prevailing wind direction map wyoming

Because of frequent spells of freezing weather before May 1 and after September 30, it is difficult to obtain consistent records of evaporation for more than the 5-month period from May through September. The average growing season (freeze-free period) for the principal agricultural areas is approximately 125 days. The weather pattern most favorable for precipitation is one with a low-pressure center a little to the south of the State. This is the wind, wave and weather forecast for Cheyenne Airport in Wyoming, United States. At lower elevations over the northeast portion and along the eastern border, where elevations are mostly in the range from 4,000 to 5,500 feet, annual averages are from 12 to 16 inches. However, records show that tornadoes which occur here are somewhat smaller and have a shorter duration. Use website settings to switch between units at any time. In the southern part of the Basin, Worland at 4,061 feet has an annual mean of 7 to 8 inches as compared with Termopolis at 4,313 feet and 11 to 12 inches. During this period the snowfall amounted to 39.0 inches, had a water equivalent of 4.30 inches and blizzard conditions lasted more than 43 hours. Many of the cold waves are not accompanied by enough snow to cause severe conditions. Snow is very light in the Big Horn Basin with annual averages from 15 to 20 inches over the lower portion and 30 to 40 inches on the sides of the Basin where elevations range from 5,000 to 6,000 feet. The season extends from April through September. The period of maximum precipitation occurs in the spring and early summer for most of the State. Usually there are less than 10 cold waves during a winter, and frequently less than half that number for most of the State. To view a list of wind research and development projects in Wyoming funded by the U.S. Department of Energy’s Wind Energy Technologies Office, visit the Wind R&D Projects Map and select Wyoming … The lower portion of the Basin has an annual precipitation of 5 to 8 inches, and it is the driest part of the State. There are usually several local storms each year with from 1 to 2 inches of rain in a 24-hour period. The overall range is from 30 to about 50 inches. Click on the link for ‘Wind Rose Plots.’ Next, select your state, then select the .gif file for the location and month(s) of the year you are interested in. For hardier plants which can stand a temperature of 28° F, or slightly lower, the growing season is the agricultural areas east of the Divide is approximately 145 days. Many of them touch the ground for only a few minutes before receding into the clouds. Wyoming is quite windy, and during the winter there are frequent periods when the wind reaches 30 to 40 miles per hour with gusts to 50 or 60. Tornadoes occur, but records show they are much less frequent and destructive than those that occur in the Midwest. Forecasts are available worldwide. Because of its elevation, Wyoming has a relatively cool climate. Because the altitude provides less atmosphere for the sun's rays to penetrate and because of the very small amount of fog, haze, and smoke, the intensity of sunshine in unusually high. There is no drainage from this Basin and precipitation, which averages only 7 to 10 inches annually, follows creekbeds to ponds or small lakes where it either evaporates or percolates into the ground. This site is a tool to provide information about wind energy, Wyoming's wind energy potential and associated industry, and a source for news and updates. The majority of cold waves move southward on the east side of the Divide. For the places like the Star Valley and Jackson Hole, the growing season is even shorter. About five times a year on the average, stations at the lower elevations will have snowfall exceeding 5 inches. The mountains receive a great deal more and in the higher ranges annual amounts are well over 200 inches. For converting between wind speed units such as knots, km/h (kilometers per hour), m/s (meters per second), and mph (miles per hour), you can use our wind speed calculator. The prevailing wind in a region of the Earth's surface is a surface wind that blows predominantly from a particular direction. Hailstorms are the most destructive type of local storm for this State, and every year damage to crops and property from hail amount to many thousands of dollars. The record low for the State is -66° F observed February 9, 1933, at Yellowstone Park. Like other states in the west, precipitation varies a great deal from one location to another. For most places away from the mountains, the mean minimum temperature in July ranges from 50 to 60 ° F. Of course, the mountains and high valleys are much cooler with average lows in the middle of the summer in the 30s and 40s with occasional drops below freezing. This results in long winters and short growing seasons. Units Forecasts are computed 4 times a day, at about 11:00 PM, 5:00 AM, 11:00 AM and 5:00 PM Mountain Daylight Time. Since the mountain ranges lie in a general north-south direction, they are perpendicular to the prevailing westerlies, therefore, the mountain ranges provide effective barriers which force the air currents moving in from the Pacific Ocean to rise and drop much of their moisture along the western slopes. Current Wind Direction Forecast map for Wyoming. There is a relatively small area along the southwest border that is drained by the Bear which flows into the Great Salt Lake. Early freezes in the fall and late in the spring are characteristic. Protecting mountain ranges prevent the wind from stirring the air, and the colder heavier air settles into the valleys often sending readings well below zero. The relatively small amount of destruction is partly due to the fact that most of Wyoming is open range country and sparsely populated. During the summer, showers are quite frequent but often amount to only a few hundredths of an inch. Wyoming's outstanding features are its majestic mountains and high plains. Only a few locations receive as much as 40 inches a year, based on gage records. We use knots and degrees Celsius as our default units. Part of this area is often referred to as the Red Desert. Weather radar, wind and waves forecast for kiters, surfers, paragliders, pilots, sailors and anyone else. At Beckler River Ranger Station in the southwest corner of Yellowstone Park, the snowfall averages 262 inches for a 20-year period. The Continental Divide splits the State from near the northwest corner to the center of the southern border. The highest recorded temperature was 114° F on July 12, 1900, at Basin in the Big Horn Basin. There is another good example in the southeastern part of the State where Laramie at 7,236 feet has an annual mean of 10 inches, while 30 miles to the west, Centennial at 8,074 feet receives about 16 inches. There are several mountain ranges, but the mountains themselves cover less area than the high plains. The station showing the least amount is Seaver at 4,105 feet with an annual mean of about 5.50 inches. For tender plants there is practically no growing season in such areas as the upper Green River Valley, the Star Valley and Jackson Hole. The State is considered semiarid east of the mountains. An unusually heavy snow occurred at Sheridan on the 3rd and 4th of April 1955. At the lower elevations in the east, the range is from 60 to 70 inches. A smaller percentage of time the State is covered by cold air masses that move down from Canada. The greatest 24-hour total recorded for any place in Wyoming is 5.50 inches at Dull Center, near Newcastle, on May 31, 1927. June has the greatest number on the average with May next and most occur in the eastern part of the State. The topography and variations in elevation make it difficult to divide the State into homogeneous, climatological areas. In the mountains and high valleys freezing temperatures may occur any time during the summer. Look at our spot map to find more spots like this among our 45000 spots. Prevailing directions in the different localities vary form west-south-west through west to northwest. For most of the State, sunshine ranges from 60 percent of the possible amount during the winter to about 75 percent during the summer. In many localities winds are so strong and constant from those directions that trees show a definite lean towards the east or southeast. The Forecast is based on the GFS model. Mountain areas receive less, and in the wintertime the estimated amount over the northwestern mountains is about 45 percent. In the wintertime it is characteristic to have rapid and frequent changes between mild and cold spells. Worldwide animated weather map, with easy to use layers and precise spot forecast. The relatively dry southwest portion is a high plateau nearly surrounded by mountain ranges. This leaves most of the drainage areas to the east. The run-off drains into three great river systems: the Columbia, the Colorado, and the Missouri. A few places in the mountains at about the 9,000 foot level have average maximums in July close to 70° F. Summer nights are almost invariably cool, even though daytime readings may be quite high at times. Mean January temperatures in the Big Horn Basin show the variation between readings in the lower part of the valley and those higher up. High winds and low temperatures with snow cause blizzard or near blizzard conditions. At Worland and Basin in the lower portion of the Big Horn Basin, not far from the 4,000 foot level, the mean minimum temperature for January is zero, while Cody, close to 5,000 feet on the west side of the valley has a mean January minimum of 11° F. January, the coldest month, has occasional mild periods when maximum readings will reach the 50s; however, winters are usually long and cold. The arrows point in the direction that the wind is blowing. Sometimes only the northeast part of the State is affected by the cold air as it slides eastward over the plains. Forecast models ECMWF, GFS, NAM and NEMS These units are often used by sailors, kiters, surfers, windsurfers and paragliders. Forecasts are available worldwide.
