Much like the past couple of days, the ridge that has been building in from the west has been our main focus. Heat indices today have been sitting near 100 degrees and that will be the case as we head into tomorrow. Overnight, expect some isolated showers and storms across the area, but the best chance of rain will come as Sunday afternoon arrives. An upper level disturbance will move across the area and with ample amounts of moisture and an unstable atmosphere, fueled by the heat of the day, storms will develop. The best chance for any storms to develop look to be North of Highway 16 in Philadelphia. Along and south of I-20 looks to stay dry for the better part of the day tomorrow.
Relief is on the way as a new work week appears. The sun will quickly be replaced with clouds and showers and storms, as a very weak cold front makes it's way through the area. The best chance for any rain looks to be Tuesday into Wednesday as the front works it's way through the area. With the front creating lift, and dewpoints sitting in the 70s and an unstable atmosphere, everyone should see rain during some portion of their day.
By the end of the week, we will all dry out for the most part, with only 20 percent chance of rain staying in the forecast. We'll also begin another run back towards 90.
It's important to remember to always stay hydrated in the heat of the day, especially with the muggy conditions expected.
