Yes, if you have access you can see that's coming from the UKV.
Tomorrow looking a touch better on today. Subtle mid-level shortwave crossing the country through the afternoon and into the evening, which combined with light, converging low-level winds and diurnal max looks to support a break out of isolated to scattered heavy showers from late afternoon (as per recent mesoscale outputs), with the possibility of a few brief, weak storms with maximising of instability. A broad risk area (southern UK generally), though where winds converge and moisture pools the better chance of something firing.
