Monday was mostly sunny with the main difference from a couple days ago, it was cooler. At 4 p.m. Vancouver was at 60 degrees. That weak weather system that brought clouds a good share of the day on Sunday left a cold air mass over us. Vancouver had a low Monday morning of 32 degrees which was the first freezing temperature this month for the observing station at Pearson Field.
We will see another frost in most locations early today except the downtown portion of Vancouver should remain above freezing in the 30s. I think we are done with frost until possibly Thursday night.
I mentioned earlier that the latter half of this week would be unsettled with possible showers. Now on Monday afternoon forecast models are keeping most of the rain to our north like it did on Sunday. So, the best chances of any showers would be Wednesday night and Friday night. Otherwise partly to mostly sunny. Good news for those on spring break.
We had our first 70-degree high on Saturday this year. Last year it was on April 18; in 2019, it was early on March 17; in 2018, it occurred on March 12; and in 2017, it took until April 21. So this year was about in the middle range of the past five years.
Monday was the anniversary of the Vancouver tornado that occurred on April 5, 1972. It killed six people and did millions in damage. I remember that day well. I was driving southbound over the Interstate 5 Bridge. It was dark as night and heavy rain and hail. The tornado developed out of a squall line that followed the cold that moved through in the early morning hours.
