Weather Radar Map: High Speed Object Appears To Enter A "Vortex/Portal" In The Sky Over Long Valley

There was an incredible amount of lightning in the Long Valley on August 28, 2019, 9.45 pm, when a strange vortex/portal appeared on the weather radar map just above Long Valley.


Next, an anomaly came out of nowhere, entered and flew through the vortex/portal at a very high rate of speed on which then the vortex/portal disappeared.

According to MrMB333 the anomaly covered a distance of 60 miles in 20 minutes which is about 180 mph.

So, it looks like a portal opened up and something went through it, but what could it have been?
