BBC monthly outlook
Summary
Mainly mild with spells of wet, windy weather
_________________________________
Saturday 1 February – Sunday 9 February
Unsettled and mild, but with a short cold spell
After a cold start to the week when we had snow in some parts of the country, temperatures have been on the up. It has been rather unsettled with showers and rain affecting the country most days of the week. This weekend won't see much change to this pattern. Both Saturday and Sunday will see showers and rain moving across the country. It will be windy in some areas too, so despite the mild air we're currently in it might feel a bit chilly. Monday and Tuesday will see a deep low pressure system moving close to or across the north of the country. This system will bring very strong winds to some areas - gales, severe gales are likely, and it could become stormy over Scotland. There will be showers and rain too.
As the low pressure system shifts eastwards, we will see a spell of northerly or north-westerly winds developing. It will become colder in all areas, and with the strength of the wind on Tuesday it will feel chilly. At the same time as the low shifts eastwards, we'll see high pressure building to the south-west then west of the country. This will drift overhead on Wednesday, which looks dry and calm, especially compared to Tuesday, but still rather cool. Later in the week, the ridge of high pressure will decline, and we'll see a return to westerly winds. Then end of the week looks milder but windier and wetter. There's even a chance of another spell of very windy weather next weekend.
Monday 10 February – Sunday 16 February
Very wet and very windy ... but still mild
The trend towards wetter and windier weather at the end of next week is expected to continue. We expect a powerful jet stream over the North Atlantic Ocean to drive deep low pressure systems into the UK. The upshot of this is that the week looks like a wet and very windy week. There will be the risk of one or more spells of stormy weather, and disruptive winds are perhaps more likely than we've seen so far this winter. Showers and heavy rain are expected too, especially but not exclusively in the west. Given that as the ground has not had a chance to dry out from the very wet autumn and early winter, there is likely to be a threat of flooding.
The other notable feature is that our winds will be coming in from a relatively warm Atlantic Ocean. This means that it will remain milder than normal for the time of year.
We haven't seen a lot of cold weather this winter, and it looks rather unlikely that we'll see anything in this part of the month, except for very brief spells of something cooler between weather systems. Sleet or snow is possible on high ground in the north, but we don't expect any significant snow to lower levels.
Monday 17 February – Sunday 1 March
Unsettled at first but calming down later
At first, there won't be too much change to the weather after mid-month. Atlantic weather systems will continue to move in, bringing more very unsettled, perhaps stormy weather.
With the weather expected to remain wet with only short drier spells for any recovery, there will still be an increased risk of flooding. Strong winds are expected to continue across the country, probably causing some disruption too. It will remain mild. After such an unsettled month, it will be some relief to see that the weather should start to quieten down towards the end of the month. This is likely to be the result of high pressure building from the south as the jet stream drifts northwards.
It does mean that the south of the UK will see an improvement in the weather first, whilst the north remains unsettled for longer. Western parts of Scotland may stay a little wetter than average until quite close to the end of the month. It is too early to say whether we'll see another spell of "anticyclonic gloom", with a lot of cloud, mist and murk but it is a possibility. However, high pressure could also bring settled, clear, crisp conditions which might allow a few cold nights - similar to what we'll get at the start of February. We still don't see any signs of any prolonged cold and widespread snowy weather developing. In fact, one theme that does continue right through until the end of February and start of March is the mildness. Temperatures are most likely to remain above normal for the time of year through the last couple of weeks of the month.
Further ahead
We'll update the details of the stormy weather we expect around the middle of February.
