Derecho Tonight?

A derecho is a long-lived storm complex that can produce damaging winds, large hail, and occasional tornadoes for hundreds of miles. There are some indications that one might form tonight.
AccuWeather regional radar shows a strong complex of storms over southeast Kansas moving east. There has already been one report of 70 mph and a second report of 60 mph from those storms in the southwest part of Kansas. Scattered thunderstorms are developing south of Kansas City and north of Oklahoma City in the very unstable air over the area along and east of I-35.

Computer guidance shows the statistical chance of derecho forming in 3-4 hours is fairly high. If that occurs, damaging winds and hail are possible. So, I'd put the car in the garage if you are in the area outlined below and bring in lawn furniture and things that can be easily blown about.
I'll blog about this at least one more time this evening.
