The probability that precipitation will be observed at this location varies throughout the year. Precipitation is most likely around January 6, occurring in 82% of days. Precipitation is least likely around August 26, occurring in 47% of days.
Probability of Precipitation at Some Point in the Day
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.
Over the entire year, the most common forms of precipitation are light rain, light snow, and moderate rain.
Light rain is the most severe precipitation observed during 29% of those days with precipitation. It is most likely around May 17, when it is observed during 29% of all days.
Light snow is the most severe precipitation observed during 25% of those days with precipitation. It is most likely around January 17, when it is observed during 44% of all days.
Moderate rain is the most severe precipitation observed during 18% of those days with precipitation. It is most likely around October 10, when it is observed during 18% of all days.
Types of Precipitation Throughout the Year
Relative frequency of various types of precipitation over the course of a typical year.
During the warm season, which lasts from June 6 to September 14, there is a 51% average chance that precipitation will be observed at some point during a given day. When precipitation does occur it is most often in the form of light rain (46% of days with precipitation have at worst light rain), moderate rain (27%), thunderstorms (14%), and drizzle (8%).
