Weather Eye: Weather to stay cool, dry, just right for picking out pumpkins
Tuesday, October 25, 2011
There was most likely some frost on the pumpkin Tuesday morning in some locales around Western Washington and another chance Wednesday morning. Cool dry air is a good ingredient to lower the dew points and quickly help the heat in the lower atmosphere escape out into space during the night.
Man, I have seen several flocks of geese heading south the past few days. Annual migration, I know, but things have been cool up north so they are getting while the getting is good, I think.
Looking at computer models for the first week of November and it is still looking like a good cold and wet period with low freezing levels. If all pans out we could see rain/snow mix down to quite low elevations. The storm track will slide south of us into California, keeping us on the chilly side of things. Of course that’s a ways out, but it’s a good reason to keep a good weather eye on the horizon.
Officially, Vancouver has yet to record a freezing temperature, but for the inner city the average first frost can be as late as Nov. 1. We are running about 2.5 degrees above average on the mean temperature and more than a half-inch behind on the rainfall. Unless we get a soaker on Halloween, we will most likely end up below average for October.
Still great weather this week to get out and let the kiddies pick up some pumpkins. The weather should stay mostly dry even though we’ll see some clouds and maybe a sprinkle later in the week — overall, kind of like last week.
The Oregon Chapter of the American Meteorological Society will host the annual “What Will the Winter Weather be Like?” this Saturday. It is a day packed full of events and speakers and should be very exciting and informative. I will have all the details in Thursday’s column. It begins at 10 a.m. Saturday at OMSI and goes until 3 p.m. Come early to get a good seat; they are expecting a packed auditorium. The event is free.
