Laois Weather Forecast courtesy of Irish Weather Online
TRENDS for the week of 21 to 27 April 2021
Temperatures will average near normal or within 1 degree where slightly below normal.Rainfall will average near zero to near the end of this period, picking up slightly in the days just after this weekly interval ends. A few parts of Ulster could see 25 per cent of normal rainfall by next Tuesday. Sunshine will average 25 to 50 per cent above normal, except in some cloudier coastal locations. Winds will continue to average only 20 to 40 km/hr at their peak and calm spells at night will be the rule.
TODAY will see some better sunshine in some regions, mostly inland away from cloudier coastal areas. The east coast in particular may see more cloud than sun. Isolated showers are still possible but few places will get more than a trace of rain. Highs near 11 C on the east coast to 15 C near the west coast and in some parts of the inland south and midlands.
TONIGHT will see some clear intervals, fog or mist in places, and lows generally around 2 to 5 C. Isolated patchy ground frost may return.
THURSDAY to SATURDAY will be a pleasant sunny interval for most places, still the threat of some coastal cloud at times, and the same temperature regime as today although it could warm up by a degree or two for all regions. So expect highs 13 to 17 C for most areas, and overnight lows in the range of -1 to +4 C, with patchy frost in a few locations.
By SUNDAY and MONDAY a weak frontal trough to the north will be exerting some influence and spreading variable amounts of cloud into the region. It may lead to some drizzle in north coast Ulster at times, although Tuesday to Wednesday look a bit more unsettled in the north.
Temperatures will be slowly edging back down towards the range of 11 to 14 C by day but nights will not get any cooler due to the increased cloudiness. Then it appears likely that another cold spell will develop towards the end of the month and temperatures could fall a few degrees further with highs possibly not far from 10 C by the last days of April into early May.
This will all end up in a transitional scenario where the cold and blocking get pushed back into the far north by a more vigorous jet stream, some time around the first week of May or possibly a bit later. Some time around mid-May it could be quite a bit warmer than it has been this month.
