Factors Affecting Snow Melt in Tulsa After the Cold Snap

The unusually slow Tulsa snow melt following the recent record cold snap wasn't a simple matter of warmer temperatures eventually winning out. Several interacting factors significantly hampered the process.

Temperature Fluctuations

Consistently sub-freezing temperatures were the primary culprit in hindering the snow melt. The cold snap persisted for an extended period, with daily lows well below the historical averages for this time of year. This prolonged freezing significantly impacted the rate of daytime melting.

• Daily temperature lows: For several consecutive days, temperatures remained below 20°F (-7°C), preventing any substantial melting.
• Comparison to historical averages: This cold snap was significantly colder and longer-lasting than typical winter events in Tulsa, leading to an unprecedented delay in snow melt.
• Impact of nighttime freezing on daytime melting: Even when daytime temperatures climbed slightly above freezing, the overnight refreezing negated much of the progress made during the day.

Sunshine and Sunlight Duration

Sunlight plays a vital role in accelerating snow melt. However, the period following the winter storm Tulsa experienced saw limited sunshine. Cloudy days and the naturally shorter daylight hours during winter further slowed the melting process.

• Number of sunny days following the storm: The number of sunny days immediately following the storm were minimal, reducing the amount of solar radiation available to melt the snow.
• Cloud cover percentages: High cloud cover percentages further reduced the impact of the limited sunlight.
• Duration of sunlight each day: The shorter daylight hours during winter, combined with cloud cover, significantly reduced the overall energy available for snow melt.

Wind Conditions

Wind speed and direction also impact snow melt rates. While wind can help accelerate melting by removing the insulating layer of snow, the wind during this period wasn’t strong enough to offset the effect of low temperatures. In fact, the wind chill factor further decreased the effective temperature.

• Average wind speed during the period: While some days saw moderate winds, the average wind speed was insufficient to significantly influence the snow melt.
• Prevailing wind directions: The prevailing wind direction didn’t contribute to significantly faster melt in specific areas of the city.
• Impact of wind on exposed surfaces: While wind did impact exposed surfaces, its effect was minimal compared to the influence of temperature and sunlight.

Ground Composition and Snowpack Density

The type of ground surface significantly impacts snow melt rates. Furthermore, the density of the snowpack itself plays a crucial role. A dense, compacted snowpack acts as an insulator, slowing down the melting process.

• Comparison of melt rates in different areas: Snow melted faster on paved surfaces compared to grassy areas due to differences in heat absorption and retention.
• Discussion of compaction and insulation effects of dense snow: The heavy snowfall resulted in a dense snowpack, which acted as an insulator, slowing down the melt rate.

Consequences of Delayed Snow Melt in Tulsa

The delayed snow melt had numerous negative consequences across the city of Tulsa.

Traffic and Transportation

Icy roads created significant challenges for traffic and transportation. The prolonged period of sub-freezing temperatures exacerbated the situation, making road conditions hazardous and hindering snow removal efforts.

• Road closures: Numerous roads were closed due to icy conditions, disrupting traffic flow.
• Traffic accidents: The hazardous road conditions led to a significant increase in traffic accidents.
• Delays in public transportation: Buses and other forms of public transportation experienced delays or cancellations due to icy roads.
• Impact on commuting: Commuting times were significantly increased for those who still attempted to travel during the cold snap.

Potential for Flooding

Once temperatures finally rose above freezing, the rapid melting of the accumulated snow posed a significant risk of localized flooding.

• Areas at higher risk: Low-lying areas and areas with poor drainage were most at risk of flooding.
• Potential drainage issues: Clogged storm drains and inadequate drainage systems exacerbated the risk of flooding.
• Impact on basements and low-lying areas: Basements and other low-lying areas were particularly vulnerable to flooding damage.

Impact on Businesses and the Economy

The prolonged cold snap and delayed snow melt had a significant negative impact on local businesses and the overall economy.

• Business closures: Many businesses were forced to close temporarily due to the hazardous conditions.
• Supply chain disruptions: Transportation difficulties disrupted supply chains, affecting businesses reliant on timely deliveries.
• Lost revenue: Businesses experienced significant losses in revenue due to closures and reduced customer traffic.
• Employee absenteeism: The hazardous conditions led to increased employee absenteeism.

Understanding Tulsa's Snow Melt Challenges After a Record Cold Snap

The delayed Tulsa snow melt following the record cold snap was a complex event influenced by a combination of factors including persistently low temperatures, limited sunlight, insufficient wind to disperse the snow, and the insulating effect of a dense snowpack. The consequences were significant, impacting traffic, posing a flood risk, and negatively affecting the local economy. Understanding these factors is crucial for improving preparedness and response strategies for future extreme weather events in Tulsa. Stay prepared for future Tulsa snow melts by monitoring weather forecasts closely, clearing snow and ice promptly from your property, and having an emergency plan in place.
