Forecast Discussion: Current Conditions as of 1 PM on Friday: Light southeasterly flow has continued again today, ushering in just enough moisture aloft for some light cloud cover. PM 2.5 concentrations are hanging around the high good to low moderate range, and will remain similar to that through the duration of the weekend. *** Saturday’s Forecast: A weak cold front pushing east early in the morning will bring in drier air aloft; yielding mostly sunny skies for what should be a pleasant and dry weekend. Winds will become breezy out of the north during the afternoon hours. PM 2.5 concentrations will remain in the low moderate range for the early half of the day before falling into the good range as these winds increase mixing. Most locations will see concentrations average in the higher end of the good range for the day, but there will be scattered moderate levels. Highs for the day will be in the upper 50s to low 60s. *** Sunday’s Forecast: Mostly sunny and dry conditions will continue into Sunday. PM 2.5 levels will begin the day inside the good range. The breezy winds from Saturday will become lighter and more easterly to southeasterly as high pressure shifts eastward. Similar to that of Friday, a slight increase in moisture aloft may yield some light cloud cover. With the lighter winds and increasing moisture later in the day, PM 2.5 concentrations should return to the low moderate range by the late afternoon/evening. Highs for the day will be in the low to mid 60s. *** Monday’s Forecast: The southeasterly flow from Sunday will become more southerly on Monday, resulting in warmer and more humid air pushing north into the region. The flow will be a light breeze, so dew point temperatures will be slow to rise throughout the day. This should be the day with the most favorable conditions for moderate air quality over this forecast period. Light winds and increasing moisture will allow for PM 2.5 concentrations to sit well inside the moderate range. The area of high pressure that kept skies mostly clear over the weekend will weaken a little, resulting in potentially a mix of sun and clouds. Ozone concentrations may rise with forecast highs approaching the low 70s, but will be dependent on the amount of cloud cover. *** Extended Forecast: Moderate air quality will continue into Tuesday, but an approaching disturbance will bring increasing chances for precipitation. This precipitation does appear to be light and arrive later in the day at the present time. Therefore, it is expected that PM 2.5 levels will remain in the moderate range through at least the first half, if not three-quarters, of the day. Behind the approaching cold front, increasing winds should provide enough mixing to improve air quality conditions Wednesday and potentially Thursday. High pressure will return to the region late week. --- Roble
