He went on to say the UKV should peform better.

I suspect the model is overdoing the extent of the minima but I have seen a good number of models showing minima approaching -20°C in parts of Scotland over the past few days. As you say though it is certainly dependent on snow cover being in place.

A stunning t+48 chart from the 12z ECM 🤣.

Let’s see what this run does. I’m a bit gutted that the heights to our NW are due to relax so quickly in most of the output - often when it comes to snow, it takes a day or so for the convection to properly kick in.

Yes, that is the great fear. I think White Meadows outlined this risk earlier this week. Let us hope it doesn't transpire.

Whether it’s someone’s cup of tea or not and if (or more bizarrely why) it rubs certain elitists up the wrong way by merely pointing it out is a different matter entirely. 
Let’s see if ECM joins the potential rainfest for the end of next week. Hopefully not but we can’t put the blinkers on to possible threats of further flooding.

Well the ECM certainly looks snowy. Completes a good set of 12s.

ECM bringing in the Atlantic. In southern and central regions it all seems to depend on the mid-week event.

Possible snow event from north west on latest meto at t114+?

The weekend northerly looks like more intense cold and a more southerly reach on this run too

Taking the GFS and ECM op runs at face value, and the GEFS - it looks like milder air will take over UK-wide next weekend.

We’re looking at a week-long cold spell.

I hope many get something out of it.

I have had a trawl back through all the charts I have saved in the last week or so and the period around the 21st has signalled a general end of the cold spell. That of course could change.
