High pressure building across the region Wednesday into Thursday will allow for dry conditions for mid- week. ...Southerly flow sets back up across the area into Friday and the weekend with warm air advection in advance of a shortwave trough expected to move through the western US upper ridge and through the Northern Plains Friday.
