The National Weather Service has issued a WINTER STORM WATCH for most of the Big Country and Heartland from 12:00 p.m. Wednesday through 6:00 p.m. Thursday. Knox County is under a WINTER STORM WARNING from 9:00 p.m. Tuesday through 6:00 p.m. Thursday. Significant impacts from a winter storm are possible during this time. Wintry mixed precipitation may become heavy during this time causing hazardous conditions for travel. It will become dangerously cold at times. Wind chill values may drop to as low as -10°F. Exposure in temperatures this low will cause a risk of frost bite and even hypothermia.  

Here is a rough timeline of what you can expect…..

Gusty north winds behind a Tuesday evening cold front will usher in a noteworthy arctic air mass. This will be the coldest air of the winter season so far. Rain chances will move in daybreak Wednesday. Precipitation chances will increase during the afternoon. High temperatures on Wednesday will be reached around noon. Most areas will only get into the low 40s. Temperatures will fall to around freezing during the afternoon hours. The drive home from school and work Wednesday afternoon/evening has the potential to become hazardous as the rain changes to freezing rain and sleet. A light glaze of ice may form on outdoor surfaces, including tree branches and power lines, from any freezing rain. This along with gusty north winds will introduce a power outage threat. 

A change to all snow is expected Wednesday night into Thursday morning as temperatures plummet to the low teens. Wind chill values will be as low as -10° during this time. These temperatures are dangerous. Exposure in this type of weather will cause a risk of frost bite and even hypothermia.  This chance of snow will continue through the morning and may even linger into the afternoon. Snow accumulations look to be around 2″-5″ for most people. There may even be some higher totals across the Northern Big Country. Hazardous traveling conditions and dangerously cold temperatures will continue through Thursday. High temperatures will only reach the low 20s. A breezy north wind will make it feel around 10° colder. 

Road conditions will likely suffer through Friday morning as temperatures will stay well below freezing. Friday morning will see single digit temperatures. Afternoon highs will approach the freezing mark with bright sunshine. There will be some melting Friday afternoon, however any leftover moisture will freeze over again Friday night. Temperatures will reach the 40s by Saturday afternoon putting an end to hazardous travel. 

How to prepare…..

It is a good idea to have plenty of food and water to avoid any unnecessary trips to the store. Also, make sure to have plenty of gas for generators and vehicles. Keep in mind the plants, pets, and pipes.
