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.

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.
Will
Ok, snowing heavily now, temp 1.1°C, that band on the top LH edge has
moved in from the NE. 1.0°C as I type Dew point -1.1°C
