Grand Junction, Colorado – Sweltering temperatures and afternoon thunderstorms will dominate Colorado’s weather starting Monday, setting the stage for rising river levels and possible travel disruptions. With highs nearing 90°F and storms firing along the Divide and I-70 corridor, travelers and residents should brace for rapidly changing conditions.
According to the National Weather Service in Grand Junction, isolated thunderstorms are expected Monday afternoon, primarily along and north of Interstate 70. Gusty winds up to 30 mph will accompany these storms, increasing the risk of difficult driving conditions on mountain passes and high-elevation routes.
The real concern builds midweek. As unseasonably warm temperatures persist, snowmelt from higher elevations will swell rivers and streams, potentially leading to minor flooding in low-lying areas. Those living near rivers like the Colorado, Gunnison, and Dolores should remain alert for fast-rising waters.
While Monday and Tuesday bring sunny skies and record-like warmth, conditions shift by Wednesday. A slight chance of afternoon thunderstorms returns, with temperatures falling to the upper 60s. Cooler weather arrives Thursday but won’t last long as summer-like heat rebounds by the weekend.
Five-Day Forecast for Grand Junction:
- Monday: Sunny and breezy, high near 90°F.
- Tuesday: High of 85°F, mostly sunny and windy with gusts up to 35 mph.
