Our precious time outdoors in daylight is rapidly decreasing. We stand to lose an hour and a half of daylight between now and mid-November when the sun will set at around 4:30 PM. Not until the winter solstice on December 21 do we start to see the daylight hours increase, allotting more sunlit time outside.
Mostly cloudy conditions may shield the sunset at 6:10 PM this evening. Can't rule out a few sprinkles out of the clouds today, but chances are your backyard will stay dry this afternoon. Scattered showers develop tonight through Wednesday from the first of two storms that will bring much colder air and an end to the growing season by the weekend.
We'll wake up to patchy frost on the pumpkins Thursday morning, especially in the low-lying areas where temperatures will bottom out in the 30's. Brrr. Turning even colder Friday as a strong cold front drags modified arctic air into the Pacific Northwest. While a cold rain looks to overspread much of Puget Sound, a heavy snow will develop over all the mountain passes Friday night. A plowable snow is possible above 2,000 FT (including Snoqualmie Pass!) into Saturday morning making for winter-driving conditions for those with weekend travel plans.
Sky conditions clear quickly in the wake of this fast-moving storm. Freezing conditions and a widespread frost could impact all of western Washington Saturday and Sunday night, thus bringing the 2020 growing season to an end.
Now is a good time to winterize those pipes, pick the last remaining vegetables from the garden, and cover any outdoor sensitive plants. Winter is coming.
