dashboard

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 snow, light rain, and moderate rain.

Light snow is the most severe precipitation observed during 42% of those days with precipitation. It is most likely around March 1, when it is observed during 6% of all days.

Light rain is the most severe precipitation observed during 23% of those days with precipitation. It is most likely around March 12, when it is observed during 3% of all days.

Moderate rain is the most severe precipitation observed during 22% of those days with precipitation. It is most likely around March 1, when it is observed during 2% of all days.

Relative frequency of various types of precipitation over the course of a typical March.

The likelihood of snow falling is highest around March 1, occurring in 7% of days.

Probability of Snow Fall Being Reported in a Given Day in March

Probability that snow will be reported at least once in a given day.

Either snow rarely accumulates at this location in March or snow depth measurements are unavailable or unreliable.

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 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 11°F (dry) to 30°F (dry) and is rarely below -3°F (dry) or above 42°F (dry).
