Inland Heat Lingers; Coast Gets a Break
The strong ridge of high pressure that has brought record heat to the region will remain firmly in place through Wednesday. In fact, some inland areas will see their hottest temperatures of the week Wednesday afternoon. In contrast, coastal areas will actually be a bit cooler as the sea breeze kicks in earlier. By Thursday, the ridge 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 flow. As it passes, southerly winds, increase moisture & clouds, and even a few showers/thunderstorms will be possible. The pattern will be a bit more active next week as a weak trough centers in over the coast—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 Thursday.
Those most vulnerable to the heat should still take necessary precautions through this prolonged period of heat.
Expect an extended period of hot daytime temperatures with limited overnight relief. Near record to record temperatures are possible during the peak of the heat event. Daytime temperatures likely to peak on Tuesday and/or Wednesday.
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 on the hottest days of Tuesday and Wednesday. The Santa Cruz coast could rise to the upper 80s to low 90s during these hottest days. 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 in the
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.
Wednesday: Sunny and warm once again. The sea breeze will kick in earlier on the coast and may be a bit stronger in the afternoon. Expect coastal highs in the upper 60s to low 80s while inland areas remain in the 90s to around 105ºF. Breezy conditions will reach major inland valleys in the afternoon.
Overnight: Low clouds will fill the bay with patchy fog possible. Expect coastal and inland valley lows in the 50s with 60s to 70s up in the hills.
Thursday: Patchy fog on the coast in the morning, otherwise sunny. Cooler for most areas with a mix of high and low clouds on the coast late. Expect coastal highs in the 60s-70s with mid-80s to around 100ºF inland. Breezy in the afternoon.
Extended: Southerly winds and clouds will be on the increase Friday and all areas will experience significant cooling except areas on the south side of the bay which may warm up a bit. A low will pass by overnight into Saturday which may spawn a few showers/thunderstorms out over the water or along the immediate coast. Much more seasonable weather can be expected Sunday into next week and some clouds will likely remain in the forecast.
