Discussion
The combination of hot and humid conditions, energy in the upper atmosphere, and a stalled out frontal boundary zone will increase chances later today for showers and thunderstorms and that threat will continue tonight as well. Given the unstable atmospheric conditions in the Mid-Atlantic region, any storm that does form can reach strong-to-severe levels with gusty winds, hail and heavy rainfall. Another frontal system will approach the region on Thursday and this too will bring about a chance for showers and thunderstorms and some of these storms can be strong-to-severe as well. Following that next frontal system, some relief of the heat and humidity will arrive on Friday and it’ll remain rather seasonal on Saturday as well. Heat and humidity will build back into the region early next week as high pressure pushes off the eastern seaboard and a west-to-southwest flow of warmer and more humid air develops around here.
