-- Changed Discussion --
Evening convection has come to an end across the region with the weakening surface front lingering across nrn NC. There is little convergence along this front and with little in the way of upper level lift, do not expect to see much in the way of showers overnight. So have dropped pops down to slight chance in the south and removed any mention of pcpn for VA/MD. The satellite shows some high level cirrus lingering from the earlier convection...but this should continue to thin and move away from the area so expect to see mainly clear sky across VA/MD with a few more clouds lingering in the vicinity of the front. For temperatures, have dropped values several degrees at many sites as conditions should be similar to last night and also used 10 PM temps as a guide as well.
