As if mid-week hailstorms that hit Oregon and Washington  weren’t enough cold for one week.
The week ended with a spring freeze most places in the northwest, including many areas along the coast.
So honestly, how late should this be happening around here? Let’s use Portland as a reference because that’s what easy to find long-term records are based on.

I heard our Koin Local 6 Master Gardner Anne Jaeger say that she waits until Tax Day (April 15th) to roll out her tender plants. Now there’s a tip I can remember!

Heard we were near the record number of continuous frost free days, and that was awhile ago. Had the first frost of the year in my yard, Lacomb, today 11/5/16, 35 degrees F. So, did we break the record? Couldn’t find it listed anywhere. Although it did frost, at 35 degrees F, does it technically count as a frost day?
As an aside, have a very basic question. When on your display of temperatures, it may show 45/35, but is that 45 high for the current day, and actually 35 for the low happening around 5-6 am the next day?
Thank you for your time.

John – it depends on the time of day. In the 7day forecast you’ll see Tuesday’s high and low 45 / 35 for example. That is in fact Tuesday morning’s low (around sunrise as you point out) and Tuesday afternoon’s high. The same is true on the forecast fly around the state where it might say 35/43. Morning low, afternoon high.
Thanks for asking this question as many people do wonder about it!
