Winter Storm Denise set to bring variety of hazardsJanuary 29th, 2013 at 7:48 pm by phildecastro under News, Weather
Winter Storm Denise is knocking on our doorstep this evening. We’re already seeing the first signs of it in the form of some rain showers beginning to push in from the south. However, as we move through the overnight hours, it’s going to be more than just a snow-maker, as we could see hazards from Denise in several forms.
While the precipitation is going to start out as rain, it will gradually transition to sleet and then eventually all snow, likely sometime around or just after midnight, as colder air begins to surge into Northeast Wisconsin.
But this cold air is going to be compounding the problems we would have already seen from the snow alone. Warm air that was in place today, along with a soaking rain last night, has made road surfaces very wet. In some places, there’s standing slushy water sitting on the roads. Any sleet that falls would only add to the slushy mess. As temperatures drop tonight, that water on the roads and slush that’s piled up in some places could freeze solid, and freeze very quickly. Should that happen, it’s going to make an already hazardous situation even more dangerous as we start the day Wednesday.
On top of any ice that freezes, we’re expecting 5-8″ of snow accumulation late tonight and through the day tomorrow. Blowing snow could also be another factor as winds kick up tomorrow during the day.
As is usually the case, this Winter Storm is bring more than just snow to worry about.
