As a high pressure system begins to pull away from the Northeast and mid-Atlantic coasts Friday morning, we will be watching the radar mosaic closely for the eventual development of some very light precipitation, primarily between the hours of 11 a.m. and 1 or 2 p.m. across the Greater Baltimore area.
As is often the case, whenever “overrunning” precipitation occurs, it is very light, but the vertical temperature profile of the atmosphere is suggesting that various places can see a touch of sleet or snow at the very beginning.
Therefore, if there are any slick roads or sidewalks out there, it will be during lunchtime, and then as temperatures rise during the afternoon — all forms of precipitation will quickly make the transition over to plain rain.
Rain late Friday will be relatively light, but its intensity will be ramping up Saturday, and a general 0.50″ to 1.00″ of rain should occur before all of it tapers off Saturday evening. Even though there is going to be a major winter storm developing off the coast on Saturday night and early Sunday, the odds once again favor that Boston and all of eastern New England will be “bearing the brunt” of it. We should encounter some gusty winds on Sunday afternoon, but there should also be a few hours of sunshine.
Have a good weekend !!!
