Rare Cold Storm Still on Track, with Some Small Changes

Feb 24, 2011; 2:39 PM ET

I do not have a lot of changes to the long posting of yesterday for the weather from Thursday night through Friday in California. You can check the original post by clicking here.

But there are some changes, especially for Southern California. The cold front dropping south late tomorrow and tomorrow night will have more southwest flow ahead of it than was forecast yesterday. This will probably push up snow levels ahead of that front tomorrow night. They are likely to climb to 4,500 feet or so on south-facing slopes, while on north-facing slopes the snow could fall at levels from 500 to 1,000 feet lower. Those snow levels will start to fall again late tomorrow night and Saturday morning, reaching the levels I talked about yesterday by Saturday midday and afternoon. Rain ahead of the front is also looking to be pretty heavy for a time, mainly later tomorrow night around Los Angeles, and very late tomorrow night through midday Saturday in San Diego.

Snow levels could also be somewhat higher tomorrow afternoon and early tomorrow night in central California before the front passes, perhaps 3,500 to 4,000 feet, but will fall late down to 2,000 feet by Saturday morning.

Continue to expect travel problems over the Coastal Range passes, in any of the higher hills and mountains around the Bay Area on north, in the Upper Deserts of Southern California, and through all the passes leading out of the Los Angeles basin. Travel problems are a given in all of the Sierra and Southern California mountains as well.

If you are planning on travel in these areas, be prepared and check ahead of time for any updates from local authorities on road conditions.
