Good Stuff.... It looks like our consecutive days streak with high temps above normal at National Airport is going to come to an end at 34. The normal high Today is 65 and I think it will struggle to get out of the 50s. It will feel even cooler than that with a good breeze coming out of the NE and occasional showers. The upper low to our west will continue to pump moisture up and over the stalled surface front in VA Today and Friday. You can see the set up on the water vapor loop clearly: http://www.ssd.noaa.gov/goes/east/eaus.html
Just click on the button that says "water vapor loop" on the right for that latest images. The area of high pressure we talked about yesterday in the Great Lakes will not be strong enough to suppress the clouds and precip as it passes into New England on Friday. The upper low will then lift out Saturday and keep the chance for showers going into the start of the weekend.  ¶ 8:22 AM
