RIP winter 2018/19
BBC monthly outlook
Summary
Often unsettled, but rather mild
_________________________________________
Wednesday 6 February—Sunday 10 February
Remaining mild but unsettled
The remainder of this week will continue the mild and unsettled theme which ended last week's cold weather. Most areas will see temperatures near or slightly above average on Wednesday, with the driest, brightest weather across central and eastern portions of the country. An active front is likely to bring more widespread and perhaps heavy rain into southeastern Britain later in the day and overnight. Heavy showers in the north-west will give way to more general rain across western Britain and Northern Ireland later in the night. Thursday will be rather breezy and a little chillier, with bright or sunny spells and occasional showers moving across western and central Britain. Some of these will be heavy and thundery in north-west Scotland, perhaps bringing small hail.
Overnight, it will become mild and increasingly windy, as a warm front brings outbreaks of rain across much of the country from the south-west. Friday will continue to be mild but windy with rather persistent rain in the west, as a deep area of low pressure moves close to Ireland. There is a risk of gales or severe gales developing in southern and western Britain during the evening and overnight. By Saturday, it will remain very blustery with broken cloud for most areas, and a few showers moving into the west, but winds will tend to ease through the day. Scotland could see more general rain, however. Sunday will become a little cooler for all, with wintry showers edging into Scotland from the north, and a risk of some heavy and persistent rain perhaps affecting southern Britain.
Monday 11 February—Sunday 17 February
Wet and windy in the north.Calmer in the south
Next week will start off with a ridge of high pressure located across the UK, meaning there should be a lot of dry, fine and settled weather around. Winds will be generally light, although there is a risk of some wintry showers edging into eastern Britain from the North Sea. There is a risk of a frost for most as skies clear on Monday night, although this looks like being the last widespread frost for a while, as there will be a quick return to mild but often wet and windy conditions from the Atlantic through the rest of the week. Despite this transition to more unsettled conditions, high pressure is expected to build across France and the near Continent through the week, and will occasionally ridge north towards the UK.
Therefore, much of England and Wales can expect to see drier, calmer days interspersed with occasional patchy rain and breezier weather edging in from the west. Northern Britain is more likely to see some windy and perhaps very wet days, with persistent rain moving in from the west at times, although the wettest weather will always be more likely across Scotland. It will be rather mild for all areas, with temperatures remaining a couple of degrees above average thanks to winds predominantly from the west or south-west.
Monday 18 February—Sunday 3 March
Remaining mild, with an unsettled end to the month
As we look beyond mid-month, we can expect to see some major pattern changes; high pressure is likely to remain quite extensive across the UK to start with, allowing mild south or south-westerly airflows to move across the country, and keeping temperatures well above average. There will be a lot of dry and calm weather, however, as weather fronts are kept at bay in the Atlantic. There are then indications that the high-pressure area will begin to move to the north of the UK, opening the door to more frequent rain-bearing Atlantic fronts advancing towards western Britain. Scotland could end up becoming rather wet and windy for a few days, while a few weakening bands of rain could edge across the rest of the country. There is no risk of significant snow.
The outlook for the end of February and into the start of Meteorological Spring has changed, with a mild end to the month now anticipated. Computer models have trended towards a much less cold and 'blocked' weather pattern by this stage, with a reduced probability of widespread high pressure, and a significantly lower risk of snow. However, it is looking to be rather unsettled, with low pressure areas from the Atlantic often moving across the UK from the west. Although these will bring rather mild westerly or south-westerly airflows, they may affect southern and western Britain than northern areas more often. Therefore, some very wet and rather windy weather is expected across most of England and Wales, while temperatures will be nearer to normal in the north, with a small risk of snow at times.
Next Update
We will see if March has any colder weather to offer, or whether we could see an early start to spring.
