Chinook

We have had a couple of sub-severe storms out east of me today. The last 12 days have been above 60 here, with a high of 78, yesterday, a high of 81 on 4/27 and roughly 80 degrees today. Edit: the cold front has come in. In combination with some rain showers, the cold front has increased the dew point to 48 degrees. Summertime! Edit: my place has had some rain showers and distant thunder today.

I downloaded Nexrad level-2 data to make this 3-d image of the Moore tornado, 5/20/2013

Three possible tornadoes in southeast Oklahoma

High winds of 60-70mph have been reported west of Springfield MO, and also high winds detected by radar in this area.

Here is what I found for the MRMS calculated hail swath across DFW (one-hour only). Color bar is in millimeters, so 25mm = 1"

Is that from the MRMS web site?

I am pleased to announce that we will have a new thread for the summer. Today, it was 80 degrees here. The snow from several days ago is long gone. We probably will have above normal temperatures for several days. I hope we will have a summer with normal to above-normal rainfall.

Eastern Iowa could get several severe storms, with a chance for tornadoes. The SBCAPE may only reach 1000-1800 J/kg, which is generally kind of low, considering the SHARPpy-based soundings seem to have high CAPE numbers a lot of times.

Central to northeast Texas may have a loaded-gun type sounding, with 72 dew points, and some 850mb winds of 30-35 kt in some areas. This could be a situation for isolated or scattered severe storms that are slow-moving with just enough 0-6 km shear for mesocylones. Otherwise, I expect widespread storms from Missouri southward to Texarkana and possibly Oklahoma City. These storms may be facing a situation that the better 500 mb wind/ 0-6 km shear is trying to catch up to the storms, and/or catch up to the higher 0-3km SRH.

This was perhaps the best rotational velocity near Charlotte 10:30PM EDT (02:30z)

I guess this is the TDS for the confirmed tornado near Rome, TN. it's possible the tornado went over I-40

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.

Three updrafts near Okmulgee, OK. The north and south storms are roughly mirror images

I wonder if this was a QLCS waterspout at Carrabelle/ St Teresa

KJAX radar has shown reflectivity up to 78 dBz with hail up to 3.5". I think their radar is running a little hot.

There was a tornado report 4 mi southeast of Moultrie, and around Ellenton.

And just think, this used to be just a slight risk day that nobody was talking about.

I think the possible anticyclonic tornado moved into Effie or dissipated.

FCC = Federal Communications Commission.

Peachtree City?

If the tornado was continuously on the ground since south of Riverside TX, then 114 miles.

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"

A tornado may have occurred near Henderson

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.
