Please consult your device documentation for instructions. On mobile devices, you can save the bookmark as an easy-access icon similar to other apps. offers you the most accurate and up-to-date weather forecast maps for the entire US. For example, if you select "Weather for a location," then select a location, the bookmark will return to your location on your next visit. The Current Radar map shows areas of current precipitation (rain, mixed, or snow). You may bookmark the URL to return later to the same view with the selected settings. Follow along with us on the latest weather were watching, the threats it may bring and check out the extended forecast each day to be prepared. The URL will automatically update as you select the view and settings. ![]() This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. The same idea applies to the precipitation normal values, except enhanced odds forĪbove- (below-) normal precipitation values are green (brown).This site is organized into views that provide relevant radar products and weather information for a common task or goal. If the selected point is within an area of enhanced odds forīelow-normal temperatures, the shading around the normal maximum/minimum temperature will appear blue. Southwest to west winds 5 to 10 mph, becoming north and increasing to near 15 mph this afternoon. A slight chance of thunderstorms through early afternoon. If the selected point is withinĪn area of enhanced odds for above-normal temperatures, the shading around the normal maximum/minimum temperature will appear red. TODAY.Mostly cloudy with a chance of showers. ![]() The color used to highlight the normal values (precipitation or maximum/minimum temperature) are used to delineate the category of the forecast at the point clicked. What does the highlighting around the normal precipitation or normal maximum/minimum temperature imply? What color scheme is used? The color scheme follows that of the static images for the 6-10 day forecasts and 8-14 day forecasts. ![]() Intervening values are linearly interpolated, combined with data from the COOP, and averaged over the 7-day period to createĪverage maximum/minimum temperature normals. For temperatures, monthly average maximum/minimum temperatures are assigned to theġ5th of the current month and subsequent month. ![]() These values are then summed over the 7-day period to create total precipitation normals. Radar Maps, Satellite Maps and Weather Maps for the Eastern United States and Western Atlantic including Infrared Satellite, Visible Satellite, Water Vapor Satellite, Radar Maps and Model Maps for the Eastern US Coast. PRISM data are inherently available as monthly values.įor precipitation, daily average values are calculated (Monthly Total/Number of Days in Month) and combined with data from the Cooperative Observer Network (COOP). AccuWeather’s fall forecast has been released and our long-range experts say some parts of the United States could see. PRISM (Parameter-elevation Regressions on Independent Slopes Model) normals are used in this display. Published 5:23 AM PST Updated 6:07 AM PST. Many thanks to the staff there for developing the prototype and assisting in the transition to CPC.įAQ What climatologies are used in this display? This webpage was developed in conjunction with the Weather Forecast Office in Pendleton, Oregon (WFO PDT).
