The probability of precipitation is simply a statistical probability of 0.01 inch or more of precipitation at a given area in the given forecast area in the time period specified. For example, if a forecast for a given location says that there is a 40% chance of rain this afternoon, then there is a 40% chance of rain at any point in that location for noon to 6 p.m. local time.
The humidity percentage represents the relative humidity on a 100% scale, and tells you how saturated the air is with moisture. The higher the value, the more humid (and potentially “sticky”) it will feel.

The wind arrows point in the direction in which the wind is blowing. An arrow pointing south represents a northerly wind originating from the north and moving south.

The color range is from blue to red. The blue indicates a lower value while the red indicates a much higher value. A white hue indicates a value somewhere in the middle.

All gusts are a type of wind. A gust is a sudden increase of the wind’s speed that lasts no more than 20 seconds. This usually occurs when wind speeds reach a peak of at least 16 knots. A wind gust usually comes in 2-minute intervals.
