Periods of snow refer to different types of snowfall events, each characterized by varying intensity and duration. These can range from brief, light flurries to intense snowstorms.
Types of Snowfall Periods
Here's a breakdown of common snowfall periods, based on the provided reference:
| Snowfall Period | Description | Intensity | Duration | Accumulation | Wind |
|---|---|---|---|---|---|
| Snow Flurry | An intermittent, light snowfall event of short duration with only a trace level of accumulation. | Light | Short | Trace | Light |
| Snow Squall | A brief but intense period of moderate to heavy snowfall with strong, gusty surface winds and measurable snowfall. | Moderate to Heavy | Brief | Measurable | Strong, Gusty |
| Thundersnow | Occurs when a snowstorm generates lightning and thunder. | Variable | Variable | Variable | Variable |
Detailed Explanation:
- Snow Flurries:
- These are the lightest form of snowfall periods.
- They often come and go quickly, with no significant accumulation.
- They might create a dusting on surfaces but typically don't lead to major travel disruptions.
- Snow Squalls:
- These are more intense than flurries.
- They involve a sudden burst of heavy snowfall accompanied by strong winds.
- Visibility can drop sharply during a snow squall, posing a hazard for driving.
- Accumulation can be quick and measurable, leading to slippery road conditions.
- Thundersnow:
- This is a more unusual event, where a snowstorm is accompanied by lightning and thunder, like a summer thunderstorm but with snow.
- This type of snowfall can be variable in intensity, duration and amount of accumulation depending on the specific storm dynamics.
Practical Implications
Understanding the different types of snow periods helps you better prepare for the weather. For example:
- If you hear about snow flurries, you can expect a brief period of light snow that is unlikely to significantly impact your plans.
- A snow squall warning, however, calls for more caution, as these can create hazardous travel conditions very quickly.
- Thundersnow suggests an intense snowstorm where other risks such as lightning strikes must be taken into consideration.
By knowing the specific type of snowfall period, you can make informed decisions about travel and outdoor activities.
