Tut tut LF. However, if you put me on the top of the league, I'll turn a blind eye to your lateness. Brown envolope style..

Steamboat. :pac:

Mothman, do you have any idea on final Mullingar figure for May? just so we can do up final charts and climate stats and stuff.?

Continuing the series on the year of 1986. As you may have read so far, the weather of 1986 over Ireland was marked by below average temperatures in general. So how did June of that year turn out? Well in general, June 86 ended up close to average, which broke the cooling trend of previous months of that year. Here is how the Overall Irish Mean* daily trend worked out:


*Using 5 synoptic stations (Belmullet; Shannon; Malin Head; Dublin and Clones)

As can be seen, the first half of June 86 was quite cool, and indeed, despite finishing off close to average, the O.I.M on no day surrpassed the 61-90 average for this month (when accumulated).

On the other hand, pressure values for the month tended to be slightly above normal in general (between 1mb and 3mb above):



although, as the chart suggests, there was never any very high, or very low pressure values on any day of this month.

Weatherwise, June 86 was quite a wet month, but not exceptionally so. Indeed, parts of the southwest and northeast were drier than normal. Much of the rain that fell came in a series of thundery spells for which June 1986 is noted for. The second half of the month was particularly thundery over many parts of Ireland. With Rosslare and Galway recording 6 days of thunder this month. Dublin, Claremorris and Birr recording 5 days and Shannon, Kilkenny and Belmullet totalling up at 4 days, with only Valentia, Cork and Malin Head escaping with between 0 and 2 days of thunder this month.

Here is some extracts from the Meteorological Service of Ireland's overview of this volitile month:

"Although there were some good sunny days in June, the month was notable for the thunderstorms that effected most areas at one time or another. During the first half the weather was generally cool and unsettled with mostly westerly winds. Around the middle of the month high pressure developed to the east and weather systems affecting us tending to come from the continent.

"This brought a rise in temperatures but also quite an amount of thunderstorm activity. These thunderstorms caused widespread damage and destruction, particularlly on Friday the 27th and Saturday the 28th. In Dublin, about a dozen houses were struck by lightning and one house gutted by the resulting fire.

"Power supplies, transport and communications were disrupted and computers and other electrical equipment knocked out".


What was notable this month also was the how much of the rain fell in showers rather than in frontal bands. The east tended to be wetter in the first half of the month (Casement 29.2mm on the 10th) while parts of the west waited til the last days of June for the highest daily totals (35.2mm on the 30th).

Malin Head, Belfast, Cork and Valentia all remained relatively dry throughout this month.

Highest temperature of June 1986 was recorded at Clones on the 28th (25.5c), while the coolest temperature of the month (1.1c) was felt in Birr on the 11th.



A quick look at temperature anomalies for Western Europe for June 86:



Cool to average in the west, slightly warmer further east. Notable is the coolness of the nearby Atlantic.

Lets hope that June 2008 will turn out even half as exciting as this incredible month...


:cool:
