The active pattern over the region continues as one storm system slowly departs Wednesday with a second system approaching Thursday. In the near-term, rain will continue through the first part of the day before tapering off early Wednesday afternoon.
Temperatures across the region range from 32 in Hagerstown to 41 in Salisbury at this hour, and some sleet will be found north and west of Baltimore early on, so some locations may see a few slick spots for the morning commute.
Again, precipitation will come to an end Wednesday afternoon with mostly cloudy conditions persisting overnight into Thursday.
A more significant system (an upper-level low) will move across the deep South on Thursday, and a surface low will develop over Georgia and head eastward through the day. As this occurs precipitation will spread northward along a frontal boundary and enhanced by a strong jet streak aloft.
Right now the Greater Baltimore area remains on the northern edge of the precipitation shield, but as we observed with the current system the trend has been for things to end up farther north. We shall see, but given that colder air will move in during the day Thursday, rain will likely change to snow before coming to an end Thursday night.
A light accumulation is possible (an inch or less), but there remains a good bit of uncertainty with that. Regardless, skies should clear late as the upper-level trough swings by with drier air moving in.
