In many ways, the prospects of high pressure being in charge for the rest of this month is actually bad news for us in terms of rainfall. We did get some rain at the weekend, but this was still not enough to alleviate the dry start to this month which we have had in these parts. Furthermore, the rain which we did get at the weekend was still not as much as what other parts of the UK got.

Here in the east of Scotland, I am living in what is probably one of the driest parts of the UK just now, and an area which badly needs to start seeing some sustained rainfall if we are to reduce the rainfall deficit which has built up over the summer months. With high pressure now being forecast to be in charge for the foreseeable future, it looks as though not only are there no signs of that deficit being reduced, but that deficit is just going to grow even larger over time as we go into an even drier spell of weather during the foreseeable future.

This means that if we were then to have a dry winter and a dry spring, things could then get extremely serious and critical, especially if we were to then, go into another dry summer next year as well. That is the most worrying aspect of having high pressure in charge during the foreseeable future, but is only one aspect of that because there is also the question of whether this will be a clear high or a cloudy high. If it is a clear high, the outlook could actually be quite interesting because this is around the time of year when we would expect to be seeing our first official air frosts, and the best chance of that happening is going to under high pressure with clear skies at night. Could the fact that we are going to have high pressure around, mean that we now finally get our first official air frosts of the season which has eluded us here in Edinburgh until now?

However, it would just be like the thing if we ended up under a cloudy high. If that happens, then our borefest just goes on because those cloudy nights would mean that the temperatures carried on refusing to drop at nights, and there is also a risk of us going into a real and proper permacast hell during day with each day being yet another boring and overcast grey nothingness, with yet more constant grey skies.

That is an intense high pressure, some local pressure records maybe broken for October.

Will it be a warm high or a cold high? A cloudy high or a clear high?

Probably depends on your location. Looks like being clear to the south and west, but overcast in the far north and down the east coast - judging from its position and orientation.


Where it is clear, the nights of course will be colder, but the days warmer.

Another chart for weekend of 27th-28th looking rather cold

Usual reservations on model accuracy as it is 9 days away, but does seem to suggest a cold incursion from North

Plenty of -AO/NAO and cold anomalies in the latest EC46 update (just out) for most of November.

GFS doing its usual tease and shifting the cold plunge east just enough to miss us; then suggesting it'll all happen again a week later.

That would be cold enough up here for some hill snow to moderately low elevations (maybe 2-300m)

It’s not an Express style snowmageddon but it may give a small number of people the first small brief foretaste of winter.

I think it would give snow to low levels in northern Scotland and potentially a sizeable amount as the lake effect ramps up to 11. It would be one of those situations where an inch or so of snow is lying at 8am in Wick but is all gone by lunchtime as the snow turns sleety or to rain. Away from northern scotland light or moderate rain showers with some wintryness over the hills.

Next weekends cold shot looks like more of an upgrade this morning. The charts in FI appear to show a recurring theme

Surprised this place isn’t more busy. The amount of blocking around and those potential heights over GL are starting to look mouthwatering.

Feels good to see these early in the season rather than looking for scraps.

Next week's cold shot is looking quite potent and possibly comparable to the October 2008 one which brought several cms of snow to the Chilterns and a covering in central London.

It's looking like Northern and Eastern Britian will see something wintery next weekend. However I would expect a few chilly days and maybe the odd frost for us in the Southwest. If any showers do make it down this far Dartmoor and Exmoor could see a dusting.
