It was another pleasant day across the county, with temperatures trending near to 5 degrees below average. Expect subtle day-to-day changes through Thursday, with morning clouds clearing to sunny skies and temperatures in the 60s and 70s at the coast, 70s and 80s inland to the mountains, and low 100s in the deserts.
It will become much warmer starting on Friday, right on cue for the start of summer. The summer solstice happens at 1:50pm this Thursday.
A heat dome impacting much of the east will expand westward for the first days of summer, which means most of the country will be dealing with above-normal temperatures. Locally, expect temperatures to top out 5 to 10 degrees above average, which will take temperatures into the 90s for the inland and mountains and between 110 to 115 in the deserts, where an Excessive Heat Warning will likely be issued later this week. The coast will also be warming to the mid-70s to a few low-80s.
The marine layer will be shallower by the weekend bringing more sunshine to the coast and valleys.
The heat peaks this weekend with only a slight dip in temperatures into next week. This will be a long stretch of warmer than normal temperatures so be sure to take precautions to keep cool.
Sunday through Tuesday, we're likely to get our first surge of monsoon moisture of the season over the mountains and deserts. There doesn't appear a chance for any storms at this time, but it will feel muggier. Overnight temperatures will also be getting warmer, which means we won't get much relief from the heat at night.
Tips to Stay Safe in the Heat this Summer:
Excessive heat is a danger to anyone, especially those with respiratory issues, people that work outdoors, children and the elderly. Make sure outdoor pets have safe shelter and cool water. Cars turn into ovens in a matter of minutes so be sure to check the back seat and never leave children or pets in the car. Wear light-weight, light-colored, loose-fitting clothing and stay hydrated! Avoid strenuous outdoor activities, enjoy air conditioning whenever possible and if you're working in the heat make sure to take breaks often and drink plenty of water.
