With temperatures in the 90's for the third day in a row, our first heat wave of the summer has come and is on it's way out. A cold front pushing it's way through the central part of the Commonwealth will bring relief, but first we have some storms to get through. Thunderstorms have already started firing, mainly in New Jersey, with warnings already being issued as well. Flash Flood Warnings also accompanying some of these storms as they already have started training on certain areas. The Excessive Heat Warning is still in effect until 5pm, at this time. The Storm Prediction Center also issued a Severe Thunderstorm Watch for the eastern third of Pennsylvania and the northern three-quarters of New Jersey until 9pm. There is another watch out for Delaware, Maryland, and the last third of New Jersey also until 9pm.
The showers and thunderstorms will become more numerous as we progress into the evening. The biggest threat with these storms could be strong gusty winds, heavy rain and frequent lightning. Lows will still hover around 70-degrees but after the frontal passage, with will become noticeably less humid. Winds will be out of the northwest at 5 to 10 mph, but within these thunderstorms, winds could pick up as high as 65mph. If you have outdoor plans tonight, keep an eye to the sky and make sure you are able to receive severe weather information on your phone. Tomorrow, showers could still be tapering off in the morning, otherwise cooler and less humid will be the rule for the day. Mostly sunny skies and the wind will have shifted from the north. Temperatures tomorrow in the mid- to upper 80's with some areas to the extreme south and east hitting 90-degrees again.
Sunday will feature increasing clouds in the afternoon ahead of another small disturbance. Scattered showers or thunderstorms could develop in the late evening and overnight Sunday into Monday. The start of the next work week will be mostly cloudy with showers and thunderstorms on and off most of the day. Starting Tuesday, temperatures will be below normal with mostly to partly sunny skies. In some areas, high's next week could be lower than some lows we experienced this past week. Quite a tranquil week ahead for the Philadelphia region after a bout of strong to severe storms to get through tonight.
