The first image shown is a GFS weather model depiction of a possible scenario by noon this Sunday- showing the 850 millibar 0° Celsius (32°F)temperature line just south of Kansas City- with the green shading indicating the precipitation that may begin as early as midnight Sunday morning.
That precipitation- which could be freezing rain- sleet and/or snow is forecast to continue into next Monday.
This could well mean Metro K.C. is in for our heaviest snow yet this Winter of 2010-11.
By midweek- much-below average temperatures will overspread the entire Central States and by late week- the 0° Celsius (32°F)temperature line shows on the GFS model (2nd image) to be south of the Texas Gulf coast.
Of course as any weather enthusiast knows- "new data is in" all the time- so the forecast could improve as we get closer to the weekend or it could get worse.
