Another very warm and muggy night is in the forecast for tonight. A spotty shower or thunderstorm is possible, but most places will stay dry. Lows will be around 80 in Center City and in the 70s in the suburbs. The heat index won't drop much below 90 as dew points hold in the low to mid 70s overnight.
Saturday will start with hazy sun before clouds build in during the afternoon. This will be the last day of our extended heat wave as highs reach the mid 90s once again. The heat index will be between 100 and 105 at the hottest time of the day. As a cold front approaches, showers and thunderstorms will arrive from northwest to southeast late in the day. Some storms have the potential to become strong to severe, so be sure to keep an eye to the sky if you have plans Saturday evening.
Sunday won't feel quite as humid, but the air behind the cold front really isn't that much drier. Most of next week will still feature dew points between 65 and 70, making it feel a bit humid outside (but not nearly as humid as the end of this week). A few showers or storms are still possible on Sunday, but it is still looking like the drier and cooler half of the weekend.
A series of weak low pressure systems will affect our weather next week. Monday through Thursday all feature the chance for showers and thunderstorms, but no day appears to be a complete wash-out right now. We may finally start to see some improvement by Friday.
