PORTLAND, Ore. (KOIN) – When was the last time you could remember such a dry stretch during one of our most rainy months of the year?
A dry week of weather to start off November seldom happens. The last time a November started out with a totally dry week at Portland Airport was in 1957, which was the driest start to November on record, according to the National Weather Service; the dry spell was broken that year on the 10th, when it rained .45″.
We are currently forecasting dry weather until Nov. 10 as well; however, that forecast may change over the next few days.
More recently, we’ve had some dry stretches in November of a similar fashion. In 2009, we were dry for the first nine days, with a few trace measurements earlier in that period.
We haven’t had rain since Oct. 25, and that was just a quick splash coming in at .04″. We are currently on a nine-day dry stretch with potential for another six days. That is quite the timeframe to avoid rain in the fall, which is when we usually see the jetstream become more active and at least some sort of rain will make an appearance.
So what is the reasoning for this? A massive ridge of high pressure over the Pacific Ocean. The storm track is being pushed to the north and around the Pacific Northwest.
