SAN DIEGO WEATHER UPDATE: 1:00 PM WED 12/24/2014

A powerful cold front will pass the area tonight and bring a brief chance of rain to San Diego. As I talked about in my previous blog past, the brunt of this system will miss us to the east. In addition, there is very limited moisture. Regardless, there will be *just* enough instability in the atmosphere to support convection.

Bottom line: there is a chance for showers and/or isolated downpours from 9 PM tonight to 6 AM tomorrow.

Another shot of cold air arrives Tuesday 12/30. This will keep high temperatures in 60s and lows in the 40s for the next several days. I'm still keeping an eye on a potential pattern shift around 1/4 to 1/8. It could bring milder temperatures, though rain chances are uncertain at this time.
