On the 0030 Radio 4 forecast Tomasz Shafernacker said tomorrow morning would be warm and humid in the SE and said there could be thunderstorms, implying a connection between these two phenomena. Rubbish, Tom. There is no really humid surface air on the continent and the surface wind is ESE, at right angles to the movement of the storms which will zip by rather quickly. It could be classified as a brief Spanish Plume.

It really annoys me how careless most weather presenters are with associations.

It's the direct association of wind strength and swell size at the same spot that really irritates me (though I suspect I'm in a minority!)

This week's been a great example. On Monday we were warned that because of the strong winds there were be very large waves along the Atlantic coast for Monday/Tuesday. Really?

Take a look http://www.easterling.freeserve.co.uk/WindSea.html The top photo is from Sennen Harbour early Tuesday afternoon. Out to sea it was still a good F6 & it was rough, but big waves?

Then Wednesday, a calm still, sunny evening. All love and peace on the forecasting front but look at the sea - at that's in the harbour! 12' swell on the beach - that is big for June. That's what I call iffy. I went in at Perranuthnoe & it was fairly exciting. (No lifeguards but I wasn't alone)

Thursday F3-4 SE and much calmer.

A big swell is dependent on fetch, wind strength & duration, and then travels far beyond the area of generation.
