Tuesday, June 9, started like the kind of June morning Philadelphia wishes it could bottle: mostly clear skies, cool air around 55°F at dawn, and a comfortable climb toward a high near 83°F this afternoon. Low humidity will keep it feeling pleasant for outdoor plans and commutes, but the calm will not last long, with a turn toward more unsettled weather by Wednesday.
Afternoon Commute
Commuters get a relatively easy ride today. Southwest winds stay light this morning, then pick up to around 5 to 10 mph in the afternoon with occasional gusts near 20 mph. Roads should be dry and uneventful for most of the day. Local airports are expected to hold onto VFR conditions with good visibility, so flyers should not see much weather-related drama. Down the shore and along the rivers, rip-current and small-craft risks remain low for now, although that threat is expected to increase later in the week.
Wednesday Through Friday
Late Tuesday into Wednesday, a warm front starts dragging moisture back into the region and the atmosphere gets more restless. There is a chance of showers before 2 p.m. Wednesday, followed by more likely showers and thunderstorms between roughly 2 p.m. and 5 p.m. Most storms should be scattered and on the brief side, but any one of them could bring a quick burst of heavy rain or some lightning.
After that midweek shakeup, the real story becomes the heat. As outlined by the NWS Mount Holly, the latter part of the week turns hot, with Thursday and Friday expected to push into the low to mid 90s. Heat indices are forecast to climb into the upper 90s to around 100, a level that can be dangerous for older adults and anyone who has to work outside for long stretches.
Heat Safety
The City of Philadelphia urges residents to stay ahead of the heat rather than trying to tough it out. Check the latest cooling-center listings and call the PCA Heatline at (215) 765-9040 if you or someone you know needs help during a heat emergency. During the hottest hours on Thursday and Friday, roughly from midday into late afternoon, try to dial back strenuous outdoor activity, drink plenty of water, and keep an eye on elderly neighbors and pets.

Quick Take
Enjoy a dry, comfortable Tuesday, keep an eye out for midday storms on Wednesday, and get ready for potentially dangerous heat Thursday-Friday. This forecast will be updated if any advisories or heat headlines are issued.
