Dense fog shrouded our region Monday morning, more reminiscent of autumn than spring. Quite unusual for April, I would say. Regardless, it cleared by noon, and full sunshine helped push the mercury over the 70-degree mark. Vancouver was sitting at 73 degrees at 4 p.m.
Warm weather extended to Puget Sound, with neighborhoods around Seattle bumping the 70-degree mark. As of 5 p.m. Vancouver reached 74 degrees. Let’s see, that would be the warmest since Oct. 22, when it was also 74 degrees.
After a little rain today high pressure builds again for mostly dry weather through the weekend — nice for spring break. We are getting to the date for the last average frost for most of the inner city of Vancouver. That is a guide, not a guarantee the risk is over. If you set out tender plants be ready to cover them at night if we get a passing cold air mass.
The outlying areas of the county generally see frost into May, so warm weather garden crops wait until Mother’s Day for planting. I used to always go by the snow on Silver Star Mountain to our east, but this year there isn’t much snow at lower elevations so that may not be a reliable factor.
