Hi-res guidance shows a few pockets of heavier precipitation will be possible along the eastern slopes of the Front Range this afternoon and evening. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Showers and storms are expected to linger into Sunday as an upper-level low traverses the region. Best chance for precipitation along the urban corridor still looks to be Saturday afternoon, with potential for a few stronger to severe storms to develop in the afternoon across the lower elevations that will contain an isolated threat for large hail and gusty winds. Quieter weather is still on tap for early next week, though isolated showers and thunderstorms will still be possible each afternoon. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today or tonight, but reports of gusty winds and hail will be appreciated. $$
