The Week Ahead…

Good afternoon everyone.

After a prolonged period of cold frosty weather, the forthcoming week ahead is set to turn a lot milder for all areas.

In general it isn’t looking too bad with most places not seeing too much in the way of rain but nevertheless, when we see milder and Atlantic influences in our weather, it can only mean there will be rain at some point.

Here is your all-important outlook for the next 7 days.

Monday 25th January
Cornwall & Devon
  • 4 to 13 mph
  • NW becoming W later
Dorset & Hampshire
  • 7 to 11 mph
  • NW becoming W later
Somerset & Wiltshire
  • 7 to 12 mph
  • NW becoming W later

A cold start with the risk of ice patches following all the rain or showers of late and run off onto our road networks and pavements.

Once any mist and fog lifts, we will be left with good sunny spells and variable amounts of cloud and a few isolated showers.

Cloud will tend to build during the afternoon from the west which is ahead of Tuesdays weather system expected.

We could see some spits and spots of light rain or drizzle later in the day for west Cornwall.

Tuesday 26th January
Cornwall & Devon
  • 6 to 13 mph
  • S - SW
Dorset & Hampshire
  • 5 to 12 mph
  • S - SW
Somerset & Wiltshire
  • 4 to 12 mph
  • S - SW

A dull day with outbreaks of light patchy rain on and off throughout the day slowly clearing east during the evening.

A freshening breeze also which will help lift temperatures across the Southwest.

Feeling less cold for all by mid afternoon.

Wednesday 27th January
Cornwall & Devon
  • 10°
  • 8 to 19 mph
  • SW
Dorset & Hampshire
  • 11°
  • 7 to 17 mph
  • SW
Somerset & Wiltshire
  • 6 to 15 mph
  • SW

A dry start to Wednesday during the early hours of the morning however by dawn, rain would of already arrived across Cornwall and Devon, spreading to all areas by mid to late morning.

Once this rain sets in, it looks likely to stay with us all day only slowly easying from the west after dark.

Some of this rain will be heavy and persistent, leading to some localised flooding due to saturated ground so care is needed.

Behind the rain overnight into Thursday, showers will pack in, some heavy potentially thundery.

Thursday 28th January
Cornwall & Devon
  • 12°
  • 11 to 35 mph
  • W - SW
Dorset & Hampshire
  • 12°
  • 10 to 33 mph
  • W - SW
Somerset & Wiltshire
  • 11°
  • 9 to 27 mph
  • W - SW

Showers sums up the day.

Widespread heavy potentially thundery downpours with the added risk of hail.

Some sunny spells in between the showers and feeling a lot milder with temperatures getting up into double figures.

It will also be a windy day with the risk of winds touching gale force on exposed coasts and hills, more so in the heaviest of the showers.

With already saturated ground, localised flooding is an increasing risk across the Southwest, especially after the rain of Wednesday.

Friday 29th January
Cornwall & Devon
  • 10°
  • 11 to 23 mph
  • W - SW becoming W - NW later
Dorset & Hampshire
  • 11°
  • 11 to 23 mph
  • W - SW becoming W-NW later
Somerset & Wiltshire
  • 9 to 19 mph
  • W - SW becoming W - NW later

Unfortunately yet more rain is forecast for Friday.

The rain will generally be light and patchy but with us all day along with gusty winds, strong on exposed coasts and hills.

Temperatures holding up near or into double figures for one more day as colder air arrives yet again as we push into the weekend.

Saturday 30th January
Cornwall & Devon
  • 10°
  • 7 to 18 mph
  • W - SW becoming NW later
Dorset & Hampshire
  • 10°
  • 6 to 18 mph
  • W - SW becoming NW later
Somerset & Wiltshire
  • 4 to 15 mph
  • W - NW

A day of sunny spells and showers.

Some might be heavy locally torrential but others will remain dry.

Staying mild for one last day but temperatures will start to fall as we move into the evening as winds switch direction.

Winds also gusty, especially for exposed coasts and hills and in the heaviest downpours.

Sunday 31st January
Cornwall & Devon
  • 9 to 14 mph
  • NW becoming SW - S later
Dorset & Hampshire
  • 9 to 12 mph
  • NW becoming SW - S later
Somerset & Wiltshire
  • 5 to 11 mph
  • NW becoming W-SW later

We wake to much colder air sitting across us once more.

Temperatures will struggle throughout the day staying in single figures but majority should stay dry until after dark.

There will be a lot of cloud around and most or fog patches first thing but these will lift.

Showery rain will arrive later in the day and spread to all overnight into Monday. Some of the patchy showery rain could turn to sleet and snow for the highest routes of Dartmoor, Exmoor and Bodmin Moor.
