    GFS really quite shabby for Tuesday/Wednesday (showing brief thundery potential for EA during the morning). However, WRF-NMM much more optimistic in terms of MUCAPE flooding in from the SE...largely limited to the SE quarter. Also keen to break out convective precipitation with it. Assuming this is what the MetO is favouring in terms of its warnings.

    Yeah, the ECMWF shows thundery rain throughout Tuesday night and Wednesday early morning but not any signs of the afternoon thunderstorms that the UKMO are suggesting. Hoping that sufficient daytime surface heating could trigger some thunderstorms by afternoon/evening and if any storms persist they may have a chance of becoming severe as bulk shear looks to increase. Still hoping for a very unlikely scenario of extremely heavy rain due to an MCS Tuesday night with strong winds and then discrete severe thunderstorms later on Wednesday.

    Perhaps, there is a risk we could be too far North though (London could do well). An upgrade to amber would occur if there is more confidence on where the storms will form.

    As far as this evening goes, may be some more decent storm potential as CAPE values are similar to yesterday.

    Yeah true. On Today that storm passing to the south of Hull looks interesting and potentially supercellular, Can you see anything rotationwise or on that front?
