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
(Today and tonight)
Issued at 132 AM PDT Sun Jul 21 2024

A deeper marine layer this morning to about 1000-1500 feet, per the vertical profilers. This is allowing cooler overnight temps reaching further inland, and much cooler temps reaching some parts of higher elevation areas. For example, most locations are running about 4-5 degrees cooler than 24 hours ago, while locations above about 1000 feet are running 10-20 degrees cooler.
Temps will still heat up nicely this afternoon across the area, generally running a couple of degrees cooler than yesterday.
However, this just goes to show how much a subtle deepening of the marine layer can do for overnight relief from the heat at these higher elevations. Due to the departing shortwave trough and 500 mb heights rising once again, today will be the last day before temperatures start to rise yet again through the early part of the week.

LONG TERM
(Monday through Saturday)
Issued at 132 AM PDT Sun Jul 21 2024

First, let's talk about the heat. An Excessive Heat Warning has been issued for far inland areas of the East Bay, eastern Santa Clara county, and interior Monterey and San Benito counties. These are areas where overnight recovery is a concern, where highs will be near the 100s and lows may struggle to get below about 72. A Heat Advisory has been issued for the inland North Bay, Santa Cruz Mtns, Santa Clara Valley, and the southern Salinas Valley. These are areas that will be hot with highs in the 90s to near 100, but will see better overnight cooling thanks to the marine layer remaining mostly intact and returning to inland valleys overnight.
All heat-related highlights are valid from Monday morning until Wednesday night. Confidence that Tuesday and Wednesday will be the peak of the heat is on the higher side, with temps starting to come down a bit by Thursday. As we get into the event, there is the possibility of extending heat highlights through Thursday, but will need to wait to gain more confidence on how much temps will cool through the latter half of the week. Guidance continues to advertise at-or-below normal temps by next weekend.

Now, let's talk about thunderstorms. The juxtaposition of the broad high over the Great Basin and a weak upper low set to move up the southern West Coast this week will aid in advecting some monsoonal moisture from the south. How close the upper low passes relative to the coast could be the moderating factor in how much of the upper level instability overlaps with the moisture. Current guidance advertises the low a little far out at sea, which limits the upper level cooling and puts a hamper on 700-500 mb lapse rates, thus, limiting elevated convection potential. However, there will remain some degree of marginal instability as the plume of moisture advects across our area, so we can't rule out a dry thunderstorm or two, particularly Tuesday evening into Wednesday.
For now, the chance is very low, but non-zero.
