After an active stretch of weather in the central and eastern U.S., relatively quieter conditions are expected across much of the Lower 48 through for the latter half of the week. As an area of low pressure tracks northeast along the coast, rain is expected to continue into the evening hours across the Northeast. Showers and thunderstorms are forecast to develop along the low's trailing cold front at pushes east across the Mid-Atlantic, while sagging south from the Southeast and Gulf coasts this evening. Some of the storms developing over the Mid Atlantic region may become strong to severe, producing strong, gusty winds. On Thursday, shower and storms are forecast to continue across the Florida Peninsula as the front drops slowly south across the region. Some of these storms may become strong to severe as well, producing hail and strong, gusty winds. Behind the front, seasonable to below-normal temperatures will spread across much of the eastern U.S. on Thursday, with average to below average temperature continuing through Friday. Father west, a weak upper disturbance is expected to support shower and thunderstorm development over the central and southern High Plains through this evening. There is an isolated threat for severe wind gusts and large hail with these storms. Then on Thursday, a system moving east across the mid Mississippi Valley into the Ohio Valley is expected to produce showers and thunderstorms across the region, with some potential for strong, gusty winds and large hail along its advancing cold front. In the West, a well-defined cold front is forecast to move into the Northwest on Thursday. Widespread precipitation, including some high-elevation mixed precipitation, is expected as the system pushes across the Northwest into the northern Rockies late Thursday and Friday. Ahead of the front, above normal temperatures are forecast to continue across much of the West through Thursday. Much cooler temperature will spread across the Northwest on Friday, as above normal temperatures continue across much of the Great Basin and Southwest, while spreading east from the Rockies into the High Plains.
