Possible snow showers expected to diminish this morning might be a prelude to a major snowstorm later this week, the National Weather Service in Seattle said.
Up to an inch of snow could fall in the Tacoma area, according to the weather service, but most local areas are likely to get little or no accumulation.
Any snow showers are expected to diminish by this morning as the weather turns cool and dry Monday and Tuesday.
Then things could get really interesting.
Never miss a local story.
It’s still very early, but the weather service says an approaching storm system could generate from between a couple of inches to more than foot of snow.
“There’s endless scenarios depending on where you live,” said Dennis D’Amico, a meteorologist for the weather service. “We are getting the word out about the potential for winter weather.”
It could be the most significant snow so far this winter, he said, and it could rival the snowstorm that socked the region in December 2008.
“Yes, it has the potential to do something like that or more,” D’Amico said.
The weather service issued a weather statement for the region that noted the potential for heavy accumulations but noted that “great uncertainty inherently exists in a forecast with this much lead time and it is possible that a heavy snow situation will not develop.”
D’Amico said residents should use this opportunity to start thinking ahead and preparing in the event winter weather arrives.
Cliff Mass, a professor of atmospheric sciences at the University of Washington, wrote on his blog that there’s the potential for a major snowstorm, but there’s uncertainty about how the system will develop.
“The weather will crucially depend on the position of the low (pressure system); if it goes north of us we get rain, just south of us, a big snowstorm, too far south, nothing. We need to wait to really know what is going to happen.”
