Those of us who live around Atlanta, Georgia or Dallas, Texas, who only see around 2 or 3 inches of snow per year on average, can be heard complaining during the winter when a snow event occurs. There are, however, many cities around the nation where considerably more snow falls and it becomes part of the … Read more
Introduction This informative forecast writing will focus on the weather forecasting tools and concepts that are used to predict winter weather events. There are various types of winter weather events that are analyzed and forecasted including mid-latitude cyclones, ice storms, lake-effect snows and sleet storms. Each of these will be discussed separately. In addition, bust … Read more
Snow is a precipitation type that results from the build-up of ice deposition upon condensation nuclei. The snowflake size is amplified as ice crystals join together as the crystals move in the wind. A common theme in ice crystal development is the 6-sized structure of the ice crystals. The chemical bonding of ice molecules produces … Read more
The snow-to-liquid equivalent is the amount of liquid precipitation that is produced after melting snow. The temperature profile of the troposphere and the surface temperature are important factors that determine this value. The “average” snow-to-liquid ratio is 10:1. This is saying that if 10 inches of snow fell and that snow was melted it would … Read more
The “atmospheric river” is taking a direct aim on California, and that will result in eye-popping rainfall totals, heavy mountain snow accumulation, flooding, and mudslides. Weather conditions are ideal for an impressive and climatologically rare heavy-rain event over the weekend over a large section of California. Rainfall amounts from 8 to 12 inches are expected. … Read more
