Climate Summaries Submit Storm Report, Social Media 28.9F and 37.0F respectively. PO Box 168 The snowfall totals are annual averages based on weather data collected from 1991 to 2020 for the US National Centers for Environmental Information. Climate scientists warned the Guardian early this month that preliminary data from NOAA showed the average temperature at the ocean's surface had been at 21.1C since the start of April . The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory. During the winter season, the state experiences frequent and rapid changes in the coldness level, depending on the direction of the wind. Elevations across the state range from about 3,100 to 13,800 feet, causing wide variations in temperature. Annual average delta SWE (new - older) Normals. During the winter months, these winds can persist along the eastern slope of the Continental Divide and often bring large temperature increases that lead to rapid snowmelt. Elk Mountain gets some kind of precipitation, on average, 73 days per year. Snoflo is the ultimate platform for outdoor enthusiasts and climate-conscious individuals. of blowing snow can as low as 100 kg/m3 (6.2 For each station, the records are corrected for the elevation difference between that station and Laramie according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. Snowy days (snowfall equal to at least one inch) more than doubles As noted in Figure 5.9.0., SWE is a function of altitude. Studies of wind flow patterns indicate that Wyoming is in the northern hemisphere. Under a higher emissions pathway, historically unprecedented warming is projected during this century (Figure 1). Despite average snowfall of over 450 inches in the Tetons, Togwotee Pass on the eastern border of Teton County receives a relatively modest average of 268 inches of snowfall despite sitting a similar elevation compared to Jackson Hole and Grand Targhee ski resorts. of normal when compared to it's Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies. NOAA Climate Science Building codes When using normals for any data element, Month Average High Average Low Average Precipitation Record High Record Low; January: 29F: 6F: 1.23 in: 55F (1974) . of moisture from passing weather systems. The weather pattern most favorable for precipitation is one with a low-pressure center slightly Brooklyn Lake Drifted snow is usually denser than undisturbed snow because the Climate Normals. The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th to 75th and 10th to 90th percentile bands. So meaningful state-wide averages for snowfall aren't available. The clearer part of the year in Laramie begins around June 4 and lasts for 4.6 months, ending around October 25. conditions lasted more than 43 hours. are forecasted to receive up to WY Observations The list of snowiest places in the United States by state shows average annual snowfall totals for the period from mid-1985 to mid-2015. Correlations improve using daily minimum temperatures. Another 25 percent of years receive less than 4.3 inches for the month. 2011: Hail. events exceeding five inches (Figure 5.1). Such variations have implications for water availability across the West, as snowmelt from the winter snowpack feeds many rivers and streams. Since most of the park lies at an elevation of 6,000 feet (1829 m) above sea level or higher, unpredictability characterizes Yellowstone's weather. For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Twitter National Drought Mitigation Center, Lincoln, NE. snowstorm and pile the snow into drifts several feet deep. occasions), that the snow actually fell when the minimum temperature was in the low to mid NOAA NCEI, 2012: State of the Climate: Laramie experiences some seasonal variation in monthly rainfall. Cheyenne, Wyoming gets 17 inches of rain, on average, per year. Temperatures near or above freezing will also impact the measurement of snowfall resulting When comparing minimum temperatures to maximum temperatures on the Snowfall drops off considerably as you drop into the valleys, on both the Jackson Hole side (WY) and the Teton Valley side (ID). history enables water managers to best estimate whether there will be a water surplus or The highest number of very hot days occurred during the 2000s and early 2010s (Figure 2). Hubbard, K. Robbins, L. Romolo, A. Akyuz, T.B. (PRISM, 1961-90), Figure 5.3. also transmit depth of snow at the site. water equivalent (1948-2001). The topography within 2 miles of Laramie contains only modest variations in elevation, with a maximum elevation change of 174 feet and an average elevation above sea level of 7,175 feet. Snow survey data can be used to help determine the weight that the snowpack exerts on the The thin dotted line is the corresponding average rainfall. Similarly in January, fresh snowfall in the heaviest years amounts to over 14 . Ocean and Gulf of Mexico, its high terrain enables uplift to squeeze out copious amounts Climate consists of the long-term averages of daily weather, usually in 30-year periods. Snowfall is almost always seen as depressing, but it haspositive mental health effects on some peopledue to theserenity it brings. Annual and Water Year Climate Summaries increase the snow load because a snowpack can absorb rain until its density is about 45%. Buckrail is brought to you in part by these community partners. WY SCO, 2011: Wyomings Climate: June Wehner, 2018: Our changing climate. Access a wealth of climate data and outdoor recreation reports, without ads. Lastly, the nighttime temperatures remain low, a few degrees above freezing, even during warm winter spells. The month with the most snow in Wyoming is February, with an average snowfall of 5.6 inches. Please try another search. As noted in Figure 5.6 and Figure 5.7, temperatures vary (NOAA/NWS/NCEI) Northeast October is typically the month's. Precipitation was more variable with below-average amounts in the northern and southern ends of the region and above-average amounts across the . The wetter season lasts 5.6 months, from April 6 to September 26, with a greater than 17% chance of a given day being a wet day. The state then experienced several years of above average precipitation until 2012, which was Wyomings driest year since historical records began in 1895. For example: The month with the most days of snow alone in Laramie is December, with an average of 2.0 days. Regional Climate Center, Reno, NV. High Temp: 80 F. Personal communication with Tom Perkins, Natural Resources Conservation Service. The black isolines are contours of constant solar elevation. Sites in the vicinity of trees might have accumulated more snow since the trees Roof snow loads can vary depending on melting and Total annual precipitation and the number of 1-inch extreme precipitation events have been trending upward since 2000. For these earlier sites, data were estimated or back-generated from 94" Table 5.C. The thin dotted lines are the corresponding average perceived temperatures.

Well also answer common questions about the Wyoming winter season climate or weather. snow occurred at Sheridan on the 3rd and 4th of April in 1955.47a During this period the This colder/shallower continental snowpack is weaker and more dangerous than the Tetons deeper intermountain snowpack, and as a result, avalanche danger is often greater and more unpredictable in the Togwotee Pass area. Sorry, the location you searched for was not found. (1 US gallon) * (1 ft3) * (62.418 lbs) * (1 ft) * SWE (inches) = Snow Load (lbs/ft2), (0.1337 ft3) (7.48 gallons) (1 ft3 of water) (12 inches). Mean Temp: 38 F. The type of snow itself, including the degree of crystallization and the observational interval used in some melting of the snow. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. Facebook 2011. The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year. Climate & Weather Averages in Jackson, Wyoming, USA. However, Alpine often receives heavier snow than Jackson since there is a gap in the terrain that allows moisture to stream through the Snake River Valley and Palisades unobstructed. Statewide Time Series, Wyoming. The snowfall totals are annual averages based on weather data collected from 1981 to 2010. The more One would expect that colder days yield lesser amounts . In May last year, temperatures in parts of Spain exceeded 40C as a mass of hot, dry air brought temperatures between 10C and 15C above the seasonal average and more akin to high summer.

The tourism score favors clear, rainless days with perceived temperatures between 65F and 80F. Jackson Holes mid-mountain at 8,180 feet also averages an impressive 390 inches of snow. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Lastly, the Continental Divides western part usually has the heaviest snowfall during mid-winter. Administration, National Centers for Environmental Information, Asheville, NC. Yearly variations in late-season snowpack depths are large; for example, April 1 snow water equivalent (the amount of water contained within the snowpack) at Lewis Lake Divide has ranged from less than 20 inches to more than 50 inches since 1981 (Figure 5). Figure 5.6. They usually last for a day or two. National Oceanic and Atmospheric Wyoming experiences significant seasonal variation in monthly snowfall. Wyoming SNOW REPORT.

Finally, having a home with a Wyoming snow fence would be the perfect choice if you plan to retire in the state. Town of Jackson Snowfall versus surrounding valley locations. 52.7. The month with the most snow in Laramie is April, with an average snowfall of 4.9 inches. The snow load calculated in Table 5.A. Considering whether this apparent problem has been systematic or not, the number of days The Jackson Hole Valley and Town of Jackson see a similar peak in snowfall in December and January, with February and November coming in as the next snowiest months. 20 inches over the lower portion and 30 to 40 inches on the sides of the basin where Another indication of the overall trend of higher average temperatures is a generally below average number of very cold days since 2000 (Figure 4c). Details on observations and projections are available on the Technical Details and Additional Information page. Snow and Avalanche [30-Year Normals 19912020]. Table 5.A. The brighter period of the year lasts for 2.8 months, from May 14 to August 6, with an average daily incident shortwave energy per square meter above 6.9 kWh. amount of water in the snowpack measured in inches if you were to melt the snowpack. The month with the least rain in Laramie is December, with an average rainfall of 0.0 inches. States. To know how much snow Wyoming gets, below is a table summary of the average heavy snowfall in selected areas in the state from 1991 to 2020. Check out this information for planning a winter visit. The black lines are lines of constant solar elevation (the angle of the sun above the horizon, in degrees). These numbers are obtained from theUS National Centers for Environmental Informationsrecords. Higher spring temperatures will also result in earlier melting of the snowpack, further decreasing water availability during the drier summer months. During the mid-winter months when the jet stream is the strongest, storms that pass over the Tetons and Yellowstone lose a lot of their moisture and Togwotee Pass will see more modest snowfall amounts as a result. The most noticeable drop-off in Yellowstone snowfall occurs over the north, where the altitude drops from 7,500-8,000 feet to 6,000-7,000 feet. reaches its maximum SWE. Average monthly snowfall at Togwotee Pass is very similar from November through April, and in fact, April is the snowiest month on average by a small margin. A good rule of thumb for determining snowfall is to melt whatever snow has accumulated ratios reveal that the highest ratios occur when the total daily precipitation amounts are the Wyoming average annual snowfall days of at least five inches Tools Environment. more problematic with the introduction of the Automated Surface Observing System This storm began in eastern Utah and tracked northeast over 750 miles before ending in North Dakota. Lincoln, NE, 8 pp. Stevens, S.E. Drought Indices: Maps [January 1996May 2015]. explain why the snow-to-water ratios were not higher.
