Probability of Precipitation at Some Point in the Day in February

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

Thunderstorms are the most severe precipitation observed during 36% of those days with precipitation. They are most likely around February 29, when it is observed during 5% of all days.

Light rain is the most severe precipitation observed during 32% of those days with precipitation. It is most likely around February 25, when it is observed during 3% of all days.

Moderate rain is the most severe precipitation observed during 25% of those days with precipitation. It is most likely around February 23, when it is observed during 2% of all days.

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 February, the dew point typically varies from 62°F (comfortable) to 73°F (very muggy) and is rarely below 56°F (comfortable) or above 76°F (very muggy).
