Forecast Discussion: Current Conditions as of 1 PM on Monday: The active pattern continues again this week with what seems to be a never ending forecast of unsettled conditions this summer. Ozone concentrations again will be limited to the good range on Monday, but may try to approach low moderate levels Tuesday in areas that hold cloud cover off the longest during the afternoon. PM-2.5 concentrations remain at levels in the moderate range. *** Tuesday’s Forecast: Scattered showers and thunderstorms will continue into the early morning hours on Tuesday. We will then see a break in the precipitation, but more will arrive late Tuesday/early Wednesday. Breezy southwesterly flow will allow for moderate levels of PM-2.5 concentrations to continue with dew point temperatures on the rise. Early morning clouds with some areas seeing fog should clear to mostly sunny skies by the afternoon. Cloud cover will develop during the evening hours, but timing may determine how high ozone concentrations manage to climb for the day. The breezy conditions mixed with the early clouds and increase in the evening will limit peak values to the good range. *** Extended Outlook: Unsettled weather will continue for much of the remainder of the week with a daily chance for at least a few scattered showers. A mix of sun and clouds on Wednesday will keep ozone concentrations inside the good range. Locations that see heavier rainfall late Monday and again late Tuesday/early Wednesday will have PM-2.5 concentrations closer to the good range than areas that receive lower amounts of rainfall. At least low moderate concentrations are most likely through Wednesday without a true change in air mass and moisture levels remaining elevated. --- Roble
