Dry air expanding south from Canada will allow sunshine, low humidity, moderate temperatures and calm conditions to prevail on Friday from the Ohio Valley to the Middle Atlantic and New England. Warm, humid air will persist from the lower Mississippi Valley to the Southeast coast. Spotty thunderstorms will develop in the afternoon and linger into the evening.
Heat is expected to build from Texas and the southern Plains to the central Plains. The hot air will expand across the Midwest this weekend and briefly reach the Northeast by early next week. North of the air mass, severe thunderstorms will stretch from the northern Plains to parts of the western Great Lakes.
Dry weather and some sunshine will continue from California to Washington state. Spotty showers and thunderstorms will develop over the northern and central Rockies. Moisture from the tropical system formerly known as Hurricane Bud will cause showers and thunderstorms to spread north into Arizona and New Mexico. The rain will be beneficial for parts of the region affected by drought and wildfires. Still, the rain may be heavy enough to cause flash flooding over the weekend.
