PHILADELPHIA (CBS) – Tuesday will be very similar to Monday. The heat and humidity will “stick” around for one more day, and thunderstorms will once again pop up this afternoon.

Patchy fog this morning is beginning to thin out, revealing mostly cloudy skies, with some breaks of sun. We expect to hit 90 degrees, which would make it the 4th time in the last six days (the other two days hit 88 and 89, so while not an official heat wave certainly a sultry stretch). Any afternoon storms will be scattered, popping up along a cold front during the early afternoon hours. Although the threat for severity is low, downpours, lightning, and small hail are all still very possible. Once this front starts to pull away this evening, skies will clear and it will begin to fell less humid.

Down in the Gulf of Mexico, Tropical Storm Bill is preparing to move ashore in Texas. From there, it will dump several inches of rain through much of Texas and into the central United States. This moisture will eventually reach the Delaware Valley in some capacity. It could accelerate and reach us at some point on Saturday or get picked up by a frontal boundary and reach us towards the end of the upcoming weekend, so it will definitely be something we will follow closely over the next couple of days.

Latest Forecast:

  • TODAY – Partly Sunny, Hot and Steamy with a Few Afternoon Showers and a Locally Gusty T-Storm. High 90.
  • TONIGHT – An Evening Shower or T-Storm, Then Partly Cloudy. Low 68.
  • TOMORROW – Mostly Sunny and Less Humid. High 85.
  • THURSDAY – Mostly Cloudy with a Shower or T-Storm. High 80.
  • FRIDAY – Partly Sunny with a Chance of a Shower. High 86.
  • SATURDAY – Partly Sunny with a Chance for Rain and a T-Storm. High 85.
