Break out your ice scrapers. Bellingham area could see its first frost
As Fraser winds blow cold air south from British Columbia, a high-pressure system is bringing clear skies to Western Washington over the next few days.
That fall weather pairing could mean frosty mornings for Bellingham and parts of Whatcom County. The North Cascades saw its first significant snowfall over the weekend and temperatures were in the 20s early Monday, National Weather Service forecasters said. In Bellingham, the mercury hovered in the 40s.
“Cool and dry conditions are expected on Tuesday with offshore flow persisting across Western Washington and weak high pressure building into the region. This drying trend, combined with decreasing cloud cover, will make for rather cool nights across the area and will bring the potential of frost to develop across portions of the interior lowlands, especially in sheltered areas away from water and areas near the Cascades, on Tuesday and Wednesday mornings,” the weather service said online.
A frost advisory in effect through Tuesday morning, the National Weather Service said.
This week’s nippy weather is on track for the area’s first frost, according to Plantmaps.com and the Old Farmers Almanac, which track growing seasons and first and last frost dates for gardeners nationwide.
Plantmaps shows Bellingham’s first frost about Nov. 1-10. It sets Oct. 21-31 for the first frost in Ferndale and Lynden.
The Old Farmers Almanac sets Oct. 26 as the average first frost date in Bellingham.
