Winter Storm Outlook -- Updated 4:45pm

By -
It is looking like a winter storm will be developing over the northern Great Plains over the weekend. 


Sunday and Sunday Night
At lower left is the probability of 4" or more of snow. It is also possible there will be strong winds with this storm. So, I recommend those traveling on I-90 and, especially, I-94 begin looking at alternate routes. Note also the high probability of heavy snow over the Sierra. 

Monday and Monday Night
With Monday's snow, preliminarily, amounts may be high over parts of Minnesota and the eastern Dakotas. Again, consider the possibility of re-routing a road trip. If you are planning to fly through Minneapolis, you may wish to consider a re-route through Northwest's Detroit hub, if possible. 

Update 4:45pm: The National Weather Service is also raising the alarm.

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.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. 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. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue is 0.1 to .25 inc
