Fri 12 Dec Northern Ireland

A continuation of a similar pattern to that seen through early December is anticipated, especially at first, as frontal systems from the Atlantic spread into and across the UK, interspersed with some temporary drier interludes. These will bring occasional spells of rain, which may be heavy at times leading to the risk of some impacts given how wet it has been lately. In addition, there may also be potential for some periods of strong winds at times too. Whilst it will often be mild, later in the period there may be a slight downward trend in temperature, especially across northern parts of the UK where there may also be a slightly higher chance of some wintry hazards at times.
