-- Temperatures will average near normal values, generally 1-2 above normal but quite cold around Friday.
-- Rainfall will slowly return to the weather picture and by end of this
interval may have reached near normal at least in the west, possibly
50-75 per cent of normal for the east by then.
-- Sunshine will only reach 50 to 75 per cent of normal. This current
regime of very light winds will slowly be replaced by more moderate or
average range of wind speeds and after that, quite windy conditions by
Thursday on.
FORECASTS
TODAY will be cloudy with a few breaks, generally dry with a slight
chance of light showers in the west, and highs in the range of 12 to 14
C.
TONIGHT will be overcast with lows near 7 C.
TUESDAY will be mostly cloudy, moderate south to southwest winds will
set in by afternoon, and some rain will arrive in the west around
mid-day reaching the east by evening. About 5-10 mm amounts are
expected, with highs in the range of 13 to 16 C, mildest inland
southeast.
WEDNESDAY will be partly to mostly cloudy with a few showers and moderate southwest winds, lows near 6 C and highs near 14 C.
THURSDAY will become more windy by afternoon and evening with rain at
times, 5-10 mm amounts expected, and while temperatures may start out
relatively mild, it will turn colder late in the day, highs near 12 C
mid-day then falling to 4-7 C.
FRIDAY will be windy and quite cold for time of year with passing sleety
or even wintry showers, some chance of snow on hills in the north and
west, lows near 2 C and highs near 7 C. Winds southwest to west 50 to 80
km/hr.
SATURDAY and SUNDAY both look rather windy with intervals of rain
although some dry spells too, milder again with temperatures recovering
to around 14 C, winds south-southwest 70 to 110 km/hr at times, and risk
of strong wind gusts developing in exposed northern areas.
This windy regime is expected to moderate by Monday with the southerly
flow becoming more westerly and temperatures near 12 C. Later in the
week towards the Easter weekend the current indications are for
improving weather due to high pressure being near Ireland by mid-week
on, details a bit uncertain with some indications of the flow turning
southeasterly but staying fairly mild.
