No heatwave but weather set to improve

The good news is that the weather is going to improve at the tail end of a cold and soggy July.

The good news is that the weather is going to improve at the tail end of a cold and soggy July.

The bad news is that there is no heatwave on the way despite some long-range forecasts that suggested such an outcome was possible by the middle of next week.

Met Eireann admitted that it got its forecast wrong for Dublin yesterday. Instead of isolated showers, a day-long deluge ensued.

Forecaster Harm Luijkx said there was a north-easterly flow with a long track over the Irish Sea which was difficult to predict. It picked up a lot of moisture and dumped at least 10mms (or almost a half inch of rain) exclusively on the Dublin area.

A similar weather pattern was responsible for a surprise deluge of snow which closed Dublin Airport during the winter freeze.

Last night in Dublin felt like a winter?s night with a near record low for July of 4.7 degrees recorded at Casement Aerodrome with a grass temperature just above freezing.

Dublin recorded a maximum daytime maximum temperature of just 13.7 degrees yesterday while Knock Airport had a maximum of just 11.8 degrees last Sunday.

Fortunately, things have already started to improve. The forecast for the weekend is for tomorrow to be a dry and sunny day everywhere except in the south-west which will see more cloud and drizzle. Temperatures will be between 18 and 20 degrees.

Sunday will be cloudier but dry with temperatures as high as 22 degrees.

Next week is forecast to be ?reasonably good?, according to Mr Luijkx who cautioned that it is only going to be exceptional by the standards of the weather that preceded it.

?Temperatures will be just above normal in the afternoons, but it is not going to be sunny all the time. It is going to be a mix of sunshine and cloudy periods. No large amount of rain is expected. More like a typical Irish summer, I?m afraid.?

Temperatures will be a maximum of between 18 and 21 degrees.

Earlier this week there was indications that temperatures would be as high as 25 degrees by next Wednesday, but that hope has dissipated, according to the latest forecasts.
