Tuesday in Philadelphia will be warm as Canadian wildfire smoke blankets parts of region. Here's the forecast.
Canadian wildfire smoke will lend a hazy appearance to the sky, and high clouds will blanket much of the region, filtering the sun and slightly limiting Tuesday afternoon warmth.
The smoke will likely be with us through Wednesday, as the winds are expected to bring the smoke into our area. Those northerly winds, however, will keep our humidity levels moderately low for this time of year, so at least that's a bonus.
A Code Orange Air Quality Alert is in effect for our region in Pennsylvania, meaning the air quality could be unhealthy for sensitive groups, such as those with lung disease, the elderly or the very young. The alert is in effect through midnight.
Tuesday stays warm and dry, with highs near 90 and a bit more humidity under partly cloudy skies. It may brighten a bit in the afternoon, but clouds will build Tuesday evening as moisture moves in on an onshore flow.
Another earthquake today in New Jersey
Shortly after 12 p.m., a 2.7 earthquake shook near Hillsdale, New Jersey, on Tuesday, the U.S. Geological Survey said.
The earthquake hit about 7.7 miles deep, about 1.25 miles southwest of Hillsdale, according to the USGS.
Tuesday's incident comes on the heels of a 3.0-magnitude earthquake in Bergen County's Hasbrouck Heights Saturday night that rattled parts of New Jersey and New York.
Looking ahead to the rest of the week
Wednesday looks cloudy much of the day with an onshore flow, keeping things on the cool side for early August.
Thursday brings brighter conditions as high pressure noses in from the northwest, and we'll start to warm up, with highs returning to the upper 80s by the weekend.
Other than a stray shower chance, mainly south of the city, we'll be on a fairly dry stretch to start August.
