It is imperative residents of the central Great Plains use the forecast to prepare for damaging winds and, perhaps, a tornado or two.  Tornado Risk The brown area has been moved south into northern Oklahoma and now includes Bartlesville, Ponca City, Enid, and Stillwater, in addition to the cities shown. In Missouri, it includes Joplin and Nevada.  Destructive Thunderstorm Winds Here is the color code: Pink and hatched: High  risk of destructive winds of 75 mph or stronger.  Red and hatched: Enhanced risk of wind gusts of 75 mph or stronger.  Yellow: Significant risk of winds 60 mph or stronger.  If you live in the red or pink areas, I urge  you to prepare for the potential for power outages, some could last a day or more. Bring in lawn furniture or trampolines which could blow about and crash into other objects -- increasing damage. Put your car in the garage or carport.

Radar Image and Commentary as of 10pm (This is the last of the hourly updates for this evening.) Radar image from 10pm. Note the explosion of pink/salmon color from southeast Oklahoma across southern Arkansas. The following (blue) was written at 9p: I am increasingly concerned about more freezing rain over the southeast half of Arkansas than is currently being forecast. If you live in southeast Arkansas, I recommend making ice storm preparations now.  Radar, plus ground truth data from Arkansas weather stations, show the icing concern is well-founded. There will be icing during the night in at least part of this area. 10:20pm Note: Some of the weather station's wind measuring instruments have already glazed over in southern Arkansas.  Thunderstorms with snow/sleet/freezing rain may occur in OK, AR, TX south of I-40. Ice Storm Warnings in Violet  Violet = ice storm warning (rare) Pink = winter storm warning  Purple = winter weather advisory  Dark Turquoise = wint...
