China3d... Videos of a new storm today...

[Simone Lussardi]

... or if is not a TVS, at least a very strong meso. Conditions are perfect for isolated strong/severe storms today, with plenty of shear, especially to the north of the region where there is a subtropical divergent jet stream passing by. I need to chase one of this cell sooner or later... :lol: :lol: :shock:

Here's the images and the loops:

Got a very quick development forming overhead, despite the darkness you can see the very low and turbulent cloud base. Lightning everywhere !

Update: the cell to my West continue to intensify and moves steadily east. Another line is forming, here now raining very hard but the radar signal almost nothing...

Very humid and warm now, dews around 26°C.

:wink:

Looking like that Western cell could be becoming supercellular... hopefully it stays descrete for you unlike that cell that developed nearly right on top of you...

 

[Andrew Pritchard]

Seriously, I'm moving to China. Im serious this time...this is ridiculous.

Great stuff Simone!

LOL! Ain't no ridgin' goin' on over there! I do belive nature is taunting us American chasers!

When all the boundaries that formed that day weakened all storms ended :lol: There was plenty of gasoline at the low level and after reviewing many times the radar I'e found that all storms were initiated by boundaries. The one I got overhead formed on a gust line descending from a strong cell from the north (velocity > 20 m/s, that's why it formed so quick...).

Today can be an even better day, with jet stream descending from the north.

Upper Jet is steadily descending in latitude from the north, and maybe this evening will be over southern Guangdong on this lake of gasoline:

I figured out to make the convective outlook for severe t-storms by myself :lol: :

Considering latest development in pressure pattern and satellite maybe the mdt could be extended a little southward later in the day. Overheating is spectacular, even too much.

Things are gonna get destabilized quite fast, also in the SLGT area, rock hard convection bubbling everywhere. Get this !!

Pressure dropping. Winds intensifiying from the E-SE now. Later I'll post the serious radar. The one posted is always the latest one.

:wink:

Wind storm now, gusts around 45 kts from the east, maybe an outflow boundary aided by new inflow..., shit I lost a tree in the garden :lol: :?

 

[Simone Lussardi]

A big one coming from the W-SW !!!! Wind still around 35 kts from the East !!!!

Videos !

Almost one CG every few seconds now. Gotta shut off all the factory, see you later ! :shock: :wink:

Back, this storm is gonna damage some place around here...

The storm has an RFD, that is now blowing here, not very strong, maybe 15/20 kts from the W-NW. Very nice to see just a few hundreds meters to the east flags blowing north, while here blowing south...

:wink:

 

[Simone Lussardi]

Geez, see he one exploding to the NW !

The other radar is out of service... :?

:wink:

 

[Simone Lussardi]

Another storm setting in from the W-NW !!! Many IC lightning now, mammatus well visibile despite is a bit dark. Dews steadily around 25. All radars out of service so I cannot see what's going on... :?

:wink:
