Forecast Discussion: FORECAST SUMMARY: Monday, October 27th, 2014 through Monday, November 3rd, 2014 PM-2.5: 24-hour Fine Particulate concentrations will range between Good and Moderate Monday; then levels will generally average Good the rest of the forecast period. FORECAST DISCUSSION: Warmer temperatures on Monday and a southerly flow could produce Moderate fine particulate levels; mostly in southern parts of the state. Pollution levels will return to the Good range statewide Tuesday as a cold front passing through brings in cleaner air on a northwesterly wind. Chances for precipitation lingers Tuesday/early Wednesday with high pressure moving in as the front pulls away. Fine particulate will remain Good through mid-week. By late Thursday chances for showers comes back into the forecast as an upper level trough approaches. This trough will bring in cold air for this time of year, and on Halloween parts of the state may see the first snowflake of the season. Colder temperatures and northerly winds will keep fine particulate in the Good range. EXTENDED FORECAST: Surface high pressure moves in for Saturday with dry, but cold conditions. Winds turn southwesterly early next week as high pressure moves towards the east coast. The next approaching system could bring rain back in the forecast on Monday. Fine particulate late in the period will range from middle Good to low Moderate. Forecast updated by Stephanie Hengesbach: Monday, October 27th, 2014 Next forecast update: Monday, November 3rd, 2014
