Discussion
An active weather pattern will grip much of the eastern two-thirds of the nation over the next several days that will include a tropical storm, a severe weather threat from the Midwest-to-Ohio Valley-to-Mid-Atlantic and then a blast of unseasonably cool air for much of the northeastern quadrant of the nation. The tropical wave now pushing over the Gulf of Mexico is likely to maintain a northerly track and reach southern Louisiana by later tonight. After landfall, this tropical system will then move to the northeast and impact the Tennessee Valley and southeastern US with some heavy rainfall later Saturday into Sunday. The remains of the tropical system could then reach the southern Mid-Atlantic later Sunday into Monday with some rainfall and gusty winds. In addition to the tropical activity, severe weather will develop later today across the Midwest/Ohio Valley and some strong-to-severe thunderstorm activity could work its way into the Mid-Atlantic later tonight and Saturday. Looking ahead, the passage of a powerful cold front on Tuesday will usher in another much cooler-than-normal air mass for the northeastern quadrant of the nation and Wednesday and Thursday will be very comfortable days.
