Synopsis
A strong winter storm will continue to impact the region today into Sunday with heavy snow above 1000 to 1500 feet and small hail at lower elevations. Another storm will bring additional precipitation Monday into Tuesday with snow levels rising back above 3000 feet.

Widespread shower activity is ongoing across Northwest California this morning with numerous reports of hail and snow covered roadways across the region. Snow levels have lowered significantly, now to near 1000 feet or even 500 feet in some areas. Temperatures have fallen in many valley and coastal areas into the mid to upper 30s and may fall a few more degrees before sunrise. Heavy snow is causing widespread impacts on area highways, particularly on highways 199, 299, 3, and 36. Snow has been reported from near Garberville to Laytonville. It is difficult to tell if any snow is falling at Ridgewood Grade between Willits and Ukiah at this time, but temperatures definitely would support the possibility.

Essentially, at this time the forecast is on track with heavy snow impacts expected to continue through the day into tomorrow at elevations over 1000-1500 feet, lowest in the interior and north, while small hail showers impact areas below these elevations. This will make travel treacherous for the next 24-36 hours and possibly further into Sunday night and Monday morning. Anyone thinking of traveling this weekend should be prepared for snow/icy roadways and much slower travel. Some of the higher highway passes may be completely closed at times. And it wouldn't be a shock to see some snowflakes at the coast early this morning or Sunday morning.

The one hazard that does seem to be coming to an end this morning will be the gusty winds as the cold core of the airmass settles over Northwest California. It won't be until Monday when the next chance for strong winds return with another approaching system. This system will also bring rising snow levels, back to over 3000 feet by Monday afternoon, reducing the travel impacts despite an anticipated increase in precipitation intensity into Tuesday. The model trend has continued toward another low pressure system approaching the area Monday night bringing widespread stratiform precipitation to the area into Tuesday. 24-hour rainfall could range from 1-3 inches across the area, most likely heaviest in the northern portions of the forecast area, which will be notable but not currently anticipated to be highly impactful even with any snow melt included. For instance, the river forecast center's ensemble forecast doesn't have a single member approaching monitor stage on the Smith River throughout the next 10 days.

There is hope for a dry day or a two beyond Wednesday but the Climate Prediction Center continues to indicate above normal precipitation chances in their 6-10 and 8-14 day outlooks for our region. /RPA

Marine
WSW winds weaken and trend westerly today, but remain blustery through Sunday. Showers and convection will continue into Sunday, bringing gusty winds, isolated thunder, small hail, and isolated waterspouts. A large, fresh W swell currently reading around 16 ft at 14 seconds is expected to persist this morning then is forecast to quickly decay this evening. Shorter period W waves quickly filter out this morning as the local winds weaken. Seas continue to trend down through the first half of next week, but are expected to remain above 10 ft through Sunday night. Another frontal passage is expected Monday, bringing another round of southerlies.
