A cold front will slide off the East coast today and humidity will begin to come down. That large high in center of Nation will move east and give much of the country - east of The Mississippi..great weather all week. Notice the next cold front over Central Canada....it will come south to re-enforce the nice weather in The East thru the upcoming weekend.
This map shows the upper air winds at 18,000ft...the jet stream. The East is under a trof...the Rockies under a ridge. The trof represents cooler air...the ridge the warm or hot air. Don't see this pattern changing much for the next 5- 7 days.
Satellite picture shows areas that Hurricane Center now watching. None of these areas are given any high probabilities....but when you look at the next satellite - off Africa....that system appears more developed. We have seen this so far all season...and then they fall apart. All you can do is watch the tropics...not predict them. Enjoy the drier air....later.
