**GFS MODEL SHOWN HIGH PRESSURE BUILDING AT THE END OF AUGUST AND THE START OF SEPTEMBER**

At the end of this month different weather models suggest that looking ahead to next week the trend seems to be increasingly towards high pressure building across Ireland and the UK.

GFS model outlook

The latest GFS weather model has high pressure building at the end of the month across Ireland with a area of high pressure from the Azores (Anticyclone) moving up and centering itself across Ireland and the UK leading to a much drier spell of weather over the last few days of August and over the first week of September meaning it would start of a dry Autumn.

ECMWF MODEL OUTLOOK

The Latest ECMWF model also shows High pressure on the move from the Azores at the end of the month in the direction of Ireland and starting to possibly build across the country leading to a drier and possible warmer start to September.

THE GEM MODEL

The GEM model is even more interesting looking for the end of the month due to where the high pressure is centered over northern parts of Ireland, the UK into Scandinavia. If this was to happen then much warmer air would be able to move in from mainland Europe with temperatures in the mid Twenties.

ANTICYCLONE - HIGH PRESSURE

An anticyclone is a region of high atmospheric pressure relative to the surrounding air, generally thousands of kilometres in diameter and also known as a high or high-pressure system. Anticyclones appear on weather charts as a series of concentric, widely spaced isobars of 1000 mbs and above. The roughly circular closed isobar at its central region indicates the area of highest pressure.

THE JMA MODEL

The JMA model also shows the same as the other 3 models I have shown above with high pressure looking likely to build at the end of August

From my last update on Sunday when I talked about the signs of high pressure building on a few of the models with some having a mixed view about this well this is a much welcomed sign today with stronger outputs from models of high pressure building and drier spell of weather developing for a number of days again over the start of September. How warm it get is yet a question that will have to be answered as this will depend the strength of the high pressure and where it is centered. If the high centers itself of to the north of Ireland and the UK then this will allow warmer temperatures.

So just to finish up saying that its great to see 4 big models showing the same output which really gives strong hope of this pulling of at the end of this month.
