Looking at the radar/satellite pix this a.m. you can see a couple of areas of clouds and rain from the Gt.Lks to The Northeast. These are the fronts that will bring some real nice weather mid week to Ne & Mid Atlantic.
Weather map shows low pressure in The NE....and once that clears...that High moving into Plains will build east. The following map is the Canadian Model. It's upper air pattern indicates a cooler one for The Eastern Half of the Nation next week......so heatwaves are not seen there.
Over to the tropics....an impressive wave is swirling off The African coast and the hurricane center gives it a 40% chance of becoming a tropical system. Given the present pattern....it would have to move across the So. Atlantic and head for the Southeast. Should it grow to a tropical storm...it would be named Dorian. Later.
