Area Forecast Discussion National Weather Service San Diego CA 831 AM PDT Fri May 17 2024

SYNOPSIS
A seasonally persistent marine layer will continue for the coming week with night and morning coastal low clouds extending well inland across the valleys with limited or slow afternoon clearing for coastal areas. There will be periods of stronger, gusty westerly winds for portions of the mountains and deserts during late afternoons and nights. High temperatures will continue slightly below normal in general, although cooler early next week.

DISCUSSION
FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES...

A fully uniform low cloud coverage west of the mountains and bright sunshine above and beyond the marine layer greet the day this morning. Some of those clouds had some depth to them overnight, producing drizzle that measured a few hundredths particularly in San Diego County and southern OC. The marine inversion this morning is strong, discouraging a full mix-out of clouds today. There's a small chance we could get some sunshine near the coast today, but don't count on it. Our daily pattern of winds in the mountains and deserts will continue, with strongest gusts 35-50 mph through mountain passes into adjacent deserts. May Gray will continue in full swing as a weak trough pattern over the West continues this coming week. Within the overall pattern, there will be shortwaves to provide barely noticeable variations on the theme. These will tweak the marine layer depth, temperatures and strength of winds in the mountains and deserts from day to day. A trough of low pressure will move through the West and pick up a weak low currently off the coast to our west.
Models are pretty certain that Monday will feel the biggest effects from this well-defined feature: a deeper marine layer, stronger winds in mountains and deserts, and cooler regionwide.
Tuesday and beyond, the timing and strength of shortwaves vary more with a wider spread of ensemble solutions. But none of the solutions indicates any big change in our overall pattern. We'll continue running a little below normal for max temps west of the mountains, and a little above normal in mountains and deserts this weekend. Monday should be cooler than normal for all areas, followed by a trend back toward normal, but not quite reaching it, Tuesday through Friday.
