Dear Diary,
There’s no getting away from it that no matter which direction cold air will affect the country, be it from the east, northeast or north in the coming days, it will have to come across seas with temperatures that are several degrees above their LTALTA Long Term Average. This is usually defined as a 30 year period by the WMO. for this time of year. Things are starting to cooling down though and it’s good to see the reappearance of the cold blob in mid-Atlantic (see graph of SSTSST Sea Surface Temperatures below) where SST have been falling since the end of September, and the cooler waters in the Norwegian Sea to the north of the Faroes and Shetlands are also managing to hang in there as well.
