SYNOPSIS
Issued at 1237 PM PDT Fri May 3 2024

Cold front on track to bring widespread rain, cooler temperatures, and gusty winds this weekend. Dry weather returns Sunday with a gradual warming trend through next week.

SHORT TERM
(This evening through Saturday)
Issued at 1237 PM PDT Fri May 3 2024

Mostly clear skies over the region today ahead of the next cold front. Ample cloud cover associated with the front now moving into the northern portions of the state will continue to move southward through tonight. Areas of light rainfall are expected to begin early Saturday morning along favored west-facing upslope areas in the coastal ranges as moist low-level westerly flow increases ahead of the front. Much of the surface front should be through the Bay Area by mid-morning, and late morning for areas further south along the Central Coast. Aided by a robust 150 kt NW-SE oriented jet on the back side of the low, this will be a rather quick-moving front with little-to-no chance of stalling. However, this jet and continued support of an enhanced northwesterly Eastern Pacific jet along the West Coast will support gusty northwest winds to 25-35 mph along coastal areas and NW-SE oriented valleys through the weekend. Rainfall amounts Saturday will be in the ball park of 0.4-0.75" for most locations, with a few seeing upwards of 1-1.25" in the coastal ranges of the North Bay and the Santa Cruz Mtns.

Behind the cold front Saturday afternoon and evening, there is a slight chance for isolated thunderstorms across the area.
Scattered showers will persist into Saturday evening, but conditions appear favorable for a few locally strong updrafts that would support a rumble of thunder or two, as well as small hail.
Deep convection would not be supported, given limited cooling aloft, promoting a more stable environment aloft. Thus, any storms that do develop would be relatively short-lived. Really nothing out of the ordinary for us during these typical cold core systems, just more resemblant of a system we'd see in January rather than May.

LONG TERM
(Sunday through next Thursday)
Issued at 1237 PM PDT Fri May 3 2024

Sunday looks to be on the drier side with the low departing.
Temperatures the next few days will be on the cool side with afternoon high temps dropping by as much as 18 degrees for inland locations. Low temps Sunday morning will be in the 40s for most, with a few pockets of upper 30s for inland and high elevation areas. Otherwise, a warm up is on tap for the rest of next week as the pattern becomes more ridge-dominant. By Wednesday, expect afternoon highs in the 70s to near 80, and the mid-to-upper 60s along the coast.

AVIATION
(18Z TAFS)
Issued at 1126 AM PDT Fri May 3 2024

VFR lasts until the early to mid evening for most terminals before IFR/LIFR level clouds move inland. Winds stay W/NW and remain gusty through the evening. As stratus approaches in the evening, winds become light to moderate, and slowly turn to become more S/SW ahead of the approaching low pressure system. By the mid morning hours of Saturday, most terminals will see winds increase once more to become breezy and gusty out of the SW, and rain begins, lowering visibilities at terminals. Cloud decks are expected to improve to become IFR/MVFR as the rain approaches.
Rain continues into Saturday afternoon before dissipating, with winds turning to become N/NW and breezy.

Vicinity of SFO...VFR conditions last through the evening, with strong wings gusting to around 35 knots expected. Stratus makes moves inland in the late evening, bringing IFR conditions as winds reduce. Winds reduce further into the night and turn southwesterly. These winds become gusty as the rain arrives early Saturday morning with MVFR CIGs and slight reductions in visibilty.Winds turn to become W/NW in the later morning, but rain lasts through the afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR/LIFR CIGs push inland in the early evening. IFR/LIFR CIGs last through the majority of the overnight hours with lighter winds. As the rain band arrives, expect CIGs lift to become IFR/MVFR late Saturday morning. Gusty westerly winds build along the rain band.
