The active weather pattern over the Northwest brought another storm to the region to end the week. A fresh batch of rain and snow is expected, with forecasters monitoring the potential for snow in the Seattle area.The storm system that has been spinning over the Gulf of Alaska over the past couple of days began to move toward the coast of British Columbia on Thursday. This brought a cold front to northwestern Washington, which spread areas of rain and mountain snow to the area.This front began to push south on Friday, spreading rain along the coasts of southern Washington, Oregon and far Northern California. As spotty rain showers spread farther inland, snow began falling in the higher elevations of the Washington Cascades. Snow then mixed with rain in parts of the Oregon Cascades on Friday afternoon.Precipitation will continue to spread into western Montana as well as northern Nevada and Utah through Friday night and Saturday.While this storm may carry more moisture than previous storms, it will still lack enough to bring more than isolated rain showers to the interior valleys.CLICK HERE FOR THE FREE ACCUWEATHER APPPeriods of rain will dampen coastal areas, including Seattle as well as Portland and Eugene, Oregon.Since the beginning of this year, Seattle has recorded 13.47 inches of rain in this stormy pattern. Normal rainfall from January through the month of March is 12.91 inches.In areas of Northern California, this storm can bring the first measurable rainfall since late January. Redding, California, last measured 0.02 of an inch of rain on Jan. 28. In January, 2.83 inches of rain fell in this city; the normal rainfall from January through March is 16.02 inches.Rainfall from this storm could reach up to half of an inch across the Northwest and into Northern California, but in areas that receive the heaviest showers rainfall totals may climb closer to an inch. Northern and western facing mountain slopes would be most likely to record these higher totals.Much of Northern California is under moderate drought conditions, while others are considered abnormally dry, according to the U.S. Drought Monitor.Cold air moving in behind the storm will help snow fall across the lower elevations. By Friday night, snow levels in the Cascades are expected to drop to around 1,000-2,000 feet.Snow levels this low could allow wet snowflakes to mix in with rain as in the hills around Seattle.The city has received less than an inch of snow so far this winter.This would bring accumulating snow to pass levels including Snoqualmie Pass, Stampede Pass and Barlow Pass. Travelers should be cautious of slippery and snow-covered roads into the mountains and be aware of tire chain regulations.Snowfall totals can reach 3-6 inches in the Cascades into the weekend with an AccuWeather Local StormMax™ of 12 inches possible in the highest peaks in the northern part of the mountain range. In addition, gusty winds of 20-30 mph will be quite common, especially along the coasts and into the mountains.The storm will continue to push inland over the northern Plains and into south-central Canada to end the weekend.Next week, forecasters will switch their focus farther south as a storm is anticipated to spread rain into the region while a break in the stormy pattern settles over the northwestern United States.Keep checking back on AccuWeather.com and stay tuned to the AccuWeather Network on DirecTV, Frontier and Verizon Fios.
