Models and most forecasts are showing potential for record-breaking heat in the time frame of Sunday 17th to Tuesday 19th in the UK and possibly also in Ireland (more likely to be confined to Sunday-Monday here).
This contest will be mainly about the maximum to be recorded in Ireland and I have widened the net to 16th to 19th just in case. No need to specify locations or times but mention them if you wish. Optional, add a value for the UK, again timing and location not required.
Note __ the contest closes at noon Saturday, any entries time stamped after that will not be ranked.
Regarding the UK portion of this, there was a similar contest (already closed) on Net-weather and yours truly is in with 40.3 which I said would be on Monday in Herts, reason being that the contest when announced cut off the time on Monday so if the peak is Tuesday that will be too bad for the entrants. I would say from a casual reading the consensus of about 100 entries is around 39 C. In our version of the contest you have Tuesday available to consider.
The Ireland portion of this (or the main event) will be based on official reporting stations only, as listed on the met.ie website and as normally shown under current weather and then yesterday's weather for daily summaries. This may be a moot point because it's hard to beat two or three of these locations even on a larger grid of stations. We've had discussions on this forum about Shannon being a bit of a hot spot in situations where it is getting the maximum available heating, due to proximity of sensors to tarmac. Other locations that often run warmer than most would include Mountdillon, Oak Park and the Dublin area stations notably but not always confined to Phoenix Park.
Good luck if you do enter. Once again, the deadline is Saturday at noon (the highest value is not expected to be Saturday but in case it is, I didn't want any nowcasts to win).
