Showers and thunderstorms are ramping up to more widepsread coverage and intensity.
Storms are firing off the High Country on Wednesday afternoon and as such have a northwesterly drift. There is already a Flash Flood Watch for the “GRIZZ” and if it goes to a warning status, the Interstate will close. This is going to be commonplace as we continue through this workweek, the upcoming weekend and into the start of next week. Expect closures and delays due to heavy rain rates and subsequent flooding issues.
The isolated storms for Wednesday evening will contain small hail in the higher elevations, lowered visibility on roads due to heavy downpours, cloud to ground lightning and very gusty wind speeds. This storm activity is expected to last past sunset/slightly longer into the midnight hour. The storm focus is the San Juans, but NOT confined to that area. Thursday will start hot and muggy with much of the same storm development and subsequent hazards as the day pushes toward night. Plenty of showers and thunderstorms in the extended forecast due to the classic setup of a high pressure system to our east and a low pressure system to our west. This is an unavoidable North American Monsoon pattern. The strength and frequency of these daily storms will intensify as we move through this weekend. If you plan on traveling this weekend and early next week, please be prepared for road closures/detours due to “flashy” weather situations. The chance for scattered afternoon thunderstorms is expected to die down after the middle of next week.
