Before the showers and severe thunderstorms we managed to reach 91 at Philadelphia International Airport after a low of 75 in the morning. As far as rainfall goes the airport has measured 0.79" as of early Tuesday evening, but the overnight climate report will reflect not only the low in the lower 70s before 11:59, but also higher rainfall amounts that fall as well.
There will be scattered showers and thunderstorms overnight, but the severity chance shall be low as the best dynamics are now offshore, BUT that doesn't mean we still can't have heavy downpours. There is a reason why there is a Flash Flood Watch in effect for the entire region until sunrise! After the showers end by the morning commute the clouds shall push away as well; we will have sunshine by the afternoon with a northwesterly wind as highs will be in the lower 80s. The humidity will be dropping by the afternoon as well and it will feel AMAZING!
After lows in the lower 60s with a mostly clear sky we'll have a rough time trying to reach 80 degrees on Thursday; after lows in the upper 50s we'll be into the lower 80s to round out the work week with continued lower humidity. Come Saturday an area of low pressure will start sliding up the Appalachians and we'll have increasing clouds in the afternoon with highs in the middle 80s; the rain shall hold off until overnight and Sunday with lows in the upper 60s and highs in the middle to upper 80s. Scattered showers and thunderstorms will linger into the afternoon and evening going through Monday as this stationary front is very slow to push eastward. It finally does by overnight Monday and sunshine will return for Tuesday....
BUT highs will be in the upper 80s as we'll have high pressure and a southerly wind.
