This period will be dominated by high pressure to the northwest of the UK and lower pressure to the southeast over the near continent, and the extent to which either of these systems dominates at any particular time. The wind will probably therefore predominantly come from a northerly direction, so temperatures overall are likely to remain around or a little below average, with any warmer conditions will generally be further west - and near some eastern coasts it could feel quite cold at times. There should be a reasonable amount of dry weather around, especially in the north and west, but some rain or showers are likely at times, most-likely in the south and east at first, but with an increasing risk elsewhere towards early May.

In this period, the chances of unsettled weather are slightly less than usual in the north and about the same as usual further south. Therefore, some spells of wetter weather are likely for all, but perhaps especially southern areas at first with the driest conditions probably further north. Temperatures will probably near or a little below average at first, but likely to recover to around or a little above average through early-mid May. Also worth noting that average temperatures themselves rise by around 1C per week at this time of year.
