Overview

• Above-normal warmth continues Sunday with many areas in the upper 80s to mid 90s and largely dry weather aside from brief, localized morning showers.
• Guidance points to a coastal low bringing increased clouds, drizzle and light showers Tuesday into Wednesday for parts of the Mid-Atlantic and Southeast, with a modest cooldown and track uncertainty.
• A tropical wave near the West African coast has around a 50% development chance over the next week, and forecasters see no immediate threat to the United States.
• Heat and light winds are contributing to air-quality concerns, including repeated ozone action day alerts in the Houston area.
• Persistent dryness and developing drought mean even light midweek rain would help in some regions, while onshore flow keeps parts of Florida breezy with 20–30 mph gusts.
