Comfortable summer Sunday in Philadelphia area, tracking storms this week. Here's the forecast.
With a light east wind, the shore points this weekend may be the place to be! We're talking mostly sunny skies and very seasonable and comfortable temperatures.
The city and the mountains are right there too, with perfect mid-summer conditions lasting through Sunday evening. While the heat dome builds out west, our area sees normal and even slightly below-normal temperatures.
After this, get ready to sweat again. Humidity and storm chances return this week Monday, Tuesday and Wednesday. Tuesday is the day to watch for severe storms.
Temperatures will run below average in the low 80s, even upper 70s on Tuesday.
Thursday and Friday look mainly sunny and pleasant with an isolated storm in the afternoon on Thursday.
NEXT big weather changes
Plan, prepare and stay weather aware this week because severe storms are once again possible. A NEXT Weather Alert is in effect for Tuesday due to the threat of strong to severe storms.
An approaching disturbance will trigger some afternoon and evening storms on Monday. Some of these storms may briefly turn severe with damaging winds and flooding rain.
On Tuesday, an area of low pressure occludes overhead. The low pressure will remain overhead into Wednesday with wraparound instability showers and t-storms possible.
Here are the nuts and bolts of what an occlusion is:
- As the cold front catches up to the warm front over our area, they sort of zip together, creating a new front known as an occluded front.
- This meeting of the warm, cold and occluded fronts is known as the "triple point," an area that creates immense lift and spin in the atmosphere.
- Unlucky us, we are right under the triple point.
- Damaging wind gusts, flash flooding and isolated tornadoes are all possible.
- Don't be fooled by temperatures in the 70s on Tuesday. This severe threat will be driven by dynamics, not heat.
