The worst of the weather on Friday was during the early hours with the strong winds gusting to 33mph and heavy rain. By mid-morning it had brightened up that allowed the thermometer to rise to a maximum of 10.0C at 13.59 being 2.9C above my long-term average. In fact the thermometer was up and down over the past twenty-four hours. At 21.30 the air temperature was 5.5C following that the temperature began to rise slowly reaching 7.5C at 01.30 early Saturday. This was obviously due to cloud cover arriving and backed up with the evidence of rainfall falling in that period, from 00.30 to 01.30, amounting to 1.3mm. From that time cloud obviously began to clear as the temperature began to fall away reaching a low of -0.1C at 08.00 under clear blue skies.

Saturday after dawn revealed clear skies and the evidence of a dry and sunny day as the barometric pressure has been rising due to Storm Éowyn easing away over Scandinavia. The barometric pressure has risen to 1004.5mb at 08.00 after the low of 988.2mb early Friday, a significant rise of 16mb.

The synoptic charts show another depression in mid-Atlantic heading our way with a track that will take it further south, the time over middle England. This depression, like Storm Eowyn, is forecast to deepen rapidly and bring strong winds and heavy rain on Sunday.

The temperature hovered around 4C for many of the daylight hours with a minimum of 4.2C at 19.05. However, with Storm Éowyn approaching the temperature began to slowly rise reaching a maximum 10.6C at 06.49 early Friday. Usually the maximum is during the day and not overnight. This temporary warmer air made it the second warmest twenty-four hour period this month after 12.4C was logged on the 5th. The several hours of rain during the day stopped just after 13.00 with occasional, sharp showers midafternoon. A weather front crossed our area during the night that produced more rain from 01.10 to just before 07.00 early Friday totalling 17.7mm that took the monthly total to 68.2mm when the long-term average is 89.6mm.

Friday after first light revealed the back edge of the weather front easing away eastwards with the sky beginning to clear with the prospect of modest sunshine during Friday. The rain has stopped and the wind abated. The barometric pressure is beginning to rise rapidly as the centre of Storm Éowyn heads towards Scandinavia. By 09.00, under clearing skies, the temperature had dropped over 2C to reach 8.1C with a little wind chill making it feel like 7.8C outside.

Being some fifty miles inland, the strength of the wind is considerably diminished from that logged at the coast, due to it passing over the ground, trees and buildings that produce considerable friction.

The soil temperature at a depth of 5cm read 7.2C at 08.00 due to the warmer air late yesterday and overnight, which was the highest since the 1st (9.4C).

The track of Storm Éowyn was correctly predicted with the centre over Northern Ireland and Scotland. The pressure at 08.00 here was 988.2mb whereas in the north the pressure at the centre of the storm dropped to an exceptional 944mb. This explains why we only had a modest maximum gust of wind of 33mph at 02.27 early Friday.

Wednesday gave us a bright, dry and calm day although once again the maximum of 4.5C, logged at 15.56, was below average at -2.6C. The thermometer hovered around 3.5C for most of the evening but just before midnight the temperature began to drop with a minimum of -0.2C logged at 02.14 early Thursday, which was 1.4C below the long-term average. The barometric pressure, having been dropping steadily for several days, changed little.

Thursday dawned slowly under low, thick cloud as a warm weather front crossed southern England. There was also light rain and drizzle with the wind beginning to pick up after so many calm days. The temperature had recovered to 4.3C by 08.00. The wind has now changed from North to southwest as the storm approaches.

Storm Éowyn has been deepening steadily and forecast to have an exceptionally low centre pressure later today of 938mb as it approaches the UK. The track of this intense depression is now forecast to head towards Scotland over the next twenty-four hours. The forecast gusts over our area on Friday are up to 53mph.

News Flash:

The European Storm Forecast Experiment has just issued a level 2 warning of possible tornados on Friday ahead of Storm Éowyn. They say the chances of parts of the south having the rare rotating weather pattern “cannot be ruled out”. The south of England is said to be of potential risk of tornados, especially between Bristol and London.

Apologies that the 2025 Data sheet could only be accessed previously by opening the 2024 sheet, which I was not aware of until today. My webmaster has now resolved the glitch.

There was minimal brightness on Tuesday morning that resulted in the temperature eventually rising to a maximum of 5.9C at 12.16, which was 1.2C below the average. Cloud built up after midday that limited any further rise in temperature.

Wednesday began with very misty conditions, humidity at 99% and a temperature of 2.6C at 08.00 as a cold weather front crossed our area, that should slowly improve in the late morning. These conditions are the result of the two depressions, to the northwest and southwest of the UK, easing in from the Atlantic. The barometric pressure has fallen to a low of 1005.3mb, down a significant 46mb since the 12th, the lowest since the 6th. As these the depressions move eastwards they have resulted in the wind backing into the north and northwest today.

The recent Arctic air over North America has been merging with tropical air from the Bay of Mexico producing a strong temperature contrast fuelling a very powerful Jet Stream, possibly as strong as 250mph. This will rush across the Atlantic likely bringing with it a very low-pressure system arriving on Friday that has been named Storm Eowyn, the fifth of the season. The forecast centre pressure is thought to be an exceptional 948mb before it reaches the UK. The most recent estimate is that the track of this storm will be to the north of the UK although the forecast is for winds to increase to around 47mph at their peak over southern England.

The brief spells of weak sunshine, after the fog cleared on Monday, raised the thermometer to a peak of 7.2C at 14.10 making it the warmest day since last Thursday and just equal to the 40-year January average. This was an improvement after four days with below average maxima. Overnight the temperature eased downwards to reach a minimum of 1.6C at 07.37 early Tuesday that briefly produced a ground frost away from buildings and the town centre. It was a dry day with the UV peaking at 0.7.

Tuesday after first light revealed broken cloud that was quite high being such an improvement over the last week when each day had began with thick, low cloud. However, the latest radar shows cloud increasing from the west.

There are two depressions in the eastern Atlantic, just north of Scotland and the other west of Iberia, that are nudging our way but still kept at bay by the recent very high pressure system that is continuing to drop away, another 4mb fall over the last twenty-four hours. The bar,tricpressire at 08.00 was 1015.0mb, down a significant 26mb since last Sunday week.

The recent Arctic air over North America has been merging with tropical air from the Bay of Mexico producing a strong temperature contrast fuelling a very powerful Jet Stream, possibly as strong as 250mph. This will rush across the Atlantic likely bringing with it a very low-pressure system arriving on Friday that could be a new named storm.
