Summary
Wet and windy at times - wettest in the north

Saturday 15 February – Sunday 23 February
Another wet and very windy weekend to come
The weekend weather will be dominated by Storm Dennis, which will bring severe gales and heavy rain to the UK. Saturday will be a windy day countrywide and there will be widespread showers and rain. Storm Dennis will remain nearby for the rest of the weekend. There will be little respite overnight or on Sunday, with gales and severe gales expected to continue, and with further heavy showers and rain expected. Given recent heavy rain, the ground is still very wet, so there is a risk of flooding this weekend.
It took a couple of days for winds to die down after Storm Ciara moved through last weekend. We'll see a similar pattern with Storm Dennis. By this, we mean that whilst Monday is not expected to be as windy as this weekend, it will still be a very windy day. Gale force winds are possible, and there will be frequent blustery showers. There will be the risk of snow on high ground in the north of the UK, especially later on Monday and overnight as cold air moves in.
Tuesday will be another showery day with the chance of some snow in the north. It will be windy but not as windy as Monday. Wednesday should be less cold, less windy and less showery. However, Thursday should bring a return to wetter and windier weather as the next Atlantic weather system moves through. The rest of next week looks changeable. Atlantic weather systems are likely to affect the country, but there are some indications that the south of the UK might be a little drier and calmer than it has been.
Monday 24 February – Sunday 1 March
Less windy with rain mainly in the north
The final week of February should see a subtle change in the weather. We still expect Atlantic weather systems to affect the UK, but less frequently than we have been seeing. This will be because a ridge of high pressure centred over Europe is expected to expand northwards, this in turn deflecting the track of the Atlantic lows northwards. There is a little uncertainty over exactly how far north the ridge of high pressure will extend, and this has a knock-on effect on winds and rain across the country. However, it should be less wet and less windy for the UK as a whole.
There will still be some rain, this mainly over the north of the country where it may become windy at times. The south of the country should become drier and calmer, although don't be surprised if there is still a spell or two of wet weather. As we've seen for much of the winter, temperatures will be near or a little above normal for the time of year. However, with winds likely to be coming in from the north-west at times there will be some spells of cooler weather.
Monday 2 March – Sunday 15 March
Briefly drier, then wet and windy again
The first working week of March will bring little change to the overall pattern seen at the end of February. High pressure should limit the impact of Atlantic weather systems, so it looks drier and calmer than normal in most areas. Just the north of the UK, mainly Scotland but perhaps Northern Ireland, are likely to see rainfall near normal, perhaps a little above normal locally
As we move towards the middle of the month it looks as though high pressure will either decline southwards or start to drift eastwards. The upshot of this is that we would see rainfall nearer normal across the UK, although still with wettest areas of the country being in the north and west. A similar pattern is expected with winds - northern and west parts look most likely to see windy weather whilst the south and east remain relatively calm.
One thing that doesn't seem to change much in March is that it still looks warmer than normal. We do think there could be the occasional cooler spell but at the moment there are no indications of any prolonged cold weather before the end of winter.
Further ahead
Will there be another spell of very windy weather before we get to the end of February?
