Rain Threat to Give Way to Sunny Skies

Light rain will threaten today as clouds continue to shroud San Diego County skies, but the cheerless gray skies are expected to give way to sunny afternoons over the Mother’s Day weekend.

May is typically one of the cloudiest months of the year in San Diego, but this week’s weather pushed the amount of daily sunshine below average levels. According to forecaster Wilbur Shigehara, a low-pressure trough and upper-level winds brought in waves of clouds that by Thursday had formed three sun-blotting layers of low, middle and high clouds. Normally, the May clouds clear in the afternoon.

The low pressure system is scheduled to move east Saturday when average May weather is expected to bring back sunnier afternoons.

Beachgoing weather will improve slightly, but will continue cool--breezes from the west and southwest may blow to 20 knots, and coastal clouds may hug the shore until early afternoon. High temperatures in the 60s today are expected to inch into the 70s over the weekend. The ocean water temperature will hover at 63 degrees.

Clouds are expected to clear by mid-morning in inland areas Saturday and Sunday, with temperatures warming slowly through Sunday. Highs in the valleys should reach the low 70s by Sunday, with nighttime lows between 48 and 55 degrees. Lows at the coast will be slightly warmer--up to 61 degrees.

Forecasters said mountainous areas will be windy in unprotected areas, with west to northwest gusts up to 25 m.p.h. Highs are expected in the 55 to 65 degree range through Sunday with lows in the 38 to 48 degree range.

Desert temperatures that reached 100 at Borrego Springs Wednesday cooled with the full day of cloud cover Thursday, but were forecast to climb slowly to the 90s by Sunday. Lows are expected to be 62 to 68 degrees.
