San Diego residents can expect slightly cooler temperatures and a chance of rain as high temperatures have dipped from yesterday's peak, with some areas potentially missing their max temperature projections due to cloud cover and rainfall, according to NWS San Diego. In particular, the southeast portion of San Diego County, especially the Mt Laguna area, should be prepared for measurable precipitation today. Areas in the northern part of the county and southern Inland Empire (IE) also experienced showers this morning, although as moisture shifted southward, precipitation chances decreased.
Moving into Tuesday, the Coachella Valley and San Diego Deserts are advised to brace for a significant temperature uptick, with some areas hitting the upper 90s to low 100s. At the same time, rain chances will focus on the mountains, with a slight chance of afternoon and evening thunderstorms possibly affecting parts of Orange, Riverside, and San Bernardino counties, according to the National Weather Service reports. Moreover, the estimated rainfall amounts for today across the county vary. Still, most locations should see only light precipitation amounts of 0.01-0.1 inches, with slightly higher amounts anticipated over the northern county and the IE.
Regarding the forecast for the rest of the week, the NWS San Diego's Area Forecast Discussion indicates that widespread clouds and light showers will persist through the morning and shift south and east out of the area by early Monday afternoon. However, Tuesday afternoon through early Wednesday, we could see a return of rain and slight chances of thunderstorms, primarily north of San Diego County. The region should anticipate drier conditions starting Thursday, only for chances of precipitation to increase by Friday into Saturday. "By Sunday, the disturbance will begin to move east and out of the region, with slight warming and drying conditions going into the early part of next week," according to the forecast discussion.
