Weekend begins in Philadelphia with temps in 70s before Isaias impacts Sunday. Here's the weather forecast.
Saturday is the better of the weekend days in the Philadelphia area. It is the calm before the remnants of Hurricane Isaias arrive Sunday. Bright milky skies will require sunglasses, and by this afternoon, temperatures reach the low 70s.
Overall, it will be a pleasant day, so get out and enjoy and do any running around because Sunday will be a washout.
Saturday night will remain cloudy and dry through midnight with lows near 60. Showers will develop sometime after 3 a.m.
NEXT big weather changes
Leftovers can be good with food and money, but not so much with the remnants of a hurricane. Tropical remnants can be tricky and fluid as they arrive.
After making landfall Friday night, former Hurricane Isaias weakened and will continue tracking north, where it will interact with a cold front that steers the remnants toward us on Sunday.
NEXT Weather Alert for Sunday
A NEXT Weather Alert is in effect Sunday for periods of heavy rain and scattered storms.
Plan and prepare for indoor activities. One to three inches of rain are possible, with localized flooding likely. There will be gusty winds and a level 1 out of 4 for severe threats across far South Jersey and Delaware, where an isolated tornado or damaging wind gust is possible.
Rain should gradually taper off Monday morning as the remnants pull away, with some improvement during the afternoon. Temperatures recover into the lower 70s.
There's also a small severe weather concern, mainly across the southern counties. Wind shear and instability may be sufficient for an isolated severe thunderstorm Sunday afternoon or evening, particularly in Delaware and southern New Jersey. That threat is currently a Level 1 of 5, so it's something to monitor rather than the primary concern.
At the Jersey Shore, increasing easterly and southeasterly winds could create additional problems. Rougher surf and minor tidal flooding are possible Sunday into Monday, particularly during high tide. This does not currently look like a repeat of the prolonged coastal flooding and erosion event we experienced in September, but it's worth watching closely.
For weekend plans, Saturday is absolutely the better choice. If you have pumpkin picking, fall festivals, outdoor sports or anything else scheduled for Sunday, prepare for significant rain interruptions. Sunday afternoon and evening look like the most problematic period, although showers may begin much earlier.
Rain should gradually taper off Monday morning as the remnants pull away, with some improvement during the afternoon. Temperatures recover into the lower 70s.
Tuesday looks much better, with some sunshine and highs climbing back into the mid to upper 70s. Another cold front arrives around midweek, bringing a return to more seasonable October temperatures in the upper 60s.
The bottom line: Enjoy Saturday. Sunday looks increasingly wet, and localized flooding is our biggest concern as the remnants of Isaias move through.
