Forecast Discussion: Current Conditions as of 2 PM on Friday: Overcast and unseasonably cool conditions today will continue into at least the early half of the day on Saturday. Some light showers are trying to push north and westward into the region for this afternoon and evening. These showers will become a little heavier at times into the overnight hours and continue through most of the day Saturday. Overcast skies, rain showers pushing to the north and west, and a breezy northeasterly wind have held temperatures this afternoon to the low 50s. Drier conditions will prevail by late weekend, barring a sudden change in the expected out to sea track of Hurricane Joaquin. PM-2.5 conditions will remain in the good range for much of the forecast period. *** Saturday’s Forecast: Rain showers will continue into at least the morning hours with overcast skies expected for most of the day. A breezy northeasterly wind will continue to provide ample mixing for an already clean air mass. PM-2.5 concentrations will remain well inside the good range. Highs will once again be held to values well below normal as temperatures will be in the low to mid 50s. *** Sunday’s Forecast: A breezy east-northeasterly wind will continue, though temperatures will rebound with drier conditions for the day. Cloud cover will begin to thin out with potential to see some sunshine by late afternoon to evening hours. PM-2.5 concentrations will again remain well inside the good range. Highs for the day will be in the mid 60s. *** Monday’s Forecast: Increasing sunshine on Monday will help temperatures return to near normal values as highs will be near 70 degrees. The northeasterly breeze will continue, though will be lighter than what we will see over the weekend. PM-2.5 concentrations are expected to remain in the good range, but will climb higher than levels Saturday and Sunday. *** Extended Outlook: Similar conditions as Monday will continue through at least the middle of the week with highs near 70 degrees with a breeze. PM-2.5 concentrations will push closer to the good to moderate threshold on Tuesday, but should peak in the higher end of the good range. The best chance for moderate levels will occur in the Wednesday to Thursday timeframe, though breezy conditions will limit how far into the moderate range values will climb. The next disturbance to bring rain showers and a change in air mass is possible by the end of the week. This would return PM-2.5 levels to the good range for the weekend. --- Roble
