Hot weather continues as we head into the weekend with only a slight chance at some thunderstorm-induced relief.
Read more »The main weather story for Friday and the weekend will be the unusual midsummer-like heat, especially Friday and Saturday. We may break a record high on Friday — the record high is 94° set in 1941 — as temperatures head into the mid-90s under partly cloudy to mostly sunny skies. Heat indices will peak around 100° or so — not into heat advisory territory but still on the high side for mid-May.
Partly cloudy skies continue into Saturday, though a stalling front could pop a stray storm or two especially further north. Otherwise, expect another quiet and very warm day, with highs in the mid-90s once again expected after a low-70s start. The front meanders around the area on Sunday, keeping partly cloudy skies in the forecast with a stray storm not out of the question. Temperatures should run a touch “cooler” — and by “cooler” I mean around 90° as opposed to 95°.
The 90s stick around well into next week before the next front approaches by mid-week with the next mentionable shower and thunderstorm chances.
Wednesday was the warmest day thus far of 2025, with a high of 89° recorded at the airport. This distinction will be short-lived as high pressure continues to build in on Thursday, sending us to what should be our first 90° readings of the year in the afternoon. Mostly sunny skies are expected to prevail, so be sure to apply sunscreen if you are headed outside for a little pre-summer preview.

Once again, we get off to a very mild start with lows in the upper 60s expected. Temperatures will head to the mid-80s before scattered storms initiate along and ahead of the seabreeze. Some brief downpours will be possible, but not expecting a repeat of what we saw this past weekend, either.
Read more »Much quieter weather is expected for Tuesday as a surface front moves by, shunting the plume of deep moisture that has absolutely soaked us for the past few days offshore and allowing the sun to break out. There’s still going to be some cloud cover, but we should get a good chance to dry out today.
There is going to be the risk for a few isolated storms to pop back up late today into tonight, but otherwise, it should be a good weather day with highs topping out in the low to mid-80s.
Shower and storm chances return Wednesday, but will be relatively short-lived as high pressure builds back in to close out the week, bringing us a sustained stretch of 90°+ highs and perhaps some even warmer heat indices as well.
