what is the weather like in washington state in november
Some of the greatest seasonal snowfalls and snow depths in the United States have been recorded on the slopes of Mt. Hotel in or out of town? The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The percent of possible sunshine received each month is from 20 t 30 percent in winter, 50 to 60 percent in spring and fall and 80 to 85 percent in summer. The number of hours of sunshine possible on a clear day ranges from approximately eight in December to 16 in June. In the driest areas, rainfall is recorded on 70 days each year and on days or more in the higher elevations near the eastern border and along the eastern slope of the Cascades.

Annual precipitation ranges from seven to nine inches near the confluence of the Snake and Columbia Rivers, 15 to 30 inches along the eastern border and 75 to 90 inches near the summit of the Cascade Mountains. During July and August, it is not unusual for four to eight weeks to pass with only a few scattered showers.

Thunderstorms can be expected on one to three days each month from April through September. Most thunderstorms in the warmest months occur as isolated cells covering only a few square miles.

Seattle, WA

A few damaging hailstorms are reported each summer. Maximum rainfall intensities to expect in one out of ten years are. During the coldest months, a loss of heat by radiation at night and moist air crossing the Cascades and mixing with the colder air in the inland basin results in cloudiness, for and occasional freezing drizzle.

Frost penetration in the soil depends to some extent on the vegetative cover, snow cover and the duration of low temperatures. In an average winter, frost in the soil can be expected to reach a depth of 10 to 20 inches.

During a few of the colder winters with little or now snow cover, frost has reached a depth of 25 to 35 inches. During most of the year, the prevailing direction of the wind is from the southwest or west. The frequency of northeasterly winds is greatest in the fall and winter. Wind velocities ranging from four to 12 m. The highest wind velocities are from the southwest or west and are frequently associated with rapidly moving weather systems. Extreme wind velocities at 30 feet above the ground can be expected to reach 50 m. During the growing season, April through September, the average evaporation from a Class A evaporation pan is from 35 to 52 inches.

Monthly evaporation is midsummer ranges from nine to 12 inches. Annual evaporation from lakes and reservoirs is estimated at 26 inches in the mountains and 34 to 42 inches in other localities.

The average relative humidity in January is approximately 85 percent at 4 a. In order to describe the climate in more detail, eastern Washington has been divided into five sections: In an easterly direction, the elevation decreases from the summit of the Cascade Range to approximately 2, feet above sea level.

One of the outstanding features of the climate is the decrease in precipitation along the eastern slope of the mountains as the distance from the summit increases and the elevation decreases. For example, within a distance of 20 miles, the average annual precipitation decreases from 92 inches at Stampede pass elevation 3, ft. The average winter season snowfall decreases from approximately inches near the summit of the mountains to about 75 inches at 2, feet above sea level.

How is the weather in Washington, DC in November?

In elevations above 3, feet snow can be expected in October; however, it generally does not accumulate on the ground until after the first of November.

In the lower elevations snow reaches a depth of two to five feet in January or February and in the higher elevations, 10 to 20 feet by the first of march.

The density of the snow pack increases from approximately 30 percent water at the beginning of the winter season to 45 percent water by mid-march. In the higher elevations, snow remains on the ground until June or July. Several large irrigation reservoirs are located in valleys along the eastern slope of the Cascades.

Melting of the snow provides irrigation water for orchards and other agricultural areas in the Okanogan, Wenatchee, Methow, Yakima and Columbia River valleys. A cool mountain breeze in the late afternoon results in rapid cooling after sunset.

The elevation varies from approximately 1, feet in the lower river valleys to 3, feet over the Waterville Plateau and Okanogan highlands. North-south ranges of mountains extending into southern British Columbia reach elevations of 4, to 5, feet within a few miles of the Okanogan River.

The annual precipitation increases from 11 inches in the valley to 16 inches over some of the Plateau. Winter season snowfall varies from 30 to 70 inches. Both rainfall and snowfall increase in the higher elevations.

Washington State Weather

Snow can be expected after the first of November and to remain on the ground from the first of December until March or April.

Snow accumulates to a depth of 10 to 20 inches in the valleys and over the Waterville Plateau, increasing to 40 inches in the higher grazing areas. Occasional outbreaks of cold air from Canada moving southward though the valleys result in a late spring or early fall freeze. Thunderstorms occur on 10 to 15 days each summer, and a few damaging hailstorms are reported in the fruit-producing valleys.

Yakima, WA

The average date of the last freezing temperature in the spring is the latter half of April in the warmer fruit-producing valleys along the Columbia and Okanogan Rivers, the middle of may in the colder valleys along the Wenatchee and Methow Rivers and the last of may over the Waterville Plateau and the higher rangelands. The first freezing temperature in the fall usually occurs in the latter half of September on the Waterville Plateau and by the middle of October in the warmer fruit-producing valleys.

Average Temperatures for Washington in November

The elevation increases from approximately feet at the confluence of the Snake and Columbia Rivers to 1, feet near the Waterville Plateau and 1, feet along the eastern edge of the area. This is the lowest and driest section in eastern Washington. Annual precipitation ranges from seven inches in the drier localities along the southern slopes of the Saddle Mountains, Frenchman Hills and east of Rattlesnake Mountains, to 15 inches in the vicinity of the Blue Mountains.

Summer precipitation is usually associated with thunderstorms. During July and August, it is not unusual for four to six weeks to pass without measurable rainfall.

The winter season snowfall is from 10 to 35 inches. Snow can be expected after the first of December and to remain on the ground for periods varying from a few days to two months between mid-December and the last of February. Other than in the Ellensburg valley, snow depths seldom exceed eight to 15 inches. A few damaging hailstorms are reported in the agricultural areas each summer. The last freezing temperature n the spring occurs during the latter half of April in the Yakima valley and the latter half of may in the colder localities of the Columbia Basin.

The first freezing temperature in the fall is usually recorded between mid-September and mid-October. Ranges of mountains in this section of the State are separated by narrow north-south valleys. The elevation increases from 2, feet in the valleys to 6, feet along the higher ridges.

It is likely to be cold, but not bitterly cold. But we have also had a major snowstorm as early as November 11, so who knows. It will be what it will be. November might be reasonably pleasant and sunny.

Or it could snow. Pretty unlikely, but it's happened. So it might be rainy, cloudy, damp.

Or cold but sunny. It's not likely to be warm. I grew up in the area pushing 50 years old. November is when we more often get hit with cold, rainy weather. Snow is rare, and if it happens, it doesn't stick. BUT it seems to throw everyone into a panic. We are arriving on Dec. As you can probably deduce from the previous answers, there is no way to predict the actual weather so far in advance. This section discusses the wide-area hourly average wind vector speed and direction at 10 meters above the ground.

The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages. The average hourly wind speed in Tacoma is essentially constant during November, remaining within 0.
