That said, the temperature at Edinburgh Gogarbank did drop to 0.6°C in the early part of last night with a ground frost (it just didn't quite get cold enough for an air frost here) before the rain eventually set in.

Currently around 4°C here in Edinburgh

The 18z raw BUFR/SYNOP data shows a maximum temperature of 5.0°C at Edinburgh Gogarbank but that covers a 12 hour period which started at 6am GMT (06:00 UTC) this morning which is before the start of the actual official observation day at 09:00 UTC and that is then that maximum temperature was actually recorded.

The actual maximum temperature so far is the highest temperature since 09:00 UTC, and that will only be no lower than 3.4°C and we will have to wait until the 21z raw BUFR/SYNOP data comes in before will know that actual maximum temperature.

I can say that this maximum temperature will probably be less than 5°C as the temperature here in Edinburgh is currently around 3°C.

EDIT:

Today's maximum temperature at Edinburgh Gogarbank so far is confirmed as 4.0°, but the temperature here in Edinburgh is still stuck at around 3°C with the rain having now become heavier once again. 

Cold rain here +2c 

Expecting it to turn to snow tomorrow. 

An inversion of diesel fumes from poorly maintained machinery from the building site. I could complain but the answer will be 'a cold start'.

Think that's our coldest of the season 

A mild-feeling 12.7 C & low 90% H under mod SW breeze. Typical maritime-type fare.

Winter is over!!🥵
