NEXT RAIN CHANCE SAN DIEGO: UPDATED 10 PM FRI 1-22-2016

An upper level storm system currently spinning off the Pacific NW Coast (seen on the water vapor loop below) will tap into some energy/moisture from the south. This will bring us cloudy skies on Saturday. We also have a chance for an isolated shower from 4 PM to 10 PM (30%).

I'm keeping an eye on a potential shift in the weather pattern for the end of the month. Most of next week looks dry and warm (second map). Most computer forecasts are then hinting at a storm system and cooler weather around Sunday 1/31 (third map). This is still far into the future, so a lot can change. I'll monitor it and bring more updates.

This next map shows the percentage of normal precipitation, which helps to spot which areas were abnormally dry. You can see that most of the state was hurting for rain. Although rainfall was slightly below normal in San Diego, most of California was much below normal. However, in regards to rainfall (or lack thereof) no records were broken this year  The next two maps show temperatures across the entire country. The first is the departure from normal, while the second shows the rankings since 1895. The next two maps show precipitation across the country.
