The most spooktacular night of the year in the Lower Mainland may either be bitingly cold and dry or slightly cool and fairly wet.
Starting on Wednesday, Oct. 25, the Metro 麻豆传媒映画weather forecast includes a high of 13 C and an overnight low of 5 C, according to V.I.A.'s Downtown 麻豆传媒映画Weatherhood station.
However, as the Arctic front maintains its glacial grip, temperatures will fall further on Thursday, dropping a couple of degrees to a daytime high of 11 C and an overnight low of 2 C.
Other parts of the Lower Mainland will see a similar trend, although some places will be slightly cooler or warmer than others. For example, Downtown 麻豆传媒映画is slightly milder than Stanley Park, at 13 C and 10 C, respectively.
Outside of 麻豆传媒映画proper, other cities, such as New Westminster, will also see a daytime high of 13 C, while Surrey's East Newton will be slightly warmer, with a high of 14 C.
Metro 麻豆传媒映画weather forecast for Halloween
Environment Canada meteorologist Derek Lee says October has seen slightly above-average temperatures overall but the current Arctic air has made them drop three or four degrees below the seasonal averages.
Autumn is still trending to be warmer than average, and the cold Arctic air is expected to transition to an active storm pattern sometime around Halloween, Oct. 31, he explains.
Warmer than average sea surface temperatures should make conditions milder locally, but the "ridge of high pressure over B.C. is so strong and will likely last until next Tuesday" but could last slightly longer. Due to this, the national weather forecaster can't say with certitude whether the rain will arrive on All Hallow's Eve or the following day.
When it does, however, it will "probably be an actual fall storm," Lee adds.
Until the tempestuous weather arrives, locals can enjoy a stretch of bone-dry, bone-chilling weather through the weekend and to kick off the next working week.
