The combination of an unseasonably mild and muggy air mass over the Northeast and moisture from distant Tropical Storm Maria is yielding yet another morning of thick fog and patches of mist and drizzle around the area – a very common scene across the Cape and Islands over the last week or so.
An influx of slightly more humid air over the last 12 hours and the addition of some mid and high level clouds spinning off of the circulation of Maria will result in a slower improvement to the gray morning skies versus the last couple of days. With that in mind, expect this morning’s dense fog and thick low cloud cover to slowly thin out and reveal some brighter skies as the morning goes on, with skies turning partly sunny during the afternoon hours – though fog will tend to linger along some of the beaches and coastline roads and overall today is looking “less sunny” than the last few afternoons.
Temperatures near 70F this morning (with matching dew point readings) will climb to the middle 70s for highs (higher if we manage to bust out into more prolonged sunshine), which is between 5 and 10F above the average for the date (68F at Hyannis).
If you are looking for a return of Fall-like air, you are in luck as a cold front is approaching the region from the north and west and will pass through the area tonight and tomorrow morning. Behind this boundary, a much more comfortable late September air mass will build into the Northeast and remain with us through the upcoming weekend.
