 Residual
moisture interacting with a stalled frontal boundary along the coast will
fuel more rain showers and chances of thunderstorms through the afternoon.
To the north of this activity, a cold front will move through the Great
Lakes and mid-Mississippi Valley with limited rain showers during the beginning of the day, while chances of showers persist in the
upper Midwest.
Weather activity will pick up along the tail end of this cold front later in the afternoon as a trough of low pressure begins to form over the Plains. Thunderstorms near and ahead of a low pressure system and cold front associated with this trough extending from south-central Iowa to southwestern Oklahoma may turn severe with large hail.
In the West, rain and high-elevation snow will continue over portions of the Rockies, while light rain showers are anticipated in parts of the Pacific Northwest and northwestern California.
Temperatures in the Lower 48 states Wednesday ranged from a morning low of 19 degrees at
Mount Washington, N.H., to a high of 91 degrees at Imperial, Calif.
