AccuWeather: Spectacular Thursday on tap

PHILADELPHIA (WPVI) -- TONIGHT: It will be a cool and refreshing night with lows ranging from 50 in the suburbs to 57 in Center City. Perfect for opening the windows and getting some fresh air.

THURSDAY: High pressure continues to dominate our weather bringing sunshine and highs in the upper 70s with low humidity once again.

FRIDAY: That high is drifting to our southeast and the return flow around it will switch our winds to a more southerly component. This will lead to some warm advection high clouds, especially in the late day, and bring dewpoints back up into the low 50s. That is still very comfortable. Overnight Friday a warm front will moves through and with a strengthening low level jet at the time we have to be on the look out for a round of t'storms.

SATURDAY: The warm front Friday night will open the door to a hot and humid Saturday with highs near 90 and dewpoints in the mid to upper 60s. A weak cold front will approach late in the day and this will touch off some additional t'storm activity.

SUNDAY: The Saturday storms are gone and we end up with nice weather for Father's Day. We expect plenty of sunshine with a hot high of 90 and dropping humidity levels as we move through the afternoon. Sunday also marks the official arrival of summer at 11:32pm. It's the summer solstice when the sun's direct rays are directly aimed at the Tropic of Cancer, the northernmost point on the globe where this occurs. This also marks the day when we receive the longest stretch of sunshine; daylight hours begin to gradually shrink moving forward.

MONDAY: The hot weather continues with partly sunny skies and a high of 90. This could be the start of our second heat wave.

TUESDAY: It's warm and more humid with a mix of clouds and sun. We will need to watch for some tropical moisture pushing up from the south. At some point we will see some heavy downpours with not only the tropical energy, but a cold front arriving from the west. The high dips a few degrees to 85.

WEDNESDAY: A refreshing breeze arrives with a mix of clouds and sun. A nice high of 80.
