The passage of a cold front Monday brings a stretch of cool, dry weather starting Tuesday, with temperatures perhaps failing to top 80 degrees after matching a record low overnight.
Baltimore-Washington International Thurgood Marshall Airport dropped to 59 degrees early Tuesday morning, matching a record dating to 1978. It is the fourth time this month a low-temperature record has been tied or broken at BWI.
Temperatures reached 70 degrees by midday at BWI, about 3 degrees warmer than normal overnight lows for this time of year.
Mostly sunny skies are forecast, with overnight lows in the 50s to lower 60s and afternoon highs only in the upper 70s, about 10 degrees cooler than normal for this time of year, according to the National Weather Service.
Similarly cool lows and highs in the lower 80s are forecast Wednesday and Thursday, with sunny skies.
Low humidity is forecast throughout the stretch, with dew points in the 50s.
Some storm chances and cloudy skies move in Friday, with highs still in the lower 80s.
