The average probability that some form of precipitation will be observed in a given day is 12%, with little variation over the course of the month.

Probability of Precipitation at Some Point in the Day in November

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.

Throughout November, the most common forms of precipitation are light rain, thunderstorms, and moderate rain.

Light rain is the most severe precipitation observed during 50% of those days with precipitation. It is most likely around November 25, when it is observed during 7% of all days.

Thunderstorms are the most severe precipitation observed during 21% of those days with precipitation. They are most likely around November 2, when it is observed during 4% of all days.

Moderate rain is the most severe precipitation observed during 20% of those days with precipitation. It is most likely around November 18, when it is observed during 3% of all days.

Relative Humidity in November

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 Point

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

Over the course of a typical November, the dew point typically varies from 23°F (dry) to 40°F (dry) and is rarely below 7°F (dry) or above 52°F (very comfortable).

Dew Point in November

Fraction of Time Spent with Various Wind Directions in November

The fraction of time spent with the wind blowing from the various directions on a daily basis. Stacked values do not always sum to 100% because the wind direction is undefined when the wind speed is zero.
