The forecast for this weekend is high pressure pushing in from the southwest today. This will slowly be pushed back by the low pressure to the north of Scotland, which will drop temperatures, raise the winds to around 30mph on the tops and drag in a couple of weak cold fronts in the middle of Saturday, bringing a chance of drizzly showers. Sunday looks to be getting better, and Monday looks gorgeous!
This is my amateur interpretation of these sources:
- The met office surface pressure charts;
- Mountain Weather Information Service's Snowdonia forecast;
- Netweather.tv's ensemble view
As for me? I'm going climbing in the Ogwen Valley on some classic and airy VDiffs.
