High pressure loses its grip, but for how long?

Just a fortnight ago, a series of relatively intense weather systems brought a wintry spell of weather for all parts of the UK, with snow for many areas, accompanied by gales at times. Conditions settled down somewhat into last week though as an anticyclone built over our shores, making for a rather quiet week in general terms. That said, the cold and dry air that filtered across southern and eastern England from the intensely cold continent brought some interesting temperature contrasts across the UK. On Tuesday, the daytime maximum temperature struggled to reach just 2 Celsius at Langdon Bay in Kent, in stark contrast to a very mild 13 Celsius at Aboyne in Aberdeenshire. As the week progressed, the cold, clear, sunny conditions in the south gradually moved north to give all parts a pretty chilly end to the week.

The week ahead will begin with high pressure still firmly in control of the weather across large parts of the country, but as we head towards the coming weekend, weather systems will likely bring the return of a slightly milder feel.

February also looks like starting on a relatively unsettled note, but there are signs that pressure may start to build from the southeast again towards the middle of the month.

Read on to find out the details...

Diluain 23 Am Faoilteach—Didòmhnaich 29 Am Faoilteach
Gradually becoming milder for most, but not all!

After a particularly frosty start on Sunday morning (with patchy snow for mid-Wales, the West Midlands and Scotland), and temperatures of -8 Celsius recorded across southeast England, Monday isn't beginning on quite as cold a note. That said, the cold continental air which is hanging on means some harsh frosts still. The fog that will likely affect many parts of the country, particularly across southern and eastern parts of England, may linger in places, but elsewhere a relatively fine and dry day is expected.

Tuesday will begin with a frost again, with further foggy patches for southern areas, but a mostly fine and dry day is expected again for many although northwestern areas will turn wetter, windier and milder as that dominating high pressure starts to give way to Atlantic weather systems.

By Wednesday, drier air filtering in from the south and southwest will end the risk of early morning fog patches, with another largely fine and dry day expected for most, but again, conditions will be wetter and windier to the northwest. Thursday is expected to be broadly similar to Wednesday,

Through Friday and into the weekend, the high pressure system that has been keeping the Atlantic weather systems and the onset of milder air at bay for so long will finally slide away to the southeast. Consequently, most parts of the country will experience some wet and windy weather at times, with all areas become less cold.

February to start on a wet and windy note.

The final month of winter looks as if it will get off to a breezy and relatively mild start across most parts of the UK. At time of writing, the overwhelming majority of forecast computer models suggest that the jet stream will push a series of Atlantic weather systems from west to east across our shores. The heaviest and most frequent rain and the strongest winds are currently expected to be most prevalent across northwestern parts of the UK, with southeastern areas staying driest for longest. Although winds will likely often be strong, a slight frost is still anticipated for sheltered rural areas in the east at times.

Diluain 6 An Gearran—Didòmhnaich 19 An Gearran
High pressure to return across the southeast?

As is always the case, confidence in details of longer range forecasts tends to tether off significantly as we project further and further into the future. Even taking this factor into account, trends for the weather during the middle of February are proving difficult to determine. At this stage, analysis of the available forecast computer model data suggest that the relatively mild, wet and windy theme from the previous period will continue on into the middle of February. There are however some indications that pressure may start to build again across southeastern areas of the UK, which could mean the return of harsh frosts and cold sunny days for this part of the UK.

An ath sheachdain

After what will most likely be a relatively mild start to February, are there any signs of a return of prolonged cold weather? Find out in next week's issue.
