Raleigh, North Carolina – Steamy summer heat will give way to drenching thunderstorms across the Raleigh area on Tuesday, July 15th, with the biggest impacts arriving during the afternoon commute. Flash flooding, slick roads—especially along I-40—and potential power outages could disrupt daily life and travel for thousands.
According to the National Weather Service, a 70% chance of showers and thunderstorms will develop after 2 p.m. Tuesday, with rainfall amounts possibly topping a quarter inch in some neighborhoods. City officials urge drivers to reduce speeds on major corridors, including I-40, as intense rainfall and lightning may create sudden hazards.
Raleigh and nearby towns like Cary and Garner can expect storms to linger through the evening. Although most rainfall will be brief, isolated downpours may cause temporary flooding in low-lying areas. Residents should secure outdoor items and charge devices before heading out. The heat index will remain high, so plan for muggy conditions before storms arrive.
Wednesday brings only a slight break, with more scattered storms possible in the afternoon and evening. Thursday and Friday look similar, as daily highs flirt with the mid-90s and humidity stays oppressive. Storm chances remain in the forecast, so keep rain gear handy if you’re heading to local parks or downtown events.
Looking toward the weekend, Raleigh’s summer pattern continues: Highs around 94°F, pop-up afternoon storms, and sticky, warm nights. Sunday could bring the next round of widespread showers, setting the tone for an unsettled start to the new week.
What’s Next:
Thunderstorm risks linger each day through Sunday. Keep checking for new advisories as conditions change. Warnings could be upgraded quickly if flooding or severe weather develops.
