What does VR mean in weather?

variable wind direction
A wind direction of VR indicates a variable wind direction during the hour.

How is QPF calculated?

The conditional QPF is then (0.80)/(0.70) or approximately 1.14 which is now the value μ. So the equation for cPOE for determining the chance of exceedance of 1.00 inch produces the following: cPOE(1) = e^(-1/μ) = e^(-1/(1.14)) = 0.41 = 41%.

## What is QPF snow?

QPF represents the total amount of liquid precipitation (in inches) expected during specific periods, typically 6 or 24 hours, at any point or basin in the forecast area.
