Summer beauty across Maryland Tuesday, dangerous heat to return
Humidity will begin to build Wednesday, but the heat will still be manageable, so we will enjoy another very good outdoor weather day.
The next round of heat and humidity begins to grow tough Thursday and turns potentially dangerous Friday through the weekend if heat preparations for the body aren't taken.
A strengthening ridge of high pressure will bring a return of very hot and muggy conditions to not only Maryland, but most of the Mid-Atlantic. High temperatures Friday afternoon will soar into the mid to upper 90s, and the heat index will likely surpass 100 degrees.
The WJZ First Alert Weather Team has declared Friday a First Alert Weather Day for potentially dangerous heat and humidity. Please add in plenty of water, breaks inside the A/C, and limiting time outdoors during the hottest part of the day.
The intense heat and extremely high humidity levels will continue into the weekend. Despite high temperatures a few degrees cooler than Friday, the air will feel even hotter with the incredibly high humidity levels. Highs Saturday afternoon will top out in the middle 90s with feels like temperatures 100° to 108°.
Sunday will be another sweltering hot and humid day with highs near 90° and feels like temperatures will top out near 100° to 105°.
A weak front may stall across our area or just south of us on Monday. Depending on the location of the boundary, more hot and muggy weather can be expected with highs in the upper 80s to lower 90s and feels like temperatures will into the 90s.
Highs this weekend will remain in the low 90s with tropical humidity, pushing heat index values near or above 100. Overnight lows will struggle to fall below the 70s. Any storms that develop will be capable of producing significant rainfall totals over a short period of time, raising concerns for localized flooding.
The combination of intense heat and humidity will be fuel for scattered to numerous thunderstorms Saturday and Sunday, especially during the afternoon and evening hours.
A weak cold front to our north will slowly ease south over the weekend triggering clusters of strong to severe storms. The strongest storms will have numerous and dangerous cloud to ground lightning strikes, blinding downpours, damaging winds, and hail. The WJZ First Alert Weather Team has tagged Saturday and Sunday as Alert Days for this combination of brutal heat and humidity along with the possibility of powerful storms.
Saturday the storms should be focused mid to late afternoon through the evening hours. Sunday the storms may develop a bit earlier in the day and continue into the mid-evening hours.
While this weekend won't be a washout, please keep an eye to the sky and if you hear thunder roar, go indoors. There have been large numbers of people struck by lightning this summer while enjoying time outside.

Monday will be hot, humid in Philadelphia region amid another heat wave. Here's the weather forecast.
Get ready for another heat wave! In fact, the high temperature of 91 degrees at the Philadelphia International Airport Sunday afternoon kicked off the fifth heat wave of the summer as temperatures are expected to peak in the mid-upper 90s through Wednesday afternoon. In addition to the heat and humidity on Sunday, the scattered showers and thunderstorms eventually cleared out to give way to mostly clear skies to start things off Monday morning. Temperatures will begin in the mid-70s across the region before warming into the low-middle 90s Monday afternoon. Just like on Sunday, the humidity on Monday afternoon will make it feel much warmer with feels-like temperatures soaring to near 100 degrees. While it will be unseasonably hot, it won't quite reach record territory with Monday's record high at 100 degrees. By Tuesday, the heat turns up even more with high temperatures across the region likely in the mid-upper 90s. The forecast for Tuesday and Wednesday in Philadelphia is for a high of 98 degrees, which would tie the record for both days. But what will it feel like? Along with the increasing temperatures, the humidity will also be on the rise, which will make it feel like anywhere between 100-105 degrees. When temperatures climb this high, it can be dangerous for anyone without adequate ways to stay cool and hydrated. As a result, the NEXT Weather Team has issued a NEXT Weather Alert for Tuesday and Wednesday to keep you aware of this dangerous heat. By Thursday, showers and storms will develop ahead of an approaching cold front that will put an end to this heat wave and usher in much cooler air by Friday. Friday is the start of August, and the start of an extended cooler stretch of air bringing relief from the heat through the first week of August. Highs Friday and into the weekend will be in the upper 70s to low 80s. Monday: Heat turns up. High 95, Low 74. Tuesday: NEXT Weather Alert for heat. High 98, Low 75. Wednesday: NEXT Weather Alert for heat. High 98, Low 77. Thursday: Storms end the heat. High 83, Low 77. Friday: Much cooler. High 79, Low 67. Saturday: Partly cloudy. High 81, Low 64. Sunday: Sunny skies. High 83, Low 62. NEXT Weather Radars Hourly Forecast

After humid, rainy day, family celebrating in New Jersey park is rewarded with a rainbow
The hot weather and even some rain didn't stop many from enjoying their Sunday night around the Philadelphia area. Under puffy white clouds, casting a line, taking a walk or even hosting a barbecue seemed like the perfect way to spend Sunday afternoon in Cooper River Park in Pennsauken, New Jersey. "We're sending off my grandson to DelVal University," Inez Nock said. "We're so proud of him. We have family and friends that came out." Nock's party eventually had to move under cover after rain started to fall in the park. "The weather didn't want to agree with us, but we're still here," Nock said. As the rain kept on coming, so too did the waterworks of a different kind — tears from a very proud grandma. Finally, there came a break in the clouds and a rainbow spanning the sky. "That's a blessing from God," Nock said. "He is going to watch over him for four years on his new journey of life." After the rain cleared out, many also ventured to Kelly Drive in Philadelphia to get in a workout as the sun was setting. Megan Feick is already thinking ahead to the hot weather on tap for this week and planning how to beat the heat. "Stay cool, everybody, stay hydrated. And you p robably won't see me out here very much," she said. As for George Gordon, who was out for a bike ride, he's taking it all one day at a time, grateful for the present. "I think we always need to appreciate every day that we wake up, air in our in our lungs and strength in our bodies," Gordon said.
