How to Use the Snow Day Probability Calculator

The Snow Day Probability Calculator helps you determine the likelihood of a snow day by considering various weather conditions and their severity. Follow the instructions below to effectively use this calculator and interpret its results.

Step 1: Enter the Current Temperature

  • Locate the input field labeled “Current Temperature (°F)”.
  • Enter the current temperature in degrees Fahrenheit in the provided field. This value must be between -20°F and 40°F.

Step 2: Input Expected Snow Accumulation

  • Find the field labeled “Expected Snow Accumulation (inches)”.
  • Input the predicted snowfall in inches. Acceptable values range from 0 to 36 inches.

Step 3: Enter Wind Speed

  • Locate the field marked “Wind Speed (mph)”.
  • Input the forecasted wind speed in miles per hour. The wind speed should be between 0 and 75 mph.

Step 4: Select Snow Timing

    • Dry and Clear

Step 6: Review Results

Upon entering all required inputs, the calculator provides the following results:

  • Snow Day Score: This value indicates the overall score based on current weather and road conditions. Scores are expressed in points and reflect the severity of conditions that could lead to a snow day.
  • Snow Day Probability: Expressed as a percentage, this represents the likelihood of a snow day occurring based on the calculated score.
  • Weather Severity Index: This figure reflects the severity of the current weather conditions considering snow amount, wind speed, and temperature effects.

Use this information to make informed decisions about potential schedule adjustments due to adverse weather conditions.
