Forecast Discussion: FORECAST SUMMARY: Monday, May 18th, 2015 through Tuesday, May 26th, 2015 Ozone: 8-hour ozone concentrations will be generally Good through the forecast period. PM-2.5: 24-hour Fine Particulate concentrations will be mostly Good with some low Moderates possible late in the weekend. FORECAST DISCUSSION: A cold front passes through the state later Monday changing summer-like temperatures to readings well below normal by Tuesday. A northerly component to the wind remains in place through mid-week. This will keep cooler temperatures around, and surface high pressure will keep precipitation out of the forecast. Both fine particulate and ozone will be Good through Thursday. Surface high pressure remains the dominating weather feature Friday and Saturday as it slides overhead, then east of the state. Lighter winds Friday will change to the southeast Saturday. Temperatures will begin a small warming trend during this time; however, upper level readings remain cool. Pollution levels will remain Good for both fine particulate and ozone. EXTENDED FORECAST: For the end of the weekend and the Memorial Holiday, a warm front is forecast to bring the chance for showers and storms starting Sunday. A cold front will then pass through Monday, keeping showers and storms in the forecast. Southwest winds develop Sunday bringing in warmer temperatures and increased humidity. This could allow for some Moderate fine particulate levels; which could last into Monday in the east. The way is looks now, clouds and precipitation will keep ozone in the Good range both Sunday and Monday. Areas that may break into sunshine could hit Moderate for ozone on Sunday, but that does not look like much of a possibility. Colder temperatures and northwest winds move in later Monday/early Tuesday; Good pollution levels are expected.
