Planning Outlook

North or northwesterly winds will dominate through the rest of the week - most mountains frequently sub-zero onward into the weekend, at times to lower slopes. Some variation of freezing level, mainly toward western coasts and brief tongues of less cold air may move across Wales, perhaps the south Pennines. Frequent precipitation, mostly snow on the mountains, sometimes heavy showers with hail. Winds varied, but often strong, gales or severe upland gales at times.
