With a northerly wind we reached 74 at Philly International Airport after a low of 55. The day was sun-filled, but then were some clouds in the afternoon with a sprinkle north and west. Overnight will feature a few clouds with lows in the lower 50s.
Saturday will be sunny, but there will be an onshore wind the closer to the coast you go; in Center City itself the wind will be out of the north so highs will be in the lower 70s. There may be some clouds in the afternoon once we reach our convective temperature(the estimated temperature that the surface must warm to in order for clouds to develop) with that short wave lingering just offshore, but we shall stay dry. After an overnight low in the middle 50s we'll reach the middle 70s on Sunday with plenty of sunshine.
Come Monday we're back into the lower 80s with continued sunshine, but overnight into Tuesday clouds increase ahead of a cold front; we will be flirting with 90 with showers and thunderstorms in the afternoon through the overnight with lows around 70. Wednesday will feature residual showers and t-storms in the morning, but gradual improvement in the afternoon. So with a westerly wind I think we'll still be in the upper 80s.
