(Portland, Oregon) – There are numerous weather situations popping up throughout much of Washington and Oregon, with the first real snow of the season for the entire Cascades, valley towns will see the first frost of the year and there may be some funnel clouds later in the week.

The National Weather Service (NWS) said there won't be any snow in the Oregon Coast Range, but the coastline and the valley may see some thunderstorms.

NWS even issued some weather advisories.

From Tuesday afternoon through early evening Wednesday, there is a winter weather advisory for the Cascades, all the way from southern Washington through much of southern Oregon. As much as two inches of snow is expected above 3,000 feet, while six inches could pile up in higher elevations.

Mountain ski resorts in Oregon will be getting a good dusting, with as much as a foot of snow above 4500 feet.

“Locations from Mt. Jefferson southward along the Cascade crests as well as any other locations at elevations above 6000 ft are forecast to receive the most snowfall from this system,” the NWS said.

The Oregon Coast Range won't be problematic at all, but the Cascades will be another story for motorists.

“If you have plans in the Cascades between Tue-Wed, prepare for winter weather conditions,” the NWS said. “If traveling, winterize your vehicle, pack an emergency supply kit, share travel plans with friends/family, and check road conditions at tripcheck.com (OR) or wsdot.com (WA).”

There may, however, be some traces of snow in the highest areas of the coast range.

In the Willamette Valley, Portland and even the Oregon Coast Range, expect frost to happen overnight on Friday after midnight – at least in some areas. Overnight lows are expected around 33 or 32 for the first time, happening on Friday and through the weekend.

Then there's the possibility of some wild sights.

“There is a slight chance (15-25%) for thunderstorms across the coast and Willamette Valley Tuesday to Wednesday,” the NWS said. “There is a small, but non-zero chance that some storms may produce a funnel cloud or a weak tornado.”

Meanwhile, seas along the Oregon coast will remain calm this week, after a small craft advisory for Tuesday subsides.
