Not much in the way of precipitation is falling across the US tonight, however we do see some snow occurring in the Upper Midwest as a clipper system moves through. The Midwest overall can expect clouds as that system, along with a couple others surrounding the Midwest, move along.
Out West, low pressure is stationed offshore of California. But high pressure systems dominate the region. I wouldn't be surprised to see a few sprinkles out on the Southwest coast of California, but don't expect any rain accumulation.
