Day 1 Probabilistic Tornado Outlook

The Storm Prediction Center (SPC) Weather Outlooks Web Service offers various polygon layers representing Convection Outlooks from Day 1 to Day 3. These encompass Category Outlooks for Significant and Probabilistic Tornado, Hail, and Wind Outlooks. Additionally, the service provides layers displaying forecasted polygons for Day 4 to Day 8 Probabilistic Outlooks. Further details regarding the layers included in this map service are outlined below.Day 1 Layer contain: Separate 5-tier categorical, probabilistic tornado, hail and wind, significant tornado, hail and wind outlooks.Day 2 Layer contain: Separate 5-tier categorical, probabilistic tornado, hail and wind, significant tornado, hail and wind outlooks.Day 3 Layer contain: 5-tier categorical outlook, probabilistic severe, and significant severe.Days 4-8 Layers are all probabilistic outlooks.Update Frequency:Day 1 updates daily at 01Z, 06Z, 13Z, 16:30Z, and 20ZDay 2 updates daily at 06Z and 17ZDay 3 updates daily at 07:30ZDay 4-8 updates daily at 09ZLink to graphical web page: https://www.spc.noaa.govLink to data download (shapefile): https://www.spc.noaa.gov/gisDay 1: https://www.spc.noaa.gov/products/outlook/day1otlk-shp.zipDay 2: https://www.spc.noaa.gov/products/outlook/day2otlk-shp.zipDay 3: https://www.spc.noaa.gov/products/outlook/day3otlk-shp.zipDay 4: https://www.spc.noaa.gov/products/exper/day4-8/day4prob-shp.zipDay 5: https://www.spc.noaa.gov/products/exper/day4-8/day5prob-shp.zipDay 6: https://www.spc.noaa.gov/products/exper/day4-8/day6prob-shp.zipDay 7: https://www.spc.noaa.gov/products/exper/day4-8/day7prob-shp.zipDay 8: https://www.spc.noaa.gov/products/exper/day4-8/day8prob-shp.zipLink to metadataQuestions/Concerns about the service, please contact the DISS GIS teamTime Information: This service is not time enabled.
