Cloudy period Mainly Sun
Mainly Sunny - Clear, with a small area of clouds visible. Cloud cover will be between 1/10 and 3/10.

Sunny with Cloudy Periods - Mostly clear, with times when about half of the sky will be covered in clouds. Cloud cover will be between 3/10 and 5/10.

Variable Cloud
At times there will be more clouds than sun, and at other times there will be more sun than clouds. Cloud cover will be between 4/10 and 6/10.

Cloud with Sunny Breaks
A least half covered in clouds, but not totally cloudy. Cloud cover will be between 6/10 and 8/10.

Freezing Rain
Supercooled liquid rain drops that freeze on contact with the ground. Freezing rain will form a layer of ice on any surface instantly.

Few Showers
Rain Showers - Intermittently falling rain, generally short-lived.

Mainly Sunny with a Chance of Showers - The sky is expected to be less than half covered with clouds, but there still may be brief periods of precipitation, generally occuring in the late afternoon.

Thunder Showers
Thunder Showers - Intermittent rain showers with thunder and lightning, generally short-lived.

Mainly Sunny with a Chance of Thunderstorms - The sky is expected to be less than half covered with clouds, but there still may be brief periods of showery precipitation with thunder and lightning, generally occuring at the end of the afternoon.

Variable Cloudiness with a Chance of Thundershowers - The sky is expected to be at least half covered with clouds, with some showers possible; thunder and lightning may be associated with the showers. The showers may be quite heavy, but will be short-lived.

Variable Cloudiness with a Risk of Thundershowers - The sky is expected to be at least half covered with clouds, with a very slight chance of some showers; thunder and lightning may be associated with the showers. The showers may be heavy, but will be short-lived.

Variable Cloudiness with a Risk of Thunderstorms - he sky is expected to be at least half covered with clouds, with some showers possible; thunder and lightning may be associated with the showers. The showers may be very heavy and last for a long period of time.

Cloudy
No sunshine visible. Cloud cover will be 10/10.

Cloudy with Drizzle
The sky will be overcast and a heavy mist or very light continuous rain is expected to fall. Your slow pulse wipers will be too fast in clearing the windshield.

Rain
The sky will be overcast and the precipitation continuous, with water droplets greater than 0.5mm in size. Things will get wet very quickly. The rain will interfere with outdoor activities. Puddles will form quickly, water will generally run down expressways, and reduced visibility while driving may be a problem.

Thunder Storms
Cloudy with Thunderstorms - The sky will be cloudy, with showers or light rain possible; thunder and lightning will be associated with the precipitation. The showers or rain will be heavy for extended periods of time.

Wet Flurries
Wet Snow - The sky will be overcast and the precipitation continuous. The snow will be partially melted before reaching the ground and can either accumulate as sticky, heavy snow or instantly melt on contact. Visibility will be reduced and roadways very slippery.

Rain or Snow
Rain or Snow - The type of precipitation expected to fall will be either rain or snow throughout the forecast period. The precipitation will be continuous. If the precipitation is snow, accumulations can be significant, visibility will be reduced and roadways can be slippery.

Cloudy with Rain or Snow Showers - The type of precipitation expected to fall can either be rain or snow throughout the forecast period. The precipitation starts and stops. No significant accumulations are expected. If the precipitation falls as snow, visibility will be reduced and roadways can become slippery.

Few Flurries
Flurries - Intermittently falling snow, generally short-lived. Flurries are the solid equivalent of "Rain Showers".

Snow/Snowsqualls
Snow - Continuously falling snow, which can be long-lived. Snow is the solid equivalent of rain.

The sky will be overcast and the snow continuous. The snow can amount to significant accumulations but usually will not exceed 3cm during the forecast period. Visibility will be reduced, roadways slippery, and snow may accumulate on roadways with the absence of salt trucks. If more than 3cm of snow is expected to fall within a forecast period, the snow forecast will call for "3 to 5 cm of snow", "5 to 10 cm of snow", or "more than 10 cm of snow".

Snowsqualls - Snowsqualls are created when winds blow over an open body of water. Downwind and onshore, the squalls can carry strong winds and produce significant accumulations of snow. Visibility will be reduced, roadways slippery, and snow may accumulate on roadways with the absence of salt trucks. Snowsqualls are typically very localized phenomena.

Flurries
Flurries - Intermittently falling snow, generally short-lived. Flurries are the solid equivalent of "Rain Showers".

Cloudy with Light Snow - The cloud cover will be as described for "Cloudy", the precipitation light. The snow will be continuous but will not usually amount to any significant accumulations for the forecast period. Visibility will be reduced and roadways can be slippery, depending on the duration of the snow.

Fog
A cloud with its base at the Earth's surface. Visibility is reduced to less than 1 km.

Clear
Clear - Skies will be almost totally clear, perhaps with a few small light clouds visible. Cloud cover will be between 0 and 1/10. Clear is the nighttime term equivalent to "Sunny".

Mainly Clear - The nighttime equivalent of "Mainly Sunny".

Cloudy Period
Clear with Cloudy Periods - The nighttime equivalent of "Sunny with Cloudy Periods".

Variable Clouds
The nighttime equivalent of "Variable Cloud".

Cloud with Clear Breaks
Cloudy with Clear Breaks - The nighttime equivalent of "Cloudy with Sunny Breaks".

Blowing Snow
Created when high winds lift snow from the surface and blow it to heights of 2 meters or more. No snow will be falling, but visibility may be severely reduced and roadways can be slippery.

Chance of Showers
Mainly Clear with a Chance of Showers - The sky is expected to be less than half covered with clouds, but there still may be brief periods of precipitation, generally occuring in the early evening.

Risk of Thunder-Showers
Variable Cloudiness with a Risk of Thunderstorms - The sky is expected to be at least half covered with clouds, with some showers possible; thunder and lightning may be associated with the showers. The showers may be very heavy and last for a long period of time.

Wet Flurries
Wet Snow - The sky will be overcast and the precipitation continuous. The snow will be partially melted before reaching the ground and can either accumulate as sticky, heavy snow or instantly melt on contact. Visibility will be reduced and roadways very slippery.

Few Flurries
Flurries - Intermittently falling snow, generally short-lived. Flurries are the solid equivalent of "Rain Showers".
