The danger of severe thunderstorms will spread to the Harrisburg area to start the new week.
While a shower or thunderstorm from the weekend will linger through Monday morning, Monday afternoon is when the atmosphere will be prime for the development of strong thunderstorms around Harrisburg.
The strongest thunderstorms will be capable of producing damaging winds, flooding downpours and some hail.
Extended disruptions to travel and outdoor activities can still be expected even in communities that escape damage and flooding.
Setting the stage for the thunderstorms will be the warm and humid air pour into south-central Pennsylvania.
Additional showers and thunderstorms will follow for Monday night and Tuesday. While the greatest threat for severe thunderstorms and flooding downpours will lie to the south and east of Harrisburg, flooding could still ensue from any localized group of thunderstorms that train over the same area.
The thunderstorms will finally press eastward Tuesday night, allowing a pair of dry and comfortable days to unfold for Wednesday and Thursday.
While the core of the September-like air plunging into the Midwest will lose some of its punch before reaching the I-95 corridor, Thursday's high will only be held about five degrees below the typical mid-July high of 86 F.
