by Sarah ThomackSt. Joseph PostA Winter Weather Advisory will be in effect from midnight through 6 p.m. Friday.Meteorologist Dan Holiday says the winter storm is moving slower than previously anticipated and should hit the area early Friday morning.“It will start out with snow and then a wintry mix of freezing rain and sleet at times and that will probably stay with us through most of the day on Friday,” Holiday says. “But as temperatures get a little bit above freezing, we’ll see that transition over to rain and then it will kind of wind down once we get into Friday evening.”Holiday says the Friday morning commute will be affected.“On the way to work on Friday morning, you’ll certainly want to allow some extra time just because the precipitation may change over to different forms," Holiday says. "We may get sleet, we may get snow, we may get freezing rain at times, it could vary back and forth and because the temperature will likely be below freezing, it is going to create some slick road conditions.”The Missouri Department of Transportation says work crews will be out Thursday night treating ahead of the storm, but drivers should use caution as road conditions could deteriorate rapidly whenever freezing precipitation is falling.&nbsp;&nbsp; To check road conditions, go to MoDOT’s online <a href="http://traveler.modot.org/map/">Traveler Information Map</a>.
