CommuteCast: Heat Maintains Its Grip on Area

Another 'triple H' day tomorrow, storms possible late

*Heat Advisory in effect until 8 p.m. Tuesday*
*Online chat transcript: It's Really, Really, Really Hot Out*
*Commuter Alert: Westbound Orange Line Train Derails in Va.*

The third straight 90-degree or hotter day has offered more in the way of uncomfortable conditions across the area. Highs this afternoon are now headed toward the upper 90s to near 100 degrees under mostly sunny skies, high dew points, and downsloping winds.

Tonight: We continue with clear skies and unpleasantly humid conditions overnight. Temperatures will fall from around 90 degrees at 9 p.m. to lows in the upper 70s in the city and the low or mid 70s in the suburbs. A light breeze from the south will at least keep the air moving a little during the evening hours, before going calm in some places overnight.

Tomorrow: Tuesday brings more haze, heat and humidity to the area, with maybe the beginnings of relief by late in the day in the form of thunderstorms. Temperatures will still reach the mid to upper 90s prior to any rain as winds blow from the southwest at 5-15 mph. Storms that form tomorrow afternoon and evening may be strong to severe, with the greatest risk being damaging wind and large hail.
