A Cooling Trend
Thursday, the ridge of high pressure that brought record heat to the region will begin to shuffle eastward allowing a cut-off low pressure some room to make an approach from the southwest. That low will pass by late Friday into Saturday as it is absorbed into the upper level flow. As it passes, expect gusty southerly winds, increased moisture & clouds, and even a few showers/thunderstorms. A weak trough of low pressure will then linger on the coast next week—likely to bring more seasonable weather and keep some clouds in the forecast.
*Heat Advisory*
… for San Benito and Santa Clara Counties, along with inland Monterey & Santa Cruz Counties until 7PM today.
Those most vulnerable to the heat should still take necessary precautions through this prolonged period of heat.
Heat related illnesses such as heat exhaustion and heat stroke can occur due to prolonged exposure to hot temperatures, including the general population. People most vulnerable include those who are spending lots of time outdoors, those without air conditioning, young children, the elderly and those with chronic ailments. Additional societal impacts due to the movement of people seeking relief from the heat from hotter areas inland.
Widespread 90s to low 100s daytime temperatures are expected for inland areas into Thursday. Other coastal areas should remain relatively cooler than surrounding inland areas given light onshore flow (70s to around 80). Significant temperature differences from the coast to a few miles inland could drive an excessive number of persons towards the coast to seek relief from the heat. Individuals are advised to check with local authorities on potential closures of parks and beaches and be aware of any special requirements for visiting such areas. Overnight lows will range from the upper 50s to low 60s which may limit the impact of typical overnight relief.
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children, disabled or elderly adults, 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.
Thursday: A few low clouds/fog near the coast, otherwise sunny. Cooler across the board with coastal highs in the 60s to low 70s and 80s to around 101ºF inland. Breezy for inland valleys in the afternoon.
Overnight: Widespread low clouds with patchy fog. Expect lows in the 50s, with 60s up in the hills.
Friday: Scattered high clouds and a few low clouds near the coast. Cooler, with highs mainly in the 60s-70s. Southerly winds increase and could be gusty at times, especially on the coast. Those winds may push some drizzle up into the coastal mountains late.
Extended: A low pressure center will pass by overnight Friday into Saturday which may spawn a few showers/thunderstorms. The highest threat is out over the water or along the immediate coast but an isolated threat exists inland too. Saturday may feel a bit odd as we’ll be in warm, moist southerly flow. It will feel a lot more “tropical” than most are used to in the region. The weather looks fairly seasonable for most of next week with partly cloudy skies.
