After an active stretch of weather in the central and eastern U.S., much quieter conditions are in store for a majority of the Lower 48 through the end of the week. A cold front that currently stretches from the Northeast through the Ohio Valley and eventually into the western Gulf of Mexico is expected to exit the East Coast this evening, while continuing to linger across northern Florida on Thursday. Showers and thunderstorms will be found along the frontal boundary up and down the East Coast. A few thunderstorms could turn severe in the Mid-Atlantic and Southeast, with isolated damaging wind gusts and large hail the primary concern. The Storm Prediction Center has issued a Marginal Risk of severe thunderstorms that extends from Delaware southwestward to the central Gulf Coast. The slow-moving nature of the cold front across the central Gulf Coast could lead to scattered instances of flash flooding today as well. WPC has issued a Marginal Risk of Excessive Rainfall across this area, with a small embedded Slight Risk that includes coastal regions of southeast Mississippi, Alabama, and the western Florida Panhandle.

Elsewhere, a weak area of low pressure and associated cold front is forecast to swing through the Central Plains today and into the Ohio Valley by Thursday night. Only light showers and scattered thunderstorms are expected, with light snow possibly mixing in across the Dakotas this morning. For the Pacific Northwest, a fast moving cold front will produce showers and high elevation light snow between Thursday night and Friday morning, as well as the Northern Great Basin/Northern Rockies by Friday.

Temperature-wise, using Cinco de Mayo standards it will be quite spicy throughout the West and very mild from the Midwest to Northeast through Friday. High temperatures are forecast to soar 10 to 20 degrees above average throughout much of the western U.S. today before the warm temperatures shift into the Intermountain West on Thursday. A few daily temperature records could be set in the San Joaquin Valley as highs reach into the upper 90s. Shifting east, the current warm and humid airmass will be short-lived across the Mid-Atlantic and Southeast this morning as refreshing dry and cooler air enters by tonight. Thursday will feature high temperatures nearly 10 degrees below average from the Midwest through the Ohio/Tennessee valleys and into the Northeast.
