  1. The more technical will give you a better answer. Basically when winds become ENE in the Thames Estuary allied to very cold air moving over this area, of the sort we've had overnight, deep convection occurs. I also think the local topography of the Essex and Kent coastline gives additional lift to the air. If you look at a map of this area you'll note that the Essex coastline alligns NE to SW and the Kent coastline, more or less east/west. The coastlines narrow to about Southend over to Sheerness and this helps to funnel the snow showers WSW towards London, at the same time keeping the bitter air in contact with a source of moisture, i.e The Thames. This is why areas along the Thames corridor right into the heart of London have received such heavy snowfall and on over the West Kent and Surrey Downs. If the wind stays in this direction for any length of time the showers keep on coming and snow totals increase. The convection can become so deep that reports of thunder start coming in from those areas, as happened overnight.

    I have received some of my best snowfall from these set-ups, as I have lived on the SE.London/NW.Kent borders all my life.

    This certainly ranks up there as one of the best examples of a Thames Streamer that I've seen.

    Still cant quite explain why Paul S. and others in the Southend/Leigh area have done so badly overnight. :D
