Data from the Climate Data Online tool provided by NOAA.

Assumptions

• Though what we think of as 'precipitation' usually includes snowfall, somewhat confusingly, the PRCP column of the NOAA data looks like it does not include SNOW (e.g., line 12 - PRCP: 2.3, SNOW: 43.0). So in calculating the days of precipitation, I have considered a nonzero value in either of these columns as counting towards a day of precipitation.
