Severe Storms on March 6-7, 2017
 
The satellite showed a line of thunderstorms approaching Arkansas from the northwest during the late evening of 03/06/2017. Ahead of the line, isolated supercells (storms with rotating updrafts) developed mainly in northern and western sections of the state.

March came in like a lion on the 1st (a round of severe weather in northern Arkansas), and continued roaring on the 6th/7th. A new cold front was set to push into the region from the north, and it was accompanied by a line of thunderstorms.

 

The WSR-88D (Doppler Weather Radar) confirmed what satellite was showing, with discrete storms popping up ahead of an incoming line of storms during the late evening of 03/06/2017.

The line promised strong to damaging winds, but there was more to worry about. Isolated storms ahead of the line were expected to show signs of rotation, and possibly spawn tornadoes.

 

At North Little Rock (Pulaski County), winds changed direction with height (going from south or 180 degrees to southwest or 235 degrees) at 600 pm CST on 03/06/2017. Winds also increased with height (going from less than 10 knots near the ground to 50 knots at 1.5 km and 3.0 km aloft). This resulted in a curved hodograph (red line), which is a signature that makes tornadoes a concern (assuming strong/severe thunderstorms are expected).

Hodographs (a diagram representing the magnitude and direction of a moving object) revealed winds turning with height and becoming strong, which helped support rotation.

A WSR-88D (Doppler Weather Radar) showed a lone supercell (storm with rotating updrafts) northwest of Marshall (Searcy County) at 1220 am CST on 03/07/2017. The storm was just ahead of a line of showers and storms surging through Berryville (Carroll County) and Huntsville (Madison County).

During the late evening of the 6th, a supercell (storm with rotating updrafts) produced a tornado (rated EF1) near Crosses (Madison County). This was confirmed by the National Weather Service in Tulsa, OK. As the storm tracked through areas farther east, yet another tornado resulted.

 

This long track tornado (almost 37 miles) ripped through Newton and Searcy Counties, and was rated EF2 by the National Weather Service in Little Rock, AR.

A long track tornado (rated EF2) affected portions of Newton and Searcy Counties on March 6-7, 2017.
