Daily briefing - Staying busy across northern tier

The U.S. northern tier from the Northwest to the Northeast will have the most active weather today as several winter systems roll through. The rest of the U.S. will be quiet. This is included in today's daily briefing, published every weekday at 5 a.m. ET.

A quick-moving winter storm is rolling across the central Great Lakes and into the Northeast today. The WeatherRadar shows it bringing a wet snow to the Great Lakes, the northern Appalachians and the interior Northeast. Rain will move across the Ohio Valley and the I-95 corridor later today.

In the wake of this system, a reinforcing shot of Arctic air will dive across the northern Plains and the Midwest. The TemperatureRadar shows today's highs will be in teens and 20s across the northern Plains and Midwest, but these will be early in the day as the cold air causes afternoon temperatures to plummet. Tonight's lows will be in the single digits to near zero.

The Northwest will remain busy today, too. Another wave of moisture arriving off the Pacific will bring heavy rain to the Northwest and northern Rockies, with snow falling in the highest elevations of the Cascades and northern Rockies.

The rest of the West, the southern Rockies, southern Plains, South and Southeast will be sunny today. Highs will be in the 50s and 60s across the southern tier, with a few 70s in southern California, Texas and southern Florida.
