Patchy fog hung over low-lying San Jose neighborhoods early today, but it will not stick around for long. Skies are expected to clear quickly, turning the day sunny with a high near 69°F. Mornings stay on the cold side, with lows in the low 40s for valley neighborhoods and upper 30s in the hills, followed by mild and breezy afternoons. Today will be the coolest day in what is shaping up to be a short warm stretch later this week.
Afternoon Winds Pick Up
Light west winds in the morning are forecast to shift northwest and strengthen through the afternoon, with gusts most noticeable on bridges and exposed hilltops. Cyclists and drivers of high-profile vehicles should be ready for sudden crosswinds during the midday commute, especially in the usual wind-prone spots.
Warming Trend and Marine Advisories
According to the National Weather Service, a quick warming trend kicks in tomorrow, with inland highs in the 70s, 80s by Thursday and Friday, and 85°F and above over the weekend, with scattered 90s possible early next week. The agency also calls for a widespread Minor HeatRisk from Wednesday through Saturday, with increasing pockets of Moderate HeatRisk by Sunday into early next week. Marine advisories and gale warnings are posted for parts of the coastal waters through tonight, so small boats should plan accordingly and check conditions before heading out.
Stay Cool, Plan Ahead
With heat risk on the rise later in the week, Santa Clara County officials recommend staying hydrated, avoiding strenuous outdoor work during peak afternoon hours, and lining up nearby cooling options if you do not have air conditioning. Local resources and cooling-center information are available from the Santa Clara County Office of Emergency Management.
What To Expect This Week
Look for foggy starts and mostly sunny afternoons through midweek, so layer in the morning, then use sun protection once things warm up.
