A relatively active northern stream will promote sensible weather across the northern tier states over the next couple of days. Rain showers and isolated thunderstorms focused along a cold front will spread from North Dakota this morning to the Upper Peninsula of Michigan tonight. The once cut-off low over the Central Plains will quickly phase with the northern stream and amplify over the East by Thursday morning. In the meantime, warm southerly advection into the central and eastern U.S. will produce temperatures that are 15-25 degrees above average, particularly for portions of the Great Plains, Mississippi Valley and Northeast. Ridging over northern Mexico will keep temperatures in the southern U.S. relatively warm during this period. Continued troughing in the Northwest will generate cooler temperatures and some snow showers today and Wednesday. Snow showers will be confined to the Northern Rockies with a few inches expected for portions of the Absaroka Range, in particular.
