Forecast Discussion: Current Conditions as of 1 PM on Thursday: Brisk conditions continue today with storm system still just off the coast of New England. Breezy conditions will continue into Friday, but some clearing is expected. Temperatures will be near to just above normal through the weekend and into early next week. Friday’s Forecast: The storm system to our east that has blanketed the region with cloud cover and gusty winds over the past two days will move further offshore on Friday. Winds will remain breezy, just not as gusty as conditions Wednesday and Thursday. A mix of sun and clouds is expected early in the day with more sunshine than cloud cover likely by the afternoon. Temperatures are expected to climb into the low to mid 60s, slightly above normal for this time of year. PM 2.5 concentrations have mostly remained inside the good range the past few days and will continue to do so on Friday. A few isolated low moderate readings are possible. *** Extended Forecast: Saturday should be rather pleasant with the winds becoming a lighter breeze and plenty of sunshine overhead. A cold front will approach the region by the evening, but will lack enough moisture to produce much, if any, precipitation across this region. Lighter but more southwesterly flow may allow for more locations to see PM 2.5 concentrations climb into the low end of the moderate range than Friday. Breezy northwesterly flow on Sunday will help some of the locations that had more moderate PM 2.5 concentrations on Saturday fall back into the good range. High pressure will build over the region from west to east starting late on Sunday. Dry conditions look to continue through at least the early portion of next week before the next disturbance in this active pattern approaches. Mostly good air quality is expected over the extended portion of the forecast with some brief periods of scattered moderate levels. --- Roble
