Mid Summer Conditions for Mid Week
Winter outlook sneak preview
Matt Ross @ 8:30 AM
Mid week will feature what may well be our warmest temperatures until next May or June. The record highs for Today/Wednesday at National Airport (95/96) and Dulles (92/92) are likely safe, but nonetheless high temperatures will run 10-15 degrees above normal through Wednesday.
Mostly Sunny, Very Warm. Today will be sunny and warm with a touch of humidity. A throwback to the heart of summer, afternoon highs will reach the mid to upper 80s with a light breeze out of the south and east. Tonight will be clear and seasonably warm with overnight lows from the upper 50s to mid 60s.
Very Warm, Humid. Today has a shot at becoming our 42nd 90 degree day of the year (Average is 36-37). Prepare for unseasonable warmth and humidity. It will be sunny with a light southerly breeze and afternoon high temperatures in the upper 80s to around 90. Refer to Jason's forecast for the rest of the week and weekend.

Keith Allen, also known as KA, released his much anticipated winter outlook this past weekend. KA has been releasing DC area winter outlooks for 20 years now with a lot of success. KA predicts that December through February will feature well above normal temperatures with each month averaging 2 to 4 degrees above normal. He is calling for 10" of seasonal snowfall at National Airport (30 yr running average is 15.8"), with the majority falling in a 2-3 week wintry period. He is also predicting a major and a minor freezing rain event as well as a 70 degree reading in all 3 winter months. KA does concede that if the current La Nina event weakens as we head toward winter, that it will be colder and snowier than predicted. Currently, I agree with him for the most part, although I do believe that like last winter, one of the 3 months will feature below normal temperatures. CapitalWeather will issue its annual winter outlook in the next 4-6 weeks.

I DID SOME SEARCHES ON PCPN FOR THE CWA. THERE ARE 5 AIRPORT
REPORTING SITES - CHO, IAD, DCA, BWI, AND MRB. THE AVG PCPN DEFICIT
FOR THESE 5 THIS YR IS 10.6". CHO AND IAD ARE THE WORST - 16.46 AND
12.88".
AND SPEAKING OF IAD...SO FAR THIS YR THE AIRPORT HAS RCVD 18.45" OF
PCPN. THIS IS THE LOWEST ON RECORD SINCE 1962 (1986 IS 2ND AT 19.98).
