Accumulating Snow Just Misses Stateline
Temperatures will be falling this week, but there still aren't any major snow falls in the forecast for the Stateline area.
A deep low pressure system currently in the Rockies will head east today, moving into the Plains this afternoon, before arriving overhead Wednesday afternoon. The heaviest of the snow will fall just to the north of the low pressure track, and this will drop high accumulations across South Dakota, Nebraska, northern Iowa and into western Wisconsin. Snow could pile up over 10" in northwestern Iowa, and 4-7" inches of shovel-able snow for western Wisconsin. Winter Storm Warnings and Winter Weather Advisories have been issued ahead of this storm already.
Closer to home, 1-3" will be possible near Madison, and near 1" is a good bet in southern Wisconsin. Green County in Wisconsin is the only Stateline county that has a Winter Weather Advisory issued for it. It will go into effect at 6pm Tuesday night and will expire at 6pm Wednesday. Northern Illinois will recieve just minor accumulations, near quarter inch by Wednesday.
But first, light rain will arrive around dinner time tonight, and will then mix with light snow overnight tonight as temperatures fall into the low 30's. Little to no accumulation expected by tomorrow morning. Light drizzle is possible Wednesday morning before another rain/snow mix arrives tomorrow afternoon, transitioning to all light snow Wednesday night. Again by Wednesday evening, around a half inch of snow will be possible by Wednesday evening.
The rest of the week features scattered flurry chances, with high temperatures stuck in the upper 20's through the weekend.
