The threat for severe weather and flash flooding across the Mid-Atlantic
was supposed to diminish during the late evening once the sun went down. However, rains and thunderstorms continue to be supported
along the coast and into the Southeast as the front moves off the
Mid-Atlantic coastline overnight tonight.

More moderate precipitation wrapped around the surface low is still possible in southern New England tonight and early Friday morning as well. Behind this system, high pressure will move in bringing cooler and dryer air with it on Friday and into the weekend.

Meanwhile, an upper trough carving into the Northwest U.S. will continue
to bring precipitation to the Northern Rockies on Friday. Once the frontal
system pushes east of the Rockies on Friday, showers and thunderstorms
will develop in the northern Plains and eventually the Midwest. Some of
the thunderstorms could bring some heavier rainfall as well as the threat
for severe weather.

Threat for severe weather is expected on Friday will be across the northern and central Plains. Damaging wind gusts and large hail will be the problem.

Showers and possibly a thunderstorm, then showers likely. Some of the storms could produce gusty winds and heavy rain. Low around 57. Breezy, with a north wind 13 to 20 mph. Chance of precipitation is 80%. New rainfall amounts between a tenth and quarter of an inch, except higher amounts possible in thunderstorms.

Friday A chance of showers. Mostly cloudy, with a high near 73. North wind 11 to 18 mph. Chance of precipitation is 50%. New precipitation amounts between a tenth and quarter of an inch possible.
