Inland Heat Returns
Hot weather will return to inland areas over the next few days as a ridge of high pressure nudges in from the east. The ridge will also compress the marine layer which will also cause some warming at the coast. We will remain in (northwesterly) onshore flow, which will keep most coastal areas moderated. However, because of the compressed marine layer, fog may be more likely in the nights/mornings. The ridge will wobble a bit this weekend which should allow for some cooling and allow for some monsoon moisture to be drawn north, though at the moment it looks like we’ll just see some mid-level clouds.
AIR QUALITY: Good
Overnight: Patchy low clouds & fog around the bay and into nearby valleys. Fog could be dense in some areas. Expect lows in the low to mid 50s on the coast with mid 40s to mid 50s for inland valleys and upper 50s to 60s up in the hills.
Thursday: Clouds/fog retreat back to the coast by mid-morning with a few low clouds lingering on the south side of the bay during the afternoon. Otherwise, sunny and warmer with coastal highs in the mid 60s to low 80s—warmest on the north side of the bay—80s-90s for the lower valleys, and 90s-100s in the higher valleys. Breezy northwesterly onshore winds becoming windy up valleys late in the day.
**HEAT ADVISORY**
…for the higher terrain of Monterey County (above 1,000ft) and San Benito County (above 500ft), and the Santa Clara Valley and Diablo Range in Santa Clara County in effect from 10Am Thursday until 11PM Friday
*Temperatures up to 100(+) expected.
*Moderate HeatRisk across inland areas. This level of heat affects individuals sensitive to heat, especially those without effective cooling and/or adequate hydration.
*Friday will be the peak of the event.
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.
Friday: Patchy AM fog for the coast, then sunny and warmer yet with coastal highs in the upper 60s to mid 80s and widespread 90s-100s, up to around 108ºF inland. Breezy northwesterly onshore winds becoming windy up valleys late in the day.
Extended: We’ll cool down a bit this weekend with an increase in coastal low clouds and some high clouds will enter the picture from the south. Temps warm back up inland early next week but may stay fairly steady on the coast. Some uncertainty does remain for the coastal forecast next week, so stay tuned.
