Timing the Start of the Snow

By -
I'm starting to get questions about when the storm is going to start tomorrow morning in the southern Plains. Here is good estimate.

This shows, roughly, where snow is on the ground now:

This is the forecast of snow cover at 10am CST Christmas morning:
  • That is new snow in the High Plains with 2-4 inches along I-70 from about Oakley to Denver. 
  • U.S. 400 is forecast to have 2-4 inches of new snow from about Dodge City to the Colorado line.
  • Snow just starting along I-35 in northern Oklahoma. 
  • Conditions rapidly deteriorating by this time on U.S. 83 across Kansas and southwest Nebraska.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area.

Power outages may occur in this areas. Deep blue i...
