Craighead County Tornado Rated EF2

The above image is the estimated track of the tornado/funnel that went over Craighead county last week based on the damage surveys from the National Weather Service. (Click images to enlarge) The damage survey has been completed and I've mapped it out on Google Earth. It appears that the tornado touched down 4 times (not counting open fields). The first time it touched down and caused damage according to the survey from the National Weather Service was at 2:56 PM. This was on Highway 1 south of Jonesboro and caused EF 0 damage with peak winds at 75 mph. This is when the JPD officer first spotted it. Here's the survey:

The storm may have pulled up and then touched down just north of Bay. Thanks to the JPD officer, we knew the tornado was a threat at this point. If you missed my last blog post about this tornado, click here. The damage in Bay, AR occurred around 3:01 PM and it was the most extensive of this path and was rated EF2 with peak winds at 115 mph. I know we received one report of winds clocked at 113 mph from an aviation company to validate that rating. Here's the survey of this point from the National Weather Service:

At this point, there were several eyes on this storm and we had reports of it going up and down and radar showed the storm weakening. The last damage survey point was near Highway 18 between Black Oak and Monette. This survey also shows it was weakening and corresponds well with the report of it pulling up right on Hwy 18. Here's the final damage point from the National Weather Service. A rating of EF0 with peak winds at 75 mph.

One of the best things about this survey is that we had 0 injuries and 0 fatalities. I credit much of that to the JPD officer that spotted it when it first touched down south of Jonesboro. Ground reports are critical. Radar is great, but ground reports are so much better. The credible report from the officer was great, but we did not know about the report in the Storm Center until 3-4 minutes later. We are meeting with the E911 center tomorrow to establish better communication in the future. I'll keep you posted on that.


Have a great day!

PS- As some of you know, my wife has been in the hospital battling some respiratory issues. She's out and getting better. I'll be back to work tomorrow. Big thanks the the Poplar Bluff ER staff and the staff at AMMC!
