Upper Air Maps
SPC Upper Air Maps Maps and derived fields based on twice daily (00 and 12 UTC) radiosonde data over the continental U.S.
Observed Sounding Analysis
Observed Sounding Analysis Skew-T charts for all observed soundings across the United States. Many experimental forecast tools and parameters are shown.
Mesoanalysis Graphics
SPC Hourly Mesoscale Analyses Nine fixed regional sectors and a national sector provide hourly gridded mesoanalysis graphics across the CONUS.
Short-Range Ensemble Forecast (SREF)
SPC Short-Range Ensemble Forecast (SREF) Page
Short-Range Ensemble Plumes
SPC SREF Plumes Page The SPC SREF Plumes Page displays point forecasts for each of the 21 members of the NCEP Short-Range Ensemble Forecast (SREF) system. Forecasts are generated for over 1000 stations with archived data and some observational verification for CONUS WFO locations.
Storm-Scale Ensemble of Opportunity (SSEO)
SPC Storm-Scale Ensemble of Opportunity (SSEO) Page The SPC Storm-Scale Ensemble of Opportunity (SSEO) is produced by postprocessing seven (7) deterministic convection-allowing model runs. Special emphasis is placed on hourly maximum storm-attribute fields.
Fire Weather Composite Maps
Fire Weather Graphical Composite Maps Forecast and observational maps for various fire weather variables based on the NAM and RAP models.
Compmap
SPC Graphical Composite Maps This dynamic web page uses Javascript and cascading style sheets to display hourly RAP model graphics, surface weather, and NCEP graphics. The user can overlay the different graphics to produce a web-based "composite map".
