2-6-18 Daily Blog: Sleet, Freezing Rain & Snow Arrives Tonight; Winter Weather Advisory in Effect
An wintry mess is headed to the region tonight. Winter Weather Advisories have been hoisted for much of the area, as you can see from the map below.
Latest hi-res data brings the wintry mess into SW Indiana by 7pm tonight. The mess will then overtake the area over the next few hours. This will be a late evening and overnight event. I noted yesterday that we could see some of this fall more as sleet than as freezing rain, even though the data yesterday did not show it. Latest trends in the hi-res data do indeed show that sleet potential. You see it on the loop below showing up in purple, with freezing rain in pink.
The latest data makes me question just how much the icy mess will go into Kentucky. I’ve updated my SnowCast map below to reflect the trends. This will be a pretty narrow band of ice and it looks to hover right along the Ohio River and counties above it mainly. Due to uncertainty, I’ve included counties below it as well. But my gut says this will probably be more of an Indiana ice threat than Kentucky. Time will tell. I think we could see up to a half inch of sleet and up to a quarter inch of freezing rain in the areas that get the icy mess. Snow would be pretty limited in those areas, maybe a half inch to an inch at best – and some of that icy area might not get any snow out of this. A bit more to the north, expect 1 to 3 inches of snow in the blue area. Some sleet may mix into that area the further south you go, as well.
Any way you cut it, portions of the area are going to have a pretty nasty commute on Wednesday morning. Roads will start to deteriorate as this rolls in late this evening. Again, after 7pm in SW Indiana and then quickly spreading over the rest of the state over the next two hours.
