The Northwest could see a year's worth of snow this weekend

Portland snow

The National Weather Service said snow and ice are possible early Friday, but then a brief break in precipitation of all types is expected for much of the day before the next, stronger, system arrives overnight. Temperatures will only warm up to the upper 20s and lower 30s, so it will be cold enough for the frozen precipitation. The daytime high will be about 31 degrees.

For some historic context, Seattle would need a little over 7 inches of snow on Friday to place it in the top 10 snowiest single days on record.

While piercing wind gusts are to be expected in these higher elevations, cities such as Portland and Seattle will be fanned by 25 to 40 miles per hour gusts during the passing of these storms, bringing wind chills in the respective cities down to the teens at times.

Freezing rain is increasing across the area, and will turn steadier this morning into this afternoon.

"February in Alabama is really a trying time in regards to weather", the weather service said in one of its forecast discussions on Friday morning. Sunday's high is near 34, dipping to around 29 into Monday morning, with an additional sleet accumulation of less than a half-inch possible during the day Sunday and light or no accumulation expected Sunday night.

The winter storm continues Saturday with chances of snow before about 4 p.m. The weather service says up 12 inches (30 centimeters) of snow are possible in the White Mountains. Forecasters aren't expecting much more than an inch or 2 across interior MA, with mainly an inch or less predicted elsewhere. The main factor will be the influence of cold air coming from the gorge.

"A significant winter storm is expected to impact the entire Four State region with a mix of snow, sleet, and freezing rain Sunday night into Monday".

The final act of the three storms is forecast to be served up late Sunday into Monday.

These totals are dwarfed by the forecast totals across the higher elevations of the Cascades in Washington and northern Oregon.
