SYNOPSIS
Issued at 1145 AM PDT Fri Apr 12 2024

Cooler and cloudier for today as highs fall back into average range as the next rain-maker nears. Expect winds to increase into the 15 to nearly 20 mph range with gusts of 25 to 40 mph by Saturday morning. Showers are forecast to arrive after sundown Friday with widespread showers across the Bay Area and Central Coast by mid-morning Saturday. Saturday afternoon will feature a renewed batch of showers with an increasing potential for thunderstorms. Storms may produce bouts of small hail. Showers linger through early Sunday afternoon across interior sections.
After a noteworthy cool down this weekend, a warming trend will ensue next week.

SHORT TERM
(This afternoon through Sunday Evening)
Issued at 1145 AM PDT Fri Apr 12 2024

The forecast remains on track with just a few minor alterations.
As noted above, showers are forecast to arrive after sundown Friday across the North Bay, though some light sprinkles or patchy drizzle cannot be discounted along the coastal regions, particularly down along the Big Sur.

Satellite imagery late this morning shows the first vestiges of our upper level low now impinging on portions of the North Bay in the form of high cirrus. We'll turn our attention back to this feature shortly. Pesky stratus farther south across the SF Peninsula and Central Coast continues to gradually erode, though some areas across the Santa Cruz Coast and Monterey Bay region will stay completely socked in until later this afternoon. For regions that get to experience the sunshine, enjoy it, as this weekend will turn rather unpleasant for outdoor activities.

The latest short term and even coarser guidance for our next round of rain/storms has come into really solid agreement regarding the timing of precipitation. Overall, rainfall amounts remain consistent with earlier forecasts. Even looking at the spread between the lower QPF rain amounts and worst case scenario yields only a 0.75 inch difference for most areas (a little higher for the mountainous terrain). All in all, most of the inland areas can anticipate up to 0.75 inches of rain, with coastal areas averaging between 0.75-1.25 inches of rain. The big winners, rain amount wise, will be the Santa Cruz Mountains, Santa Lucia Range, and the Big Sur Coastline where 1.25-2 inches of rain are forecast. The chances of exceeding 2.5 inches over a 72 hour time period for the higher terrain east of California HWY 1 are around 30%. Regardless of exact amounts, pockets of moderate to briefly heavy rainfall will result in ponding and some rises on area creeks, rivers, and streams---though most of this rainfall should be beneficial and not result in flooding. However, the potential for slides will increase, especially across the Santa Cruz Foothills/Mountains and across the Big Sur coastline.

Non-convective winds will increase as the low level height/surface pressure gradients tighten. Southerly winds will increase later today and into Saturday and the chances of seeing wind gusts of over 25 mph ranges from near 50-60% across the North Bay to over 75% for the other areas. The potential to exceed 35 mph wind gust really becomes confined to the higher terrain (Santa Cruz Mountains, East Bay Hills, Diablo and Santa Lucia Ranges) and along the coast (Monterey Bay and Big Sur). The chances to exceed 35 mph in these areas ranges from near 50-80%. Winds are forecast to abate through the day on Sunday. Areas across the immediate Big Sur Coast (near and just north of Point Sur) will be the windiest, with chances for winds to top out between 40-45 mph around 40%.

Finally, the opportunity for isolated thunderstorms exists on Saturday afternoon and evening. After the initial band of precipitation late tonight into Saturday late morning exits to the east, partial clearing may aid in destabilization. With CAPE values forecast to increase to around 200 J/kg and mid-level lapse rates approaching 8 C/km, there will be a potential (20-25%) for vigorous showers and isolated thunderstorms. Showers and storms will be mostly capable of producing copious amounts of small hail, which may result in brief hazardous driving conditions due to hail accumulation on Saturday afternoon and evening. Certainly don't be fooled by clearing skies earlier in the morning as this may increase the chance for an afternoon shower or storm with hail at your location. Some of the short term guidance this morning DID increase PoPs Saturday afternoon and into Saturday evening, particularly across the South Bay, Santa Cruz, Monterey, and San Benito counties. Make sure you remain weather aware tomorrow afternoon.

Lingering showers with a thunderstorm or two are forecast through early Sunday with pleasant conditions thereafter. We'll have more on the nicer weather in the long term forecast a bit later on today.

LONG TERM
(Sunday night through next Thursday)
Issued at 1217 PM PDT Fri Apr 12 2024

Drying conditions are expected to return by Sunday evening as the mid/upper level low pushes further inland and away from the region.
This too will kick off a warming trend from Monday through next Friday with high temperatures expected to reach the mid 60s to low 70s near the coast and near 80 degrees inland by Thursday/Friday.
However, by Tuesday broad troughing is expected over the Great Basin that will result it the potential for offshore flow across the interior. The pattern then shifts to high pressure building in from the Pacific by late week. Overnight lows will generally be in the 40s region-wide much of next week and lower 50s by late week. Dry weather conditions are also expected throughout next week.

AVIATION
(18Z TAFS)
Issued at 1145 AM PDT Fri Apr 12 2024

A mix of VFR and MVFR at the present time, with a brief window of VFR at most sites by 20-21 UTC this afternoon. Increased winds (becoming more southerly) are forecast this afternoon with sustained winds near 10-15 knots and gusts in the 20 to 25 knot range. The timing of -SHRA has been updated for the latest trends in obs and model guidance. At this juncture, a band of SHRA will overspread North Bay TAFs between 04-07Z on Saturday and the remaining aerodromes between 07Z-10Z Saturday. MVFR will accompany precip along with potentially higher westerly wind gusts closer to 30 knots.

Vicinity of SFO...Cigs continue to lift late this morning and by 21 UTC, I expect our brief window of VFR to prevail until later this evening. SW'ly wind gusts near 25 knots are forecast for this afternoon, with a potential that gusts subside below 20 knots ahead of the band of -SHRA approaching from the west. For simplicity sake, we'll carry 25 knot gusts through much of the period. Confidence in prolonged MVFR stratus prior to 06 UTC Saturday isn't high, but there are some indications that intermittent MVFR is warranted a few hours before. Confidence is medium to high with regard to SHRA timing. As noted above, a brief 3-4 hour westerly wind shift around 09 UTC Saturday may accompany SHRA and we may advertise this in a TEMPO group in later issuances. The chances for IFR remain below 30%, so for now we'll omit this from the TAF. There could be a brief lull in precip later Saturday, but confidence in the timing is too low.
Instability does build tomorrow afternoon, and inclusion of VCTS (also approaching from the west) may be warranted in future TAF issuances.

SFO Approach Bridge...Similar to SFO.

Monterey Bay Terminals...MVFR cigs continue to plague MRY and SNS with VFR not returning until closer to the 20-23 UTC time frame.
VFR will be very temporary with MVFR cigs returning just prior to midnight Saturday. SHRA will approach MRY initially as a band of precip approaches from the west. The SHRA coverage is forecast to diminish briefly late morning and into the early afternoon. While beyond the valid time period for this TAF set, another round of SHRA, potentially with embedded TS, may be needed for Saturday afternoon.
