Rest of the week: Heat’s turning back up

After a brief reprieve Tuesday, the heat is turning back up as we head into the Fourth and beyond. Winds stay onshore for one more day Wednesday, which will keep temperatures “only” in the upper 80s to low 90s. Mid-70s dewpoints, though, will make it feel like the upper 90s during the height of the afternoon. Ridging building in aloft will keep a lid on any shower and thunderstorm development.

Tuesday: Not quite as hot, a stray shower or storm possible

/ July 1, 2024 at 10:32 PM

We get a brief reprieve from the heat on Tuesday as the front that brought today’s deluge nudges just south enough for a little bit of cooler and drier air to work in, especially further inland. Mostly cloudy skies will be the rule as onshore flow persists throughout the day. We start the day in the low 70s, but dewpoints sneaking briefly back into the upper 60s could feel a little bit better than we’ve felt. Those dewpoints will start to creep back up, but the cloud cover and onshore flow keeps highs capped to the mid-80s. A stray storm can’t be totally ruled out near the coast; in fact some model data suggests a few downpours will be possible before sunrise. Wait and see on that, but most of us should get Tuesday in rain-free.
