Derecho With 100 mph Winds and 3" Hail...

By -
Update  10:40pm, the cluster of thunderstorms which comprise the derecho as constricted in north-south extent with the resulting strongest winds near the KS-OK border. See below:
Peak winds near the arrow will be around 70 mph with less strong gusts as you move away from it in the north or south directions. 

I do not think Tulsa will receive damaging winds overnight. 

----------------------
...in addition, a "couple of tornadoes" are forecast to occur.
This severe thunderstorm watch is in effect until 2am CDT.  This is a highly dangerous situation.
  • If friends or family live in a mobile home, call them and suggest they spend the night. 
  • Power failures are likely. I urge you to prepare. 
  • Trees will likely fall, If you have a chain saw fill it with fuel. Fill your car with fuel (pumps and chargers don't work) in advance of losing power. 
  • Get a few extra dollars at the ATM. Cash is valuable when card-readers don't work.
  • Make sure the children are aware.
  • Pick any ripe tomatoes. 
Please monitor local weather information the rest of the evening if you live in these areas. 

Update 7:47pm:  A wind gust of 114 mph was measured in the eastern Oklahoma Panhandle.

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
