New SYNOPSIS, SHORT TERM, LONG TERM

SYNOPSIS
Issued at 1201 AM PDT Tue Jul 23 2024

Inland heat continues through mid-week. Excessive Heat Warnings and Heat Advisories are in effect through Wednesday evening for areas away from the coast. A cold front will bring significant relief by Friday.

SHORT TERM
(Today and tonight)
Issued at 1201 AM PDT Tue Jul 23 2024

The marine layer is holding steady at 1,000 ft which may bring some patchy areas of coastal fog later this morning, especially along the Monterey Bay. Otherwise the morning will be pretty similar to yesterday with coastal stratus early, and warm inland temperatures in the afternoon. As high pressure sets up camp over California, the 23/00Z sounding found an 850 mb temp has climbed to 24.75C, which should increase over the next 36 hours. The ECMWF ensemble shows pretty high confidence that this benchmark will reach 27C by 24/12Z. The forecast temperatures this afternoon are holding steady with somewhere around 100 degrees expected in portions of the inland East Bay and Monterey/San Benito counties.
The inland North and South Bay will be in the mid to upper 90s.
Coastal areas will remain in the typical summertime 60s and 70s.
For areas within the heat warnings, remember the following 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.

The one wildcard is a small potential for thunderstorms beginning today and persisting through Wednesday. A disturbance offshore the Baja Peninsula is deep enough to divert the subtropical jet.
The interaction between this feature and the high pressure over California will generate SW flow through the majority of the troposphere. This will pump mid-level moisture and trigger some instability. The 06Z HRRR has a decent MUCAPE of around 327 J/kg with a 99.5th percentile PWAT of 1.42" This afternoon/evening.
The 2 inhibitors are that this instability and moisture is all elevated (LCL over 15,000 ft), and there is around 200 J/kg of CIN to overcome below the instability. The newest HRRR runs are coming in with much less CAPE than earlier NAM runs. All together, there is currently less than a 10% chance for thunderstorms to develop, so it won't be mentioned explicitly in our forecasts.
There should at least be some interesting mid-level clouds that could make for a nice sunset this evening.

LONG TERM
(Wednesday through Monday)
Issued at 1201 AM PDT Tue Jul 23 2024

No major change to the long term forecast tonight. High pressure will reamin over California through Thursday. By Friday, the subtropical low in the E. Pacific will move north and be picked up by the jet stream before moving inland on Friday. This will be followed by a cold front that will flip the mid and upper-level winds from SW to NW, and usher in a cooler air mass. While these subtropical disturbances can be hard to forecast, this is not a small disturbance that takes a little bite out of the high and brings a day or two of cooler weather. This is a significant regime change. This is what we've been waiting for since the 4th of July.

For inland areas dealing with the heat, today will be the hottest day of the week, but the cooling will begin to accelerate soon.
Expect the max temp to drop a few degrees Wednesday, another 5 or so Thursday, and a further 10 degrees on Friday. The weekend temps look great, but the price for that cooling is morning clouds and afternoon wind. San Francisco and Salinas will be in the 60s, Santa Rosa, Napa and San Jose in the upper 70s, and Concord and Livermore will be in the mid 80s. It was a long, hot July. Enjoy the cooler weather this weekend.

AVIATION
(06Z TAFS)
Issued at 1118 PM PDT Mon Jul 22 2024

Coastal stratus and fog /LIFR-IFR/ conditions prevail along the immediate coastline northward to around Point Reyes per satellite imagery and surface observations. Otherwise it's VFR across the forecast area. The marine layer varies in depth from 1,000 feet at Fort Ord to a few hundred deep at Bodega Bay per recent profiler data. A 5.2 mb ACV-SFO pressure gradient (northerly wind)
predominates and is juxtaposed to a 1.5 mb SMX-SFO pressure gradient and 2.3 mb SNS-SJC (southerly wind), while there's an onshore gradient of 2.3 mb SFO-SAC.

A wild card in the coastal stratus and fog coverage is the incoming higher precipitable water (higher water vapor) arriving from southern California and how it may or may not affect coastal stratus and fog coverage later Tuesday and Tuesday night. Inland terminals are high probability VFR, however it's low confidence if coastal terminals may have patchy LIFR-IFR conditions nearby later today and tonight.

Vicinity of SFO...VFR. West wind near 10 knots, increasing to 15 knots Tuesday afternoon and early evening, then decreasing to less than 10 knots late evening and overnight.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...LIFR-IFR in coastal stratus and fog tonight and Tuesday morning. Conditions improving to MVFR-VFR during the day, mainly later in the morning. For now indicating VFR in the terminal forecasts, however patchy coastal stratus and fog /LIFR-IFR/ may be nearby Tuesday night.

MARINE
(Tonight through next Sunday)
Issued at 852 PM PDT Mon Jul 22 2024

Northwesterly breezes reduce through the night but still remain hazardous in the northern outer waters. Significant wave heights will abate through the forecast period. Non-zero thunderstorm chances exist for Tuesday into Wednesday.

MTR WATCHES/WARNINGS/ADVISORIES
CA...Coastal Flood Advisory until 2 AM PDT early this morning for CAZ006-506-508.

Heat Advisory until 11 PM PDT Wednesday for CAZ503-504-506-512- 513-516.

Excessive Heat Warning until 11 PM PDT Wednesday for CAZ510-514- 515-517-518.
