As is usually the case with Alberta Clippers, this one did not produce a lot of precipitation. Snow accumulated on the tops of cars overnight, but the bigger problem has been the icy patches on area roadways. These ice patches should melt within the next couple of hours as temperatures rise above freezing. In typical clipper fashion, much colder air has invaded the state with freezing temperatures being observed well south of Montgomery. Other than a few passing clouds, skies should be mostly sunny today. Despite this, strong cold air advection will allow highs to top out around 38. Winds will gradually weaken through the morning and afternoon hours, but breezy winds will produce wind chills in the upper 20s.
Clouds will increase this evening as the main upper level energy grazes the area. Also, a few snow flurries may be squeezed out between 5 and 8 p.m. Winds will pick up again between 5 p.m. and midnight with gusts up to 30 mph. Looking upstream, there is an extensive stratus deck behind the clipper system. These low clouds should slowly shift eastward with the movement of the trough. I think clouds will begin to break after midnight with mostly clear skies by sunrise. As a result, temperatures will be very cold tonight with lows around 25.
