May not be particularly on-topic but the MetOffice 16-30 day forecast has been updated:
"The forecast for the first half of February is very uncertain. As with the day 6 to 15 forecast, there appear to be two main scenarios, each equally probable, but which are very different. It is also fairly likely that the prevailing weather type at the end of January will continue into February. The first scenario consists of a changeable westerly or southwesterly type, with rain at times (amounts greatest in the west), and with temperatures noticeably above average for early February, with only occasional frosts. The alternative scenario is that very much colder weather, with winds from an easterly or northeasterly quarter, will prevail well into February, bringing widespread frosts, and snow to some areas. In this scenario it would be the east that was most vulnerable to snowfall"
Seems like there is a slightly less than 50% chance of cold weather in early February - ties in with some of the ensemble model output I guess....
