Having some minor (I hope) server issues today at Victoria-Weather HQ. That shouldn’t change the weather in Fort Collins, though, right? What can we expect in Northern Colorado this weekend?

At 956AM, MT, Fort Collins was reporting a temperature of 77 degrees with clear skies and a brisk north wind. There is a bit of shower activity across northern Colorado is associated with a cold front appended to an area of low pressure in western Ontario. A leading trough has switched winds to northerly across Fort Collins, but the boundary remained just to the north in southern Wyoming. Shower activity is largely found in the mountains west of Fort Collins and Cheyenne, though there will be some light activity as the day wears on, lasting into the morning tomorrow.
As the area of low pressure moves on to the east, high pressure will build in the Plains. In the southwest, warm air will begin to build again, and a laminar flow over the Rockies will lead to a down-slope and lee troughing in the Colorado flatlands. The contrast in air mass will lead to some ridge-riding thunderstorms in eastern Colorado by Sunday, but guidance and intuition suggest that the bulk of the activity will be south of the Palmer Divide, leaving Fort Collins mostly unbothered, but late in the period some activity could press into the area.

Count me in the “not likely” camp on Sunday thunderstorms. Everything right now just looks like it will show up too far to the south. Not today though, here is radar imagery, with showers heading in from Wyoming.
