There's the ever popular "don't like the weather, just wait 20 minutes" but in Western Washington, the adage should be "just drive 20 miles... or less."
A distinct warm front sat right over the North Sound Tuesday evening, bring a stark difference in temperature that if you were to drive from Seattle to Everett on I-5 , you'll have wondered if you entered some sort of meteorological portal around Shoreline.
On the south side of the front: Gusty south winds to 30 mph and very mild temperatures. Boeing Field sat at 61 degrees at 6 p.m. while Renton was at 58 and the University of Washington was 57.
Just a few miles north, the wind was much lighter and out of the due north, drifting by at times around 3-8 mph. Oh, and temperatures were only in the mid 40s. For official stations, Everett's Paine Field was at 46 degrees and it was 42 and raining in Bellingham.
With the map above you can find exactly where the frontal boundary sat -- just north of Lake Washington.
Here is a closer look, circling the two temperatures and drawing a rough red line through the warm front boundary:
Look at the site just north of Kenmore -- 57 degrees and south wind. Just north in Bothell -- 47 degrees and north wind.
So, just like choosing salsas at your favorite restaurant -- you've got a choice of mild or (relatively) hot by just driving a few miles!
