Rainfall/Drought Watch 2020

40.1mm at Dunsany up to midnight 18th of June. Since yesterday we can probably add another 20mm to that total.

January: 55.1
February: 157.1
March: 47.1
April: 19.3
May: 14.2
June: 40.1 (up to the 18th).

I can see our June total getting close to 100mm over the next week by the time we include the rainfall of the past 24 hours, this weekends rain and more rain possible in the first half of next week. I doubt we will catch up on February's big total but I'd say beating every other month so far this year will be an easy target. Looking at last June, one of my least favourite months ever, it is possible we could beat June 2019 for rainfall before months end.

June 2019 was a horrible month here and just looking at that month, Dunsany managed 78.1mm of rain in June 2019 and had an average mean temperature of 12.8C, this temperature was in the 11's for most of June due to 3 weeks of cooler than average temperatures and got helped considerably in the final week of June when temperatures rose into the low 20's at times.

The mean temperature for June has improved alot over the past week. Last week just at the end of the cold spell we were over a degree below normal sitting at 11.9C. Today we are sitting at 13.1C, that's +0.1C above average. I think the mean may come down again slightly over the next week with all the dull, cool and wet weather before rising again later next week.

So far this June is almost identical to June 2019, we've getting a fair amount of rain, we've had cold spells and not that much in the way of sunshine with the exception of about 3 or 4 days. The only difference is the cold hasn't been as prolonged as last year. The temperatures since last Saturday have recovered our mean back to normal values after a cooler than average first 2 weeks of June. Will be interesting to look at the total for June 2020 at the end of the month and compare both Junes off each other.

latest models going for a real shift in rainfall distribution over the next week. For the past 2 weeks rain has mostly been focused in eastern areas due to the easterly winds, but the winds have now shifted back into the west.

Areas in the west which currently are still experiencing low levels of rainfall will certainly make it up over the next week.

Eastern areas which have experienced a good deal of rain over the past week will start to dry out from tomorrow after tonight's rain band clears.



If the model is correct most of the rain this week will fall along the west and north-west as higher pressure keeps many parts of Leinster and Munster dryer over the coming week.

I thoroughly blame you with your doom and gloom forecasts

thankfully it won't be all doom and gloom over the coming week, we should have a few dry and warm days later this week which will be a break from all the rain.

It does look like this is going to be a wetter June than last year, particularly in eastern areas which have already seen alot of rain this month. Western areas will be catching up this week but even there it should become dryer from Wednesday if only for a few days. If the charts look unsettled I just call it as I see it and if it looks like we are entering a a warm and dry spell i'll go to town on the warm and sunny weather.
