For more information on the National Gridded Snowfall Analysis, see the Product Description Document (PDD).The climatological snowfall to liquid equivalent ratio (SLR) data used to generate the snowfall background (first guess) are available here. See the latest Illinois Doppler radar weather map including areas of rain, snow and ice. The snow forecast map shows the forecast snowfall in inches for the current day.(Look under the "Select Physical Element" dropdown for "SF Analysis" items.) The 24, 48, and 72 hour accumulations can also be browsed on an interactive map.Observing networks, including ASOS, COOP, CoCoRaHS, Mount Baker in Washington received nearly 850 inches (more. Snowfall observations are provided by numerous no stranger to snow shattered records in late December when the city got more than four feet of snow in just 30 hours. The 24, 48, and 72 hour accumulations can also be browsed on an interactive map. Several operational data sets into a unified analysis. The National Gridded Snowfall Analysis estimates snowfall in the recent. Station icons are drawn with larger circles to represent greater snow depth readings. Though the record-deep snowpack will bring welcome water supply benefits to large swaths of the West in the spring, it also poses a greater risk of flooding as the snow melts, especially if temperatures rise quickly.Home Snow Information National Analyses Interactive Maps 3D Visualization Airborne Surveys Snowfall Analysis Satellite Products Forecasts Data Archive SHEF Products Observations near Science/Technology NOHRSC GIS Data Sets Special Purpose Imagery About The NOHRSC Staff NOAA Links Snow Climatology Related Links Help Help and FAQ Site Map Contact Us Please Send Us Comments!Įstimates snowfall in the recent past by gathering > Twin Cities, MN > Latest Snowfall Reports - National Weather Service Twin Cities/Chanhassen MN. See the latest North Carolina Doppler radar weather map including areas of rain, snow and ice. The extremely wet Western winter has also improved the long-term precipitation shortfalls that had accumulated over several years, bringing parts of western Oregon, southern Idaho, Nevada and central Utah out of extreme drought. Healthy snowpack and replenished reservoirs have helped ease California out of its long-term drought, the driest three-year stretch on record. In the southern Sierras, which generally receives less snow, average snowpack levels reached 62.6 inches, nearly triple the historical amount. On that day, the average statewide snowpack levels - as measured by the amount of liquid water available in the snow - were more than double the historical average for California. The Snow and Water Interactive Map displays both current and historic hydrometeorological data in an easy-to-use, visual interface. Warming temperatures over the past decades have generally resulted in snow that is concentrated at colder, higher elevations, said David Simeral, a research scientist with the Desert Research Institute.Ĭolder-than-normal temperatures across much of the West also helped build up and sustain a deep snowpack in California’s Sierra Nevada and parts of the intermountain West, including northern Arizona, western Colorado, Nevada and Utah.Īpril 1 is a benchmark date for when water managers expect snowpack to peak. Some of that winter snow fell at unusually low elevations, from a range of 500 to 2,000 feet, a rare sight in regions like the hills overlooking the San Francisco Bay Area.

Note: The Center for Western Weather and Water Extremes determined the atmospheric river events that made landfall in or heavily impacted California based on approximate latitude, strength and timing of storms.
