Toasty Temps Return, Some Relief at the Coast
Temperatures head upward for most areas on Wednesday after brief cooling on Tuesday. High pressure to our east nudges back in, leading to that warming, which will be felt most across the northern half of the viewing area where inland/mountain highs may jump 5-10ºF. The ridge will begin to ease again with a subtropical low to our south exerting a stronger influence. Initially, inland areas will retain the heat and the easterly flow in the mid-levels will likely help disrupt the marine layer and warm coastal areas by a few degrees as well. Then, further weakening of the ridge and the proximity of the low will help cool all areas into the weekend. See more below in the extended section about what else may pop up!
AIR QUALITY: Good to Moderate
***EXCESSIVE HEAT WARNING***
… for the higher elevations (above 1000ft) of Monterey County and the mountains and higher elevation valleys (above 500ft) of San Benito County until 8PM Friday
*Dangerously hot conditions with temperatures up to 110.
*Most individuals will be at risk for heat-related illnesses without effective cooling or adequate hydration, especially with prolonged outdoor exposure. Without effective cooling and/or adequate hydration, heat-related illnesses including heat stroke will be a risk to everyone. Overnight lows will warm as well leading to poor relief from the heat specifically in elevated terrain and interior areas.
*An exceptionally dangerous situation continues to unfold over the next couple of days we continue to move through this deadly heat event for inland areas. Another couple days of temperatures well above normal will lead to compounding effects among people and infrastructure, with the possibility of numerous heat related fatalities.
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.
***EXCESSIVE HEAT WARNING***
…for the Santa Clara Valley and the Diablo Range in Santa Clara County in effect NOW until 8PM Friday
*Dangerously hot conditions with temperatures up to 106 to 110 with limited overnight cooling in higher elevations expected.
*Most individuals will be at risk for heat-related illnesses without effective cooling or adequate hydration, especially with prolonged outdoor exposure. Without effective cooling and/or adequate hydration, heat-related illnesses including heat stroke will be a risk to everyone.

**HEAT ADVISORY**
…for the Santa Cruz Mountains, and the lower elevation valleys of Monterey (<1000ft) and San Benito (<500ft) counties in effect NOW until 8PM Friday.
*Temperatures up to 106 expected.
*Those sensitive to heat, such as the homeless, elderly, children, and pets will be at risk for heat-related illnesses. Those without effective cooling and/or adequate hydration will be at the greatest risk.
* ADDITIONAL DETAILS...Despite the downgrade from an Excessive Heat Warning to a Heat Advisory, the long duration of this heat wave will cause cumulative effects and this situation
remains dangerous.

Wednesday: Low clouds retreat the coast but linger on the south side of the bay and the outer Monterey Coast. Slightly warmer with coastal highs in the low 60s to mid 70s—warmest on the north side of the bay—and a range from upper 70s to mid 90s for near coastal valleys and 90s to around 108ºF for higher and farther inland valleys. Windy up valleys late in the day.
Overnight: Clouds will thicken at the coast, filling the bay and nearby valleys into the morning. Mostly cloudy at the coast, partly cloudy to mostly clear inland. Lows mainly in the 50s, with higher valleys and peaks warmer in the 60s and 70s. Patchy fog possible around dawn.
Thursday: A few low clouds in the morning, then sunny for most of the day with high clouds moving in from the south late. Warmer, with coastal highs in the mid 60s to around 80ºF, 80s-90s for near coastal valleys, and 90s to around 107ºF for higher and interior valleys. Windy up valleys late in the day. Areas of smoke possible, mainly in the mountains.
Extended: Temperatures start to cool down on Friday and will be more noticeable on Saturday as low clouds return to the coast. Mid to high level monsoonal moisture streams in from the south as well and there may be a slight chance at convention on Saturday—stay tuned. Beyond the weekend, more seasonable weather is expected next week.
