April 2016 Weather

A cooler than average month with the mean temperature over a degree Celsius below the 1981-2010 norm, the end of the month being especially chilly with snow settling on the local uplands (above 150 metres), though down here at the weather station itself the wintry precipitation was restricted to just sleet and an hour or so of wet snow on the 26th. Though snow in April is not particularly rare, it was nevertheless the first time since 2013 that snow has been recorded at our weather station during this four month of the year, whilst the date of the last snow, the 26th, might well be a new record for the weather station.

Rainfall wise the month concluded only slightly above the long term average, rainfall for the month coming to 53.2 mm (2.09 inches), about 108% of what would be expected in a typical April. As is normal at this time of the year much of the rainfall came in the form of showers, some of which were quite sharp with hail mixed in on three days, though the wettest day by far and away was the 15th as persistent overnight rain brought 16.5 mm.

Finally sunshine was also slightly above average, this despite a dull first-half of the month in which just 49.9 hours was recorded prior to the 15th, but thereafter things would improve markedly as pressure rose over the British Isles, the second-half of the month recording 107.2 hours and giving a final monthly sunshine total of 157.1 hours, about 103% of the 1981-2010 average.

April 2016 Logbook (click to enlarge)

1st April 2016, Friday
Another frosty dawn but unlike recent mornings it would soon become cloudy and grey with the breeze also freshening, this making it feel particularly cold and raw. Hardly a spring-like start to April! Remaining overcast, cold and grey throughout the day with rain arriving towards the end of the afternoon.

2nd April 2016, Saturday
4.4 C to 13.2 C / 3.5 mm / 3.0 hours / S 2-3
A wet and miserable morning with outbreaks of rain but by midday it would begin to improve with skies slowly brightening in the afternoon. Indeed in the second half of the afternoon some spells of sunshine would develop, and with temperatures climbing up into the mid-fifties (Fahrenheit) it would feel quite pleasant. Variable amounts of cloud in the evening and at first overnight but by midnight cloud would increase with outbreaks of rain for the remainder of the night.

3rd April 2016, Sunday
4.2 C to 14.3 C / 2.1 mm / 3.8 hours / S 1-2
A dull and grey morning, the ground wet after last night’s rain, but towards the end of the morning things would gradually start to brighten up with things improving yet further in the afternoon with good spells of sunshine developing. Feeling quite warm as well, especially in the shelter of the walled garden, with temperatures climbing up towards 15 C. Cloud increasing again in the evening with some rain for a time overnight, and whilst it would become drier by the end of the night, it would remain overcast and murky. Mild.

4th April 2016, Monday
5.9 C to 13.4 C / 1.4 mm / 1.7 hours / S 2-3
A grey and dreek morning with outbreaks of mostly light rain and low cloud, but in the afternoon things would improve with even some spells of sunshine managing to develop by mid-afternoon. However a few light showers would also develop by late afternoon and early evening but these would come to nothing and would soon die out. Clear spells at first overnight but becoming mostly cloudy latterly. Cooler.

5th April 2016, Tuesday
4.8 C to 11.8 C / trace / 0.8 hours / W 4
A mostly cloudy day with some outbreaks of light rain around midday, though in the second half of the afternoon and into the evening it did brighten up somewhat with some late sunny spells. Feeling cooler, especially in the moderate westerly breeze. Variable amounts of cloud overnight with some decent clear spells, though the breeze prevented a ground frost.

6th April 2016, Wednesday
2.9 C to 11.4 C / 0.4 mm / 5.0 hours / W 5-6
A mixed day weather-wise with some good spells of sunshine though in the afternoon a number of showers would also sweep through, one of which produced some decent sized hail for a short period. However it felt quite chilly, especially in the wind which was strong and gusted in excess of gale force at times. Showers dying out in the evening with clear spells overnight.

7th April 2016, Thursday
2.0 C to 11.6 C / 0.5 mm / 4.8 hours / NW 3-4
Another mixed day with plenty of sunny spells but also a few showers, though none of these showers were particularly heavy. However it was far less windy today and as a result it felt much warmer than yesterday with temperatures again in the low to mid-fifties (Fahrenheit). Showers dying out in the evening with clear spells overnight, this allowing temperatures to fall low enough for a touch of ground frost.

8th April 2016, Friday
1.4 C to 13.7 C / 1.7 mm / 6.5 hours / S 2-3
A clear and chilly start to the day with a touch of ground frost in prone locations, but otherwise it was a pleasant spring morning with plenty of sunshine to enjoy. Becoming somewhat cloudier in the afternoon but remaining bright enough with some decent sunny spells at times, though by late afternoon it did become mostly cloudy and it would remain so throughout the evening and night. Indeed by the end of the night periods of rain would arrive from the south. Milder.

9th April 2016, Saturday
A wet morning with persistent rain and low cloud over the moors, and whilst it would remain wet into the first part of the afternoon, conditions would quickly improve in mid-afternoon with some good spells of sunshine developing. It would also feel relatively warm, at least out of the wind. Cloud increasing again in the evening with some rain for a time after midnight but this would clear away by dawn.

10th April 2016, Sunday
A chilly start with low cloud and fog up on the moors but this would soon clear away to leave a largely sunny and clement morning and afternoon, temperatures in the low to mid-teens. However a cool easterly breeze did make it feel a little chilly out in the open. Becoming increasingly hazy in the afternoon and evening with a veil of thin cloud throughout the night, whilst low cloud would again form over the moor tops.

11th April 2016, Monday
3.9 C to 13.5 C / 4.1 mm / 4.3 hours / E 4
A cloudy and grey start to t’ day but from mid-morning onwards it would quickly brighten up with some good spells of sunshine developing, these April rays feeling quite warm out of the brisk easterly breeze. Cloud increasing again after mid-afternoon, this cloud thick enough to produce the odd spot of rain for a time, and whilst it would become dry again in the evening, further rain would arrive around midnight, this being far heavier and more persistent. However the rain would clear by the end of the night but with light winds and damp air it would become misty and eventually foggy by dawn.

12th April 2016, Tuesday
6.7 C to 11.7 C / 4.4 mm / 0.1 hours / W 3
A foggy start to the day with poor visibility, though when rain arrived in mid-morning this mist and murk would quickly lift. The rain would become moderate and persistent for the remainder of the morning and would continue into the afternoon, though by mid-afternoon it would begin to clear away with a largely dry evening following. However it would remain largely cloudy and would remain so throughout most of the night.

13th April 2016, Wednesday
3.9 C to 13.5 C / 1.4 mm / 6.2 hours / NW 2
A clement morning with plenty of sunshine, feeling warmish despite only modest temperatures thanks to the light winds, but in the afternoon cloud would increase from the north-west with some showers in mid-afternoon. Becoming drier by the evening but it would remain largely cloudy with just the odd clearer spell during the night.

14th April 2016, Thursday
4.3 C to 12.2 C / 0.4 mm / 1.8 hours / N 2
A bright start to the day with hazy sunshine, the ground very wet after a very heavy overnight dew, but in mid-morning it would become cloudy and grey as fog and low cloud from the Wolds drifted over. However this soon cleared and for the rest of the morning it would be bright and clement with some good spells of sunshine. Cloud increasing in the afternoon and slowly thickening with some rain and drizzle in early evening, and whilst this would clear by nightfall, it would nevertheless remain mostly cloudy overnight.

15th April 2016, Friday
3.7 C to 10.5 C / 16.5 mm / 0.2 hours / N 3-4
A cloudy and grey morning, the cloud thick enough to produce some spots of rain at times, though it would become somewhat brighter around the middle of the day. However in the afternoon the cloud would thicken again with outbreaks of rain arriving towards the end of the afternoon. This rain would become heavier and more persistent in the evening and would continue for most of the night, this rain becoming a little wintry latterly (the tops of the Wolds saw minor & slushy accumulations). Colder.

16th April 2016, Saturday
1.5 C to 9.3 C / 0.2 mm / 6.6 hours / NW 4-5
A wet start to the day with cold rain, but this would soon clear away with sunny spells developing by mid-morning. Feeling unseasonably cold though with temperatures really struggling, this not helped by a brisk northerly breeze, whilst in the afternoon a few blustery showers also helped to peg the temperatures back even further. Showers dying out by the evening and with the breeze also easing it would become quite chilly under clear skies with a light hoar frost by dawn.

17th April 2016, Sunday
0.2 C to 12.5 C / 0.0 mm / 10.2 hours / W 3-4
A clear and frosty start but in the April sunshine it would soon warm up, any trace of the frost soon thawing. Thereafter the morning would see an abundance of sunshine, and whilst the north-westerly breeze was undoubtedly chilly, it nevertheless felt pleasant enough. Sunny spells in the afternoon with a scattering of fair weather cumulus, though in the evening it would become somewhat cloudier with variable amounts of cloud for the remainder of the night.

21st April 2016, Thursday
0.2 C to 15.2 C / 0.0 mm / 11.2 hours / N 2-3
Another sunny and clement April day with an abundance of sunshine and temperatures a few degrees above average for the time of year, though in the afternoon winds would become more northerly, this adding a slight chill to the air. Variable amounts of cloud overnight with a slight breeze preventing temperatures from falling as low as recently.

22nd April 2016, Friday
2.6 C to 12.5 C / 0.0 mm / 7.2 hours / NE 3-4
A bright day with plenty of sunny spells, especially in the afternoon, though the most noticeable feature of the weather today was the chilly NE breeze, this making it feel much cooler than it has of late. Variable amounts of cloud in the evening and overnight with temperatures dipping low enough for a slight ground frost.

23rd April 2016, Saturday
0.9 C to 11.4 C / trace / 5.7 hours / NW 4
It was a bright but decidedly chilly day with a brisk northerly breeze making it feel particularly cold out in the open.

24th April 2016, Sunday
1.2 C to 9.6 C / 0.0 mm / 4.6 hours / NW 4
Another bright but chilly day with temperatures remaining in single figures throughout, though it was the brisk northerly wind which made it feel especially cold, especially out in the open. However like yesterday there was plenty of sunny spells too and it would remain dry throughout. Variable amounts of cloud overnight.

25th April 2016, Monday
2.5 C to 10.9 C / 1.2 mm / 5.3 hours / NW 4-5
A chilly day with sunny spells and occasional wintry showers, the brisk NNW wind which gusted up to nearly 30 knots at times making it feel especially cold for the time of year. Clear spells for most of the night though latterly sleet and wet snow showers would drift down from the north.

26th April 2016, Tuesday
-0.1 C to 8.9 C / 0.7 mm / 4.6 hours / NW 5
A bitterly cold day for late April with wintry showers throughout, indeed in the morning some of these showers actually fell as snow. However between the showers there were some good spells of sunshine, though the fresh breeze northerly breeze meant it still felt very cold, especially out in the open. Wintry showers dying out in the evening with clear spells overnight.

27th April 2016, Wednesday
0.5 C to 10.0 C / trace / 4.7 hours / N 3-4
A slightly better day with fewer wintry showers and the winds somewhat lighter than of late, but nevertheless it still felt unseasonably chilly with temperatures only just about reaching double figures despite the good spells of sunshine. Clear spells overnight with temperatures falling a couple of degrees below freezing, whilst latterly mist and then fog would also form by dawn.

28th April 2016, Thursday
-2.0 C to 9.6 C / 5.1 mm / 4.5 hours / SW 4

0.3 C to 8.7 C / 3.2 mm / 2.8 hours / W 4-5
After initial light sleet showers had cleared away it would become bright with some good sunny spells for the first half of the morning, though this wouldn’t last with outbreaks of cold rain soon sweeping in from the west. The rain would also be accompanied by some quite squally winds at times, this making it feel particularly cold out in the open. Showers becoming less frequent as the afternoon wore on and eventually dying out by the evening, this leaving a largely fine if somewhat chilly end to the day. Clear spells overnight with a touch of ground frost.

30th April 2016, Saturday
0.3 C to 11.8 C / 0.4 mm / 10.9 hours / W 3-4
A sunny morning with long spells of much welcome sunshine bathing the central East Yorkshire countryside, though in the afternoon a few showers would also bubble up, one or two of which were quite heavy with some hail mixed in at times. Showers dying out by the evening with clear skies developing overnight, this allowing temperatures to fall low enough for a touch of frost by dawn.
