Impressive Plains Severe Weather

I was a little caught off-guard* by the severity of the weather in the Plains tonight. It's been so long since we've even had a Moderate Risk, but the government slipped in a tiny one this afternoon while I wasn't looking. Sure enough, impressive storms are occurring in northern Texas, Kansas and Nebraska.
Truth be told, there are Severe Thunderstorm Watches out from Mexico to Canada tonight.

I have uploaded a number of radar captures and images from AccuWeather.com RadarPlus to this location, and will again later tonight if conditions warrant. (On that site, "a" denotes regular radar, "v" velocity, "s" storm-relative velocity, and "z" zoom).

At 5:25 p.m. Eastern time, the WeatherMatrix StormMatrix, which tracks nationwide storms as detected by NEXRAD radar, reported 5 Tornadic Vortex Signatures and 5 storms with hail more than 4 inches in diameter (softball size)! Either is rare, both together are very impressive. Here's what it looked like, for the record.

In the spotter reports that the StormMatrix analyzes, the most impressive category today is the wind reports. There have been 7 reports of wind over 80 mph (the highest 88 mph near Stonington, Colorado) and 18 reports over 70 mph (mostly in Texas and Kansas), all in less than two hours this evening. This is quite unusual, especially without a widespread area of Moderate Risk.

At least one, maybe two tornadoes have been reported in Kansas, one from the National Weather Service office in Goodland. Thus far, only hail to 2.75" in diameter has been reported by spotters.

RADARPLUS SHOWS STORMS, LIGHTNING AT 7 PM

*As you can see by the map below, which was made at 4 a.m. this morning, clearly the "real" forecasters saw this coming :)
