Rain possible in San Diego County through Thursday

Weather Update: Wednesday, March 20, 2019 at 5:58 a.m.

Light and scattered rain Wednesday morning throughout the County. Rain may be heavier at times and chances persist through Thursday. Morning temperatures are warmer but afternoon highs will be below seasonal norms.

A Detailed Look at March 20th:

  • High rip current risk. Water temperature 59-61. Wave heights at 4'-6' becoming 5'-8' in the afternoon. Building west swell all day, underlying southwest swell. UV index for San Diego is high (6).
  • Wednesday afternoon high temperatures will be below seasonal norms. 
    • Coastal highs 62-65, normal around 66.
    • Inland highs 56-64, normal around 72.
    • Mountain highs 49-57, normal around 57.
    • Desert highs 70-75, normal around 79.
  • Fairly humid across most of San Diego County Wednesday. Dew point temperatures around 50 for the coast, upper 40s inland, upper 30s in the mountains and deserts. There is not expected to be much change in the dew points throughout the day due to an already established and lingering marine layer.
  • There are no reports of fog Wednesday morning. The marine layer has deepened as onshore flow becomes well established ahead of the storm. Skies will be mostly cloudy for most of San Diego County, especially west of the mountains. 
  • Rain will fall in San Diego County in the morning hours. Scattered thunderstorms possible, but most of the rain will be light or moderate and short-lived. Accumulations for Wednesday will be up to 0.15" for the coast and inland, up to 0.5" for some mountain locations. 
  • A High Surf Advisory is in place for San Diego County beaches from 1 PM Wednesday until 1 PM Friday. The Pacific storm will churn up waves during this period. Waves will increase Wednesday, peak Thursday, and subside on Friday. San Diego beaches may see waves 4'-8' and strong rip currents. 
  • Winds will be gusty for the desert with the passage of this storm system. Wind gusts of up to 45 mph are possible in the deserts, up to 15 mph gusts elsewhere. 

The Week Ahead:

  • Rain will continue through Thursday as additional energy and moisture pass through the region. Thursday rain will be mostly light to moderate and scattered in  nature. Models are suggesting that Thursday's rain will be more widespread in coverage, allowing more rain to fall on the County. There is a chance of heavier rain shower Thursday afternoon from thunderstorms. 
  • Friday will bring a break in the rain and some sunshine may return. A wave of low pressure passing to the north may push just enough energy over the region to see some light rain Saturday afternoon. Winds may pick up as the low pressure moves across the Great Basin. 
  • Weak high pressure will build over the Southwestern United States Sunday. Clouds will decrease with mostly sunny skies Sunday and warmer temperatures. Temperatures are expected to be above seasonal norms by Monday.
