Storm Tracker Forecast: Widespread showers & snow by Tuesday

Widespread showers and high elevation snow are in store for Tuesday. This will stay for Wednesday but become more scattered. Strong winds and cold weather will be in place with this system.

Posted: Nov 15, 2020 6:32 PM

We have had some strong fog over the last few days following the rain but fog shouldn't be too much of a concern going into tomorrow morning. Today we've seen a few showers in the northern mountains and coast as well, but dry conditions persist tomorrow. Mid-60s to mid-50s were prominent in the valley today with cooler temperatures farther north due to cloud cover and warmer temperatures farther south due to more sunshine.

Monday we'll get close to 70 degrees, give or take a few degrees, with partly cloudy skies. Winds remain light.

Big changes Tuesday. A large dip in the jet stream along with a cold front bring cooler temperatures and strong winds, especially in some mountain locations. Highs will remain in the mid-to-upper 50s in the valley Tuesday-Thursday.

A low pressure system makes landfall in Canada with a strong cold front swinging into NorCal. This brings widespread, steady rain to the valley and heavier rain totals in the foothills & mountains. Showers become more scattered on Wednesday. By Thursday only a few isolated showers are expected in mountain regions and the north valley. Rain totals could be anywhere from half an inch to an inch in the valley and 1 to 2 inches in the foothills, with locally higher totals in the mountains.

A WINTER STORM WATCH is in effect for elevations above 6,500 feet in the Sierra Nevada mountains where 6-14 inches of snow is possible. Some areas above 7,000 feet, such as Mt. Lassen, could see up to 2 feet of snow. Snow levels will start high at 6,500 feet Tuesday but could drop to 5,500 feet Tuesday night into Wednesday.

Friday will be breezy but partly cloudy and warmer with valley highs in the low-60s.

Saturday mostly sunny to sunny skies prevail with light winds.

Another weather system could bring more rain & snow to Northern California by SUnday at the earliest or Tuesday at the latest. Timing and strength of the following system are still hard to pinpoint.

A cold front has moved over northern California on this day before Thanksgiving, and it brought light rain and snow showers to the higher terrain, gusty wind and cooler air for all. Thanksgiving will still be breezy, but also mild and pleasant.
