Low pressure moving through the northern plains tomorrow will lift a warm front toward the region Thursday night. Warm air advection and moisture advection into the region will increase cloud cover Thursday evening with light precipitation possible after 2am. Precipitation should begin in the form of snow, but warm air advection will develop an elevated warm layer around 1470m that will change precipitation to sleet and freezing rain Friday morning. Surface temperatures will rise above freezing after 10am, ending the threat for icing.
We are only going to be looking at about .1" to .25" of water, which will be partitioned to around an inch of snow, a light coating of sleet, and a glaze of freezing rain on top. This, however, will be occuring right around the morning commute, so traffic may be slowed some Friday morning. Considering the timing, and if given a little more accumulation, we could have delayed openning on Friday.
