Discussion
A warm front is passing through the region this morning with some shower and thunderstorm activity across the northern suburbs and it'll turn warmer and more humid as the day progresses. In addition, as a cold front approaches early tonight, this change in air mass will set the stage for potentially strong-to-severe thunderstorm activity later today and tonight across the Mid-Atlantic and Northeast US. Low pressure has pushed northeastward out of the central Plains and into the western Great Lakes and it will take a sharp right turn later today and heads towards the Northeast US. This low pressure system will strengthen as it approaches the NE US into what is likely to be a rather favorable environment for severe weather, including the risk of tornadoes. High pressure takes over on Friday and the work week will end with lowering humidity and comfortably warm conditions.
