The next storm system is on our doorstep. It will bring isolated showers and drizzle tonight, then rain will overspread the area tomorrow afternoon and evening.
There is a moderate atmospheric river associated with this storm (first map), which will help transport moisture into our area. This should enhance the rain potential. The heaviest rain will move through the area Thursday night. Showers will then taper by early Friday afternoon.
I've included computer projections for rainfall below (second map). Coastal and inland areas will see 1-2" while the mountains will see 2-3".
Snow levels range from 9,000-10,000 feet tomorrow night into Friday morning. They will then drop to 6,000 to 7,000 feet Friday, so most local mountains won't see any snow. However, the highest peaks in San Bernardino and especially into the Sierra Nevada will see significant snowfall. I've included computer projected snow totals below (map 3).
The weather pattern will remain active with occasional showers and patchy drizzle popping up for the next several days, though it shouldn't amount to much. I'm still keeping a close eye on another bigger system that could arrive 12/28 to 12/30. This could bring more substantial rainfall and much cooler air (lower snow levels) to the area.
