Unemployed software engineer. "What is that?", you may ask. It's someone who has time to blog about the weather...

Since February this blog featured a polar projection of snow cover in the northern hemisphere. In my part of the world that view is no longer germane. Except on high mountains all the snow and ice are confined north of the forty-fifth parallel. In the eastern hemisphere frozen stuff has retreated north of sixty degrees. Only in Canada around Hudson Bay does snow linger south of that latitude. Folks in Labrador are still waiting for spring. It may be a long wait this year.
Here in the Dry Slot it's time to start looking south for clues to what the weather has in store. While it is still too early in the season to worry much about hurricanes, it will be tropical heat, not polar chill, that drives the circulation in my neighborhood this summer.
There's a literal sea change in conditions in the tropical Pacific. Here's an animated loop from the National Weather Service Climate Prediction Center. It shows sea surface temperatures in the equatorial Pacific Ocean over the last ninety days. Note the shift from blue to orange in the region west of the Galapagos Islands.
