Probability of Precipitation at Some Point in the Day in March

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 March, the most common forms of precipitation are light rain, moderate rain, moderate snow, and thunderstorms.

Light rain is the most severe precipitation observed during 51% of those days with precipitation. It is most likely around March 9, when it is observed during 25% of all days.

Moderate rain is the most severe precipitation observed during 22% of those days with precipitation. It is most likely around March 22, when it is observed during 11% of all days.

Moderate snow is the most severe precipitation observed during 13% of those days with precipitation. It is most likely around March 1, when it is observed during 8% of all days.

Relative Humidity in March

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 March, the dew point typically varies from 31°F (dry) to 44°F (dry) and is rarely below 25°F (dry) or above 48°F (dry).

Wind Directions in March

The fraction of time spent with the wind blowing from the various directions over the entire year. Values do not sum to 100% because the wind direction is undefined when the wind speed is zero.

Fraction of Time Spent with Various Wind Directions in March

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.
