December 2010 forecast contest

M.T. Cranium

Showdown at the Last Chance Saloon
___________________________________

Looking through the November forecasts, I can sense a tightening up of the leaderboard as we head into the last showdown of the year ... so get ready and fire your forecasts in before the end of Wednesday 1 December.

Please note, your seasonal forecasts (winter contest) do not carry over here and you are free to predict something completely different here. But if you want to be a hero, repeat your December forecasts here for extra bragging rights on New Years Day.

(1) mean temperature (IMT) for Dec (1961-90 avg is 5.3 C)

(2) highest temperature on met.ie stations for Dec

(3) lowest temperature on met.ie stations for Dec

(4) rainfall (melted precip) as percentage of normal for Dec

(5) sunshine as percentage of normal for Dec

(6) Bonus question -- min and max temperatures at Dublin on 25th.

(7) Three-point super-bonus -- snow on hourly reports any met.ie station on the 25th? (yes, no)

Just to avoid confusion, min and max for the 25th is my way of saying morning low and afternoon high but the answers will be validated by whatever is reported in the 24h period (25th Dec) as the high and low for the day. For the snowfall question, yes is valid if any met.ie reporting station has a confirmed observation of snowfall.

Some may also wonder, what about snowfall, how does that factor into a monthly precip % of normal forecast? Well, snowfall is included in the precip total by virtue of its water equivalent. Let's say there is one snowfall of ten cms. If that melts down to 10 mms then it's like 10 mms of rain fell that day in the precip totals. But if the 10 cms is a dry snow that gives only 5 mm water equivalent, then it's counted as 5 mms of precip.

As always, deadline for entries end of the day on the first of the month, and a penalty applies to any forecasts received on Thursday 2nd, after which no entries accepted.

BTTT for visibility ... quick reminder to regular entrants, this monthly contest thread needs your attention, the seasonal forecast is separate and doesn't count here.
