Just so the warmth mafia doesn’t misunderstand this, I’m not calling for climate change to reverse or for our climate to stop gradually warming. Don’t worry guys. Maybe some short term alleviation of the western drought or a little more moderation of our summers, though. Even with a warming baseline there is still room for multi-decadal variability.

ICE AGE NOW, GODDAMNIT

Tomorrow could be a really nice rain maker. Could be the biggest daily rainfall since 12/26. My job has actually slowed down quite a bit without much in the way of rainfall this rainy season. April is looking like a good bet to be wetter than January (2.92”) , February (1.98”) or March (2.77”) this year.

Scored two sunny afternoons here between troughs.  Just beautiful today... 55 in North Bend now.  Bring on the rain.   Hopefully Saturday ends up being nice too as the models have been hinting at recently.

Still fairly sunny out here... clouds held off all day.  You can see on the satellite that the EPSL is the last hold out with the incoming front.  18Z ECMWF looks good for Saturday as well.  A nice mix of sunny and rainy days is pretty decent April weather.

Noticeable trend in the models since yesterday to delay the incoming trough this weekend.  The 18Z EPS and control run were again slower than their previous runs.  This trend could mean a nice Saturday and then possibly a very wet Sunday into Monday as more moisture gets pulled up from the SW with a slower moving front.

I keep liking to think this year is like 2012 but the inverse. Instead of moving into the climate regime we’ve been stuck in the last decade, we’re moving back out of it.

I feel like nationally, this cold season has sorta been a hybrid of 2013-14, 2010-11, and 2000-01. Lots of blocking and consistently cold air over large portions of the country, but more West-focused this winter.

The interesting thing about March 2012 is that it followed a blowtorch winter for much of the country, and was actually a furnace of a month for anyone not on the West Coast. If it was a harbinger of summers to come, definitely does look different this year! Despite being similar-ish at Andrew's place.
