The raininess of a location is indicated with the predicate #$raininessOfRegion.

> The predicate #$weather is used to describe the weather at a particular outdoor location. (#$weather LOC WEATHER) means that the #$OutdoorLocation LOC is an instance of the #$OutdoorLocationByWeatherType WEATHER. For example, to say that it's snowy in Lake Tahoe, we would say: (#$weather #$LakeTahoe #$Snowy). Note that multiple sorts of conditions can characterize the weather at a given region at a given time; thus the truth of (#$weather #$LakeTahoe #$Snowy) does not rule out the possiblity of (#$weather #$LakeTahoe #$Cloudy) also being true.
