High pressure off the coast in the Eastern Pacific is keeping northern California warm and dry today. That ridge will cotninue to be the main driving factor in your forecast on Saturday, but more clouds are expected to sag into our region by Saturday afternoon. Temperatures topped out in the mid 60's for most of the valley today, while mountain and foothill areas mostly saw mid 50's to low 60's this afternoon. Winds have mostly been under 10mph out of the Northwest. Similar weather will cotinue as we head into your Saturday but more clouds are expected to drop into our region through the day. A cool and wet system is projected to pass through to our North late Saturday into early Sunday. The biggest change to your forecast will be a modest drop in temperatures, but we will also have the potential for light showers brushing through higher elevations. There will also be a very slight chance for a light shower in dip into the northern end of the valley, but that's looking less likely in the latest model runs. The best chance for mountain showers will start late Saturday evening and last through early in the day on Sunday. Snow levels will be down to around 6000' and we are not expecting much in the way of accumulation. Rain totals where we do actually see rainfall will be up to around a tenth of an inch. Temperatures will continue to be above average through your weekend despite the cooler system passing through.
The low pressure trough that brings the modest cooling trend and chance for mountain showers will move off to our East for the start of next week. Gusty north winds will develop in the wake of that trough early next week. Gusts up to around 35mph out of the north will be possible in the valley, and stronger gusts can be expected in Sierra and foothill locations on Monday and Tuesday. There will be a slight chance for gusty winds continuing on Wednesday. Temperatures will climb back into the mid to high 60's in the valley from the middle to latter part of next week, and higher elevations can expect high temperatures in the 50's to low 60's. Long range models are currently hinting at a chance for a wet system bringing showers back to northern California next weekend, but a lot could change over the next week.
