It will be cold in the Eastern U.S. and wet in the Pacific Northwest as the workweek begins.
A deluge of heavy rain will arrive in the Pacific Northwest early in the morning and stick around all day. Periods of heavy rain will occur for everyone on the western sides of Oregon and Washington. Coastal portions of northwest California will also see moderate to heavy rainfall. Lower elevation valleys will see much less than the high terrain, but at least 0.5 inches of rain is expected. The higher elevations should expect over 2 inches of rain in Washington and central to northern Oregon.
The eastern portions of Washington and Oregon will see light rain with the high terrain of northern Idaho and northwestern Montana seeing rain/snow. Moderate snowfall accumulation is possible on the highest peaks.
A deep cold shot moved into the Eastern U.S. on Sunday bringing frigid temperatures for many, especially with overnight lows the next few days. The interior Northeast and northern Mid-Atlantic will see a weak clipper-type system moving into the region. Northern Pennsylvania, and western New York will see light snowfall accumulation.
A stout high-pressure system will be in place for the rest of the Eastern U.S and Central U.S. This will bring dry weather for the southern Mid-Atlantic, Ohio Valley, Midwest, the Plains, the South, and Southeast.
In the Southwest U.S., it will be similarly dry but with warmer temperatures expected. The Four Corners, Great Basin, southern West Coast, and Desert Southwest will all be dry.
Highs in the teens are likely for portions of the far northern Northeast. Still cold with teens and 20s will be found in the Upper Midwest and rest of the Northeast. Twenties and 30s will be felt in the northern Plains, high terrain of the northern Rockies, Ohio Valley, Lower Midwest, and Mid-Atlantic. A mix of 30s and 40s are expected for the Mid-South, Southeast, Tennessee Valley, and interior Pacific Northwest.
Temperatures in the 40s and 50s will be seen in the central Plains and southern Plains, Deep South, Great Basin, Four Corners and northern to central West Coast. Fifties and 60s are in store for the High Plains, central to southern Florida, and southern West Coast. The Desert Southwest will see the warmest weather in the U.S. with 60s and even 70s in the forecast.
