April Temperature Forecast/Analysis.

Mothman

Here are what I make out to be high and low temps of the month at synoptic stations. Met Eireann will issue their summary tomorrow.

To add to drama, the highest was 18.1C on 3rd at Kilkenny. Kilkenny closed shortly after, next highest 17.7C at Johnstown Castle also on 3rd, but neither are we usually using this station, 17.4C at Oak Park, next highest 17.2C at Rosslare on 3rd, and finally a station we usually use and still operating, 17.1C at Shannon on 25th.

The min is much more straight forward -2.1C at Casement on 6th.

Deep Easterly

I think we will go with the highest/lowest temp as per the summery MM, regardless of whether we are using them for the overall mean evaluation. Just keeps it simple and at hand.

A quick overview of the month with available data:

Final station means for the month of April 08:



Shannon/Mullingar are estimates, but final values from these station are unlikely to effect the final overall mean, which is a solid 8.1c, and just 0.1c above average. Congrats to Nemoniod, who's guess of 8.2c for this month is the closest to the final figure. Trogdor put up a good fight, and was only 0.2c out.

Final Station Rainfall Totals and overall mean, in order of absolute totals:



In terms of average distribution:



Absolute and average rainfall totals totals for the month indicate that the north-west and northern inland locations received the highest rainfall during April 08. Overall, it was slightly drier than average, with only Belmullet and Claremorris receiving higher than average totals this month.

Temperature chart in order of deviations:



Worked out to be an average month temp wise generally.

EDIT:4.52pm: Update on Station final values: Shannon 8.7c; Mullingar 7.6c

Mean & Deviation remain in tact despite slightly lower mean values from Mullingar and Shannon that was posted in chart above.

Will post up the updated 2008 trend chart later; indications already that we could be entering a warming phase again, but who knows, trends mean nothing.....;)
