HEADLINE: A MILDER AND WETTER MID SPRING MONTH

April 2018 was a milder than average month at 0.8C above the long term mean. Despite this there was some relatively cool weather and a markedly chilly spell right at the end of the month. The month's average of 10.1C was skewed slightly by the very warm if short period around the 18th & 19th. 24.4C was recorded on the 19th which was the highest month temperature. We were spared any air frost this month which is quite unusual and the lowest temperature I recorded through April was on the 1st at 1.9C.
Rainfall was about 20% above the average for April clocking in at 97mm for the month, the wettest day being the 1st when 23mm fell in the 24hr period. There were some dry days of course, 13 of them in fact but at no point through April were there anymore than 3 consecutive dry days.
Winds were'nt much of an issue through the month but there was some windy days. The strongest gusts here in the village was just 23mph on the 18th while on the hills above the village 35mph was reached on the 6th.
Sunshine amounts were 25% down on the average with just 103.8hrs the total for the month. The sunniest day was the 19th during the very warm period when 13hrs and 12minutes shone down on the village. As a reflection of how cloudy a month it was though there were 8 days out of the 30 which saw no sun at all with 5 consecutive days of this between the 8th-12th inclusive.
By far the most spectacular event of the month was the thunderstorm which crossed the area on the evening of the 21st. After a fine and warm day the skies dramatically turned dark in the early evening almost instantly with a torrential thunderstorm with hail, a rain rate of 220mm/hr briefly and many lightning strikes close by over the village crossing SW to NE across us. The lightning continued to be visible on over into the early hours of the 22nd as the storm system affected other parts of the South of England too.
We were spared any fog, frost or snow through the month and any other unusual weather phenomenon for that matter though I should note that at the time of writing this report we have had an air frost on the morning of the 1st of May.
So summing up April was milder, wetter and more cloudy than average with less in the way of the usual Spring mixture of hail, sleet, snow and frost than is normal for this Spring month.

REPORT


The main feature of December 2017 was how wet it was. More of that further down in this report
The month started quiet enough with High pressure in charge down to the South. It was mild enough too with limited night frosts and light winds After some very mild days in the first week with 12.7C reached on the 7th pressure then fell and the weather became a good deal more unsettled and at times wet in the second week with the wettest day of 36.2mm falling on the 10th making it the wettest day of the month. Several other days saw in excess of 10mm and it became rather chilly at times too with the rain turning to sleet and wet snow at times from the 9th-11th and culminating in a sharp overnight frost at -5.1C on the morning of the 12th. Amounts of snow were insignificant though. On the 10th too a gust of wind of 36mph here in the valley was recorded and it became the strongest gust to have occurred this month. Through the third week pressure rose again steadily and the weather dried up. While not overly mild it wasn't that cold either but there was a lot of cloud restricting daytime sunshine and temperatures but the same hindered the formation of night frost and fog. Having said that there were 4 successive night frosts from the 16th-20th. Then in the run up to Christmas the weather turned mild and cloudy again but not much rain turned up until Christmas itself with 21mm of rain on Christmas Day beaten by 23mm on Boxing Day. This very unsettled and often wet theme then continued right up to the month and year end. It did turn briefly colder again post Christmas with some snowfall overnight on the 26th-27th with a light covering for a while before milder air returned from the West.

So in brief December 17th was warmer and wetter than average with the mercury 0.2C above the long term mean. The rainfall was well above average with 173mm falling through the month. Sunshine amounts were close to the December average but with a higher than average amount totalling 11 days when no sun was recorded. Frosts were quite limited through the month due to the unsettled flavour of the weather with Fog too much below average frequency.
January 2018 was a very wet Winter month and somewhat milder than average too.
Temperatures were 0.6C above the long term average for the area with the highest temperature of the month on the 23rd at 13.2C. The coldest night was a frosty -3.4C on the night of the 30th though this is hardly a record breaking cold night for a mid Winter month. There were just 36 hours in the month that saw temperatures below freezing.
Moving on to rainfall and this was by far the biggest feature of the month. Following on from Decembers wetter than average month January is the second consecutive month to carry on that trend with 153mm of rain through the month. On my own records this is some 43mm above the average of my own records for a January month. The wettest day was the 21st when 23mm of rain fell. There was no snowfall to add to this total though some snow flurries did occur on the evening of the 16th.
Winds were fresh to strong at times with some gales but the strongest gust was 47mph on the 24th-all standard stuff for a mid Winter month.
Sunshine was below average too with just 59hrs over the month with the sunniest day on the 10th with 6.3hrs
There was no thunder and lightning this month but there were several occasions when hail fell, namely the 16th, 18th and 19th.
So all in all nothing too dramatic this month with yet again no substantial settling snow over the area mostly due to the almost entire Atlantic dominated weather patterns which adorned nearly all of the month.

February 2018 will be remembered by two factors which dominated the month. Firstly it was a very sunny month and secondly it turned exceptionally cold in the last few days.
Taking the parameters in sequence temperatures were below average by some considerable margin mostly due to the bitter cold end to the month though there was rather colder conditions than average early in the month too. There were a few exceptions with the highest temperature of 11.9C reached on the 19th in a short milder interlude but the lowest temperature of -6.9C was a very bitter evening on the 27th. The average temperature of 3.0C was 2.2C below my long term mean mostly due to a lot of mild February's in the recent past.

Rainfall was a little below average though there were some wet days, the wettest being the 14th when 19.0mm fell. There were a lot of dry days though and these amounted to 20/28 so it certainly wasn't a wet month.
Wind strength was nothing more than average with the highest gust recorded on the 13th when 45mph was achieved
Sunshine amounts though were miles above the average for February thanks to the cold, crisp, sunny conditions accompanying the cold weather at the end of the month. The sunniest day was the 25th when the maximum of 9hrs and 48minutes was recorded. The monthly total was a massive 172hrs and 30 minutes-the sunniest February I have ever recorded.
It was a very frosty month and there were air frosts recorded over 17/28 nights.
The occurrence of snowfall was up on recent years though no settling snow was recorded other than a dusting on the 28th. Snow was recorded falling on 5 days in the month.
There was no fog, freezing or otherwise to report in February, nor was there any thunder and lightning episodes. Hail featured from showery days on the 12th and 15th.
So in a nutshell February 2018 can be summed up as colder, drier and sunnier than average.

So in a nutshell February 2018 can be summed up as colder, drier and sunnier than average.

March 2018 although a Spring month was far from it this year with the significant factors of the month being much colder, very wet and dull. The month started bitterly cold as the dying embers of the very cold spell at the end of February spilled over into March. The lowest temperatures of the month were recorded on the 1st with -5.4C recorded soon after midnight. It was followed by 2 Ice days where temperatures failed to exceed freezing point even by day on both the 1st and 2nd aided by the snow that was lying across the ground at the beginning of March. Things did warm up though soon after with a thaw but temperatures remained suppressed for much of the month really with another cold, snowy period between the 17th-20th of the month with temperatures only just making positive territory very briefly on the 18th. In some of the warmest moments of the month temperatures did make respectability with 13.6C on the 26th which ended up the highest month temperatures occurring just ahead of another cold period to end the month. So with all this talk of cold the average monthly temperatures was -1.9C below the long term mean Actual frost hours for the month were well above average at 118.9hrs.
Moving on to rainfall and you could basically say that through March if it wasn't snowing it was raining as it really was a very wet month. A total of 167mm (6.68inc) of rain fall through the month with the 9th, 11th, 14th, 28th and 30th all very wet days. The wettest day was the 30th with 18.2mm falling in the 24 hour period 9am-9am. Coupled with the rain we had the snow melt water exacerbating the wet sodden ground.

Amounts of sunshine were very limited and it was the dullest March of the millenium with just a pawltry 69.9hrs of sunshine-8.5hrs of that shining on the 26th making it that the sunniest day of the month. The dullest day of the month was the 18th following heavy snowfall but there were many gloomy days at various points through the month.
Winds were less of a feature overall but they did contribute to problems with drifting snow both at the beginning and middle of the month. The strongest gust was 40mph on the hills above the valley on the 14th.
Snowfall occurred with much more frequency than usual with a total of 33cm of lying snow settling over the month though a thaw rapidly followed each snowfall so settled snow was just a temporary problem.
There were no other unusual phenomenon through the month apart from small hail from showers on the 16th & 29th on what was a cold, wet and dull month overall.
