New AVIATION
SYNOPSIS
Issued at 304 AM PDT Tue Apr 23 2024
Cooler, unsettled conditions return today and continue throughout late week with coastal drizzle possible this morning and again tonight into Wednesday morning. Then, light rain possible for Thursday night and into Friday.
UPDATE
Issued at 904 AM PDT Tue Apr 23 2024
A healthy marine layer continues to offer almost CWA-wide stratus that will struggle to erode through the morning. An offshore eddy looks to continue to push stratus on land, preventing widespread clearing until the afternoon. This delay in clearing will result in slightly cooler highs for the areas just a bit inland from the coast, while the more interior areas and the immediate coast's temperatures will stay on track from the overnight forecast.
SHORT TERM
(Today and tonight)
Issued at 304 AM PDT Tue Apr 23 2024
Coastal drizzle is being observed across the Central Coast early this morning and will be likely in other coastal/favored upslope spots across the region through midmorning. Temperatures will warm into the upper 50s to lower 60s near the coast and up to the lower 70s in the warmest interior spots. Areas where cloud cover persists will struggle to warm out of the lower 60s.
Tonight, expect more drizzle in coastal/favored upslope spots across the region as an upper level low approaches southern California.
Overnight temperatures will range from the mid 40s to low 50s.
Increased cloud cover will spread inland as well, similar to this morning.
LONG TERM
(Wednesday through Monday)
Issued at 304 AM PDT Tue Apr 23 2024
Cooler, unsettled conditions will continue Wednesday through Friday as the aforementioned upper level disturbance moves inland.
Afternoon maximum temperatures will stay in the upper 50s to low 60s near the coast with 60s inland. Overnight minimum temperatures will cool into the mid 40s to low 50s with a few spots in the mountainous terrain dropping into the low 40s.
Light rain will be possible late Thursday evening into the first half of the day on Friday, yet rainfall amounts are expected to remain light. Northwest winds are also forecast to increase with gust near the coast and in the higher terrain approaching 25-45 mph both Thursday and Friday. As a shortwave ridge builds in wake of the exiting trough, temperatures will warm slightly to near seasonal averages by the upcoming weekend.
AVIATION
(18Z TAFS)
Issued at 1034 AM PDT Tue Apr 23 2024
The weak low pressure system continues to influence a stable, low marine layer. Satellite shows stratus socked in over all terminals causing mostly MVFR conditions that will likely clear later than usual time. Models hint at 19-20Z but higher confidence that most terminals will become VFR near 20-21Z. Stratus is expected to return later tonight causing another round of MVFR conditions for majority of the terminals. Winds will be predominately moderate to breezy out of the SW in the afternoon, then diminishing overnight.
Vicinity of SFO...MVFR stratus continues but is expected to slowly improve to VFR near 20-21Z but borderline MVFR ceilings will linger through most of the day. Gusty winds will help ceilings lift. S/SW winds will remain breezy through most of the day, then diminishing overnight.
SFO Bridge Approach...Similar to SFO.
Monterey Bay Terminals...MVFR with ceilings lifting to VFR near 20- 21Z. Timing is a bit uncertain, as the surface heating start to play a role in clearing some of the stratus out over the terminals. S/SW moderate breeze is expected to become breezy and gusty in the afternoon before returning to light to moderate overnight. MVFR conditions return tonight.
