NEXT RAIN CHANCE SAN DIEGO: UPDATED FRIDAY 2-16-2018

A potent cold front is headed this way late Sunday into Monday. This will bring a chance for showers Sunday night and through the day on Monday. It will also bring is some of the coldest air we've seen all winter. The first map below is Saturday, then the second map is Tuesday. You can see the cold air overspread the entire West Coast. Daytime highs in San Diego will stay in the 60s for most of next week. In addition, overnight lows will dip into the 40s.

Snow levels could dip to 3,000 to 4,000 feet Monday and Tuesday, however, the system will be somewhat moisture-starved, so snow will be limited.

This might be the start of a developing pattern, where cold fronts arrive in SoCal every few days. Definitely keep those jackets handy in the coming days!

NEXT RAIN CHANCE SAN DIEGO: UPDATED MONDAY 2-12-2018

Isolated showers will still be possible today and Tuesday. With the core of the system overhead, there is enough instability where we could also encounter a quick downpour, like the one this morning in downtown San Diego.

As expected, the computer forecasts are having difficulty with this system on Wednesday and Thursday. Latest data is showing a slight chance for showers on Wednesday. Then the chance for rain exits Wednesday night. At this point, I think this is a plausible scenario.

Another potent cold front is on the horizon. Temperatures will briefly rise on Friday and Saturday, then plunge into Monday. Some rainfall could also accompany this front. It's still far away, so there will still be some adjustments to the timing, path and strength of this system.
