SYNOPSIS
Issued at 245 AM PDT Thu May 9 2024

A warming trend that kicked off yesterday will continue today and persist into tomorrow across the interior. Conditions begin to cool near the coast on Saturday with interior areas remaining 5-15 degrees above average into early next week.

SHORT TERM
(Today and tonight)
Issued at 245 AM PDT Thu May 9 2024

Clear sky conditions prevail across the region this morning as off shore winds continue aloft. This will result in a warming trend today with temperatures reaching the mid-to-upper 80's across the interior while 70's will be common near the coast (closer to the lower 80's in places such as Santa Cruz and Downtown San Fransico).
This will bring Minor HeatRisk to the coast today with Moderate HeatRisk across the North Bay, East Bay, and South Bay both today and Friday.

A Wind Advisory remains in effect for the North Bay Interior Mountains with gusts expected to reach 45 mph and may exceed 55 mph in the Mayacamas Mountains through 8 AM this morning. Gusts in the East Bay Hills are not expected to be widespread enough to warrant an advisory, but Mount Diablo is expected to see gusts of 40-50 mph this morning.

Overnight lows will be warmest in the North Bay and interior part of the East Bay given the weakening offshore flow with temperatures only expected to cool into the mid-to-upper 50's. Elsewhere, low-to- mid 50's are expected overnight. The HRRR is showing signs of a southerly surge arriving by late afternoon and into the overnight hours. If were to occur, expect much cooler temperatures near the coast on Friday.

LONG TERM
(Friday through Wednesday)
Issued at 245 AM PDT Thu May 9 2024

Friday is expected to be the warmest day of the week, especially for inland locations. Again, a southerly surge may cool conditions at the coast, but the interior will still warm into the mid-to-upper 80's to lower 90's.

With the significant warm up expected for the rest of the week, here's a reminder of some heat safety tips:

* Stay hydrated and drink plenty of fluids.
* Wear lightweight, light-colored clothing.
* Reduce time spent outdoors or stay in the shade.
* Never leave people or pets unattended in vehicles.
* Use sunscreen if going to the coast or the pool.

As onshore flow increases, temperatures will cool regionwide.
However, interior areas will remain 5-15 degrees above average into early next week.

From the previous forecaster: "Ensemble models and clusters are showing that another ridge approaches the West Coast next week, which could help maintain temperatures above the seasonal averages.
CPC products are showing temperatures above seasonal averages continuing into the third week of May."

AVIATION
(12Z TAFS)
Issued at 349 AM PDT Thu May 9 2024

VFR through the TAF period. At this hour, winds are predominantly light and N/NE. Northerly winds will increase throughout the morning and early afternoon today to become breezy around 10-15 knots for most terminals. By the late afternoon, winds are expected to turn to take on a more onshore flow pattern but begin to ease. Into the overnight of Thursday into Friday, winds become light, and coastal stratus slowly begins to push northwards along the Monterey coastline. Towards the end of the TAF period, stratus will begin to filter into the southernmost terminals.

Vicinity of SFO...VFR prevailing. Light NE winds prevail through the morning. In the afternoon, winds strengthen to become breezy and turn to become onshore. Light and variable winds return in the later evening.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR prevailing, though FEW-SCT low clouds are likely to develop over the terminals towards the very end of the TAF period. At this time, confidence in CIG development is low, with chances currently only standing at around 20-30% at best. However, with ongoing ridging, any clouds that do form over the terminal are likely to be around 1000' or less, as the marine layer is compressed. Aside from this, breezy onshore winds expected in the afternoon today once again. Winds ease into the nighttime to become light.

MARINE
(Today through Tuesday)
Issued at 245 AM PDT Thu May 9 2024

Moderate northerly winds continue through the morning, but slowly ease to become gentle into the daytime. The one exception is the Big Sur and Monterey Bay region where winds turn to become more southerly and fresh in the afternoon today. Otherwise, gentle breezes out of the north and northwest continue through the weekend first portion of the weekend. Dry weather continues through the forecast period as high pressure dominates.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Wind Advisory until 8 AM PDT this morning for CAZ504.

PZ...Small Craft Advisory from 9 AM this morning to 3 PM PDT this afternoon for Mry Bay-Pigeon Pt to Pt Pinos 0-10 nm-Pt Pinos to Pt Piedras Blancas 0-10 nm.
