Understanding Winter Weather in North Texas
Snow in North Texas isn’t unheard of, but it’s just uncommon enough that all eyes are on the forecast when there’s a chance of flurries. Frozen precipitation isn’t expected any time soon, with above-normal temperatures expected through Christmas Day. But as we dream of snowflakes, here’s a refresher on the exact conditions the atmosphere needs to turn Dallas-Fort Worth into a winter wonderland.
Introduction to Winter Precipitation
Winter precipitation comes in several forms, including snow, sleet, and freezing rain. Each type of precipitation has its own unique characteristics and requirements for formation. Understanding these differences is key to predicting and preparing for winter weather in North Texas.
Snow
Most winter precipitation starts out as snow, since it’s usually cold enough at the top layer of the cloud to create snowflakes, the National Severe Storm Laboratory said. Whether it stays snow depends on whether the temperature is consistently below freezing from the cloud all the way to the ground.
Snowflakes, which are collections of ice crystals, are considered flurries when only a small amount falls in a brief period. They usually do not stick to the ground or only create a light dusting.
Blowing snow is snow driven by strong winds that can significantly reduce visibility. It may be snow that is actively falling, or loose snow on the ground picked up by the wind.
Sleet
Sleet forms when falling snow hits a shallow, warmer pocket of air and partially melts. Those slushy drops then pass through a thick layer of freezing air and refreeze as sleet. It can bounce on impact.

Freezing Rain
Similar to sleet, freezing rain starts out as snowflakes in the cloud. As it descends to the ground, the precipitation passes through a thicker layer of warm air and melts completely. These raindrops then pass through another brief layer of freezing air before making contact with trees, roads and power lines. If the object it makes contact with is below 32 degrees, the water refreezes upon contact and can coat objects in a layer of ice.
A significant accumulation of freezing rain, usually at least a quarter of an inch, is considered an ice storm.
Conclusion
In conclusion, winter precipitation in North Texas can take many forms, including snow, sleet, and freezing rain. Understanding the conditions necessary for each type of precipitation to form can help residents prepare for and respond to winter weather events. By staying informed and up-to-date on the latest forecast, individuals can stay safe and minimize the impact of winter weather on their daily lives.
Frequently Asked Questions
What is the difference between snow and sleet?
Snow and sleet are both forms of winter precipitation, but they have some key differences. Snow forms when the air is cold enough for snowflakes to form and remain frozen all the way to the ground. Sleet, on the other hand, forms when snowflakes fall through a layer of warm air and melt, then refreeze into ice pellets before reaching the ground.
What is freezing rain?
Freezing rain is a type of winter precipitation that forms when snowflakes fall through a layer of warm air and melt, then pass through a layer of cold air before reaching the ground. If the ground temperature is below freezing, the raindrops will freeze upon contact, forming a layer of ice.
How can I prepare for winter weather in North Texas?
To prepare for winter weather in North Texas, it’s essential to stay informed about the latest forecast and weather conditions. Make sure you have a winter emergency kit with supplies such as food, water, and blankets, and consider investing in a snow shovel and ice melt. It’s also a good idea to have a plan in place in case you lose power or heat during a winter storm.
