Ireland is finally going to see rainfall return to the forecast after over two weeks of dry weather with some areas dry as long as 3 weeks. Even though some areas over the past week have seen some light showers or drizzle a spell of rainfall will push down from the north on late Tuesday night and Wednesday turning heavy over parts Ulster.

At present there is a bit of mix and match on the models where the heavier rainfall will be the latest Icon model has the heavier showers over Ulster with lighter showers making further southwards latest model output can be seen below.

Over the day this rainfall will extend southwards becoming more showery as it does so with drier periods from time to time too. heaviest of the rainfall will be in the north and northwest with heavier burst also possible for a time in some western areas over the morning. 

The rainfall amounts due on Wednesday is nowhere near enough to help Ireland recover from drought conditions or to fill reservoirs. Ireland would need a week worth of heavy rainfall or downpours to recover fully but with this rainfall especially for northern areas who will see the heavier burst it will reduce the risk of gorse and wildfire as there is a lot of dry tinder at the moment nationwide.

There will be a full break down in the weather at the weekend or just after with a westerly airflow and weather front coming in of the Atlantic again next week bringing rainfall at times this may well be short lived as I expect another warm and dry spell to develop again at the end of July or around the start of August.        

I will have another update on the risk of tropical storm Chris and the likely hood of it effecting us over the later part of the weekend in the next hour and a half.
