The weather in Charleston is about to take a serious turn—and fast. While this morning’s calm, foggy start might feel like a peaceful prelude to summer, a string of storms is on the way that could flood streets, knock out power, and disrupt travel through Thursday. After days of downpours and stormy skies, the sunshine does return—but not before Charleston weathers the worst.
If you’ve got outdoor plans, commutes, or errands to run this week—read on and plan smart. Each day through Thursday carries its own weather threats.
Storm Timeline: When the Rain Hits and Why It Matters
Tuesday (June 17)
Charleston will feel muggy and mild by mid-morning, with temperatures climbing to 83°F. But don’t let the warmth fool you—showers and strong thunderstorms are set to develop later in the day. These storms could bring:
-
Flash flooding
-
Damaging winds
-
Hail in localized areas
-
Traffic-snarling downpours
The worst conditions are expected after 3 p.m., right as many head home from work.
Wednesday (June 18)
Wednesday delivers more of the same: warm, humid air fueling spot thunderstorms, especially in the afternoon. Highs will hover around 85°F, and while storms won’t blanket the region, any cell that develops could be intense and fast-moving.
Expect:
-
Lightning and heavy bursts of rain
-
Unpredictable storm paths
-
Localized street flooding
If you’re outside or traveling in the late afternoon, you’ll want to stay updated in real-time.
Thursday (June 19)
Thursday could be the stormiest day yet. The air will be heavy, the skies gray, and the threat of widespread afternoon thunderstorms increases. With highs again in the low 80s, and moisture pooling in from the west, Charleston is under a heightened risk for:
-
Severe storm clusters
-
Late-day power outages
-
Multiple rounds of downpours
It’s the last day of the storm train—but also the one that could bring the most damage.
Finally: A Summer Weekend to Look Forward To
Starting Friday, Charleston gets its reward: a break in the clouds and a blast of summer sunshine. Highs will rise to around 89°F, and skies will remain mostly sunny with far less humidity. It’s an ideal setup for weekend festivals, cookouts, and relaxation.
Saturday and Sunday will continue the heat streak, with temperatures in the low 90s, though a brief thunderstorm is possible Sunday morning. Still, the overwhelming theme is clear: after a rough, stormy week, West Virginia will finally dry out.
How Charleston Residents Should Prepare
-
Plan indoor activities Tuesday through Thursday afternoons.
-
Avoid travel during late-day storm windows—especially after 3 p.m.
-
Secure loose outdoor items that could become airborne in high winds.
-
Charge your phones and devices in advance of any outages.
-
Stay weather-aware via local alerts, especially if living near rivers or creeks.
