#Philadelphia #weather #PAwx #PhillyWx
This week’s weather will continue to be warm/hot and very humid through at least Friday. With the exception of Monday, most of the weather will consist of random areas of thunderstorms developing from small, localized mesoscale disturbances.
On Monday, a weak, slow moving disturbance and upper trough will create somewhat more organized storms, especially towards evening. Some of that activity has been developing in Central PA this afternoon and may move into our immediate area, especially western sections this evening—
The upper trough and diminishing jet streak is visible with the GFS forecast for Monday morning—
Following any morning showers, Monday should become partly to mostly sunny through high clouds. Showers and thunderstorms move in from the west between 4 PM and 9 PM, but may lose upper support as they try to move past the city into NJ.
The rest of the week looks just like typical summer weather. Highs near 90 and VERY humid with scattered late day storms, too difficult to predict in advance.
Updates during the week. Stay tuned.
