The month is ending on a comfortable note with temps slightly below normal. The average high for this date is 87 with an average low of 67 degrees. High pressure in the western Atlantic continue to influence our forecast.
The jet stream has carved out a deep noche ranging from the Canadian boarder through the Midwest and into the mid South. The airmass will allow us to stay seasonably cool through the remainder of the week.
A coastal front will form this weekend that will hamper the Delmarva beaches through Sunday and impulses from an upper level disturbance will flow in from the Great Lakes region. The combination of the two will present a chance for showers Friday morning and thunderstorms Friday afternoon. Shower chances persist into the weekend, but will stay closer to the shore by Sunday night.

South wind 5 to 7 mph. Chance of precipitation is 60 percent. New rainfall amounts of less than a tenth of an inch, except higher amounts possible in thunderstorms.
