TRENDS for the week of 8 to 14 June, 2021 --

south coastal counties, closer to average further north and in the east.

FORECASTS
TONIGHT will remain rather close with lows around 13 to 15 C, low cloud or mist and some drizzle in places.
WEDNESDAY will be similar to today with cloudy skies in many areas,
perhaps breaking at times to partly cloudy, and outbreaks of light rain
or drizzle, in a rather muggy southwest flow. Highs 18 to 22 C.
THURSDAY to SUNDAY the pattern remains almost static but there will
likely be somewhat longer bright spells or sunny intervals especially in
the midlands, east and north. It will become a little warmer too with
highs reaching the 19 to 24 C range. Nights will remain quite mild in
the range of 12 to 16 C. Winds throughout southwesterly at about 40 to
60 km/hr, dropping off at night inland to near calm.
Around MONDAY of next week, we're still expecting a change in the
weather pattern although it may take a day or two to consolidate, as
cooler air works its way in from a source more to the west than
southwest, so it will feel fresher and highs will likely fall back to
around 17-20 C. There may be some showers at times with this cooler
flow, and eventually it could involve some heavier rainfalls from more
organized disturbances replacing these weak fronts that have very little
energy this week. Some guidance is going for much cooler weather within
the second week of this outlook.
