Top temperatures of 21 degrees have been forecast for this week

"Noticeably warmer" weather will be felt later in the week.

Following a swift drop in temperatures in recent days, Met Éireann has revealed that summer may not be over yet – as one last spike of warmth is awaiting us this week. Monday morning started off chilly with highs of 12 - 15 degrees forecast, but it seems that the weather is expected to get gradually warmer as the days go on. https://twitter.com/MetEireann/status/1044129447119663104 Tuesday will see the west and northwest of the country affected by patchy rain and drizzle but elsewhere it will remain "largely dry for the day". Highs of 13 to 16 degrees are forecast in fresh southerly winds. Wednesday brings with it "plenty of cloud" but warmer weather with top temperatures of 17 to 21 degrees in moderate southwest winds is forecast. Temperatures are once again set to drop as we go into the weekend with hazy sunshine, thicker cloud with patchy rain or drizzle and temperatures of 15 to 19 degrees forecast for Thursday. And as for the weekend, Met Éireann says: "High pressure looks set to remain the dominant feature of our weather over the weekend with a good deal of dry weather across the country. However, it looks set to be rather cool and there is the chance of a few passing showers."
