A WEEK OF HUMIDITY AND RAIN AHEAD

December 12, 2011

Sub-tropical humidity should cover much of the country by the middle of the week. This is in advance of a major trough that is likely to bring rain to the South Island on Wednesday, before moving across the North Island during Thursday and early Friday.

“Whilst the expected rain and extra humidity may be useful for those needing to fill water tanks before the summer holidays, it is likely to be troublesome for horticulturalists preparing for the Christmas rush,” commented MetService Weather Ambassador Bob McDavitt.

“The rain is likely to target the ranges of Westland and Buller, bringing heavy falls from early Wednesday, before reaching the ranges of Nelson, northern and western Marlborough, Mount Taranaki, Northland, and possibly other parts of the central North Island late Wednesday and much of Thursday.”

This trough is already directing a flow of sub-tropical air onto the country, producing increasingly sticky and uncomfortable conditions. As it approaches mid-week, MetService advises people in the above areas to be ready for the possibility of some heavy rain.

McDavitt added, “There is likely to be a southerly change over the South Island by the end of the week, bringing sunnier skies and lower humidity for the weekend.”
