INLAND EMPIRE – (INT) - A transition in Southern California’s weather is coming.

With the arrival of a new month, May Gray was right on schedule. But the night and morning low clouds across the inland valleys aren’t the only features of a highly variable weather scenario.

A warming trend is expected late this week and into the weekend.

Temperatures will rise around 10-20 degrees above normal for inland areas, valleys, and mountains, and around 8-10 degrees above normal for coastal areas.


A meandering, cut-off low is taunting the coastline giving fits to forecaster’s predictions for the next couple of days. It’s created a marine layer 5-thousand feet thick, morning drizzle from the coast into the valleys and potent winds in the deserts strong enough to create stir up clouds of dust.

This system has brought much cooler weather to most of the Southland. But the atmosphere will shift gears beginning Wednesday with the onset of drier, warmer temperatures. The area of low pressure will exit Southern California and replaced with high pressure expected to expand into the end of the week.
