WeatherWatcher: Cold and a chance of the S word

Sunday, November 22, 2015

Forecast: We have a modified arctic cold front sliding down the coast of British Columbia. There is a lot of cold air behind this front but it does not look like at this time that it will arrive during or before the precipitation does. So this actually looks like almost a carbon copy of what happened last year in November.

The little snow of November 29, 2014
Monday afternoon rain is expected to pick up, with not much more than a quarter inch of rain. Monday night the cold front passes and some of the cold air starts to make its way into the region. Snow is expected to mix with the rain after midnight with no accumulations.

Tuesday we are expected to see some hit or miss rain or snow showers, but it's going to be marginal at best. The real cold air arrives Tuesday evening, bringing our low temperatures into the 20's.

By this time the air is expected to dry up too much to allow any precipitation. Cold and dry air is expected to last through the next weekend as an upper level high pressure system parks over the Western Canadian coast blocking the passage of any Pacific storms.  Daytime highs in the upper 30's - low 40's, with lows in the 20's.

Bottom line is I am not expecting anything more than a trace, and if we get any at all most of it will probably melt off during the daytime with the exception of some sheltered spots. The big story here will be that we will have our first solid freeze at least during the overnight hours for several days through the holiday weekend.

Last week's wind: Though an impressive storm, Shoreline and Lake Forest Park were not hit as hard as some other areas were in the region on Tuesday. The peak wind gust I found in the area was at the North City Elementary weather station clocking winds at 37mph in the late morning hours. Power outages did not appear to be very wide spread or long lasting within the city boundaries.
