The end of September was a dull, dreary day with plenty of clouds, cool temperatures and areas of rain and drizzle across the viewing area. Highs only topped to 64 at the Baltimore-Washington International Airport, the coolest day since it was only 60 on May 22!
While the upper-level low will finally start moving to the east this weekend thanks in part to an upper-level ridge building across the Central states, conditions will not get any better. The combination of high pressure over Atlantic Canada and moisture surging from the Atlantic Ocean will continue to bring plenty of clouds and areas of rain and drizzle. Highs on Saturday will again struggle to rise much but some areas could reach 70. Sunday may be the drier day across the viewing area as a tongue of drier air from the Deep South attempts to push northward up the coast. Some peaks of sun may break out Sunday afternoon. Should this be the case, temperatures could be quite warm.
A dry tongue will begin to cut off the moisture source with this low, therefore shower chances will become more isolated in nature on Sunday. While a shower can’t be ruled out, the best chance looks to be to the west closer to the upper-level low and across the Delmarva.
