I feel like a traitor now! (and also worried that I'm coming across as a flouncy drama queen) What I don't want to do is just to leave without anything that I can jump to. I love posting here, it feels like a privilege to share weather info with people.
Biggerboy I don't want to rehash my reasons here, this is our weather space. I've detailed my concerns in site stuff.
GFS does not want to let go of the idea of bringing in cold weather from around 6th March. The latest run doubles down on the idea of bringing in some pretty cold upper air temperatures. Remember, these aren't temperatures that we would feel, but tell us how cold the air mass is and hence what precipitation might come in the form of.
For example the chart below. Once we get to around -10c ish on an 850hPa chart in March, then snow is quite possible where precipitation happens. Daytime temperatures look around to about 5c max, which would allow snow to reach ground level if it is intense enough. However, the chart also looks very dry, with precipitation only in the east.
Remember this is just one model run, some way in advance. I'll try and look at the ensembles later.
