1. The severe weather is going to return to the northern Plains this weekend. That area of severe storms will spread east across the Great Lakes into the Northeast next week.
2. The tropical low in the Atlantic will swing around the ridge and into Florida and the eastern Gulf of Mexico next week. While I don't believe it will develop into a tropical depression or tropical storm, it will bring enhanced rainfall and gusty winds to Florida Monday night into Tuesday. The system may get drawn up into the trough coming into the East and could come up the East coast next week enhancing thunderstorms.
Pattern this weekend will feature a storm in the northern Plains and up-and-down heat in the East.
The moonson will bring some nasty weather to the Southwestern part of the country.
Watching the system in the Gulf of Mexico for development. Probably a small chance.
Heat builds into the East while the rain continues for the Pacific Northwest.
Erika will have many issues this weekend includng tracking over the islands with big mountains.
