Planning Outlook

All mountain areas of Britain from Wednesday 21st February 2018

High pressure which briefly resides across Britain will become centred strongly over Scandinavia later this week, paving the way for very cold easterly winds to develop toward the end of February. Substantially dry conditions for the rest of this week, and most likely through the weekend. A risk of snow developing on eastern hills as the easterly winds arrive. After a brief lift above freezing at the start of this week, temperatures will be below freezing on the mountains for the foreseeable future, so the current snow-pack will substantially remain in place; probably well into March.
