We have one more day of scattered storms in store as low pressure aloft opens up into a trough and interacts with the seabreeze in the afternoon. 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.

The sun returns on Tuesday

/ at 8:40 AM

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.
