Once again, under the influence of a broad trough of cool air from the north, a clear sky permitted overnight lows to drop close to freezing in many areas of the Southern Interior this morning:
Kelowna Airport 0.6C
Princeton Airport -1.8C
This time of the the year, clear skies, no wind and cool temperatures is the recipe for morning fog, so be aware of the potential for slippery roads and patchy poor visibility on your morning commute outside of major cities.
Our trough of cool arctic air is digging southward into the Western US and the flow around that feature is nurturing the development of a significant weather system over the American Rockies. Lows will spin up and exit this trough northward up into the Canadian Prairies over the next day. Sheltered for the most part by the mountains to the east, South Central BC will receive periods of showers...
Seasonal temperatures will continue this week with increasing cloud changing to showers Wednesday evening into Thursday morning. Some sunshine to start Friday, then a cloudy, rainy weekend is in store for us as a new system pushes in from the coast.
Fall lawn fertilization is recommended Friday afternoon :)
