringing in a stout feed of moisture into the region. DZ and SHRA activity expected to be much less likely today as opposed to yesterday. As the low moves to the southwest of the area, should see more widespread clearing of the stratus today.
In terms of cig height, marine layer has been holding steady at about 2500 feet and a moist layer down to about 1200 feet per this morning's sounding from KOAK. Breezy onshore flow this afternoon and a return of stratus this evening with higher-than-normal uncertainty across southern portions of the region due to interaction from the low.
Vicinity of SFO...Expect mostly VFR through the day today with some interaction from mid-level clouds associated with moisture wrapping around the top of the low. Breezy onshore this afternoon. Stratus return with MVFR cigs tonight by midnight through Tuesday mid- morning.
SFO Bridge Approach...Similar to SFO.
Monterey Bay...Slow to clear this morning with a robust marine layer still intact up to 2500 feet. Breezy onshore flow this afternoon with clearing to VFR and some lingering mid-to-high clouds.
Uncertain regarding timing the stratus return this evening due to interaction with the low that will be moving into south-central CA.
MARINE
(Today through Saturday)
Issued at 1030 AM PDT Mon May 29 2023
A 9 to 10 second northwest swell with a 18 to 20 second southerly swell prevails. Winds are mainly light to breezy, as the stronger winds are being measured farther out to sea. Winds remain mostly southerly today as the low meanders about off the coast.
Northwesterly winds will begin across the seas starting by Tuesday afternoon as the low moves ashore. Increasing winds through midweek create steeper wind driven waves.
MTR WATCHES/WARNINGS/ADVISORIES
CA...None.
