Just heard on the radio a widespread fall of ash, accompanied by light
levels low enough to turn street lights on, in the area north of
Portsmouth. No sign of anything in Southampton, just clear and hazy.

Can anyone confirm this? Sounds like the ash was falling from the sky
like snow from the reports, though that could be exaggeration.

Thanks for the report Nick - on the high resolution visible channel from
EUMETSAT there is a very interesting area of indeterminate cloud around
the Southampton area, with patches to the west. I hope to see further
images uses an ASH derivation from the IR channels soon.

Cheers

James

I wonder, James, if you are referring to the area of sea fog that has been
making its way westwards along the Channel throughout the afternoon. That
seems to be in the IOW/Southampton area near 18z. Above that, there are some
patches of upper cloud moving rather quickly east. To the north, inland
there is a line of convection, (just given a shower here in Wokingham),
which is associated with low level wind convergence, and the resulting
concentration of haze and thicker cloud is causing the low light levels.
