Plot Description:

This application presents a calendar of Storm Prediction Center or Weather Prediction Center outlooks by state, WFO, or county. The GIS spatial operation done is a simple touches. So an individual outlook that just barely scrapes the selected area would count for this presentation. Suggestions would be welcome as to how this could be improved.

This app attempts to not double-count outlook days. A SPC/WPC Outlook technically crosses two calendar days ending at 12 UTC (~7 AM). This application considers the midnight to ~7 AM period to be for the previous day, which is technically not accurate but the logic that most people expect to see.

When plotting hail, tornado, or wind probabilities, a "H" will appear on days that had "hatched"/"SIGNificant" risk. Note that this isn't an exact science as the hatched and probability risk are not checked to see if they spatially/temporally overlap each other.

Updated 15 July 2025: An option was added to just plot a single threshold. This logic gets a bit tricky as consider an example of Iowa being engulfed by a moderate risk, but you choose to only plot enhanced risk days. The plot would show an enhanced risk for that day eventhough it was a moderate.
