The diagram below shows the forecast weather map for Saturday morning. Note the intense low pressure system (the core of Draco) over upstate New York. Black lines indicate isobars, showing a packed pressure field (tight pressure gradient) over Baltimore. The colors show wind speeds at 5,000 feet. Yes, the forecast is for 60 mph winds not far above the surface on Saturday morning! Some of this momentum is expected to mix down to the surface on the day Saturday, causing very gusty conditions. Note the 70 mph winds close to mountain top height along the Appalachians.
To summarize, Draco's main impacts for Baltimore will start with bands of rain, followed by onset of strong winds, with wind chills down into the low 30's on Friday and Saturday.
