New AVIATION, MARINE

SYNOPSIS
Issued at 1134 AM PDT Sun May 5 2024

Conditions clearing out today in the wake of yesterday's front.
Cool weather to kick off the week, but a notable warm up is on the way for the latter half of the week into this weekend.

SHORT TERM
(This afternoon through Monday)
Issued at 1134 AM PDT Sun May 5 2024

Visible satellite showing ample clearing across much of the area in the wake of the cold front yesterday. Some isolated cumulus continue to form over complex terrain areas as a result of daytime heating and a hint of lingering low level instability.
However, don't expect much in the way of additional precip in these areas. There is still a bit of a hindrance in the form of some capping stability in the low to mid levels. Some areas in the highest peaks of the Santa Lucia and Santa Cruz Mtns can't rule out a sprinkle or two this afternoon, but anything outside of that seems to be a very low chance. The weather remains quiet into Monday with clear and dry conditions. Overnight temperatures into Monday morning will be on the chilly side once again, similar to last night, but we will warm up from here.

LONG TERM
(Monday night through next Saturday)
Issued at 1134 AM PDT Sun May 5 2024

Beyond Monday, the pattern shifts to become dominated by a longwave ridge settling in over the Western US. The region will remain dry through the rest of the week with temperatures gradually heating up into the weekend. As it stands, Thursday and Friday look to be the warmest as afternoon highs are forecast to rise into the mid-80s across inland valleys and 70s elsewhere.
Once again, with temps above seasonal averages by the end of the week and coming off the heels of an anomalously cold system, it is important to remind ourselves that these quick changes in temperatures can still result in heat-related illness, even with highs in the 80s. As a result, much of our area below about 3500 feet and off the immediate coast will be under a minor Heat Risk Wednesday into the weekend. This primarily affects individuals who are extremely sensitive to heat, especially when outdoors without effective means of cooling or adequate hydration.

In the longer term, any chance for rain is dismal as we inch closer to our typical summertime pattern, and a there is a slight chance that above normal temperatures persist into the following week.

AVIATION
(00Z TAFS)
Issued at 428 PM PDT Sun May 5 2024

VFR through the TAF period for all terminals, with the biggest concern will be the winds. Post frontal W/NW winds remain breezy and gusty and will slowly diminish for most terminals tonight and rebuild to moderate to relatively breezy towards late Monday morning early afternoon.

MARINE
(Tonight through next Friday)
Issued at 428 PM PDT Sun May 5 2024
