Daffodils Delight, Spring has Sprung By Matt Hugo - March 20, 2015.

OVERVIEW: Today (Friday) marks the start of spring, officially, with today being the spring solstice in which there is an equal amount of light and darkness and from here onwards through to June the days gradually get longer, in terms of the amount of light. With high pressure dominating the weather this weekend then some areas of the UK will take advantage of the increasingly long days now with plenty of sunshine, but, as with some areas this past week some stubborn cloud is likely at times too.

ANALYSIS:

1) This is a large area of high pressure both at the surface and within the upper atmosphere. It is this feature that will remain situated over and just to the west of the UK throughout the weekend to produce further fine and settled conditions for most areas. The position of the high pressure will be as such that some weather fronts will move over the top of the high pressure to bring cloudier conditions to northern Scotland as the weekend progresses, but this will be the exception to the rule.

SATURDAY and SUNDAY: Both Saturday and Sunday can be grouped together this weekend given that both days will have similar conditions. High pressure will lie across many areas of the UK on both days, but noticeably on Saturday the position of the high pressure will be more to the west of the UK and this will allow for quite a chilly NE’ly wind to develop across E Anglia and SE England through the day. Equally what this will also do is bring a lot of low cloud into eastern and south-eastern areas of England off the North Sea and this, as a result, will lead to quite a grey and chilly day across this part of the UK. Also as Saturday progresses cloud will increase across northern Scotland with some outbreaks of rain and showers developing here. Elsewhere, however, conditions will be markedly drier and brighter with some bright or sunny spells, especially across SW Scotland, Ireland, NW England, Wales, Midlands and SW England and this is represented well in the forecasted temperatures on Saturday afternoon with clearly cooler conditions further east beneath the low cloud in comparison to higher temperatures further west where there is more sunshine through the afternoon.

Overnight on Saturday and into Sunday will be quite chilly nationwide, but as would be expected the lowest temperatures will occur where there are most cloud breaks and, at the moment, that is most likely to be across parts of N England, Wales, Midlands, SW England and Ireland, whilst in contrast more northern and eastern areas of the UK are milder given more cloud and this is represented well by the temperature chart below for Sunday morning at 0600z. Equally, note the precipitation across N Scotland by Sunday morning too, so Sunday starts cold and frosty in some places but equally milder and cloudier in others.

As the rest of Sunday progresses northern areas of Scotland will remain cloudy, breezy and with an on-going risk of some rain and showers, but this will be the exception to the rule. After the chilly start many areas of England, Wales and Ireland will then be dry with bright or sunny spells developing. Further areas of low cloud are possible in places, but generally Sunday should provide a more widespread risk of cloud breaks into the afternoon with bright or sunny spells developing more widely. Given light winds through Sunday afternoon then it will feel pleasant in the sunshine after the chilly start. The 10KM model highlights the wet weather in the far north, but clearly many areas are dominated by high pressure and fine and settled conditions. Note as well by the middle of Sunday afternoon temperatures have recovered quite nicely with a large portion of the UK seeing maximum temperatures near 9C to 13C and again when this is coupled with some sunshine and light winds then it will feel rather pleasant.

As Sunday evening progresses then it will turn chilly once again across England and Wales beneath clear skies, but the trend for the end of Sunday and into early next week is for the wet and rather breezy weather across Scotland to move south-eastwards into late Sunday and early Monday bringing some wet weather with it. Also of importance is that a drop in temperature is expected into early next week too and, as a result, after the pleasant conditions this weekend temperatures early next week are set to become below average with it feeling quite cold and with some wintry precipitation possible too. So, the changeable weather that March can often produce will continue in the coming days. I’ll have full details on next week’s weather on Sunday as usual.
