A turbulent weekend

The effects of Storm Atiyah were felt again on Sunday giving us another stormy day with winds frequently gusting over 20mph and a peak gust of 37mph at 04.43 Monday morning. The worst of the storm was to the west and south of us with the Meteorological Office changing there warning on Saturday, removing our area, as the depression moved across the north of Ireland. The Needles recorded winds in excess of 80mph.

Temperatures by day and night were mild, both maximum 9.3C (+2.0C)and minimum 5.0C (+2.8C) were above average.

Several rain storms produced a total of 5.1mm bringing the monthly total to 17.3mm.

Monday brought a bright start to the day with broken cloud and the wind moderating.

A turbulent 24 hours

Saturday brought us a mild day with the thermometer hovering around 9C for much of the day but just after 18.00 a warm front passed over the area that raised the temperature to 11.3C at 03.39 Sunday morning. This high was 3.3C above the 35-year average.

The significant feature of the past twenty-four hours was the wind speed, which rose steadily after 20.00 with a squall at 22.27 when a gust of 34mph was recorded. There were other strong gusts after midnight peaking at 26mph and then dying down a little.

A rain band associated with the warm front lasted for a couple of hours just after midnight producing 5.8mm of rainfall.

Sunday saw broken cloud after dawn and the temperature dropped back to 8.8C

Mild by day and night

Friday was the first sunless day this month although it was mild by day and night. The warm air meant the thermometer steadily climbed to a maximum of 11.6C at 12.41 before slowly dropping back to around 7C late afternoon as the wind veered from the southwest into the west.

The peak of 11.6C was 3.6C above the 35-year average and the minimum overnight, due to heavy cloud cover, meant the low of 7.3C was 5.1C above average.

A modest rainfall of 2.0mm was recorded.

Saturday saw total cloud cover after dawn but with the wind having abated.

Warmer by night than day!

Thursday started with a temperature of -1.2C and fog at 08.00 but by late morning the fog began to lift and the thermometer to slowly rise so that by late afternoon it was reading 7C. As the warm front travelled across the country the temperature continued to rise so that by 08.00 on Friday the thermometer was reading 10.8C, which was almost 3C above the average December maximum.

There was a light shower mid-evening but more continuous rain in the early hours that amounted to 4.4mm. Not since mid-September have we enjoyed four continuously dry days.

Friday dawned with thick cloud and a brisk wind from the south west after the strong gust of 27mph at 17.40 on Thursday evening.

High pressure lingers

The high pressure was still in control during the past twenty-fours resulting in a very calm day with the fog slowly clearing by mid-morning. The maximum movement of air, cannot be called a gust, was just 4mph, with calm conditions for many hours.

Temperatures were depressed by day and night with a maximum of only 5.7C being 2.3C below average and a minimum of -2.4C (4.6C below average) just before midnight.

Thursday saw thin cloud after dawn providing bright conditions with no movement of air.

The colder days and nights have meant the soil temperature at a depth of 5cm has fallen significantly with a reading of 0.7C at 08.00 on Thursday.
