Threat of Extended Flooding in the Midwest, Rockies and Great Plains

By -
Here is the latest from the National Weather Service:

But, the above map may be very conservative. This tweet came in at 7pm CDT.
This flooding in off the map in southwest South Dakota. All of this moisture and snow is present even before tomorrow's storm drops more heavy snow on the region.

Don't consider this information merely "interesting." If you live anywhere near a river,  I recommending you begin planning, perhaps by consulting your local emergency manager. Once these rivers begin flooding, they will stay above flood stage for a considerable period of time.

ADDITION: Just after I finished the above, the Governor of Nebraska issued a State of Emergency for Flooding for that state. [721p CST]

SECOND UPDATE: The snowpack in Breckenridge, Colorado, today as demonstrated by nephew Parker.
This at the base of the mountain with much more at the top. In addition, more very heavy snow will fall tonight through Wednesday night.

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...
