Weather for Remainder of September

The weather forecast for the rest of September is looking fairly dry overall when compared to normal especially over the South and the East. In recent days temps have been around the 20c mark hitting 22c at times in the South west of Ireland as the final dregs of Summer heat are dragged out.

The second half of September is now close by and this means that the nights are getting longer and the possibility of 20c being reached are becoming less and less likely. Still temperatures will probably stay respectable for the period around the 17c mark but nights have been cool since the start of the Autumn and there was even a grass frost on 12th in parts of the midlands.

Toward the end of September and especially in the period after 20th the West and North will see a lot more in the way of rain with rainfall totals in this period here near or above the seasonal average. The South and East will fare a lot better with rain below average but sunshine totals will only be average for the time of year too.

Dry weather here to stay.

Its here at last and it deserves to be in BOLD. The dry weather that has been championed for virtually the whole seond half of the Summer has finally arrived as planned in September. Now the nights will be chilly in the countryside of Ireland and the UK but the towns and cities will be 8 or 9c as opposed to the 4 or 5c that will be experienced in the country. This weather is going to last too (because its not Summer anymore) as long as 20th September but the most likely period is 15th or 16th

Heres the scenarios:

September 15th or 16th - Weather breaks in North and West 20%

September 17th - 18th - Breaks Countrywide 60%

September 19th - 20th - Breakdown occurs with wind and rain 15%

September 21st onwards - Unsettled weather till the end of the month

UPDATES WILL OCCUR....................

Signs of improvement

All signs are there for an improvement in the weather from next wednesday 9th September. original forecasts pointed to a better picture from 5th September but a "fly in the ointment" Low Pressure intervened and is going to bring some more rain and winds for the next couple of days, although there will be some dry spells as well. Temperatures will be a rather cool 15 or 16c. After this things should pick up with the sun breaking through and rainfall becoming less plentiful and temperatures reaching the Low Twenties. How long this lasts is open to debate but long range forecasts are showing High Pressure to the South and West of Ireland for the Rest of September (and not 500 miles to the South like in July and August).

Summer ends in ... Floods!

After one of the wettest Summers on record, August sure went out with a bang. A whopping 36.7mm of rain fell in Sligo flooding many of the towns roads ("road flooded" signs were everywhere) while at the station in Johnstone Castle in Kilkenny there was 34.6mm. The figure of 36.7mm in Sligo was the wettest day recorded at the weathergossip weather station since its inception at the start of May. It also has made August a lot wetter overall than it had been in the provisional graphs for Summer that are printed on this blog.

September??

Throughout the whole of Summer it has been predicted here that September would bring a lot of dry warm weather. This may be still the case, however the first week will NOT bring any dry days to Britain or Ireland. Apart from some heat in the Southeast of England on 1st September the rest of the first week will be unsettled with wind and rain or showers. It is the period of 7th to 21st September that most forecasters are keeping their eyes peeled to. There are signs of a strong High Pressure Intensifying in these days but whether it breaks the Low Pressure stronghold over Ireland is difficult to tell because this pattern has become so established. There are 2 possibilities

1. High makes meandering apperances and rain interrupts occasionally
Confidence 50%

2. High Pressure becomes firmly established. Little or no Rain.
Confidence 20%

Summer 2009 - Another Wet one

The final results of Summer 2009 are yet to come in but if we look at the results at my own weather station in sligo we can see it was a wet and mild Summer. Temperatures in Sligo were 1degrees above nrmal. Rainfall was 120per cent of average except in July when it was twice the normal and the wettest for 50 years in parts of the East and South. Winds were not such a strong feature except the number of breezy or windy days inceased in August as you would expect. Heatwaves were rare except for a 2 week spell at the start of June and a short period in July at start. The highest temperature of the Summer in Sligo was 24.7c the lowest was 9.0c. The highest wind gust was 43mph and the highest rainfall in a day was 28.4mm on 23rd August.
