Visual proof of Seattle's 'teeter-totter' weather of late

To say the weather in Seattle has been a little streaky of late would be like saying Russell Wilson was just a little awesome this season.

We all know summer was really, really, dry and then, like a switch, autumn became really, really wet.

But now again -- just like a switch -- we've gone into an extended dry period.

I've already detailed how the first two streaks went but now with this third streak under way, I thought I'd use a graphic to hit home how the weather patterns have taken such a dramatic pivot -- twice -- instead of a gradual transition.

This map below shows the past few months' weather in 90 day blocks -- the first from July 14 to October 11 when it hardly rained. The second is from Oct. 12 to Jan. 10 when it hardly stopped raining. The third is the current stretch from January 11.

It reads left to right for 30 days, then goes to the second row for days 31-60, etc. The red boxes are days that were totally dry, the blue boxes had measurable rain and the light blue boxes are observed "Trace" of rain that didn't count as measurable but meant it sprinkled or something at some point.

Red box= Dry day. Blue box=Rainy day. Light blue=Trace of rain

The period included a summer dry streak of 48 days (second longest) and a current January dry streak that is set to reach 12 days (second longest for January). In between were four rain streaks of at least a week (19 (tie 6th longest), 12, 10 and 8 days) plus additional rain streaks of 6 and 5 days.

Long range forecast models suggest once this current dry streak ends, we get back to some semblance of normal rain...whatever that is these days.
