UK long range weather forecast
An unsettled period, with plenty of showers and some occasional longer spells of rain across much of the country, the heaviest and most widespread areas likely in the west or northwest, and only limited drier interludes. Often windy, with a risk of gales at times (potentially severe), particularly around coastal regions and within areas of more significant rainfall. With time, northern parts of the UK may tend to become drier and more settled overall, with low pressure systems tending to track further south. Feeling cold, especially so where there is persistent rain and strong winds. Frost is possible at night in any calmer period, becoming increasingly likely for the northern half of the UK later in this period.
Updated:
A potential change in the weather is signalled around the middle of October. Whilst further rain and strong winds are likely at times, spells of fine and dry weather could become more widespread and long-lived. At night, these calmer conditions would allow frost and fog to form more readily. At this time of year, there is potential for fog to linger well into the daytime. Overall, temperatures probably recovering close to the seasonal average for mid-October.
