Seasonable Morning Transitions into a Warmer Afternoon
Temperatures head back upward starting Monday—both for the coast and inland areas! High pressure to our east pushes back into California and will sit over us for the next few days, squashing the marine layer and bringing a hot air mass back in over the state. Heat alerts will be in place for inland areas with highs expected to be between 5-15ºF above normal. The coast will warm up too, but mainly just into the 70s for most areas! Coastal cities will see warmer temps come Tuesday. Some monsoon moisture will stream into the area from the south on Wednesday, which we are watching, but at the moment, it’s looking pretty uneventful—but stay tuned.

Monday: Remaining low clouds give way to mostly sunny skies inland, remaining patchy on the south side of Monterey Bay. High clouds will move in from the south by late afternoon. Expect warmer temperatures with coastal highs in the mid 60s to mid 70s, and upper 70s to around 102ºF inland. Windy up-valleys late in the day.
Overnight: Low clouds will increase, mostly to partly cloudy conditions near the coast. Fog, dense is spots, possible. Inland areas will remain mostly clear with some high clouds passing through from the south. Lows will be warmer with mid to upper 50s for most. 60s and 70s in the hills and high valleys.
Tuesday: Passing high clouds, otherwise sunny and warmer with highs in the upper 60s to low 80s on the coast and 80s to around 105ºF inland. Windy up-valleys late in the day.
Extended: The warmest day of the week would probably be Wednesday were it not for the high cloudcover moving through. This monsoon moisture has an outside chance of producing a high based shower or dry thunderstorm, but the probability remains low. In the meantime, it may feel just a touch more muggy than normal around the area. Dryer air begins to move in Thursday as the ridge moves back to the southeast and troughing develops on the West Coast. This will be the start of a cooling trend that will last into the weekend.
