Breezy northwesterly surface and transport winds at ignition time will continue to strengthen this morning, with speeds then gradually diminishing late this afternoon. These strong northwesterly winds will create good daytime dispersion values throughout the day. A dry air mass will remain in place across our area through the weekend, with long durations of humidity values around 30 percent forecast throughout the afternoon hours today and around 40 percent on Saturday. Northwesterly transport winds will mostly remain in the 10-15 mph range tonight and Saturday, with surface winds shifting slightly to west-northwesterly while diminishing to the 5-10 mph range. These lighter winds on Saturday, along with lower mixing heights, will result in fair daytime dispersion values at the burn site. .REST OF TODAY...
