Showers and storms will continue to shift east ahead of an advancing frontal system moving quickly from the Midwest into the eastern U.S. later today. Some of these storms may become strong to severe, particularly in the Chesapeake Bay-Delmarva region, where the Storm Prediction Center is highlighting the threat with a Slight Risk for severe thunderstorms on Tuesday. The front is expected to clear the Northeast and Mid-Atlantic coast, with drier air spreading across the region Tuesday evening. The front is expected to stall from the Southeast back into the southern Plains where it will remain a focus additional showers and storms through the middle part of the week. Elsewhere, a frontal boundary draped along the northern Rockies will support periods of snow with significant accumulations possible across the northern Idaho, western Montana and western Wyoming ranges. An upper level disturbance moving east across the central Rockies will introduce some wintry weather to the central Plains on Thursday. Colder air is forecast to spread southeast from the northern High Plains through the central U.S. over the next couple of days. On Wednesday, daytime high temperatures will remain well-below normal across a large portion of the Plains, including areas as far south as the southern High Plains. By Thursday, the colder air will begin to extend its reach further east into the Mississippi valley. Dry weather will prevail from California through the Great Basin and Southwest. A Fire Weather Watch is in effect beginning Wednesday for a large portion of interior northern California, where gusty winds and low relative humidities will bring an increased fire weather danger.
