From the National Weather Service in Paducah:

Scattered freezing rain is expected to develop late Tuesday night and overspread the rest of the Quad State region on Wednesday. The freezing rain will become more widespread late Wednesday into Thursday. Although minor snow and sleet accumulations, less than an half inch, are possible, the main concern will be ice accumulating due to the freezing rain. Travel, especially on untreated roads and bridges, will become hazardous with time, especially during morning and evening commutes. Where the highest ice accumulation and stronger winds occur, scattered power outages and some tree damage will be possible.

Important Forecast Changes:

Given the strong push of Arctic air into the region, the focus of the higher ice accumulations has shifted south into southern sections of southeast Missouri, west Kentucky, and extreme southern Illinois,

Winter Weather Quick Facts and Preparedness:

Quick facts you should know about winter weather:

  • Snow can occur at temperatures as high as 46 degrees if conditions are right.
  • The record for most snowfall in the Lower 48 in a 24 hour period is 75.8” at Silver Lake, Colorado in 1921.
  • Blizzard conditions are met when visibility in falling and blowing snow reaches ¼ mile or less and sustained wind speeds of 35 mph or greater occur for 3 hours or more.
  • As little as 1/16” of ice can begin to impact roadways and sidewalks.
  • As the wind increases, the body is cooled at a faster rate. The “wind chill” is a way for meteorologists to communicate what the combination of wind and temperature “feels like” to exposed skin.

Preparedness:

– A Winter Storm Watch is issued when conditions are favorable for significant winter weather and/or blizzard conditions. Time to prepare!

– A Winter Storm Warning is issued when a combination of heavy snow, blowing snow, and possibly ice mixed with snow is expected to impact the area. Time to act!

– A Blizzard Warning is issued when the combination of strong wind, low visibility, and heavy snow will significantly impact daily life.
