Meteorological autumn arrived on Sept. 1, marking the 90 days between the warmest and the coldest seasons of the year. Typically we would find mild days and crisp cool nights as the dominating weather during this period, but this year is continuing a trend of milder-than-average falls. A cold front passed off the coast overnight and now less humid air is arriving from the west. It’s still muggy this morning, but the 70-degree oppressive humidity is being shunted out to sea. Temperatures today will reach the 70s and many places in the upper 70s. This will be the case right to the coastline on a westerly flow of air. These temperatures are 10-18 degrees above average and more typical for early to mid-June. Highs Tuesday will be more typical for summer, not autumn.
