FORECASTS
TONIGHT will be overcast with occasional rain in parts of the north
spreading across most of Leinster towards midnight, amounts relatively
small (2-5 mm) and lows 8 to 11 C.
WEDNESDAY will start out cloudy with a few showers lingering, then gradual clearing will set in, highs near 19 C.
THURSDAY will have increasing cloud with showers by afternoon and
evening, about 5-8 mm of rain expected, lows near 10 C and highs near 19
C.
FRIDAY will be somewhat cooler with scattered showers, and winds turning
to the northeast at 30-50 km/hr. Lows near 8 C and highs near 17 C.
The WEEKEND OUTLOOK is somewhat uncertain, with guidance splitting into
two camps, one saying that high pressure will push in close enough to
give a largely dry weekend with near normal temperatures, but another
thought is that the unsettled weather from Friday will linger especially
across parts of the south. We'll see if this choice is settled in
tomorrow morning's outlook. Temperatures in either case would be
somewhere around 18-20 C.
The end of the month and early July are looking fairly average with
occasional rain but amounts not more than average for the period, and
some settled days in between fronts, temperatures generally near 20 C
for daytime highs.
