Drifting snow may occur during or after snowfall. Wind chills are produced by a combination of wind speeds coupled with the current outdoor air temperature. This resultant temperature produced would be what the temperature would feel like on bare skin. Basically, increased wind speeds increase rapidly heat loss from exposed skin. The National Weather Service uses -20 degrees Fahrenheit as a general rule for a threshold for potentially dangerous wind chill conditions.
Chinook winds are warm, dry winds that occur on the lee- side of high mountain ranges.
Frequently, they occur along the mountains in the western half of the contiguous United States and in Alaska. These winds can develop in major urban areas and are often very strong. Large amounts of snow can melt from strong Chinook winds. I need climate information.
