Message summary: ...extended heat today through wednesday across the san francisco bay area and central coast...
.a long duration heat wave will impact the region today through at least wednesday of next week, and possibly beyond. Excessive heat will target interior locations for the full duration of the heat event, with persistent daily afternoon highs in the upper 90s to mid 100s across the interior. Drastic temperature differences will exist from the coast to the interior and communities just a few to several miles inland may experience rapid warming into the upper 80s to 90s on individual days. In addition, minimal overnight relief is expected for locations above 1000 feet where warm overnight lows will hover in the upper 60s to low 80s. Due to the long duration of this event, accumulating heat stress will be a significant impact for the general public, pets, vegetation, and livestock across the region, particularly those sensitive to the heat. Relatively cooler conditions are expected to persist near the immediate coast with highs in the 70s to 80s, though wind sheltered coastal areas could rise into the 90s or even locally 100.
