A dangerous heat and humidity combination will continue to grip the Lehigh Valley through Friday, with heat index values reaching 95 to 105 degrees. <\/p>\n

Severe thunderstorms are possible Friday afternoon, with damaging winds as the primary threat, according to the National Weather Service<\/a>.<\/p>\n

High temperatures are forecast to reach the low to mid-90s Friday, with dewpoints in the upper 60s to low 70s creating oppressive conditions. <\/p>\n

A Heat Advisory remains in effect through 8 p.m. Friday for Lehigh and Northampton counties and surrounding areas. <\/p>\n

The National Weather Service warns that this level of heat and humidity can become dangerous quickly for sensitive individuals and those spending extended periods outdoors.<\/p>\n

Temperatures reached 93 degrees Thursday at Lehigh Valley International Airport, according to preliminary data from the National Weather Service. Combined with relative humidity, heat index values rose to 101 degrees. <\/p>\n

High temperatures Friday are forecast as potentially slightly warmer than Thursday.<\/p>\n

Following scattered showers and thunderstorms Thursday night, Friday will bring another round of severe thunderstorm potential as an upper-level trough and cold front approach from the west. <\/p>\n

Showers and thunderstorms are most likely near and ahead of the cold front, with the entire region under a Slight Risk (2 out of 5) for severe weather<\/a>. <\/p>\n

The cold front moving through late Friday will provide significant relief heading into the weekend. <\/p>\n

Temperatures are forecast in the upper 80s to mid-90s over the weekend, but more importantly, dewpoints will fall into the 50s, making conditions much more comfortable. <\/p>\n

While it will still be hot, the humidity will be significantly reduced and no additional heat advisories are expected.<\/p>\n

Another cold front will approach Sunday night, bringing scattered showers and thunderstorms. <\/p>\n

This system will usher in a much more seasonable airmass for early next week, with highs in the upper 70s to mid-80s Monday through Wednesday and lows in the mid-50s to low 60s. Dewpoints in the 50s and low 60s will provide pleasant conditions through the middle of next week.<\/p>\n
