Clark County commuters should be prepared for a difficult commute on Wednesday morning. Make sure you have fuel, traction devices, and other emergency supplies in your car. Also, leave plenty of extra time to allow for safe, slow driving. You don't want to be in a rush.
The National Weather Service says that a heavy band of moisture will enter the area tonight over the very cold air in place now. This could result in snow accumulation of 1-3 inches down to the lowest elevations. Most precipitation would fall between midnight tonight and 8 AM Wednesday, which is perfectly timed to interfere with the morning commute.
It is difficult to predict the specific time and location of the transition from snow to rain. It's possible that any snowfall would primarily be to the north and at higher elevations. However, drivers should be prepared for accumulating snow at low elevations.
