The winter storm arrived a little later than forecast, but the impacts will be significant tonight and for the rest of the week. Look at how extensive this massive storm is, based on all the winter alerts in effect as of Wednesday afternoon:
Let's start with the timeline. The big question now is "When will it end !". Our latest RPM model keeps us in snow through the afternoon:
By 10:00, the snow is still coming strong. Heavy accumulations are still highly likely over the entire Tri-State, especially western Kentucky.
By 2:00 a.m., the snow portion of the storm should be winding down as the system kicks off to the east:
Accumulations will vary widely from north to south, but the RPM is in line with our ongoing forecast of 6-10" across the Tri-State:
Temperatures will remain well below freezing through Friday. The snow pack on the ground will act as a refrigerator that will keep temps very cold. Over the weekend, warmer air will work in and temps should climb above freezing on Saturday and warm a little more each day through next week. Flooding will be a concern along area rivers with the rapid melt of the big snow. Here are the latest river forecasts:
The White and Wabash will rise, but not to flood levels.
