Waning days of May generate summer-like heat
SOUTHLAND - (INT) - A strong ridge of high pressure is building over California giving the Southland some pre-summer temperatures this week.
The highest numbers will bring an Excessive Heat Warning to the deserts through Friday where highs in the Coachella Valley could approach 110. Triple digits are likely across the inland valleys.
There is a sharp thermal transition between the deserts and the coast where a strong inversion may lead to some May Gray. A sea breeze and a shallow marine layer will cover the beaches.
By Friday, look for a cut-off low to approach the coast helping to flatten the intense high pressure ridge. That should help spread cooling inland.
