Updated Long-Range Tornado and Severe Thunderstorm Outlook

By -
Based on later data and model simulations, I've enlarged my potential tornado and severe thunderstorm* forecast. It is valid from noon Monday until 6am Thursday.
Just as a note: I am especially concerned about Tuesday in the central Great Plains. Based on preliminary indications, tornadoes with supercell thunderstorms may occur in parts of NE-KS-OK. 

There is also the potential of a severe blizzard in the Dakotas with blizzard conditions farther to the southwest. This should definitely factor into your travel plans. I will post a comprehensive blizzard outlook tomorrow.

Recommendations
Schools: If you haven't recently had a tornado drill, Monday tomorrow would be a good day. Make sure everyone is familiar with tornado procedures and ways to protecting everyone involved.

Business: See above, plus make sure you have ways of instantly notifying employees working outdoors. 

Homes: Make sure your shelter area is clean and ready to go. Put a couple of bottles of waters, old pairs of shoes (you don't want to walk out barefoot if a tornado strikes) and, if appropriate, a couple of diapers in your shelter. 

Everyone: Have at least two reliable ways to receive emergency storm warnings. One of them should be Wireless Emergency Alerts. 


*The definition of a "severe" thunderstorm is hail one inch or larger or 60 mph, or stronger, thunderstorm wind gusts.

Midnight: The East Coast Threat for Tornadoes and Severe  Thunderstorms Has Ended 3:50pm. Tornado watch for the Middle Atlantic Region. 2:30pm Tornadoes are also forecast in the South. 2:20pm. 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.

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 i...
