Compare storm events with design storm values

[gherrman]

I see great potential here for a script/GUI that can be used to check if peak rainfall intensities/depths for a given storm event exceed the design storm values (10yr-24hr, 25yr-24hr, etc). Many stormwater projects and conservation practices are based on a design storm, values for which can be found on the NOAA Atlas 14 PPF server and can be downloaded as CSV files (data should be static as updates are only published every couple of years). Historical rainfall data for local storm events is available through Synoptic. Their API can be used to find the closest weather stations to a given location (i.e. active stations within a 10 mile radius of a lat/long point). Those stations can then be queried for precipitation data during a specific timeframe. The queried precipitation data can be used to created a weighted arithmetic mean value for the location of interest by weighting the station values based off of their proximity to said location (grid coordinates for the location of interest and weather stations are available in the form of decimal lat-long values).
