*February*
The first 10 days of the month look as it'll see a mainly westerly orientated flow across all areas of the UK, this be strong at times with gales in exposed western and northwestern areas, low pressure tracking close to the UK at times. Rain will be heavy at times, but carried through quite quickly on a brisk flow, the flow may swing into the southwest occasionally and this will ensure that temperatures will hold up quite nicely for much of the time across all areas of the UK.
There are indications that somewhat colder conditions will establish through the middle of the month, while remaining unsettled with low pressure having the main influence, some wintry precipitation is increasingly likely.
As winds fall lighter for a time, frost and fog will become a problem. Low pressure is anticipated to be the controlling influence, wintry showers may be expected almost anywhere from time to time before dying away as a weak area of high pressure takes centre stage.
Through the third week, low pressure approaches from the west with a strengthening south-easterly flow across all areas, the threat of a wintry mixture of precipitation crossing the UK as a westerly change brings Atlantic air through to showers and brighter conditions.
Pressure rises at the very end of winter, an anticyclone crossing the UK, winds falling light for a time, before a southerly drift establishes over all areas, becoming less cold thereafter.
*March*
The first month of spring begins with high pressure looking likely to be in control and a fine and dry, mild start, a southerly drift covering much of the UK. This scenario is expected to continue although temperatures falling back with overnight frost with some rain affecting western Britain as low pressure approaches from the west.
The Atlantic will be attempting to push into western Britain, with its associated rain, buts this eastward progress may be erratic and undetermined as high pressure to the east may remain as a block?
A southerly flow may be strengthening as this battle takes place, although by mid-March the Atlantic will have taken control, rain pushing through on a westerly with strong winds and rather unsettled conditions for all areas.
The latter stages of March sees, higher pressure to the east or southeast over the near Continent, low pressure mainly affecting the northwest of the UK, where it'll be unsettled, southern and eastern Britain drier at times with any rain patchy and weak, mainly mild everywhere.
As the month draws to a close, high pressure takes control, conditions settle and spring may have arrived with temperatures lifting across the UK.
