Things were off to a foggy start in San Diego Tuesday as the first signs of a storm system moved into the region.
Dense fog was affecting parts of the South Bay overnight but began to creep to the inland valleys and central San Diego by sunrise, NBC 7 Meteorologist Sheena Parveen said.
Morning commuters could expect to see patches of fog on their drives but conditions were expected to clear at about 9 a.m.
Foggy conditions were a precursor for what San Diegans can expect for the rest of the week, Parveen said.
Clouds would be increasing Tuesday afternoon as the next weather system makes its way to the county.
Showers will begin to fall Wednesday morning with chances for rain extended through Thursday, Parveen said.
In total, no more than a half-inch of rain was expected.
Some snow may fall at mountain levels near 5,500 feet but less than an inch is expected.
Another bout of rain is possible on Saturday before a warm-up next week, Parveen said.
