**SPECIAL WEATHER STATEMENT**: Earliest Autumn Coldsnap Not Seen Since 1985September 27th, 2009 by Matthew Leach
See? I wasn’t being dramatic!
The National Weather Service in Seattle has issued a SPECIAL WEATHER STATEMENT highlighting the much colder and wetter weather ahead. Daytime highs could top out as much as 10 degrees below normal with wet, breezy and raw conditions in the lowlands and, at times, snowy periods in the mountains as the snow level drops as low as 4,000′.
Many lowland locations have already recorded their first lows in the 30s with daytime highs the past couple of days running below normal ahead of the main event Tuesday.
Forecast models have been really pushing this hard, giving us a string of much below normal temperatures and above normal precipitation for at least the next 10 days. It’s not looking likely that we’ll see rain every day, but just keep in mind it will definitely feel more like fall out there.
Here’s the statment by the National Weather Service:
