The weather settled down somewhat Wednesday, with only widely scattered showers. It sure felt cool compared to recent days. Vancouver’s high was 54 degrees — a couple below average. At 5 p.m., it was mostly sunny but one could see puffy cumulus clouds in the sky.This same weather pattern will prevail today and Friday as we remain under a cool and unstable air mass. That means that as the sun rises and daytime heating takes place, those towering cumulus clouds will build and some of us may see a downpour or two.I wouldn’t rule out a stray thunderstorm, as well. A few rumbles with hail is pretty typical of early spring weather. Also, watch for rainbows on the coattails of fleeting showers.Some fresh snow fell in the mountains and will continue to fall as low as 2,000 feet above sea level. Amounts will be light. The unsettled weather will continue through the weekend. As I mentioned here Tuesday, it won’t be a washout by any means, and it’ll be more dry than wet.We made it to the halfway point in the month, so how are we doing weather-wise? Vancouver’s average temperature has come up a bit to 45.8 degrees with the warm spell, 0.7 degree below normal. We’ve had less-than-average rainfall with 0.77 inch so far this month. That’s nearly an inch below average. Patrick Timm is a local weather specialist. His column appears Tuesdays, Thursdays and Sundays. Reach him at http://patricktimm.com.
