RICHMOND, Va. -- We’ll see an increase in humidity on Friday as the high weakens and shifts east, allowing southeasterly flow to return. Rain chances increase this Friday afternoon and evening due to a warm front lifting northwest.
A deep upper-level trough will develop over the Great Lakes this weekend, with a responsive southwesterly flow across the Southeast and Mid-Atlantic. This pattern will transport seasonally high heat and humidity into the area this weekend into early next week, with a chance for showers and thunderstorms each afternoon and evening.
A disturbance in the south-central Atlantic has a very low chance of tropical cyclone development as it slowly approaches the Windward Islands over the next few days. The disturbance off the west coast of Africa continues to weaken and has only a 20% chance of developing into a tropical cyclone.
