A very mild weekend but colder by Monday

A very mild southerly flow will lift UK temperatures into double figures this weekend. It won't last into next week but any passing rain shouldn't be heavy or persistent. Good news for flood-hit regions.


Issued: 29th November 2024 12:17

Mild air will take over for the weekend. Quite a change after the frosty mornings. Braemar fell down to -11.1C and some parts of northern England only reached a few degrees above zero by day. At the weekend temperatures will widely be up into double figures, 12 to 15C. 

The jetstream has been away to the north and will weaken this weekend. Frontal bands will move across the UK, one later on Friday and another on Saturday night. Although issues remain from the heavy rain and flooding during Storm Bert, this frontal rain will be showery and moving through at a fair pace. Although the weekend rain doesn’t give cause for concern, there are numerous flood warnings still in place. Ongoing local river flooding in Northamptonshire, Worcestershire and Gloucestershire into the weekend with travel disruption. 

Flood warnings

The cool surface air over eastern England will fade as a milder flow takes hold over Ireland and western Britain by Friday evening. Gatwick up to York could feel more like 3 or 4C on Friday evening with a southerly breeze. Coastal Scotland, western Wales, SW England and Northern Ireland will all be up into double figures with a fresh, sometimes gusty southerly wind. There will be outbreaks of showery rain moving eastwards but fading over England.

Saturday will feel very mild with light southerly winds and areas of stubborn cloud or brighter skies. There will be a few showers over Northern Ireland and Wales in the middle of the day and clusters of showers reaching Scotland from the west. Western coasts of Britain could stick with low cloud and damp conditions during Saturday but to the lee of high ground and for inland Britain temperatures will rise. Potentially into the mid-teens Celsius, not bad for the last day of November. Northern Ireland will be mild but more breezy. By Saturday evening the next cold front, with its showery rain, will be approaching from the Atlantic.

Again this will be a narrow band that continues to move eastwards but it will be slower with heavier pulses. It will be very mild but increasingly windy through the Irish Sea and for Scotland. The Western Isles could see southerly gales overnight as the low centre sweeps past, heading for western Norway. Disruption to ferry services to the Scottish Islands may occur early on Sunday.

So no frost or ice to worry about during the weekend. Sunday will be another mild but mixed day. The cold front will work its way across Britain with some heavier showers. There will be uncertainty about where will see the heaviest pulses and the timing of its passing. So have in mind cloudy skies, then a spell of wet weather which passes allowing brighter skies. The rain is forecast to reach London late afternoon or evening with clusters of showers feeding in from the far northwest of the UK. 

Sunday night will see another change, to a northerly flow and the start of colder Arctic air arriving. 

For the start of Monday, it will feel bitterly cold in the far north of Scotland with wintry showers and raw wind. The trailing occlusion from the low will be draped somewhere over Britain bringing cloud and rain with the mild air to the south. To the north of this, there will be a chill in the air and a noticeable breeze. All but southern England will be back to a sharp frost by Monday night in the clear, cold conditions from the Arctic. Inverness could see 13C on Saturday but will be down to 3C by Monday and feel like -1C. London could see 14 or 15C on Saturday but be around 7C by Tuesday and feel more like 4C. We will be juggling with our wardrobe choices to keep up with these fluctuating temperatures.

al78 Just using that to identify the storm, where some roadside records got up that high. Agree that he wouldn’t be doing anything in 150mph winds.

swfc probably not but it's likely to keep us drier for longer.

GFS is horrific.

northwestsnow can see the big difference on the ukmo but can the ridge build given the tpv exiting the esb
