Warm, a little more humid. Weak southerly flow both aloft and at the surface east of the low pressure area stuck over the Great Lakes and Ohio Valley is bringing in slightly more humid air this afternoon. Temperatures in the mid 80s and dewpoints in the low to mid 60s are not oppressive for late July, however. Shower activity is extremely spotty through the entire Mid Atlantic region.
Tonight and Tomorrow
Warm, humid, slight chance of showers. Humidity will continue to gradually increase through tomorrow. After a slight chance of showers through this evening, lows tonight will be in the upper 60s to near 70° downtown and in the mid 60s in the 'burbs. Tomorrow will be a little warmer with highs 86-90° and a slight chance (20%) of afternoon or evening thundershowers.

"Simply replacing the director will not resolve the center's workplace issues. If staff morale and long-standing organizational issues are not addressed, they will hinder the center's longer-term ability to accomplish its mission."
