A large area of low pressure is sitting and spinning up over the Pacific Northwest this week; it's there now. . .and as it sits and spins, it's creating an elongated area of low pressure, or low pressure "trough", along the West Coast. Even all the way here to San Diego!
What this low pressure trough will do for YOUR skies is to make them a bit cloudier. And cooler. The trough will keep the marine layer going for the next few days, and that means this afternoon there should be a little less sunshine at the coastline than there was yesterday. Also, this onshore flow will keep temperatures a few degrees cooler - meaning upper 60s at the beaches and mid 70s inland. Finally, the trough should deepen the marine layer to such a point this evening that some drizzle will be likely overnight tonight into Thursday morning. Not a lot of rain is on the way, but there could be some wet roads by the morning rush hour.
Looking ahead to the long holiday weekend, no major changes are on the way for San Diego. No "May Gray," no heat wave, no unusual rainstorm for this time of year - just more of the same. It hasn't been the most typical of May weather this year, but that's okay - it's GREAT weather and should be heading into the Memorial Day weekend.

There's never been a "clearer" weather forecast, that is, if you can get past the hair that's out of place. And sometimes the pattern on the tie. Did we mention the tie?
