the chance of 0.01 inches or more precipitation at the station
site for the 6- or 12-hour period ending at the specified time.
- Thunderstorm probability is the percent probability (0% - 100%)
of encountering a thunderstorm within the 6- or 12-hour period for
the 2.5km (1.5mi) sized grid box that includes the given site.
* QPF = Quantitative Precipitation Forecast (liquid water equivalent
total of all precipitation types over given period). Snow forecasts
provide 6-hour snowfall total in inches.
