Posted: Jan 25, 2021 6:50 AM

The storm system that brought rain and snow to our region yesterday is starting to wrap up early today but very active weather is ahead in your forecast. We'll continue to see the potential for light to moderate rain in the valley today, and light to moderate snow in the Sierra and Cascades. An additional 2 to 4 inches of snow will be possible in our higher elevations to the east of the valley today. Modest rain amounts will be possible in the valley. A Winter Weather Advisory remains in effect through 9am in areas of the northern Sierra above 3000' through 9am this morning. Temperatures are in the 30's to 40's in the valley, 20's to mid 30's in the foothills, and in the 20's in most mountain areas to start your Monday. We'll have gusty north winds through the day. Sustained winds up to around 25mph will be possible, with gusts up to around 35mph. High temperatures will top out in the low to mid 50's in teh valley, in the upper 30's to mid 40's in the foothills, and in the 30's to 40's in our mountain areas this afternoon.

The break from the active weather will not last long. The next storm looks much more substantial than the previous two we've had, and will arrive to a much colder airmass. A Hard Freeze Warning has already been issued for the valley from 2am through 9am on Tuesday. Temperatures are projected to dip into the low to mid 20's, and could be in that range for up to 12 hours. Damage to outdoor crops and plumbing will be possible. You'll want to bring your pets indoors tonight. The next weather system is projected to arrive on Tuesday afternoon, and will continue to bring rain and snow into our forecast through Friday. Snowfall down into the valley looks very much possible from late Tuesday through early in the day on Wednesday. Winter Storm Warnings have already been issued for Siskiyou, Plumas, and Lassen Counties. Siskiyou County will be under the Winter Storm Warning from 1pm Tuesday through 4pm Wednesday, and from 7pm Tuesday through 4am Friday in Lassen and Plumas County areas. A Winter Storm Watch has been issued for Trinity County from Tuesday afternoon through noon Wednesday, from Tuesdya afternoon through 10am Wednesday in the valley areas of Tehama and Shasta Counties, in mountain areas of Shasta County from Tuesday afternoon through 4pm Thursday, and from Tuesday afternoon through 2am Friday for portions of the northern Sierra and Foothills. A couple inches of snowfall will be possible in the valley, 20inches of snow will be possible in Trinity County, up to 4 feet of snow will be possible in higher elevations in Shasta County, up to 3 feet of snow will be possible in our foothills, and up to 7 feet of snow will be possible in the northern Sierra above 4500'. This is going to be a major impact for mountain, foothill, and even valley travel during the times the Watches are active. We also have a High Wind Watch in effect from Tuesday night through noon Wednesday in the valley and foothills. Sustained winds out of the south to 35mph will be possible, and gusts up to 60mph are also possible during that time. Valley areas can expect upwards of 3 inches of rain this week, while some of our foothill and higher elevations may get more than 4 inches of rain. Temperatures will be dow in the 20's in the valley tonight, but overnight low tmeperatures will rebound back into the 30's to 40's for the rest of the week. High temperatures in the valley will be in the 40's on Tuesday, and then in the upper 40's to lower 50's for the remainder of this week. Snow levels will mostly dip to below 2000' this week, which means snow down into the foothills, but not expected in the valley after mid day Wednesday.

The latest models are keeping rain and snow in our forecast on Friday and Saturday, but it is not expected to be as substantial as Tuesday night through Thursday. Another impressive system is projected to move into northern California from Sunday through early next week. This will bring more impacts from heavy rain, heavy snow, and gusty south winds across northern California. We'll get a much better idea on the timing and strength of that system later this week, but at the moment it does look to arrive Sunday night and last through at least early next week.
