1. What is the Snow Day Percentage Calculator?

The Snow Day Percentage Calculator estimates the probability of a snow day based on snowfall amount, ice accumulation, and temperature. It helps schools, businesses, and individuals prepare for winter weather disruptions.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Snowfall \) — Amount of snowfall in inches
• \( Ice \) — Ice accumulation in inches
• \( Temperature \) — Current temperature in °F

Explanation: The formula weights ice more heavily than snow (20x vs 10x) and accounts for temperature effects, with colder temperatures increasing the snow day probability.

3. Importance of Snow Day Prediction

Details: Accurate snow day prediction helps schools make timely closure decisions, allows businesses to plan for reduced staffing, and helps families prepare for potential home days.

4. Using the Calculator

Tips: Enter snowfall and ice amounts in inches, temperature in Fahrenheit. For best results, use measurements from official weather reports.

5. Frequently Asked Questions (FAQ)

Q1: What percentage typically results in school closures?
A: Most schools consider closure when the probability exceeds 70%, though this varies by district.

Q2: How accurate is this calculator?
A: It provides a general estimate but doesn't account for all factors like road conditions or local policies.

Q3: Should I use current or forecasted temperatures?
A: For morning decisions, use the forecasted morning low temperature.

Q4: Does wind chill affect the calculation?
A: This calculator uses actual temperature only. Extreme wind chills may warrant additional consideration.

Q5: What time of day should I check?
A: Check early morning (5-6 AM) for most accurate current conditions.
