Weather impact: Green (No Impactful weather is expected)
Your NBC15 Weather Authority Forecast from Dylan Robichaud
Our next weather make will impact southeast Wisconsin on Sunday. An area of low-pressure, which is currently bringing severe weather to the Deep South, will work northward overnight tonight. As it makes the trek northward, it’ll bump into cold air. Forecast models are coming more into agreement on the arrival of precipitation. As of now, it looks as though light snow will start mid-morning across southeast Wisconsin and continue throughout the day. Snow accumulations will be limited to a dusting-1” on grassy surfaces due to surface temperatures being above freezing. This accumulation will take place mostly across Rock, Walworth, Kenosha, Racine, and Waukesha Counties. North and west of there, we’re looking at a dusting, at most.
Later in the week, a very strong and slow moving upper-level disturbance will strengthen across the Great Plains. This system will bring us prolonged rain chances which will start Wednesday and continue through the end of the week. Current forecast data indicated the possibility of several inches of rainfall.
Tonight: Mostly Cloudy. Winds North at 5-15 mph.
