Back To Local Summer

High pressure builds in from the west Sunday into Monday. Compression of the marine layer will cut back on coastal clouds and allow for warmer temperatures near the coast. The initial impact will be an increase in coastal fog Sunday morning, however! Temperatures will peak for most areas on Monday, though the Monterey/Seaside area may be a little warmer Tuesday as surface winds switch to the south. Low clouds will then thicken with cooler weather for all on Wednesday.

AIR QUALITY: Good to Moderate

Sunday: Mostly sunny with some fog right along the coast. Warmer with coastal highs in the mid 60s to mid 70s and upper 70s to upper 90s inland. Windy up valleys late in the day.

Monday: Patchy AM fog right along the coast, otherwise mostly sunny with a few high clouds passing through. Warmer, with coastal highs in the 70s to mid 80s and mid 80s to around 102ºF inland. Windy up valleys late in the day.

**HEAT ADVISORY**
…for the Santa Cruz Mountains in also the KION coverage area in Santa Clara County in effect from 11AM Monday until 8PM Monday

*High temperatures in the mid to upper 90s expected.

*Moderate HeatRisk in the warned areas. This level of heat affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.

Heat stroke is an emergency! Call 9 1 1.

Extended: Temperatures will cool a bit on Tuesday and then significantly on Wednesday as a lower pressure aloft allows for a deeper marine layer. We’ll see some balance late in the week with more seasonable weather.
