One last gasp of heat and humidity?

Summer may technically be over with, but summer-like sticky weather is expected to last through the week in Baltimore.

Dew points haven't fallen below 70 degrees at BWI Marshall Airport since Saturday. With temperatures only in the 70s and 80s mostly since then, that meant thick, wet air over Labor Day weekend.

The dew point takes into account both the relative humidity and the air temperature, giving a better picture of how humidity feels -- and anything above about 65 feels pretty uncomfortable.

Tuesday and Wednesday, dew points are forecast to remain in the lower 70s. Thursday, Friday and Saturday they could drop to the upper 60s. Highs will flirt with 90 degrees some days.

The heat and the moisture in the air could contribute to scattered storms over the week.

By Sunday things are expected to get cooler and clearer, with temperatures currently expected to top out around 80 degrees and dew points in the lower 60s, according to the National Weather Service.

Average temperatures are around 80 degrees in September, though records are still in the 90s through the month.
