Median hourly cloud coverage fraction (black line) with percentile bands (inner band from 40th to 60th percentile, outer band from 25th to 75th percentile).
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.
Precipitation
There is a 65% chance that precipitation will be observed at some point during the day.
Probability of Precipitation
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 slight rain (44% of days with precipitation have at worst slight rain), moderate rain (31%), thunderstorms (16%), and drizzle (6%).
Precipitation is most likely around 4pm and least likely around 3am.
