High probability for low clouds to remain at the coast today and will then penetrate inland into the coastal valleys tonight. This is as an approximately 2,000 foot marine layer remain in place across the region and is expected to deepen slightly overnight and into Tuesday morning. As such, do expect coastal drizzle in the favored spots overnight into early Tuesday. ∨

With the cut off upper level low pressure centered just west off of the Bay Area/Central Coast, expecting another cooler than normal day for Tuesday. The interior will clear out by Tuesday afternoon with mostly sunny sky conditions. High temperatures on Tuesday will be in the mid 70s to 80s across the interior and upper 50s to 60s along the coastline (some 5–15° below average). The cooler coastal areas is where clouds are forecast to persist though much of the day. ∨

(TUESDAY NIGHT THROUGH NEXT SUNDAY) [DISC]

Tuesday into Wednesday, the closed low offshore will start to weaken and shift northward before gradually moving inland along the Oregon/California border. At the same time, upper level ridging over the Four Corners [intersection of UT, CO, NM & AZ] region will start to compress and spread into Southern California. The center of the high pressure will be located over Southern California, southern Nevada, and Arizona where heat products are set to go into effect for those regions later this week. The forecast is a little more uncertain for the Central Coast and Bay Area. To start things off, a warming trend is on track to begin Wednesday with most sites to see near seasonal temperatures as highs warm back into the 80s across most of the interior. While high pressure builds across Southern California Thursday and Friday, the upper level pattern shows a flatter, more zonal to slight troughing over the Bay Area. While we are expected temperatures to continue warming Thursday and Friday, the more zonal to slight troughing will help to keep temperatures slightly cooler than those to our south with highs in the upper 80s to mid 90s. The hottest locations continue to be the southern most portions of the interior Central Coast which is on the edge of the center of the high pressure over Southern California. Temperatures across the interior Central Coast will be in the mid 90s to low 100s Thursday and Friday. In terms of heatrisk, pockets of moderate heatrisk continue across urban in the Bay Area, interior North Bay mountains, and far interior Central Coast. Remember to take breaks and drink plenty of water if participating in outdoors activities on Thursday and Friday. Temperatures cool slightly into the 80s to 90s over the weekend upper level troughing becomes slightly more distinct across Northern California. Temperatures across the interior Central Coast will remain fairly stable in the mid 90s to low 100s over the weekend as high pressure continues over Southern California. A few isolated pockets of moderate heatrisk will continue across urban areas and the North Bay interior mountains but will not be widespread enough to be very impactful. Winds remain light and onshore through this weekend with locally breezier winds across mountain gaps and passes (Altamont Pass, Salinas Valley). ∨

TUESDAY INTO WEDNESDAY, THE CLOSED LOW OFFSHORE WILL START TO
WEAKEN AND SHIFT NORTHWARD BEFORE GRADUALLY MOVING INLAND ALONG
THE OREGON/CALIFORNIA BORDER. AT THE SAME TIME, UPPER LEVEL
RIDGING OVER THE FOUR CORNERS REGION WILL START TO COMPRESS AND
SPREAD INTO SOUTHERN CALIFORNIA. THE CENTER OF THE HIGH PRESSURE
WILL BE LOCATED OVER SOUTHERN CALIFORNIA, SOUTHERN NEVADA, AND
ARIZONA WHERE HEAT PRODUCTS ARE SET TO GO INTO EFFECT FOR THOSE
REGIONS LATER THIS WEEK. THE FORECAST IS A LITTLE MORE UNCERTAIN
FOR THE CENTRAL COAST AND BAY AREA. TO START THINGS OFF, A WARMING
TREND IS ON TRACK TO BEGIN WEDNESDAY WITH MOST SITES TO SEE NEAR
SEASONAL TEMPERATURES AS HIGHS WARM BACK INTO THE 80S ACROSS MOST
OF THE INTERIOR. WHILE HIGH PRESSURE BUILDS ACROSS SOUTHERN
CALIFORNIA THURSDAY AND FRIDAY, THE UPPER LEVEL PATTERN SHOWS A
FLATTER, MORE ZONAL TO SLIGHT TROUGHING OVER THE BAY AREA. WHILE
WE ARE EXPECTED TEMPERATURES TO CONTINUE WARMING THURSDAY AND
FRIDAY, THE MORE ZONAL TO SLIGHT TROUGHING WILL HELP TO KEEP
TEMPERATURES SLIGHTLY COOLER THAN THOSE TO OUR SOUTH WITH HIGHS IN
THE UPPER 80S TO MID 90S. THE HOTTEST LOCATIONS CONTINUE TO BE
THE SOUTHERN MOST PORTIONS OF THE INTERIOR CENTRAL COAST WHICH IS
ON THE EDGE OF THE CENTER OF THE HIGH PRESSURE OVER SOUTHERN
CALIFORNIA. TEMPERATURES ACROSS THE INTERIOR CENTRAL COAST WILL BE
IN THE MID 90S TO LOW 100S THURSDAY AND FRIDAY. IN TERMS OF
HEATRISK, POCKETS OF MODERATE HEATRISK CONTINUE ACROSS URBAN IN
THE BAY AREA, INTERIOR NORTH BAY MOUNTAINS, AND FAR INTERIOR
CENTRAL COAST. REMEMBER TO TAKE BREAKS AND DRINK PLENTY OF WATER
IF PARTICIPATING IN OUTDOORS ACTIVITIES ON THURSDAY AND FRIDAY.
TEMPERATURES COOL SLIGHTLY INTO THE 80S TO 90S OVER THE WEEKEND
UPPER LEVEL TROUGHING BECOMES SLIGHTLY MORE DISTINCT ACROSS
NORTHERN CALIFORNIA. TEMPERATURES ACROSS THE INTERIOR CENTRAL
COAST WILL REMAIN FAIRLY STABLE IN THE MID 90S TO LOW 100S OVER
THE WEEKEND AS HIGH PRESSURE CONTINUES OVER SOUTHERN CALIFORNIA. A
FEW ISOLATED POCKETS OF MODERATE HEATRISK WILL CONTINUE ACROSS
URBAN AREAS AND THE NORTH BAY INTERIOR MOUNTAINS BUT WILL NOT BE
WIDESPREAD ENOUGH TO BE VERY IMPACTFUL. WINDS REMAIN LIGHT AND
ONSHORE THROUGH THIS WEEKEND WITH LOCALLY BREEZIER WINDS ACROSS
MOUNTAIN GAPS AND PASSES (ALTAMONT PASS, SALINAS VALLEY). [DISC]

As mentioned in the short term, both small and large fuels are drying out with warmer temperatures increasing the likelihood of further drying Wednesday into the weekend. This does result in localized elevated fire weather concerns, particularly across the higher elevations above the marine layer, Wednesday through the weekend. While winds remain fairly light and onshore, small fuels have cured and larger fuels are drying out so extreme caution is needed if participating in any outdoor activities involving sparks or flames. Remember, most wildfires are started by human activities. One less spark, one less wildfire. ∨

IFR [Instrument Flight Rules] and MVFR [Marginal Visual Flight Rules] ceilings are building along the coast and are filling around the Monterey Bay and look to fill over the terminals into the early evening. Winds reduce across the region into the evening and ceilings look to fall further and become more widespread later into the night, affecting the North Bay and SF Bay terminals as winds continue to reduce. Inland clearing begins in the mid morning with most TAF [Terminal Aerodrome Forecast] sites going VFR [Visual Flight Rules] in the late morning. The exception will be haf, which keeps ceilings through the TAF [Terminal Aerodrome Forecast] period. Winds look to stay light to moderate through the morning and increase into late Tuesday morning and afternoon. Expect winds to reduce into Tuesday evening as IFR [Instrument Flight Rules]/MVFR [Marginal Visual Flight Rules] ceilings begin to move inland from the coast, filling over the SF Bay and Monterey Bay terminals, and the rest of the terminals later that night. ∨
