- Winter Storm Warning through Saturday
- Heavy snowfall is expected
- There could be near-storm conditions on Friday
MADISON, Wis. (WMTV) – Our big winter storm is just starting to wreak havoc on southern Wisconsin and much of the north-central part of the country. The first days of the weather warning will remain in effect until Saturday. Overnight snowfall has brought snowy and slippery roads this morning. The snow is expected to continue into the afternoon before softening and ending for a period of this evening.
Accumulations will be in the 4–7 inch range for much of southern Wisconsin by the time all is said and done. The lowest amounts will be south and east of Madison. Locally up to 8 inches will be possible north and west of Madison. A winter storm warning is in effect for all of southern Wisconsin until early Saturday. This will be a long lasting winter storm with many elements to contend with.
Until the snow ends, the wind will pick up and gusts of 40-50 mph are expected tonight, Friday and Friday night. The wind will continue to be strong in the early hours of Saturday, but is expected to decrease steadily throughout the day. This will create potentially life-threatening conditions.
Bitterly cold temperatures will settle in the storm’s wake. With strong winds, wind chills can reach -40 degrees. Stranded travelers may be at high risk of life-threatening conditions.
Steady, moderate to heavy snow is likely through midday before clearing through the afternoon and evening. Temperatures will drop from the 20s to the twenties and into the single digits by late evening. Winds will be out of the northwest at 10-20 mph through the afternoon and evening. Roads are expected to deteriorate throughout the day.
Periods of light snow will reduce to flurries as we move into the night. The biggest story will be the strong winds that will develop from the northwest 30-40 mph. Blowing and drifting snow will become a problem with travel becoming very difficult to impossible at times. Overnight lows will be in the single digits below zero with wind chill values as low as -40 degrees. This dangerously cold condition will continue into Friday morning with freezing possible in 10 minutes or less.
We will likely start the day dry with scattered snow showers developing during the afternoon and evening. Don’t be fooled by the fact that there may not be much snow. Strong winds of 30-50 mph will continue through Friday creating significant blowing and drifting snow. Travel is discouraged and may be impossible as some of the worst storm conditions are breaking through. The wind chill will remain around -20 degrees throughout the day.
Not much improvement as we move into the overnight hours as snow showers remain possible. While additional accumulation will be light, winds will continue to gust 30-40 mph with blowing and drifting snow. Wind chill values will also be around -30 degrees creating dangerous conditions.
Saturday will start messy with difficult trips. The wind will continue to blow at a speed of up to 30 km/h. This will lead to continued blowing and drifting of the snow. While the ride will be rough early, there should be a slight improvement later in the day. Temperatures will be in the single digits with wind chills of -20 to -30.
The winds begin to calm and the worst of the storm will pass. Driving will still be tough and it will still be very cold with sub-zero lows and double-digit sub-zero wind chills.
Mostly sunny and calm conditions return. Still cold as the maximum will only be in the single digits and wind chill values below zero. Southern Wisconsin will begin digging out and cleaning up from a major winter storm as roads improve.
