11pm EST Winter Storm Update

By -
Very heavy snow has moved from Evanston to downtown Chicago and many of the Lakefront areas (see radar). Heavy snow is also starting to develop around Bloomington (green shading). Some areas from the Loop to Gary will have as much as 6 to 12 inches.

There are multiple media reports that Delta has cancelled its flights to Washington Reagan and LaGuardia after noon to 1pm Eastern. Please check on your specific flight. Now that the cancellations have begun check this advice.

I just took a quick look at the latest data and forecasts have not changed a great deal. NYC (Manhattan) is likely to have 6 to 10 inches. Eastern Long Island a foot or a little more. A blizzard watch is in effect for Cape Cod. The pinks are winter storm warnings. The blues are travel advisories for snow (a lesser condition). Heavy snow is likely to be falling in the D.C. area Tuesday afternoon.

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
