Throughout early fall, Alaska has been oddly warm and pleasant. The cause of the freakishly nice weather has been massive high pressure anchored over and around the state. One of the strongest on record for fall, this sprawling dome of warm air has helped keep the usual transition to cold stunted.

Since days are still long in early fall across Alaska, the sunny September (and into October) skies have also allowed ocean temperatures in the Northeast Pacific to rise significantly, as well. This has led to a return pool of abnormally warm ocean water in the Northeast Pacific known as “the blob," and just in time for Halloween!

But scientists are unsure whether the blob will remain a fixture or fade away. If it manages to linger into the winter, the consequences for the Lower 48 could be profound.

Although the blob is focused over the Northeast Pacific and the Gulf of Alaska, it has played a substantial role in the development of extreme weather patterns over the Lower 48 when it has formed in the past. Generally, it has been linked to abnormally warm and dry conditions in the West, and cold and stormy conditions in the East.
