      After a delightful Saturday that warmed to the mid 80s and provided plenty of sunshine and very little humidity, today{}is suffering{}by comparison.{} While still comfortable, a retreating warm front and low pressure{}have conspired to produce{}showers and thunderstorms{}for much of the region.{}{}The system{}has the potential to bring even more rain overnight and throughout the day on Monday; highs tomorrow, like today,{}will{}rise only{}to the upper 70s.{} Thereafter, high pressure will return to D.C. providing mostly sunny late summer days with highs in the mid 80s.

      NOTE: Yesterday's 86 degree high and 69 degree low at Reagan National added up to the coolest day of the month of August.{} The 78 degree average was not only the coolest, but the only{}reading that exactly hit the statistical norm for the date. All the other days this month soared well above their averages.{} Enjoy your Sunday.
