Grand Junction, Colo. – Lightning and gusty winds could threaten areas north of I-70 this afternoon as isolated to scattered thunderstorms develop across western Colorado’s higher terrain. The greatest impacts are expected along the I-70 corridor from Glenwood Springs to Craig, where conditions may shift rapidly after 2 p.m. Sunday.
According to the National Weather Service in Grand Junction, a weak boundary dropping out of Wyoming is triggering storms mainly north of the interstate. While rain totals will be light, forecasters warn that lightning and sudden outflow winds are the main hazards. Areas to the south, including Grand Junction and Montrose, should see calmer, drier conditions with less wind than Saturday.
Communities such as Steamboat Springs, Meeker, and Rifle may experience brief weather disruptions, particularly in outdoor or high-elevation areas. Residents are urged to avoid exposed spaces during storm activity and secure loose outdoor items. Storms could also impact recreation in national forests and high-country trails.
Temperatures remain around 5 degrees above average across the southern half of the state, while areas north of I-70 will see near-normal readings in the mid to upper 70s.
Isolated storm activity may linger into the evening, with updated advisories possible if conditions intensify.
