Looks like the Met Office may have flagged the 1500 and 1600 readings
as suspect - the usual red bars athttp://www.metoffice.gov.uk/weather/uk/se/solent_latest_weather_graph...
are "whitened" out but the reported temperatures are visible.

I think that's just sloppy coding on the website. Those bars are
supposed to be 14 units high - see image filename
http://www.metoffice.gov.uk/lib/imag...ph/grid14r.gif - but the
site only has graphics up to 13 units high:

chosen the wrong scale for the graph, in other words, and those two
hourly readings have gone off the scale.
