* Predict the IMT (Irish Mean Temperature) which is the average of temperatures at Claremorris, Mullingar, Casement, Oak Park and Shannon. The recent 30-year average for that is 15.1 C. * Predict the MAX (highest temperature at regular reporting sites for Met Eireann as reported on their website under "yesterday's weather"…

Predict the IMT (Irish Mean Temperature) which is the average of temperatures at Claremorris, Mullingar, Casement, Oak Park and Shannon. The recent 30-year average for that is 15.1 C.
Predict the MAX (highest temperature at regular reporting sites for Met Eireann as reported on their website under "yesterday's weather" and confirmed later in their publication Monthly Summary.
Predict the MIN (lowest temperature etc, otherwise same as 2 above)
Predict the PRC (rainfall) as a percentage of normal values averaged for eleven sites, the five mentioned in q1 above and also Malin Head, Ballyhaise, Belmullet, Cork, Valentia and Johnstown Castle.
Predict the SUN (sunshine) as a percentage of normal values, from observations at six locations.
BONUS _ A real short-range challenge for you this time, maximum total rainfall Monday - Tuesday 1-2 Aug as reported by the various regular reporting sites, from 0100 Monday to 0100 Wednesday as the day is actually 00z to 00z and we're on daylight saving time. So to be clear, we're looking for the highest total for Monday and Tuesday at any given location, not the total of the highest daily amounts at two different locations. Will just score the amounts, you can give a location if you wish. There are perhaps two parts to the rainfall event so anyway, I seem to be in some system here where the website is pre-arranging these paragraphs by number, which I had not asked it to do, nor do I have time to decode and change it, the next paragraph I hit will say 7 but there is no actual seventh question ...

Well I decoded it accidentally then, by hitting return twice, no more indented points. Whatever. The deadline is 0300h Monday 1st August. For the bonus, I will try to alert late regular entrants to post as quickly as possible but some reduction of total bonus score may be involved if the rainfall already known to have fallen by their late entry makes their prediction appear more accurate. I will play that as it comes, try to enter this on time. Good luck!

My own entry will occur fairly close to the deadline this time, as for NormaL, their bonus prediction will be the GFS output from the 00z Aug 1st model run.

I was going to post NormaL's prediction from 00z but as half the field have already entered, I will go with the 12z output. The GFS maximum grid point 25 mm is near Mace Head. I would imagine Newport might be the actual location.

Will post updates on actual amounts together with any necessary info on late entrant score capping as needed tomorrow. If a late entry occurs before very much rain has fallen, the cap will be 8/10 as an augmented late penalty. If a late entry can make use of intermediate data, then I will have to assess the advantage gained and remove it from potential scoring.

Interesting track of rain seems a lot coming in line from Mayo to Sligo so may see a high total here in Sligo but Finner may be too far North to report and Markree too far inland so I'll report the Town figure. So far only 1.5mm but its lashing.

M.T. Cranium

Noted some hourly temps at 4 C overnight.

pauldry

Newport reporting 18.7mm on 1500 hourly so a clear lead with about 22mm there so far.

Could be an error though we'll find out later

pauldry

Yes add another 10.7mm and its a case of how much with showers soon following in the clearance.

Jpmarn

Counted to about 35mm rain in Newport that doesn’t include the 1800 report.

Apparently there has already been at least 46 mm rain at Newport. Therefore it is possible to score the bonus question as shown.
