January 2017 Weather

January 2017 was dominated by high pressure with plenty of dry and settled weather, indeed had it not been for a particularly wet night on the last day of the month it would have concluded as the driest ever January on my records. However in the end the monthly rainfall total still came to a very modest 36.6 mm (1.44 inches), just 68% of what would usually be expected in a typical January here in central East Yorkshire, whilst rainfall in excess of 1 mm (0.04 inches) was recorded on just nine days.

The anticyclonic nature of the month was also reflected in the frequency of frost during the duration of the month, 13 air frosts, including a low of -4.7 C on the 27th, contributing to the sub-par mean temperature, the average for the month eventually coming to 3.9 C, 0.3 C below the 1981-2010 average. Conversely the dominance of high pressure also meant that the month was often plagued by so called ‘anti-cyclonic gloom’, this helping to depress daytime temperatures by 0.6 C, and in the end the month concluded with a deficit of sunshine, barely 50 hours being recorded throughout the month (about 88% of the long term average).

However whilst the month was largely dominated by high pressure, this didn’t mean that January passed without any notable weather, some strong gale force winds between the 10th and 13th bringing a few reports of minor damage here and there. Indeed the peak gust of 46 knots (53 mph) on the morning of the 11th was the strongest gust recorded at our otherwise sheltered weather station since November 2015 ! Snow also made an appearance this month, albeit rather fleetingly, with a short-lived 2-3 cm falling on the morning of the 13th, this completely thawing within a few hours of falling. Still at least we have yet again avoided the possible threat of a snowless winter, something, which even down here on the East Yorkshire lowlands, I have never experienced in my life.

1st January 2017, Sunday
4.5 C to 5.7 C / 1.6 mm / 0.0 hours / N 4
A dull and wet start to the New Year with outbreaks of rain throughout the morning, though by early afternoon the rain would clear away to the south to leave a grey and blustery afternoon, the northerly breeze making it feel quite chilly. However around dusk skies would begin to clear with some good clear spells developing during the evening and overnight, though a few showers would also sweep down from the north, some of which were a little icy and wintry at times. These would clear by the end of the night though with a light frost and icy patches by dawn.

2nd January 2017, Monday
0.7 C to 4.7 C / 0.0 mm / 6.5 hours / W 4
A clear and cold start with widespread ice, and it would remain sunny and crisp throughout the day, a moderate WNW breeze making it feel particularly chilly, especially in any exposed locations. Clear spells in the evening and for much of the night, this allowing another ground frost, but cloud would increase later.

3rd January 2017, Tuesday
0.3 C to 7.5 C / 0.0 mm / 0.2 hours / W 4-5
A mostly cloudy, cool and blustery day, the fresh WNW breeze again making it feel particularly cold in exposed locations. Clearer for a time in early evening but cloud would increase again later with mostly cloudy skies for the rest of the night. Becoming slightly milder during the evening as well.

4th January 2017, Wednesday
4.5 C to 6.2 C / 0.6 mm / 1.3 hours / NW 4
A dull morning with a chilly northerly breeze, though by midday some brighter periods would develop with some sunny spells for a time in the afternoon. However blustery showers would also drift down from the north during the course of the afternoon, though most of these would be largely brief and light affairs. Variable amounts of cloud in the evening and overnight with a few further showers during the middle of the night, though latterly skies would become clearer with temperatures dropping below freezing by dawn.

5th January 2017, Thursday
-0.3 C to 4.5 C / 0.0 mm / 1.6 hours / S 2
A bright and chilly start to the day with a light frost and patches of ice, though it would become cloudier by mid-morning and would remain so until midday. However thereafter things would once more brighten up with some nice spells of crisp winter sunshine during the afternoon. Clear at first in the evening with temperatures quickly dipping below freezing, but cloud would increase as the evening wore on with mostly cloudy skies for much of the night.

6th January 2017, Friday
-1.1 C to 8.2 C / 2.1 mm / 0.0 hours / S 3-4
A dull and overcast day with periods of rain and drizzle from late morning and throughout the afternoon, the top of the Yorkshire Wolds becoming shrouded in low cloud. However despite the grey skies and inclement weather it was fairly mild. The outbreaks of rain would die out by mid-evening to leave a mostly cloudy night, though latterly some breaks would begin to develop.

7th January 2017, Saturday
2.0 C to 9.5 C / 0.0 mm / 0.6 hours / W 1-2
A bright start to the day but this wouldn’t last long with cloud and grey skies soon arriving from the west. Remaining dull, overcast and mild for the remainder of the day with little change through the evening and for much of the night.

8th January 2017, Sunday
4.0 C to 9.2 C / trace / 1.7 hours / S 3
A dull, overcast and mild start to the day, though by late morning things would begin to quickly brighten up with some spells of early January sunshine developing by midday. Remaining sunny and mild during the afternoon, though by the evening cloud would again increase, skies remaining overcast throughout the night. The breeze would also freshen from the south as the night wore on. Very mild.

9th January 2017, Monday
5.8 C to 9.2 C / 2.1 mm / 0.3 hours / W 4
An overcast and exceptionally mild start to the day, the moderate to fresh southerly breeze feeling quite warm, whilst after 10 am a period of rain would also arrive from the SW, this rain continuing on and off until mid-to-late afternoon. Becoming drier in the evening with clear spells developing overnight.

10th January 2017, Tuesday
2.7 C to 11.8 C / 0.0 mm / 3.5 hours / W 4
A largely sunny and pleasant mid-January day, feeling quite warm in the sunshine with temperatures climbing to just shy of 12 C. However a freshening breeze would make feel it somewhat cooler, this wind continuing to strengthen overnight with frequent gusts in excess of gale force by the end of the night.

11th January 2017, Wednesday
5.7 C to 8.2 C / 0.0 mm / 4.8 hours / W 6-7
A bright day for the most part, though the main feature of the day was the strong to near gale force winds which swept through the East Riding, the wind peaking at 46 knots (53 mph) in mid-morning. Becoming somewhat calmer by the evening with the winds continuing to ease overnight. Clear spells overnight with variable amounts of cloud.

12th January 2017, Thursday
2.3 C to 4.5 C / 2.1 mm / 0.5 hours / W 4
A mostly cloudy and cold day, a keen westerly breeze making it feel particularly cold out in the open, though around dusk the cloud would begin to thin and clear, this also accompanied by a drop in the wind. As a result temperatures would begin to fall, eventually reaching -0.5 C overnight, though increasing cloud and a period of snow towards the end of the night would see temperatures begin to rise again.

13th January 2017, Friday
-0.5 C to 4.7 C / 0.0 mm / 0.4 hours / W 5-6
A snowy start to the day with a period of moderate snowfall at dawn, but this would soon clear leaving a wet covering of about 2 to 3 cm of the white stuff. However temperatures started to rise after the snow cleared, and as a result the lying snow would quickly thaw with most of it completely gone by mid-afternoon. Remaining cloudy and windy for most of the day, conditions feeling very raw out in the open, though by the end of the afternoon skies would begin to clear, this allowing temperatures to dip below freezing overnight. However it would remain breezy during the night, and by dawn the ground was very hard with a ‘wind frost’ penetrating deep into the ground.

14th January 2017, Saturday
-1.1 C to 4.7 C / 3.5 mm / 7.0 hours / W 4
A crisp winter’s day with clear skies throughout and a biting north-westerly breeze, the kind of weather we so little of these days. Cloud increasing overnight however with outbreaks of rain, which was sleety initially, arriving by the end of the night.

15th January 2017, Sunday
1.1 C to 8.8 C / 3.5 mm / 0.2 hours / NW 2
A damp and dull morning with outbreaks of rain &/or drizzle, though by midday conditions would begin to improve, indeed in the afternoon some brighter periods would manage to develop for a time. However this would prove short-lived with further periods of drizzle in mid-afternoon and early evening, and whilst it would become drier for a time, further outbreaks of rain and drizzle would arrive overnight, this becoming more persistent latterly. Milder.

16th January 2017, Monday
2.8 C to 4.9 C / 0.6 mm / 0.0 hours / SE 1
A dull and damp morning with periods of rain and drizzle, and whilst it would become drier in the afternoon, it would nevertheless remain dull and overcast, all in all a day to forget. Overcast and murky overnight with some periods of drizzle at times.

17th January 2017, Tuesday
3.4 C to 6.2 C / 0.6 mm / 0.0 hours / S 2-3
Another dull and overcast day with little to commend it. Remaining overcast during the evening and overnight with conditions becoming murky and drizzly at times. Mucky weather!

18th January 2017, Wedneday
3.7 C to 8.7 C / 0.2 mm / 0.0 hours / W 0-1
Overcast, murky and drizzly yet again with no sign of any brightness whatsoever (no sun has been recorded for three successive days now). Little change in the evening and overnight with some light drizzle at times.

19th January 2017, Thursday
5.8 C to 8.0 C / 0.0 mm / 0.0 hours / SW 0-1
The grim period of ‘anticyclonic gloom’ which has dominated the weather of late continued into a fifth day, with no sun or even a breeze of any kind. Little change in the evening and overnight, though unlike recent nights the cloud base was much higher with no murk or drizzle.

20th January 2017, Friday
5.2 C to 7.8 C / 0.0 mm / 3.2 hours / SE 1
An overcast start to the day, though as the morning wore on it would steadily brighten, indeed by midday some sunshine would even manage to break through with a fine afternoon following, a welcome tonic after all the grim and grey weather of late. Clear spells in the evening and at first overnight, this allowing temperatures to dip below freezing for a time, but cloud would increase after midnight with overcast skies by dawn.

21st January 2017, Saturday
-0.8 C to 5.0 C / trace / 0.0 hours / E 1
A disappointing day with overcast skies and periods of drizzle, the temperature stuggling to just 5.0 C. Little change in the evening and for much of the night, though latterly skies would clear with temperatures quickly plummeting by dawn, eventually falling to a rather chilly -2.4 C.

22nd January 2017, Sunday
-2.4 C to 2.7 C / trace / 1.1 hours / W 1-2
A clear and very frosty start to the day, a rare joy in what has otherwise been another grey and mild winter, though unfortunately the crisp winter sunshine wouldn’t last with grey skies arriving by late morning, the cloud becoming thick enough to produce some spots of rain and drizzle in the afternoon. Feeling particularly raw as well with temperatures rising no higher than 2.7 C. Remaining cloudy throughout the evening and much of the night, though skies would begin to clear later, this allowing temperatures to drop rapidly with another good frost by dawn.

23rd January 2017, Monday
-1.2 C to 4.6 C / 0.0 mm / 4.6 hours / W 1-2
A clear and frosty start again, the ground nice and hard underfoot, and it would remain sunny and crisp for most of the day with plenty of late January sunshine. Clear and frosty at first overnight but freezing fog would form latterly, this becoming thick at times.

24th January 2017, Tuesday
-2.4 C to 6.4 C / trace / 4.8 hours / S 2
Freezing fog at first, this making for another beautiful frosty morning once the fog had cleared by mid-morning, though this transient beauty wouldn’t last long with the frost soon melting in the abundant winter sunshine. Remaining bright and sunny in the afternoon, with clear skies following in the evening, though overnight fog would return. However unlike last night it remained above freezing with a just few patches of ice and frost come morning.

25th January 2017, Wednesday
-0.8 C to 3.8 C / 0.0 mm / 2.7 hours / S 2-3
A foggy start to the day, everything dripping wet, but things would brighten up as the morning progressed with some good spells of sunshine developing by midday. Remaining sunny and bright in the afternoon, though it was on the chilly side with temperatures rising no higher than 3.8 C. Becoming cloudy after dusk with mostly cloudy, and eventually overcast skies throughout the night.

26th January 2017, Thursday
-0.2 C to 0.8 C / 0.0 mm / 0.0 hours / S 2-3
A dull and cold day with overcast skies and temperatures barely rising above freezing, a brisk southerly wind making it feel particularly raw out in the open (up on the Wolds the temperature remained below freezing all day). Back here the temperatures would fall below freezing by 3 pm, and it would remain sub-zero throughout the evening and night, some clearer spells latterly allowing temperatures to dip down to -4.7 C, making this the coldest night of the winter thus far.

27th January 2017, Friday
-4.7 C to 5.5 C / 1.9 mm / 0.3 hours / SE 2
A beautifully crisp and cold start to the day, the ground hard as rock underfoot, with some pale winter sunshine also managing to break through from time to time. However skies would become overcast by 10 am, these grey skies bringing warmer temperatures with it, the magical frost soon melting. Remaining dull and raw for the rest of the day, whilst in the evening and overnight outbreaks of rain would arrive from the south, signalling an end to the quiet and frosty spell of weather we have enjoyed of late.

28th January 2017, Saturday
-3.0 C * to 6.8 C / 0.6 mm / 0.4 hours / S 2-3
A dull and grey morning with occasional spells of mostly light rain, though after midday things would brighten up somewhat with even some short spells of sunshine managing to develop in the afternoon. Milder than of late. Variable amounts of cloud in the evening and overnight, though latterly skies would clear with temperatures dipping below freezing by dawn.

29th January 2017, Sunday
-0.1 C to 5.9 C / 1.7 mm / 4.8 hours / NW 1-2
A clear and frosty start to the day with widespread ice making for slippery conditions under foot, though this would soon melt in the abundant January sunshine. Remaining sunny into the first half of the afternoon, though skies would become steadily cloudier with skies becoming grey by dusk, this thickening cloud bringing periods of drizzle and rain during the evening and the first half of the night. Clearing later but remaining overcast and damp for the rest of the night.

30th January 2017, Monday
1.2 C to 7.4 C / trace / 0.0 hours / SE 3-4

31st January 2017, Tuesday
4.2 C to 7.9 C / 15.5 mm / 0.0 hours / SE 3
A mostly cloudy start to the day, the greyness of the morning temporarily brightened by a short-lived fiery dawn sky, though by mid-morning things had once again become overcast with some periods of light drizzle drifting in from the SE.
