Happy St. Patrick’s Day!
A quick-moving storm moved out of the area early Monday morning. This system dropped up to an inch of rain along the coast and valleys and up to a half an inch in Northern California. Snow levels dropped down to 3,000′ in the Cascades and areas above 4,500′ saw snow accumulation anywhere from 3″ to 7.” After 5 a.m., the precipitation associated with this storm fizzled out and only isolated shower activity remained.
High pressure will build back in after this storm. This means the trend of dry, partly cloudy weather will return. Behind the cold front that came with this system, a cold pool of air has entered the area. This will keep temperatures several degrees cooler during the week. Since yesterday, high temperatures are already 20+ degrees cooler in the valleys, mountains, and basin. Highs yesterday were in the mid 70′s. Today, highs got up to the mid 50′s. This trend will last throughout the week. Temperatures will now be closer to seasonal average.
On the first day of Spring, a weak disturbance will enter, north of the area. This will increase cloud coverage and bring a slight chance for light isolated shower activity. Any rain that will fall with this system will be in the northern regions of our area. Northern California will just get an increase in clouds. After this passes, sunny and warm weather is on tap for the weekend.
Thanks for logging on and have a great St. Patrick’s Day!
