After Will's mention of the low deepening and my temperature rising, now
1.0°C with a dewpoint of -1.0°C, my last post was a reading of 1005.5,
quarter of an hour ago, it is now 1005.2mb and falling fast.

Now *that* is interesting. Thanks Keith.
Your wet-bulb is now zero I note!

Not sure where you're getting that from Will:
Temp 1.1°C
Dew Point -1.0°C
Barometer 1005.1mb Falling (21:20)
Wind NW now 16 gusting to 30mph
What's going on?

You've lost the cold advection near the low centre and the sea is keeping
the air temp up. But it is the wet-bulb you need to worry about, i.e. if the
dewpoint goes up. Once it starts precipitating heavily your temperature
should fall down to 0C. Lighter precip, may start as rain though.
