Synopsis:
An upper level ridge will be kicked east due to a trough rapidly digging southeasard from the upper midwest. A warm but breezy Tuesday is in store ahead of the trough’s associated cold front early Wednesday morning. A dry adiabatic layer extending to 900mb will serve to mix the boundary layer and deliver breezy conditions in the afternoon. Continuing warm advection and moist mid level flow should support showers ahead of the cold front Tuesday night into Wednesday morning, with precipitation amounts ranging from a quarter to a half inch most likely. Skies should quickly clear due to rapid drying behind the front, bringing prime conditions for radiational cooling Wednesday night when the winds die down. Thanksgiving will be chilly but high pressure will keep skies clear.
