I have been waiting for the 6Z to say this.
For all those worrying about shower activity: the LI (a measure of the instability in the air)is on a nosedive from now on which enables the convective available potential energy (CAPE) to be released this afternoon. By 20:00 I have 1080 J/kG of CAPE and an LI of -5! I cannot emphasise enough how rare it is the sea figures so high in winter. If we do not see some substantial showers with lightning activity by 4 PM, then I am a chocolate frog!
