Another potential wave of severe storms

[Simone Lussardi]

... for southern China.

Jet has come back once again in this unusually hot year, this time seems even more energic than last time, from the W-SW, with a trough of low pressure positioned in the right place for severe weather around here:

That deep surface trough will deepen even more and move southeastward toward the coast, enanching the sfc flow tonight. In the back sfc westerly winds from the hot central continent will drive some convergence. Plenty of juice in place:

Some suspicious storm already bubbling:

Guys, by viewing intensively the sat loops and the maps (the sounding server doesn't work today... :? ) I'm afraid there're gonna be hard times for some places in China... :shock: Look at the trough and the strength of the upper level environment:

There might be the potential for some strong tornado tonight and tomorrow (excluding a break during night-time).

Situation complicates, the trough is pushing really hard in latest sats analysis:

Another aspect of interest. Note the blob of deep convection developed on the sea west of Taiwan. We got also a radar over there, here is it :shock:

That blob is even capable of degenerating into a tropical depression... Here's the radar loop:

On "type of plot", click on it and scroll down to Skew T. Then click on it. Then choose the number of the plot you want by looking at the map of China and clicking on that number. I tried it and got a nice Skew T. Plot. I think that is what you were asking for?

In fact the problem was that the data was unreachable, I really expressed it very badly above... , but now is ok Thanks anyway for your test !! From the sounding get what I suspected: an over 40 kts s.westerly flow at 500 hpa coming toward the coast with the sfc trough.
