Cloud Cover Types

The fraction of time spent in each of the five sky cover categories. From top (most blue) to bottom (most gray), the categories are clear, mostly clear, partly cloudy, mostly cloudy, and overcast. Pink indicates missing data. Outside the United States clear skies are often reported ambiguously, leading them to be lumped in with the missing data.

There is a 24% chance that precipitation will be observed at some point during the day.

Probability of Precipitation

View in
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.

When precipitation does occur it is most often in the form of moderate rain (43% of days with precipitation have at worst moderate rain), slight rain (33%), and thunderstorms (21%).

Precipitation is most likely around 10am and least likely around 1am.

Types of Precipitation

Relative frequency of various types of precipitation over the course of a typical March 15.

Either snow is exceptionally unlikely to fall at this location on March 15 or this station does not reliably report precipitation types.

The relative humidity typically ranges from 68% (mildly humid) to 91% (very humid), rarely dropping below 62% (mildly humid), or exceeding 99% (very humid).

The air is driest at 2pm, at which time the relative humidity is less than 72% (humid) three days out of four; it is most humid at 4am, exceeding 86% (very humid) three days out of four.

Relative Humidity

Average hourly humidity (black line) with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

The dew point ranges from 74°F to 75°F with an average of 75°F, which feels muggy no matter what the relative humidity is.

For reference, comfortable indoor conditions should have a relative humidity between 30% and 50% with a dew point of less than 65°F.

Average hourly wind speed (black line) with percentile bands (inner bands from 25th to 75th percentile, outer bands from 10th to 90th percentile).

The wind is most often out of the east (21% of the time) and north east (13% of the time). The wind is least often out of the north west (0% of the time), west (1% of the time), south (1% of the time), north (1% of the time), and south west (1% of the time).

Wind Directions

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

Wind Directions Over Day

The fraction of time spent with the wind blowing from the various directions on an hourly basis. Values do not sum to 100% because the wind direction is undefined when the wind speed is zero.
