Weather Eye: Don’t put those warm-weather plants out just yet


The occasional sunbreaks were welcomed Friday in between the scattered showers that also brought some hail and even graupel to the county. Precipitation amounts were about as planned, a tenth of an inch or so. Heavier showers fell near the foothills.

More snow fell in the Cascades and foothills as a chilly air mass once again covered the area. With clearing skies Saturday night, I expect most of us will have a good frost this morning, with lows in the 20s, which may be a record in some locales in the Evergreen State.

The weather will turn fair with plenty of sunshine and no rain all week into next weekend, as things look now. On Monday morning, another frost will occur mainly in outlying locations. Downtown Vancouver may stay in the 30s. Sounds like a repeat, doesn’t it? The weather forecast the past week or so was easy – cut and paste.

Let’s talk about temperatures this coming week. We will see 70 degrees for sure Wednesday through Saturday. Last week, we discussed 80 degrees. Some forecast models wanted to heat us up. Fine with me. Forecast charts Saturday afternoon showed another cold air mass dropping down from B.C. to our east. If it strays farther east, we warm into the 70s. If it strays westward, we could get east winds and chilly air. Goodbye, 70s and 80s.

We’ll go with a middle-of-the-road forecast for now, with cool mornings and mild to warm afternoons. In Tuesday’s column, we will see how things look as far as warmer temperatures. Again, I will advise you to not plant warm-weather plants or seeds yet, despite it being sunny all week. There’s still snow on Silver Star, and frosts are possible. I usually wait until Mother’s Day to set out tender plants. Keep a weather eye out for the overnight lows.

As of 4 p.m. Saturday, Vancouver is running more than one degree below normal on the temperatures and one inch below average in the rainfall department. We will welcome the sunshine and mild afternoon weather this week and watch for tempering of the overnight lows. Take good care.
