Outlook for the UK over the next 6-30 days

UK Outlook for Wednesday 1 Mar 2017 to Friday 10 Mar 2017:

An unsettled picture is likely at the start of March, as further weather systems affect the UK from the Atlantic. Frontal systems will cross the UK, bringing cloudy and wet weather at times, with some snow over northern hills. It will be rather cold at times in the north, with temperatures closer to average in the south. The changeable Atlantic influence is expected to remain in place through early March, with strong winds and rain at times and possibly gales. Temperatures will be around normal, and possibly a little above average in the south. In between frontal systems, there is likely to be some spells of drier and brighter weather with some showers and patchy overnight frosts.

UK Outlook for Saturday 11 Mar 2017 to Saturday 25 Mar 2017:

For the rest of March signals are weak and confidence is low. It will probably be rather unsettled with spells of wet and windy weather at first, interspersed with brighter and showery conditions with some snow possible across the north of the UK. There should, however, also be some drier and brighter spells, where we may see some local frost and fog at times overnight. Temperatures are expected to be slightly above normal for the time of year. However, there remains the possibility of seeing a more prolonged cold spell, with an increased chance of snow in places. This is more likely later in the period.
