UK forecast for the next 5 days

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 29 May 2015 to Sunday 7 Jun 2015:

May is expected to end unsettled, with spells of rain interspersed by drier, brighter and more showery interludes. It may be rather windy, particularly in the northwest, with a risk of gales, and the bulk of the rainfall. Southern and eastern areas look best placed for the driest, brightest weather. Temperatures are likely to be below average in the northwest, but near average further south and east. Into June the signal for prevailing weather becomes fairly weak, but, on balance, unsettled conditions are considered more likely in the northwest at first, with slightly below average temperatures, and settled, warmer, conditions in the southeast. Towards the weekend these warmer more settled conditions are likely to spread to most of the country with a risk of showers in the south.

UK Outlook for Monday 8 Jun 2015 to Monday 22 Jun 2015:

There still remains considerable uncertainty in the likely weather type through this period. There is, however, a signal for higher pressure to become established to the north of the UK. This would lead to drier, warmer conditions for many, these perhaps most prolonged in the north, but it may also allow some more unsettled, perhaps thundery, weather to move up from continental Europe and affect the south of the country.
