Forecast Discussion: A slow moving coastal storm east of the forecast area will drive very strong northeast winds on Thursday. This will effectively ventilate the metropolitan area with Good air quality expected. Extended Forecast: Continued strong northeast winds on Friday, although winds will diminish by evening. Good air quality will remain in place. Warmer and more humid on Saturday with winds shifting to the southwest. Particle concentrations will rise but remain in the Good range. -Ryan
