Ok--I have a question----What is a supercell? I know u know ur weather and my idea is probably wrong... But the cell I saw looked embedded in the main line. It is my understanding that a supercell occurs with storms isolated and out ahead of the main squall line. Am I correct? Does look impressive though either way.

This is an embedded and discrete supercell (producing very heavy thunder from a distance ... very forecful in nature) within the broad scale squall line ...

The thunderstorm is showing some rotation (note the bright red/green couplet close together on the 1.5 and 2.5 deg levels, indicating some ROTATION with the winds blowing away and towards the radar) ... The rotation is occurring (possibly a mid-level mesolow) ...

So at this point, the NWS would be monitoring it closely--the rotation--and if this continued, issue a tornado warning-correct?

Yes, if it becomes surface based enough ...

what i would be more concerned about is the funnel being rain-wrapped.

Exactly ... and the worst part, the thunderstorm just in the last minute is unloading a torrent of rain and lightning ... the Mesoscale Discussion and the new Tornado watch outlines the threat of rain-wrapped tornadoes ... NOT FUN...

with mid level rotating storms here in AZ is that they tend to be big hailers with strong winds rather than tornadic (and we do get a fair number of those types of storms here during the monsoon). You need to get that rotation to get lower in the storm and to tighten up before you get tornadoes.

Based on the 0.5 deg velocity, the rotation never made down ... all mid-level ... ironically, there wasn't hardly any wind with it, but torrential rains, and frequent lightning ...
