You would think that 2-3" hail with 40-60mph wind was likely with that big cell. It may have had a tornado near Linden TX, but I have heard no reports on that. It was a wide circulation.
There is a possible rain-wrapped tornado at Argo, TX. There is also a possibility that there is a tornado near Mt. Pleasant TX, or generally on the southwest side of these storms.
When the storm was near Groveton TX, the radar showed 60 dBz at 40,000. That must be a massive updraft and large hail. Radar-based hail estimations were up to 3.4"
Finally we are seeing some of the CAMs show storms in various areas of eastern Texas and Oklahoma. I was really wondering about that. Up until this morning, the models have been showing so much CAPE and so few storms. There should be wind convergence near the dryline.
As an interesting side note, it says there is an 80% chance of 10 or more severe hail events/ 80% chance of 1 or more 2" hail reports. Last Sunday, there were just a few hail reports in all of Mississippi, Alabama, and Georgia combined.
The USAF flyover did not quite go as planned. I drove down toward Eisenhower Blvd at 12:45. I was expecting to see the jets from 12:50 to 1:00. I finally gave up on it and came home. I heard some distant jets at 1:45.
3/15/2008 is a possible analog( listed as #3 analog) on CIPS (run: 4/17, 12z) I thought it was a better match to the low pressure area than the #1 analog. You better hope this storm report map doesn't happen. Interestingly the top analog is 4/6/82, a well-known blizzard from Chicago to Boston.
