A Wild Weather Pattern Through Next Week

September 5, 2014; 10:27 AM ET


We have several weather events coming up the next seven days. Outlined below are those events.

1. Heavy thunderstorms will affect the Ohio Valley today then the Northeast Saturday. Impacts of the storms will be strong winds, heavy rains and small hail.

2. Tropical moisture from Hurricane Norbert will continue to affect the Southwest and may even play a role in the heavy rains next week. Through the weekend and early next week, flash flooding will be the issue across parts of Arizona and New Mexico. The battle between the GFS and ECMWF continues on the movement of Norbert. GFS continues to say the storm hits San Diego as a tropical depression. We shall see which model wins.

3. A cold wave will move into the northern Plains by the end of next week. The first frost and freeze is possible for the Upper Midwest and northern Plains.

4. Ahead of the cold wave, heavy rains and severe storms will develop in the Plains Monday and Tuesday followed by the Ohio Valley and Northeast Wednesday and Thursday. Flooding may be the main impact because of the tropical moisture from Norbert getting involved with the front.
