November 28, 2019 – Washington Co., WI – Signed up with an agency called TrueWeather, thanks to Aron Rodman at Extra Mile Snow Plowing.
Let’s check in and see what the Event Synopsis is for the next few hours:
A few pockets of moisture will move through the region overnight. Most will likely see a few flurries with no impacts. However, if the moisture falls as mist or a period of drizzle this could lead to a few slick spots on untreated surfaces. The mist/drizzle is about a 15-20% chance.
The latest high resolution guidance is showing a few areas of lift within the clouds tonight. If the upper level lift is dominant only a few flurries are expected with little to no impact. However, if the lower level lift is dominant we could see a mist or drizzle develop producing a light glaze of ice. This is about 20% of occurring. We will monitor throughout the evening. Simulated radar shows the isolated nature of this activity through the morning.
A brief period of snow is possible before changing to rain. A changeover back to snow is expected on Sunday with minor accumulations possible mainly on non-paved surfaces with a refreeze threat Sunday evening.
Another trough is expected to move through the area on Sunday. Current model forecasts have the system developing over Colorado, before moving into Nebraska, and over Iowa. Due to the location of the low pressure system, this region will be in the area that typically receives rain changing to snow. Short-mid range forecast models have varying snowfall amounts at this time, but as the event draws closer, those ranges will narrow. The image shows the latest European model snowfall accumulation through Sunday keeping the swath of heavier snow to the north.
