Southerly surface and transport winds this morning will shift to southeasterly this afternoon, with breezy conditions expected through sunset. These breezy conditions will yield fair daytime dispersion values today. Surface and transport winds will shift to southerly late this evening, with breezy transport winds expected before winds shift to southwesterly and then westerly overnight with decreasing speeds. Light west-northwesterly surface and transport winds are then expected on Saturday morning, with winds then shifting to southerly and southeasterly during the afternoon hours. Lighter transport speeds on Saturday will result in poor daytime dispersion values. .TODAY...
