More on the tropical torm an its possible influences on our weather:
Thank the Lord I moved to Leeds...I left the washing out this morning.And the flapping of the butterflie's wings in Hong Kong caused a typhoon in Wakefield ...

That's a pity, Johnny - it's been lovely here this past couple of days. I think you may see something of an Indian Summer this year to balance-out the bad rub of the green so far this summer.Thankies Chris, we've still got the driving rain and high winds, though thankfully no tornadoes.( as yet ).

Synopsis
An upper trough axis lies SW to NE across the far NE Atlantic and a cut-off upper low sits over Iberia to the west of an upper ridge over central, southern and eastern Europe. At the surface, a weak cold front will slide slowly SE across England and Wales, with a warm and huimid airmass across SE UK and an unstable showery flow across NW UK. A shallow area of low pressure covers the near continent which will deepen slightly and bring an area of heavy and perhaps thundery rain across SE UK tonight.
... SE UK ...
The NW edge of a plume of very warm and humid airmass residing on the near continent will sit across SE England today and overnight. Isolated elevated heavy showers, perhaps with sporadic lightning, may occur where Ac cas becomes deep enough with subtle forcing along NW edge of plume. Otherwise, overnight there is an increasing risk of embedded elevated thunderstorms within pulses of heavy rain developing and moving NE from N France / East English Channel across SE England ... as baroclinic zone and surface convergence developing over northern France in response to falling heights/temps from the NW create increased ascent of plume over near continent. There is a risk of minor localised flooding from these storms, mainly Sussex and Kent overnight.
... N. IRELAND and W SCOTLAND ...
With steepening lapse rates from the NW, as upper trough / cold pool slides SE, convection may become deep enough amongst the showers expected here to produce sporadic lightning and small hail.
