It’s all over: fall has arrived

A near-record spell of dry weather is coming to an end, with showers forecast to begin on the weekend.

In the past 12 weeks there’s only been 5.3 mm of rain—barely enough to measure.

But, that’s all come to an end.

Today is the last of the sunny, hot days that have been a feature of August, September and the first part of October, with that high pressure system breaking down, and typical showery autumn weather moving in.

Meteorologist Doug Lundquist from Environment Canada’s weather services office in Kelowna says normal rainfall for August is 33.6 mm, while we got only 2.4 mm, and normal rainfall for September is 32.7 mm, compared to the 2.9 mm measured here.

Both featured the second lowest amount of precipitation for as long as records have been kept, with the August rainfall amount tied with 2003, second only to 1998’s 0.4 mm. September’s record was set in 1991 when 0.7 mm of rain fell.

“It’s certainly uncharacteristic to have two second place dry months in a row,” conceded Lundquist, but he couldn’t say whether we set a new record.

A new record high daytime temperature was set Sept. 20, with 27.2 C, second to the 1999 temperature of 26.8 C, and the previous day, the temperature tied for the record set in 1991 of 27.7 C.

The last significant rainfall was July 22, but June was one of the wettest on record, with more than 100 mm of rain, and it featured widespread flooding near Okanagan Lake and along local tributaries.

Daytime highs such as we’ve been experiencing in October are unusual, but set no records and overnight temperatures have been cooler than normal.

Beginning Friday, daytime temperatures will begin to drop, and overnight temperatures will go up, as showers move through the area, Lundquist forecast.

No significant rainfall is anticipated, but he said conditions will be much more damp.
