Extreme meteorologist Dr. Reed Timmer reports from near Show Low, Arizona, where he says there's even greater potential for severe weather than the damaging day before.
Transcript
00:00We have already chased a couple of tornado-warned supercells in the Show Low, Arizona area.
00:05They have been rolling off the White Mountains to the south of Show Low,
00:08where there are 8,000 to 11,000-foot peaks down there.
00:11And as soon as they exit the mountains, they lose steam a little bit.
00:15That first tornado-warned storm had a very low, bowl-shaped wall cloud on it.
00:19There's very strong, low-level wind shear to the north of the White Mountains
00:22with surface winds out of the southeast.
00:24There's about 3,000 capes out here with near 60 dew points and temperatures into the low 70s.
00:30That's more instability than yesterday.
00:32So there's likely even going to be a greater number of storms today.
00:35And there is a supercellular mode so far with this event.
00:38That is because of the bulk shear out here at 3,000 joules per kilogram surface-based cape.
00:44Dew points are near 60, temperatures in the low 70s to the north and to the south of the White
00:49Mountains.
00:50And that's contributing to even more instability than yesterday as well.
00:53These storms approaching the Show Low, Arizona area and St. John's have about 2 to 3-inch diameter hail already.
01:01There are big hailstones reported to the south of Flagstaff already as well.
01:05And this event is just getting started.
01:07We are going to continue off to the east chasing these supercells through the tornado watch area.
01:12Certainly stay tuned to those severe weather watches and warnings
01:15because the environment is prime for supercells with tornado potential.
