Low Humidity Brings Relief to the East

After a muggy and stormy Labor Day, much of the East will be refreshed with lowering humidity through midweek.

The same cold front that brought afternoon showers and thunderstorms across the East on Labor Day will clear the Northeast Coast on Tuesday night. Another round of showers and thunderstorms will accompany the front as it passes through.

Cities such as Boston, Mass.; Providence, R.I.; and Bangor, Maine, have showers and thunderstorms in the forecast for Tuesday evening.

Additional rain could further aggravate flooding problems left over from Labor Day in the East.

In Cranston, R.I., heavy rain from thunderstorms left 60 people homeless when their houses were suddenly flooded. In the first two days of September, Providence already received almost 90 percent of the typical monthly rainfall.

However, in the wake of the front bringing these storms, low humidity will arrive in the region by the evening.

Dew points throughout the weekend were in the upper 60s to lower 70s across the Northeast, but after the passing of the front, dew points will be in the 50s along the coast and in the 40s over parts of the interior. Over a large part of the South, dew point temperatures will drop into the 60s.

The dew point is the temperature to which the air must be cooled to become saturated. Most people are comfortable with dew point temperatures in the lower 60s or lower in the summer time in the north and in the middle 60s in the South. The lower the dew point, the more quickly moisture evaporates from your skin.

The mid-Atlantic down through much of the Southeast will be feeling pleasant with at least some sunshine through Wednesday.

This high pressure will remain over the East for much of the week from Maine to the Carolinas. Farther south, the tail end of the front will linger along the Gulf Coast and bring showers and thunderstorms.

Looking forward to the coming weekend, another front will push through the Northeast. This will bring the chance for showers and thunderstorms and will be followed by even cooler air.
