Plot Description:

This app generates infographics for the Storm Prediction Center or Weather Prediction Center outlooks. The trick here is how the valid time works. The app will first attempt to match an issuance to that timestamp, if it fails, it then looks backwards in time for the most recent issuance to that timestamp.

Another bit of ambiguity is which outlook you get between about midnight and the 13z issuance of the Day 1 Outlook. In this case and as the code stands now, you get the next day's outlook.

A GIS Shapefile download option exists for downloading these outlooks in-bulk.


Based on a sampling of recent timings for this application, plot generation time has averaged 7 seconds. Hold on for the plot is generating now!
