After tying a 1973 record high temperature of 93° yesterday at Philadelphia International Airport, it is expected to be another unseasonably very warm day in Philadelphia and the rest of the lower Delaware River Valley.
Peak temperatures are expected to approach 90° this afternoon and then the weather will begin to deteriorate.
Rain will begin to move in from the south and west late tonight as the remnants of Tropical Storm Hanna move up the eastern seaboard from the southeastern part of the country. Hanna is expected to make landfall along the North Carolina coast within hours and then spread plentiful moisture north and eastward. Tomorrow is forecast to be a rain soaked day and windy at times, but nothing like what coastal North Carolinians will deal with.
After the passage of what is left of Hanna, conditions will improve for a nice ending to the weekend a solid start to next week under fair skies and slightly cooler temperatures. See the National Weather Services statements for
more details on tomorrow's weather.
