TRANSCRIPT OF AUDIO From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 25, 2019. MUSIC – ~ 7 sec This week, that excerpt of “Winter’s Fall,” by the Blacksburg- and Roanoke, Va.-based group No Strings Attached, opens an episode on the differences among three kinds of winter fall—that is, three kinds of frozen precipitation. We set the stage with some winter-storm mystery sounds. Have a listen for about 20 seconds see if you can guess what kind of falling frozen water you’re hearing. SOUNDS - ~18 sec If you guessed sleet, you’re right! You heard sleet falling in Blacksburg on February 17, along with a NOAA Weather Radio winter storm forecast for Southside Virginia on February 19. As the Weather Radio forecast shows, winter storms in Virginia can bring a hard-to-predict mix—some might say, mess—of snow, sleet, and freezing rain. What’s alike and what’s different among these three precipitation types? All typically start as snow high up in in the atmosphere, where collections of ice crystals combine into snowflakes. If those flakes encounter only sub-freezing air as they fall, they’ll reach the ground as snow. If, however, snowflakes encounter a warmer air mass on their way down, sleet or freezing rain can result. If that warm air mass is relatively narrow and more cold air is encountered below it, the melted flakes can refreeze and fall to the ground as pellets of sleet. On the other hand, if that warm air mass is wide and reaches relatively close to ground, cold, liquid raindrops can fall and, upon contact with surfaces at sub-freezing temperature, turn into coatings of ice—that’s freezing rain. Predicting whether a storm will result in snow, sleet, freezing rain, or just rain is complicated for forecasters, as shown by the Weather Radio forecast you heard earlier. And, of course, it’s crucial for public safety. Sleet may have relatively minor impacts, but we all know the challenges of snow, and significant accumulations of freezing rain—also called ice storms—can be especially hazardous from slick roads and downed trees and powerlines. Thanks to No Strings Attached for permission to use this week’s opening music. We close with some other music that sounds something like sleet, as its composer said, although the selection’s name isn’t what most people associate with sleet or freezing rain. Here’s a short part of “Pure Joy,” by Timothy Seaman of Williamsburg, Va. MUSIC – ~ 15 sec SHIP’S BELL Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.
