Long Range Weather Forecast For Ireland (5 April 2021)

TRENDS for the week of 5 to 11 April, 2021

-- Temperatures will average 3 to 5 deg below normal values.
-- Rainfall will average 25 to 50 per cent of normal, in fact this should be precipitation because part of it could take on wintry forms. The higher portions will likely be in Ulster and north Connacht.
-- Sunshine will average about 75 per cent of normal, somewhat lower in the north. Winds will increase to moderate and remain in that range most of the interval, infrequently gusting to strong levels, and occasionally dropping off to light inland.


will be partly cloudy and very cold with a few more wintry showers in places, some accumulations of snow likely on higher ground in the north. Lows -3 to +1 C. The moderate northwest winds will continue in most places dropping off well inland.

TUESDAY will continue partly to mostly cloudy and cold with scattered wintry showers, moderate northwest to north winds (40-60 km/hr) and highs 4 to 7 C.

WEDNESDAY will turn somewhat milder, after a sharp frost across the inland south under clearing skies. Lows near -3 C and highs near 9 C for the south and some central counties. Further north, due to extensive cloud, the range will be more like 2 C to 7 C, and rain will begin during the afternoon and continue off and on overnight (5-15 mm expected).

THURSDAY will see further showers as this front begins to push south, with lows -1 to +3 C and highs 6 to 9 C. It will begin to turn quite cold again in Ulster by late in the afternoon, and in other regions overnight.

FRIDAY will be breezy and very cold with mixed wintry showers, and highs only 4 to 7 C.

SATURDAY morning could be exceptionally cold if skies remain clear, some guidance suggests lows below -5 C in the inland south and southeast. The daytime hours will remain quite cold with variable cloud and highs 3 to 7 C.

The further outlook at this point calls for colder than normal weather to persist; some earlier hints of a more variable regime seem to have faded in favour of cold dominating and only weak moderations of temperature between intervals of very cool weather (for mid-April). This could continue for at least another week.
