Bay Area residents can expect typical summer-like weather to hold steady through the early part of the week, according to the latest National Weather Service forecast. Temperatures are set to dip below seasonal averages later in the week as an upper level trough rolls in. While inland temperatures will stay around the mid to upper 70s, a few areas in the North and East Bays might see the mercury climb into the low 80s.

For those clinging to the coast, the stratus cloud cover is playing its usual game of cat and mouse, largely limiting warming and keeping temperatures in the upper 50s to low 60s range. Rising to gale force at times, the winds over the coastal waters should keep the marine layer at bay, with consistent strata confined mostly around the coastline. According to a National Weather Service update, Tuesday is the toastiest day this week, with inland sizzling up to the mid 80s, a few degrees hotter than originally predicted.

A heat advisory isn't in the cards yet, but sensitive groups, including the very young or elderly, should heed the warnings to drink plenty of water and seek shade. The forecasted slight uptick in temperatures Monday through Wednesday will carry only minor heat risks for most of the Bay Area, including Santa Cruz Mountains, Salinas Valley, and portions of the Monterey Peninsula. Minor heat risk is expected throughout most of the Bay Area and Central Coast as slightly above average temperatures persist, "People who are incredibly sensitive to heat should take precautions while outdoors and remember to drink plenty of water," the National Weather Service advises.

Looking ahead, the upper-level trough promises to bring cooler temperatures starting Friday, though it appears stingy on wet relief—the chances for precipitation are looking slim. And while the winds of change are upon our marine friends, with robust northwesterlies stirring up the coastal waters, mariners should note that conditions look to soothe by the weekend. In the meantime, the National Weather Service has hoisted a Small Craft Advisory, which extends into midweek for parts of the waters, with a Gale Warning for others.
