Snow is always a big deal when we are talking about the lowlands of Western Washington. But, what we do know is that it’s going to be sunny and cold this weekend.

Showers will continue at times through Wednesday morning across the region. A rain and snow mix may occur as well during this period, particularly for areas of Lewis County and near the Cascade and Olympic Foothills.

Predictions for snow range from a trace to 8-10 inches, but we’ll have a much better idea on Thursday.

According to Nick Allard, 成人X站 7 meteorologist, “This air is going to be very dry and the overall atmosphere will not be rich with moisture during this transition, so we shouldn鈥檛 expect significant lowland snow potential on Thursday.”

He said some snow and wet snow showers are still possible early Thursday, however, the best bet for more consistent snow would be in a possible convergence zone over the North Sound and North Interior.

There could be some showers outside of that convergence as well, but there shouldn鈥檛 be much overall, even if some minor accumulation is possible.

Meteorologists disagree on what will happen on Friday. There鈥檚 a chance that major lowland snow will develop on Friday afternoon, according to Allard. An area of low pressure moves ashore Friday night into Saturday morning, with the potential to bring a mix of snow, sleet, or even freezing rain.

Several forecast models have that going farther south over Oregon, would limit impacts of snow to mainly the southern third of our area. A farther north track (as predicted by the U.S.-based GFS forecast model) has Western Washington being impacted by a major winter storm with some ice storm implications too.

Thurston County was getting a rain-snow mix on Wednesday morning and it’s accumulating.

Showers are going to decrease throughout the day on Wednesday.

鈥淭he bomb cyclone has pretty much passed through, so that鈥檚 almost history now,鈥 University of Washington (UW)聽atmospheric scientist聽听迟辞濒诲听Jason Rantz on AM 770 KTTH. 鈥淎nd when we talk about immediate logical bomb, we鈥檙e talking about a low-pressure system that revs up very quickly. There鈥檚 a fancy name in the literature called explosive cyclogenesis. Cyclogenesis means low development, so when it happens very quickly in this certain criteria, we call it a bomb. That鈥檚 all it is.鈥
