More showers and thunderstorms this weekend which can produce heavy rains again.
This upper air map shows (1) there is no strong heatwave ridge over the Midwest or Northeast any more and (2) a broad trough populated with smaller disturbances will move from the Mississippi Valley to the Appalachians by Sunday.
Fireballs were caught on video over California last night. Meteor activity is heating up with the peak of a shower tonight. The Perseids will be the strongest meteor shower in years when it peaks in August.
A system that started in the Gulf of Mexico is coming northeast and will bring a swath of heavy rains.
Soaking rains will bring heat relief to parts of the Southeast over the next several days while parts of the Carolinas into the Deep South keep on roasting. Florida will see fairly typical summer weather except for fewer than usual afternoon thunderstorms. A new surge of heat will build in the coming days in the middle of the nation. The tropical East Pacific is quieting down somewhat but the Atlantic is starting to look more interesting.
