Rain showers have overspread a number of locations in the area. Temperatures are still in the mid 30's throughout the area. While there will be a transition to snow overnight, any accumulation will more than likely be confined to grassy areas and car tops. It will be tough to accumulate on pavement following a day in the upper 40's. This could be overcome by high precipitation rates, which I am not seeing with this event. I am still pretty confident of a snowfall from 1-3" region wide.
In any case, the landscape should be white when you wake up in the morning. Another interesting feature with this event will be tomorrow night. Cold air will blast into the area tomorrow afternoon and evening. With it, there is a chance we will have a Nurlon trough pass through the region. The troughs usually produce and rather heavy period of precipitation. The neat thing is, they are only produced over a small area. Forecasting where these troughs set up are extremely tough and usually has to be nowcasted (as it happens). These are caused by clashing air masses which will be present tomorrow. In addition, the cold air, will drop temperatures well below freezing and cause any standing water or slush to freeze.
More to come as needed
