I notice that the forecasts are suggesting that the Thames corridor is
going to be particularly snowy tonight. Is that anything to do with
the fetch of the air through the estuary? Is the air cold enough and
the fetch over the sea and the estuary long enough for lake-effect
snow or is there some sort of funnelling of the airstream going on?

Google for the fabled "Thames Streamer"

"frictionally induced surface convergence downstream of the Thames
Estuary" - to quote one of my esteemed colleagues.

I think February 1991 was one example. I remember wading two miles to
Romford town centre in heavy thigh deep snow!

The difference tonight, however, is that there is a breeze present.
The snow in 1991 fell in relatively calm conditions. Had there been a
breeze the drifts would have been phenomenal...

Thanks for the information, all.

Without putting a fine point on it, it's certainly hammering down at
the moment - around 5cm lying now, most of it falling in the past 20
mins or so.

Can someone explain how the Thames Streamer effect works in simple
terms. I've tried Googling but all I got was that it is similar to
the Chesire Gap effect.

Cheers, Alastair.
