Back to the 60s
Steve Scolnik @ 3:55 PM
The AC is off and the windows are open here at Afternoon Blog Central. Dewpoints throughout the Washington metro area are below the comfort limit of 65. Washington National wins the dryness derby with a reading of 55 in mid afternoon. Combined with a temperature of 85, that gives a relative humidity of 36%. Last night's official low of 68 was the coolest in about 3 weeks (since the 66 on July 24). Regional radar is clear for several hundred miles.
Outlook
Mostly clear skies tonight and relatively low humidity should allow low temperatures to reach the mid 60s. Tomorrow, strong sunshine and a more southerly wind direction will put highs into the upper 80s.
Irene Fading
Irene, which was a minimal hurricane with maximum sustained winds of 65 kt (75 mph), was downgraded to tropical storm (60 kt, 70mph) at 5pm. It is forecast to continue weakening and lose its tropical characteristics as it accelerates northeastward to latitude 60 N (between Greenland and Iceland) in the next several days.
The low pressure area formerly known as Tropical Depression 10 is still moving west-northwest about 350 miles east of the Leeward Islands. It is considered interesting enough to have a reconnaissance flight tentatively scheduled for tomorrow.
The most recent tropical wave to emerge off the African coast has a low pressure area associated with it and some scattered moderate to strong convection.
Yesterday's Rainfall
Rainfall amounts varied widely across the area yesterday. Dulles reported 0.46", but National had only 0.13". Amounts were higher to the south and east. Bob Ryan last night showed a couple of reports from the Woodbridge area with over 1".
