Weekly Outlook: September 15-21, 2025

We’re not going to get much, if any, relief for the drought this week across the majority of the region, but temperatures should remain comfortable.

Over the past 90 days, rainfall totals across the region are roughly 2-5 inches below average normal. Image provided by WeatherBell.

We start the week off with high pressure in control, giving us a couple of dry and warm days for Monday and Tuesday, with a seabreeze keeping coastal areas a little cooler, especially today. Wednesday and Thursday are the days with the most uncertainty at this point. We’ll still have high pressure to the north, but a low pressure area will be passing offshore. This will send in some clouds, but similar to last week’s system the question is how far north the rain shield will get. Some models keep it all offshore, several bring it up to the South Coast, some bring in farther inland. Given then the models overestimated how far inland it would get with the system last week, we’re inclined to think that the rain probably won’t get much farther inland than the South Coast, with most of it falling Wednesday night into early Thursday. The system pulls away later Thursday, then a cold front drops down from the north on Friday. The models show most of the rain with the front drying up before it gets here, so the front should move through with little fanfare on Friday. Behind it, high pressure returns with much cooler air on Saturday, though temperatures should start to moderate a bit on Sunday.

Most of the models keep what little rain we’re expecting close to the South Coast late Wednesday into Thursday. Images provided by Pivotal Weather.
