Lake effect snow is likely Wednesday into early Thursday across parts of NE IL and NW IN.
After a warm start to the week including temperatures pushing to near 50 in these areas on Tuesday, a cold front will move southward Tuesday night. Cold temperatures, strong northerly winds and favorable surface convergence will lead to a healthy lake effect snow band development. Amounts will be difficult to forecast as always with LES but a narrow corridor of 6+ inches appears possible especially near NW IN.
Also of note will be the potential for blizzard conditions near the I 65, I 94 and I 90 corridors. Wind gusts could be in the 40 to 50 mph range according to the latest run of the Euro. This would definitely cause significant impacts to travel and lower visibility in this localized area.
