Our week is very mid-Atlantic heavy, and we are in the throes of it, with a Thursday forecast for Roanoke.
At 554PM, ET, Roanoke was reporting cloudy skies and a temperature of 48. There was an area of low pressure off the coast inducing easterly flow over Virginia, which when hemmed against the Appalachians was creating ribbons of clouds over the plains that gave way to overcast conditions.
An area of high pressure will push it’s way south into the middle of the country, abutting a jet moving from the upper Mississippi Valley towards Chesapeake Bay. This will mean a few ridge riding showers at the base of the ridge developing tomorrow afternoon and rolling over the Appalachians into Roanoke. Expect mostly cloudy skies tomorrow evening into the morning Saturday. A very weak surface trough will develop within this activity and head towards the Southeast, which will create a bit of southeasterly flow and upsloping for Saturday in Roanoke. Showers and storms will become more widespread through the day on Saturday as a result.
