 As this storm moves to the east, the Plains and Ohio Valley will clear out significantly. As drier air moves in from the north, temperatures will cool off substantially, with highs west of the Appalachian Mountains dropping over 20 degrees in some locations.
High pressure will continue to build over the Plains, helping to reinforce the cool air moving into the east, while keeping skies clear all the way west to the Rockies. The Southwest will also see clear conditions with warm temperatures.
The Northwest will see a fresh round of precipitation on Wednesday as low pressure moves into the Canadian coast. A front dropping south from the storm will send wind, high-elevation snow and heavy rain to the region. Precipitation will drop south into the northern portion of California later in the day, moving through to the central coast overnight.
