Precipitation

There is a 5% chance that precipitation will be observed at some point during the day.

Probability of Precipitation

The fraction of days in which various types of precipitation are observed. If more than one type of precipitation is reported in a given day, the more severe precipitation is counted. For example, if light rain is observed in the same day as a thunderstorm, that day counts towards the thunderstorm totals. The order of severity is from the top down in this graph, with the most severe at the bottom.

When precipitation does occur it is most often in the form of moderate rain (32% of days with precipitation have at worst moderate rain), slight rain (29%), drizzle (23%), and thunderstorms (13%).
