NEXT RAIN CHANCE SAN DIEGO: UPDATED SUNDAY 1-20-2019

Clouds have moved into our area today as a storm system approaches from the north (seen on the satellite loop below). This system will push a front through Southern California tonight and bring us a brief chance for a couple showers. It will also bring cooler air, so get ready for some chilly nights!

Afterward, a blocking pattern will develop in the Pacific (indicated by the red blob in the second map below). This will prevent any storm systems from moving into the West Coast. Long range computer forecasts are hinting at an erosion of this pattern by the first week of February (seen on the third map below). I'll be keeping an eye on this and will bring updates in the coming days.
