Forecast Discussion: Current Conditions as of 1 PM on Friday: Even though the start of autumn arrived yesterday, summer has decided to hang around for one more day. A cold front dropping north to south later today will bring a change in conditions that will feel fall-like for at least the upcoming weekend. *** Saturday’s Forecast: Seasonably cool and dry conditions will arrive for Saturday behind the cold front that pushed southward through the region late on Friday. Breezy northerly flow will usher in a cleaner air mass, resulting in PM-2.5 concentrations returning to the good range. Highs will be limited to near 70 degrees, which is close to where temperatures should be for this time of year. *** Sunday’s Forecast: Temperatures should dip into the 40s Sunday morning before returning to the upper 60s by the afternoon. Conditions will remain dry once again with the northerly breeze being a bit lighter than it was on Saturday. PM-2.5 concentrations will remain inside the good range. *** Monday’s Forecast: Seasonable and dry will continue into Monday under mostly sunny skies. The northerly flow may turn to be more southerly, but the air mass should be clean enough that it will not push PM-2.5 concentrations out of the good range or push temperatures much above the 70 degree mark. There is still some uncertainty in the track of an approaching cold front for late in the day on Monday. Should this front hold together as it approaches the region, it may bring our best chance for precipitation over the forecast period arriving Monday evening through the overnight hours. Should the dry air win out, we may see little to no rainfall with this front similar to the passage on Friday. *** Extended Outlook: Precipitation with the frontal passage or not, we will see a reinforcing shot of seasonably cool and dry air for Tuesday/Wednesday. Temperatures will continue to reach highs close to the 70 degree mark with overnight lows in the 50s. PM-2.5 concentrations should remain well inside the good range throughout the week with high pressure returning by late in the week. --- Roble
