Clear Skies
Clear skies occur when little or no cloud cover is present, leaving most or all of the sky unobstructed by clouds.
SnowStorms
Low Cloud Cover
Low cloud cover occurs when clouds form close to the ground, often creating grey or overcast skies and sometimes reducing visibility.
Cold Wave
A cold wave is a prolonged period of unusually cold weather when temperatures remain significantly below normal for a region and time of year.
Snowband
A snowband is a narrow area of concentrated snowfall that can produce much heavier snow than nearby locations.
Lake-Effect Snow
Lake-effect snow forms when cold air moves across relatively warmer, open lake water, picking up moisture that later falls as snow downwind.
Ground Blizzard
A ground blizzard occurs when strong winds lift loose snow from the ground, causing severely reduced visibility even when little or no new snow is falling.
Blowing Snow
Blowing snow occurs when wind lifts loose snow from the ground and carries it through the air, reducing visibility and causing snow to drift.
Whiteout
A whiteout is a weather condition where snow and poor visibility make it difficult or impossible to see the horizon and surrounding features.
Snowdrift
A snowdrift is a pile or bank of snow that forms when wind carries loose snow and deposits it in another location.
Snow Squall
A snow squall is a sudden period of heavy snow that can quickly reduce visibility and create dangerous driving conditions.
