Grand Junction, Colorado – A brief break from stormy skies is in store for Grand Junction, but below-freezing temperatures tonight mark a sharp spring chill. While Thursday, May 15, brings sunny skies and highs in the low 70s, residents in surrounding valleys should prepare for freezing conditions overnight into Thursday morning.
According to the National Weather Service in Grand Junction, a Freeze Warning remains in effect for portions of southwest Colorado where early Thursday lows could fall below 32°F. Breezy conditions are expected along the Colorado mountains, with calmer winds across valleys. Thursday warms quickly, with highs hitting 72°F under clear skies, but it’s a temporary reprieve.
By Friday and into the weekend, temperatures will rise sharply, reaching 80°F by Saturday in Grand Junction. But with the warmth comes instability: isolated afternoon showers and thunderstorms are likely late Saturday and Sunday, especially in higher terrain. Winds may gust up to 25 mph in the afternoons, impacting travel on U.S. Route 50 and I-70 through the Grand Valley.
Looking ahead, Monday night could bring another round of showers and storms, with more widespread precipitation early next week. Residents should secure outdoor items, check HVAC systems, and stay weather-aware as another low-pressure system approaches.
