On Monday, will there be a little snow on the ground when you get up? Depending on where you are, it might.
A cold upper level trough is located offshore of the Pacific Northwest, according to the National Weather Service, and it is expected to bring lowland precipitation that is a combination of rain and snow throughout the morning.
At approximately five in the morning on Monday, traffic cams revealed snow showers occurring in McMinnville, as well as snow on the ground at Gales Creek close to Banks and along the Coast Range. Additionally, Tillamook, Clatsop, and other coastal counties are under a winter weather advisory through Monday at 10 a.m.
Some rural counties have postponed their opening times or placed buses on snow routes. Visit OregonLive.com/weather/school-closings to check yours.
Given that most valley locations have a 30–50% probability of seeing snowflakes, particularly in the morning, Portland may see rain showers mixed with snow on Monday. Snow will give way to rain around noon as the temperature rises to around 42 degrees.
As the snow level drops to around 300 feet, overnight snow showers are possible. However, little precipitation is anticipated.
Overall, according to the weather service, Tuesday and the rest of the week will see lower temperatures, which will allow for greater snowfall and longer periods of sticking snow.
There is a risk of snow showers in Portland on Tuesday morning through lunch, followed by rain and snow in the afternoon. The temperature will rise to approximately 41 degrees.
With cooler temperatures brought on by an easterly flow, a front is predicted to move into the area on Wednesday morning, bringing fresh snow to the Coast Range, the foothills, and the Cascades. On Wednesday, there is a greater chance of lowland snow than there was earlier in the week.
Although models are uncertain, current projections indicate that snow accumulation in different valley sites will range from a quarter to three-quarters of an inch through Wednesday night. In the lowlands of southwest Washington and the Willamette Valley, there is a 20–50% possibility that valley snow levels will be at least one inch, according to some models.
Early on Wednesday, Portland should primarily see snow showers, particularly in the higher altitudes of the West Hills and the about 1,000-foot-high Mount Scott. About 39 degrees will be the high temperature. In the afternoon, there is a chance of snow and rain.
Cold weather is expected to persist through Thursday, Friday, and into the weekend, according to extended forecasts. At least through Friday, daytime highs are probably going to remain in the mid 30s or low 40s. No significant snowfall is anticipated as the precipitation will continue to move through in showers.
Snowfall is predicted to be widespread through Wednesday. These pictures show the likelihood of particular levels of snow accumulation as well as the anticipated accumulations through Wednesday.q5Jucld888 #wawx#orwxpic.twitter.com
