This is a simple cli tool that will return some weather data from a limited dataset. To request the data, use the command like this:
npm run historical_weather <function-name> [options]
You can also run it with bash like this:
./historical_weather.sh <function-name> [options]
There are two functions available: days-of-percip and max-temp-delta
days-of-percip will give you the average days of percipitation, rain or snow, for the city averaged over a 10 year period.
max-temp-delta will give the day of largest temperature difference for the chosen city in the chosen date range.
Both take a city as their first option, which can be bos, jnu, or mia which represents Boston, MA, Juno, AK and Miami, FL respectively.
max-temp-delta take further arguments of a 4-digit year and a 2-digit month. These arguments are optional, but if a month is given, a year is also required.
