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 thunderstorms, moderate rain, and lightrain.

Thunderstormsare the most severe precipitation observed during 36% of those days with precipitation.

They are most likely around September 21, when it is observed during 4% of all days.Moderate rainis the most severe precipitation observed during 32% of those days with precipitation. It ismost likely around February 15, when it is observed during 3% of all days.

Light rainis the most severe precipitation observed during 28% of those days with precipitation. It ismost likely around February 26, when it is observed during 2% of all days.

The average daily high (blue) and low (brown) relative humidity with percentile bands (inner bands

from 25th to 75th percentile, outer bands from 10th to 90th percentile).

Dew PointDew point is often a better measure of how comfortable a person will find the weather than relativehumidity because it more directly relates to whether perspiration will evaporate from the skin, therebycooling the body. Lower dew points feel drier and higher dew points feel more humid.

Over the course of a year, the dew point typically varies from -6C (dry) to 13C (very comfortable) and

is rarely below -11C (dry) or above 18C (mildy humid).

There are two periods in the year that are most comfortable: The first is between May 29 and June 25 andthe second is between July 9 and October 23. The air feels neither too dry nor too muggy during these
