National Weather Service forecasters have kept a wary eye on the several ingredients required to fuel a weekend severe weather outbreak across Wisconsin for several days now, and little variation has evolved from original forecast models.
High winds had already prompted an advisory through 4 p.m. on Saturday, but the focus remained on the risk of a frontal system setting off rounds of severe thunderstorms.
The Bottom Line: The threat of severe weather will be greatest between 7 and 11 p.m. today, but could begin to our west as soon as 4 p.m. Possible large hail and damaging winds remain the biggest concern, although forecasters couldn’t rule out a tornado or two either as a cold front moves through after 6 p.m. As that front returns north as a warm front on Sunday evening, the stage will be set for the chance for more high winds and hail.
Rainfall for the duration of the event – from Saturday afternoon through Monday – could be anywhere from one-quarter, to an inch-and-a-half of rain, depending upon how individual cells and lines of storms behave. The odds of localized flooding, however, are low at around 15% for the Sheboygan Area.
After a cool-down on Sunday the week that follows is, so far, expected to be mild, with highs mostly in the 60s and lows near 50. And as is typical of spring in this area, rain showers can’t be ruled out.
