An "unsettled" weather system brought off-and-on showers with breaks of sunshine to most of the county Wednesday, and showers were expected to continue into Thursday.
NBC 7 Dagmar Midcap said the morning commute would be again be slick thanks to widespread, light showers starting at around 7 a.m.
Those widespread showers are expected to give way to pockets of moderate to heavy rain by noon before the skies clear just like they did on Wednesday, Midcap said.
Lake Cuyamaca and Palomar were at the top of the 24-hour rain totals at 7:30 p.m. with 1.6 inches and 1.09 inches, respectively. But coastal zones didn't see as much precipitation.
At higher elevations, like Mount Laguna, a light dusting of snow fell throughout the evening. You can watch snow fall outside of the Laguna Mountain Lodge on its live camera position right above its porch.
La Jolla, Mission Beach, the Tijuana Estuary and Del Mar each saw less than a tenth of an inch.
The storm was predicted to bring up to a quarter-inch of rain to San Diego's coastal areas with more significant amounts further inland over 48 hours, NBC 7 Meteorologist Sheena Parveen said.
The system moved in late Tuesday and brought spotty overnight showers across the county, making for a soggy commute for the early birds, NBC 7 Meteorologist Sheena Parveen said.
The brunt of the storm reached the county by Wednesday afternoon. Thunderstorms were a possibility but none were reported.
Meanwhile, the tops of Palomar Mountain and Mount Laguna could see up to two inches of snow, Parveen said.
The National weather Service issued a beach hazards statement through Wednesday night with waves and surf between 4 and 7 feet.
Parveen said Friday and Saturday will be much drier before another storm system moves into the region.
Frequent May showers are unusual for San Diego at this time of year of according to forecasters.
The rare systems are due to upper air patterns that allow for multiple cold fronts to sweep through the area with enough moisture and instability for continuous showers, the NWS said.
