FORECAST IN DETAIL

The humidity returned yesterday, and today it’s time for the warmth. If you’re into that sort of thing, I guess you’re in luck. If you’re in a building that’s already turned off the air conditioning, you’re out of luck. Warm and humid should stick around through midweek, but don’t expect much more than a pop-up shower or storm until rain chances rise Wednesday night into Thursday as some tropical trouble could affect our region.

Today (Sunday): Low clouds and fog are likely this morning but should mix out more quickly today than yesterday, leaving us with mostly sunny skies as we approach midday and into the afternoon. That sun makes a difference, too — pushing afternoon highs into the mid-80s. If I’m honest, it’s probably going to feel downright muggy at times, with light winds from the south pushing dew points into the uncomfortable low 70s. Confidence: High

Tonight: With a night expected to start off partly cloudy, we’re likely to see lower clouds and fog build once again with this humid air mass in place and little to no wind during the overnight hours. As such, it’s mild and muggy overnight, with lows near 70 to the mid-70s. Confidence: High

Tomorrow (Columbus Day): For those of us fortunate to have the day off, it is unfortunate that pool season has ended. The low clouds should be quick to burn off, but will probably be replaced by cumulus clouds building in the heat of the day, leaving us with partly sunny day with highs back into the mid-80s. Just a slight chance of an afternoon thunderstorm. Confidence: Medium-high

Tomorrow night: No surprises here, low clouds and fog should be on the rise. Lows should only drop back to the upper 60s to low 70s. Confidence: Medium-high

A LOOK AHEAD

The low clouds and fog may be a bit slower to burn off again on Tuesday, leading to a slightly cloudier and cooler day on the whole. Temperatures should manage to get to the upper 70s and low 80s. Skies should stay partly to mostly cloudy,

It should remain warm and humid on Wednesday with partly to mostly cloudy skies, highs in the low to mid-80s. There’s a chance of a few afternoon showers. We’ll need to watch a front approaching from the west and possibly a tropical system to the south, either of which could increase our rain chances Wednesday night or Thursday. Confidence: Low-medium
