00:00We are in southern Illinois where a PBS tornado watch is in effect. That's a
00:04particularly dangerous situation but so far supercells have not yet matured. There
00:09is a capping inversion in place and an outflow boundary across southern
00:13Illinois but we're starting to see convective towers begin to form here
00:16across southern Illinois. Those have the potential of maturing into supercells
00:20over the next one to two hours and any of those supercells that are able to
00:24mature will be capable of producing strong to intense tornadoes through the
00:29evening. That includes southern Illinois into southern Indiana portions of western
00:33Kentucky and some of the forecast models are even showing supercells developing
00:37further south down near Memphis and even Little Rock but initiation is a little
00:41bit more uncertain out there. You can see the low clouds racing from south to north
00:46down here. That's the low-level jet and we also have a lot of instability. The
00:50temperature is about 82 degrees, dew point 71, so there's extreme instability out
00:54here. Low cloud bases, strong low-level wind shear, and certainly a chance of a few
01:00strong to potentially intense tornadoes. It's a very volatile environment but it
01:04does depend on a supercell maturing in this environment for a tornado to happen.
01:09Definitely stay tuned to those severe weather watches and warnings as a large-scale
01:13severe weather outbreak is underway from Arkansas all the way up through Illinois
01:17and Indiana.
