“When we have a cold front moving in towards our area, what we get out ahead of the cold front are high clouds, and then as the cold front approaches and gets closer, you get lower and lower clouds — so you get what we call a lowering cloud deck,” Garcia said. “So with the sun coming up, obviously, the sun comes up over the horizon and it’s very low-angled, so it has the opportunity to shine light right through the slot and and give a little bit of elimination to the underside of the clouds.”
Locals took to social media to share their photos of the beautiful sunrise. Due to some rain that is moving through the Bay Area Friday, you might have even caught sight of a rainbow (or two).
“Any rain that’s present can generate a rainbow depending upon exactly where you’re at and how the light’s hitting it,” Garcia said. “… what happens with [double rainbows] is at very specific angles you can get your initial rainbow and then at a higher angle, you can actually get a double rainbow. It can happen anytime that you have a little bit of water in the air and the light passing through it [and] it’s just the right angle for where you’re at.”
The rain system for Friday was expected to start in the early afternoon, with the first droplets falling in the Sonoma County region at mid-day before moving southward through the Bay Area, hitting areas like San Mateo closer to 4 p.m., Garcia said.
The rain was to begin tapering off in the the North Bay by mid-evening, and wrapping up through the rest of the region by about 10 p.m. The Bay Area will also see more rain Sunday night going into Monday.
Expected rain totals for the first round of rain could be from 1 to 2 inches in the wettest parts of the Bay Area, such as Sonoma County; much of the Bay Area will see closer to .5 to 1 inch of rain; the South Bay is expected to see even less rain that that, with less than half an inch expected.
