FORECASTS
TONIGHT will bring intervals of moderate rainfall, 5-10 mm expected, lows near 5 C.
WEDNESDAY will see this rainfall ending during the morning, followed by
variable cloud and isolated showers, another interval of heavier rain
expected by evening. Highs 8 to 10 C in the south but only 5 to 7 C in
the north where it will feel quite cold.
THURSDAY will have an early morning rainfall event of 10-20 mm that
could mix with sleet over higher ground. Some parts of the western
coastal counties may see 20-30 mm rainfalls with this low tracking
through central counties overnight. Strong south to southwest winds for a
time near the southeast coasts, but these will not affect other
regions. Later in the day, partial clearing and rather cool,
temperatures steady 4-6 C from overnight into the daytime hours (except
8-10 C briefly in the southeast).
FRIDAY will see another overnight rainfall to start the day and this
rain could be quite heavy in places with 30-50 mm potential. Winds
becoming strong south to southwest 70-110 km/hr. Temperatures climbing
to 10-12 C and staying in that range to about Saturday morning, with the
rain still going by then.
SATURDAY will start out wet especially in the east, but the rain will
finally end and push east, leaving a partly cloudy day with highs near 9
C.
SUNDAY will have variable cloud, showers, southwest winds 40 to 60 km/hr and highs near 10 C.
The OUTLOOK for next week is for near average conditions to late in the
week, then colder weather returning by the end of the month and
persisting for several days into March.
