UK long range weather forecast

Next week begins with some uncertainty, but it looks likely that we will see a return towards more widely unsettled conditions as another area of low pressure pushes across the UK with changeable weather likely largely dominating throughout this period. Most areas look likely to see further showers and some longer spells of rain at times, although interspersed with some drier spells in between. It looks likely that a north - south split will be set up across the UK. The wettest weather will tend to favour the south whilst northern parts remain a bit drier on average. In association with this split in general temperatures will be close to average, but it will be occasionally cooler in the north, and milder in south.

Updated:

Through mid to late April, pressure is likely to be higher than average to the north of the UK, with low pressure more likely to the west or southwest. This pattern tends to push the focus of unsettled weather further south than usual, with largest rainfall totals more likely to be in the south of the UK. Conversely northern, especially northwestern, areas will tend to be drier compared to normal. A trend towards more settled conditions in the latter part of this period is growing more likely, of course this not a guarantee at this range. Temperatures will probably be near average or slightly above overall, with any cooler interludes most likely in the north early in the period.
