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.
UPDATE
Issued at 958 AM PDT Thu May 9 2024
Significant warming continues today, especially in the Sonoma County valleys, where earlier this morning, many stations reported temperatures 15 to 20 degrees above yesterday at the same time. The Wind Advisory has been allowed to expire for the North Bay interior mountains, with some notable wind gusts this morning including 74 mph at Pine Flat Road, 68 mph at Mount Saint Helena, and 54 mph at Mount Diablo. No changes to the forecast.
DialH
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."

(18Z TAFS)
Issued at 1038 AM PDT Thu May 9 2024
VFR thanks to offshore flow. Winds are still breezy to gusty at times, but less than yesterday. LLWS is less with stronger sfc winds and decreasing winds aloft - better mixing. Hi-res models show a southerly surge developing tonight with S winds already developing along the Central Coast. Low cig impacts tonight look to be mainly confined to MRY Bay region.
Vicinity of SFO...VFR through the period. Breezy to gusty NE flow persisting through this afternoon before switching onshore late.
Low clouds associated with S surge remain outside of Golden Gate through tonight.
SFO Bridge Approach...similar to SFO.
Monterey Bay Terminals...VFR through early tonight. Included some cigs for KSNS early Friday due to low cigs sneaking up the Central Coast. Ensemble guidance shows a 60-70% chc for low cigs at KSNS.
KMRY on the other hand are much lower at 15-20% and will only do SCT cigs.
