Tuesday starts with some foggy and cloudy weather in the Philadelphia area ahead of a warm front that will lift northward.

The front will likely sit over the city by late afternoon, meaning areas north of Philadelphia will likely stay cloudy, foggy and cool all day.

Remember, if you have to drive through fog during your morning commute, turn your headlights and tail lights ON to make yourself visible to other drivers. On highways, follow at a safe distance.

Farther south, we will likely see some clearing and warmer temperatures. In the city we could go either way, a bit warmer than yesterday but not much clearing likely.

We could also see some spotty showers around the region but we're not expecting much rain.

By Wednesday, we're back in the 80s with a greater chance for storms, including a chance for an isolated strong to severe storm. Parts of our area are in a level 1 risk for severe storms, so we'll keep our eyes on it.

Thursday is a NEXT Weather Alert Day as a stronger line of storms may push through the Delaware Valley during the afternoon and early evening, bringing lightning, heavy rain and the possibility for severe weather. Most notably, the storms will bring the risk for strong winds, an interesting way to end spring as summer officially arrives on Friday, and wouldn't you know it, the pattern starts to shift just in time. 

We'll finally see a bump in temperatures heading into the weekend, with highs climbing back toward the mid to upper 80s and humidity sneaking in as well. It may not be a major heat wave into the weekend, but it'll definitely feel more seasonal and summer-like. So, if you're planning to kick off summer with a trip to the Jersey Shore or some backyard grilling, the timing looks just about right.

Get ready for the heat, though. Starting Sunday, we could be entering our first heat wave of the year. That means three or more days in a row hitting 90 degrees or higher, and this stretch could keep going into the following week.

For some context:

Because of the heat, we'll also be on NEXT Weather Alert Day for Monday as well, tracking feels-like temps of 100-plus degrees. Stay with your NEXT Weather Team for the latest.
