Flash Flood Risk Tonight

By -
Flash flood conditions are in progress in Colorado to the south of Denver. They will worsen for at least the next three hours (10:30pm MDT). Please keep up with local weather information. 

After 11pm, I expect thunderstorms with heavy rain to develop in the red area of western Missouri below. There is a chance of heavy rains in the green area.
It would not surprise me for 6 to 8 inches of rain to fall in a spot or two. If this is correct, it will cause significant flash flooding. If you live in a low or flood-prone area, please take your smartphone to bed. 

Update:
Here is the rainfall that fell up to 8am. 

And, it is still raining in Missouri as of 9:14am.

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
