The weather, currently.
The weather forecast for Wednesday in the City of Philadelphia is for some very light snow possible before sunrise. Temperatures will be cold enough that any snow which does fall should stick, but it will be a dusting at most. Temperatures start off around 30°F at sunrise, and will reach the upper 30s during the afternoon. Skies start off cloudy during the morning hours and become partly cloudy during the afternoon. Overall, a very typical day for the start of February.
Looking ahead, Thursday will be a dry day with similar temperatures. And then the Arctic boom is lowered, with much colder temperatures and strong winds for Friday into the weekend. More details coming up in the Thursday forecast.

The planet could cross the critical global warming thresholds much sooner than expected even if emissions quickly decline, according to a recent study using machine learning.
In other words, climate change is happening coming faster than scientists and meteorologists predicted and time is running short to stop the worst effects from this intense heating.
Researchers at Stanford University and Colorado State University found that 1.5 degrees C of warming over industrial levels will likely be crossed in the next ten years. The study also revealed that the planet is on track to exceed 2C warming, which scientists have marked as a tipping point, with a 50 percent chance it would be met by mid-century.
“We have very clear evidence of the impact on different ecosystems from the 1C of global warming that’s already happened,” told Stanford University climate scientist Noah Diffenbaugh, who co-authored the study with atmospheric scientist Elizabeth Barnes, The Guardian. “This new study, using a new method, adds to the evidence that we certainly will face continuing changes in climate that intensify the impacts we are already feeling.”
Using artificial intelligence, or AI, scientists analyzed different global climate warming model simulations and then determined warming timelines for given temperature thresholds.
Though half a degree doesn’t sound like much, its effects would be catastrophic. The chances of extreme flooding, drought, wildfires, and food shortages will increase greatly. Heatwaves will become more severe and frequent as well.
However, according to Diffenbaugh, there’s still some time to turn things around.
“Managing these risks effectively will require both greenhouse gas mitigation and adaptation,” he told The Guardian. “We are not adapted to the global warming that’s already happened and we certainly are not adapted to what is certain to be more global warming in the future.”
He continued: “Stabilizing the climate system will require reaching net zero, he said. “There are a lot of emissions globally – and it’s a big ship to turn around.”

Climate change is making wildfires worse, damaging our communities and the environment. Not only do wildfires hurt our forests and put people in danger — burn scars can result in harsher floods — like we’ve seen in recent weeks across California.
Our partner Wren supports efforts to prevent wildfires by removing flammable, dead wood and turning it into biochar — removing carbon in the process. Join Wren to start funding climate solutions today, new users get 20 native trees planted for free on us.
