It didn’t snow in the Puget Sound lowlands in February. Nor did significant numbers of flakes accumulate in November, December or January. And with relatively mild weather on the horizon for the first week of March, it appears the region has dodged the white stuff entirely this winter, said University of Washington meteorologist Cliff Mass.

“Once you get past that first week in March, the chance of getting any significant snow in the lowlands drops to virtually zero,” Mass said Friday. Only rarely in the past has the region seen even light snowfall that late in the year, he added.

February also was unusually dry, said Jay Neher, of the National Weather Service. At 1.58 inches, precipitation at Seattle-Tacoma International Airport was almost a full 2 inches below normal for the month.

A warm front that rolled into the region Thursday evening will remain in force through about midday Saturday, Mass said. High temperatures will be in the low to mid-50s and freezing levels will hover at around 5,000 feet.

This week, save 90% on digital access.

By Saturday afternoon, though, a strong cold front will move in, bringing cooler temperatures, heavy lowland rain and snow above 2,000 feet. Low temperatures in the Seattle area are predicted to drop to 40 degrees or lower Saturday night.

The heaviest rain will sweep through fairly quickly. By Sunday, the chance of rain in Seattle drops to 30 percent.

Monday looks positively springlike, Neher said. “Mostly sunny, with a high of about 50.”
