High pressure is building into the region and will strengthen through the end of the week. This means some of the hottest temps we’ve felt all year will happen during this time. The heat will peak Thursday and Friday with a few records expected to be broken.

The high pressure system will drift a little South on Saturday and offshore winds will switch around to onshore. This will mean temps will be a little cooler but will stay above average.

Looking ahead to the weekend, temps will begin to drop 4-8 degrees each day, starting Saturday. By Sunday, we’ll cool back down to the 60s & 70s. A little ridge of high pressure pops back up Monday and Tuesday bringing temps to the 60s, 70s & 80s.
