Probability of Precipitation at Some Point in the Day in April

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

Moderate rain is the most severe precipitation observed during 45% of those days with precipitation. It is most likely around April 1, when it is observed during 6% of all days.

Thunderstorms are the most severe precipitation observed during 32% of those days with precipitation. They are most likely around April 1, when it is observed during 4% of all days.

Light rain is the most severe precipitation observed during 20% of those days with precipitation. It is most likely around April 3, when it is observed during 2% of all days.

Relative Humidity in April

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 April, the dew point typically varies from 48°F (dry) to 68°F (muggy) and is rarely below 35°F (dry) or above 74°F (very muggy).
