WeatherWatcher: Oct 29 to Nov 18; Ahead - a series of storms

Highlights:

• Sunday, November 6, our first low temperature this fall below freezing, at 29.7ºF!
• Drier than normal weather for this time of year, the past two weeks combined have been less than an inch of precipitation.

Next week (November 12 - 18):

• We are going to have a series of storms move through from the Northwest out of the Gulf of Alaska. Each storm is going to bring a wave of colder air slowly bringing us colder and colder throughout the week. We will be getting rain with each storm.
• Friday however gets very interesting. Cold air in the Arctic and Northern Canada has been building colder and colder the past few weeks. The majority of forecast models now indicate this cold air mass is going to spread down along the British Columbia coast and into the Pacific Northwest. This could be our first significant snow event of the season. I will be watching this closely as the week progresses, please check back here for any updates!
• There are indications also that once this cold air mass has blown through it will open up the door for a much colder long term weather pattern for the Puget Sound region, including Shoreline and Lake Forest Park. I urge everyone to make sure they are prepared for winter weather before the storm warnings come out. Supplies at stores often run out fast the last 3 days before a storm, usually by the time the National Weather Service releases their watch and warnings. Please consider this an early warning that winter weather is on its way soon!
