New AVIATION, MARINE

SYNOPSIS
Issued at 132 AM PDT Sun Jul 21 2024

Another day of temperatures cooling slightly and a deeper marine layer, followed by another warm up through this week. A Heat Advisory and Excessive Heat Warning has been issued for inland areas, in effect Monday morning through Wednesday night.

SHORT TERM
Issued at 105 PM PDT Sun Jul 21 2024 (This evening through Monday)

The longwave wave pattern over the West today features an upper low spinning off the PacNW coast, an embedded shortwave trough rounding the base of the upper low, and an upper ridge over NV/Desert SW being buffeted by the shortwave. What does this mean locally? The passing shortwave to the north help to nudge the ridge eastward cooling the overall airmass and keeping onshore flow with a marine layer in place. The much talked about cooldown for Sunday has come to fruition - latest 24 hour trends show even more cooling along the coast, but also the interior. Interior East Bay has cool roughly 15 degrees from yesterday to today.
While interior locations had a few 100 plus readings on Saturday, one will be hard pressed to find a 100 plus reading today. As for onshore flow, it still persists with SFO-SAC still showing 3+mb.
Still seeing gusts of 30+ mph for East Bay gaps/passes.

Tonight through Monday: The shortwave trough will continue to push northward into S Canada. Locally, high pressure that was nudged eastward will build westward. The building ridge aloft will kick off a marked warming trend across the Bay Area and Central Coast, especially across the interior. Temperature jump from Sun to Mon will be roughly 5-15 degrees. At the surface, onshore flow will remain so the marine layer will bring night/morning clouds.
The lingering marine layer will keep coastal temperatures in check for Monday as well. Forecast highs for Monday - 60s to mid 70s along the coast, 70s to near 90 SF Bay, and 90s to lower 100s interior. The hot weather inland will elevate HeatRisk to moderate to major. An Excessive Heat Warning remains for far inland areas of the East Bay, eastern Santa Clara county, and interior Monterey and San Benito counties. A Heat Advisory remains for the inland North Bay, Santa Cruz Mtns, Santa Clara Valley, and the southern Salinas Valley.

LONG TERM
Issued at 105 PM PDT Sun Jul 21 2024 (Monday night through next Saturday)

Further strengthening of the ridge will continue through Wednesday. The airmass associated with the ridge will yield 850mb temperatures in the upper 20C range. While these values are well above the 90th percentile and near the daily moving max (per KOAK sounding climo) they are not the same as what we saw earlier in July. Not expecting records to break for max temperatures.
Regardless dangerous heat is still expected and heat related hazards will remain through at least Wednesday. Tuesday will likely be the hottest day with far inland locations in the 100-108F range with major to extreme HeatRisk. These areas have the greatest likelihood for heat related illnesses. Not just for the young/elderly, but everyone who doesn't take precautions.
Stay hydrated, limit afternoon outdoor activities, and never leave pets/children in a vehicle. As previously mentioned, the marine layer will keep the coast cooler, but given the airmass potential above normal temperatures are expected. The ridge begins to shift eastward late Wednesday into Thursday as an upper level low moves northward on the western periphery of the ridge. The shifting ridge and approaching upper low will initiate a cooling. Thursday will feature some cooling inland, but more widespread cooling is expected Friday and into next weekend.

The other item of note will be the influx of upper level moisture Tuesday into Wednesday as the ridge to the east and upper low to the west allow for southerly flow aloft. PWATs will increase over the region as earlier as Tuesday, but peak Tuesday night into Wednesday at 200% of normal for late July. While there is ample moisture aloft instability is somewhat lacking. While guidance shows decent MUCAPE and marginal lapse rates, CINH/inhibition is also pronounce. Would like to see less CINH before introducing tstorms over the forecast area. For now, will keep mentioning a non-zero chance, but more likely for increasing mid-high level clouds. We'll be watching this closely as it could have big fire weather impacts.

AVIATION
(00Z TAFS)
Issued at 424 PM PDT Sun Jul 21 2024

Satellite shows some low clouds near Monterey Bay and SF Bay terminals creating a mix of VFR, MVFR, and IFR conditions. Expect ceilings to return for KSNS early this evening, followed by North Bay terminals later tonight. SF Bay terminals may clear for a moment but is expected to see IFR conditions tonight. Any terminals experiencing ceilings, will clear near 16-18Z. Onshore winds will diminish tonight to moderate but will build to breezy Monday afternoon.

Vicinity of SFO...VFR but conditions may bounce around to MVFR as some low clouds are having a hard time clearing. Ceilings are expected to return over night with low confidence on timing. Some models hint at a 06Z return, but higher confidence that near 08Z-09Z low ceilings will prevail untill 16Z Monday.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR for KMRY and MVFR for KSNS, but ceiling will lower near to KSNS. Therefore, expect IFR conditions soon after 00Z. Ceilings are expected to lower to LIFR and will clear near 18- 19Z.
