It is the heat there, that is causing so much trouble here.
The surface heat builds big pillows of air above it. Air moves but doesn't move away quickly. Meanwhile, air movement above the ocean begins coming on-shore. Instead of the ocean air going some place where it could bring cooling and rain, it kind of careens around usually heading north.
The Pacific Northwest can't warm up and the middle of the continent (especially to the south) cannot cool down! Sometimes, fairly serious storms occur where all this cool air and all that over-heated air meet.
Much of the US had a really warm winter. Meanwhile, Alaska was tragically cold and stormy.
