Long Range Weather Forecast For Ireland (10 April 2021)


TRENDS for the week of 10 to 16 April 2021

-- Temperatures will average 2 to 4 deg below normal, with a slight moderating trend during the week.
-- Rainfall (liquid equivalent of wintry showers included) will be 25 to 50 per cent of normal, possibly less in the southeast.
-- Sunshine will be about 75 per cent of normal values. Winds generally about average in speed, sometimes dropping off to calm overnight.


TODAY will start out very cold and bright, with a rapid increase in cloud likely before mid-day, followed by outbreaks of wintry mixed showers including some snow and possible local accumulations in central and northern counties. Highs only reaching about 4 to 7 C. The south coast may be slightly more moderate with regard to both temperature and wintry showers.

TONIGHT the wintry showers will die out during the evening, with partial clearing to follow and another sharp frost is likely with lows -5 to -1 C.

SUNDAY will be similar to today in most respects, but the spread of wintry showers will probably be less dramatic and it could also get slightly milder with highs of 5 to 9 C possible.

MONDAY will have some light rain at times across the north, and partly to mostly cloudy skies in the south after somewhat less frosty conditions, lows -2 to +3 C, highs 7 to 11 C.

From then on, high pressure will be fairly dominant with just isolated showers and temperatures edging upwards to values closer to mid-April normals, probably adding 1 or 2 deg each day until reaching about 13-14 C later in the week. There will still be some slight frosts in this moderating pattern. One rather strong front is set to approach western counties late in the week, it may deliver some moderate rainfalls to coastal areas although eventually it will break up in its efforts to push further inland against the high pressure situated further east.

The pattern within a week will become more moderate still and temperatures could be near or even slightly above April normal values by later in the month.
