HIGH PRESSURE IN CHARGE = BRIGHTER TODAY, SUNNY & MILDER TEMPERATURES INLAND (FRESH TO STRONG COOLER NORTHERLIES FOR COASTAL CANTERBURY)
(SUMMARY – SUNDAY MORNING 6:45AM).
Good morning. We have areas of morning low cloud this morning and isolated ‘pockets’ of fog about inland basins, but today is going to be mostly sunny under high pressure. Those persistent easterlies will keep Coastal Canterbury cooler, while inland basins and nearby areas will escape the winds and push into the early twenties. Our pick for Sunday is the Mackenzie Country, through the interior or Hanmer Springs, slightly warmer and no easterlies.
RAINFALL EXPECTED TODAY – No rainfall forecast.
BRIEF SUMMARY (MAIN POINTS)
HIGH PRESSURE HOLDS ON – Early next week looks mostly fine and settled, with warmer temperatures and quality sunshine hours but we have a number of fronts of interest as we head into later stages of the week. There is the potential for rain and colder southerlies on Wednesday, Thursday & Friday. Our long range forecasts now covers this in unmatched detail. Make the most of earlier stages of the week. An incoming high late Friday should bring a mostly fine weekend. Traditional 5-6 day Canterbury weather patterns.
At this stage Wednesday looks the wettest day for the reminder of March and we’ll experience our coldest air to date in 2018, with snow around 1200m-1400m. (Rainfall totals could exceed 40mm in grand total later in the week – especially about the Canterbury Foothills).
