The forecasts from yesterday (Wednesday) morning called for a short-wave trough to skirt us just to the north, with cooler, drier air moving into northern utah on Saturday morning. Precipitation in northern Utah was very limited, with only a very small are of light precipitation on the north slope of the Uinta Mountains in the NAM.
The net impact of such a shift is an increase in the forecast cloud cover over northern Utah and an increase in the possibility of precipitation over the northern part of the state, perhaps mainly in that area near the band.
As forecasts shifts go, this is a minor one for most day-to-day activities, but I'm desperate for material, so give me props for the effort! In addition, when we start thinking about the management of power generated by alternative energy sources, such as solar, subtle changes in the forecasts can be very significant. Those thin cirrus clouds that most of us hardly notice for our day-to-day activities can dramatically reduce solar energy production and are damn tough to forecast.
